The Antelope Valley (Study Area) is a westward extension of the Mojave Desert in northern Los Angeles County (Caltrans District 7) and southeastern Kern County (Caltrans District 9). The Study Area covers 5202.71 square kilometers (2008.78 square miles). The focus of this study is the archaeological record of Native Americans in this region from initial occupation until AD 1835 (the end of the Mission Period). The purpose of the contexts and theme discussions (with research questions and data needs) provided herein is to assist with evaluations of the information potential of Native American archaeological sites in the Antelope Valley. This document will need to be updated periodically to reflect future advances in archaeological methods and theory, as well as to incorporate the results of future archaeological investigations in the Antelope Valley. Specifically, this document provides the Department a framework for evaluating archaeological properties from the Antelope Valley for eligibility for the National Register of Historic Places (NRHP) under Criterion D. To be eligible under Criterion D, NRHP guidance states that a property must have, or have had, information to contribute to our understanding of human history or prehistory, and the information must be considered important (see Title 36, Part 60, Section 60.4[d] of the Code of Federal Regulations [36 CFR 60.4(d)]). This research design focuses solely on Criterion D; the Department, in consultation with Native American communities and other stakeholders, must consider whether other National Register criteria apply to individual sites. The NRHP Bulletin series is an essential reference for researchers when applying the NRHP criteria for evaluation of cultural resources. This research design may also be used in evaluating a property’s eligibility for listing in the California Register of Historical Resources (CRHR). The CRHR eligibility criteria are nearly identical to those of the NRHP, but some properties not eligible for listing in the latter may qualify for listing in the CRHR. Structure of the Research Design This document provides information about the natural and cultural setting of the Antelope Valley Study Area, the theoretical orientation used in the research design, and presents research themes, along with research questions and data needs that can guide archaeological investigations. The natural setting includes information about topography, geology, hydrography, climate, vegetation, and fauna. The cultural setting provides information about chronology, ethnohistory, previous archaeological investigations, and geoarchaeology. The theoretical orientation section presents Archaeological Research Design for the Antelope Valley Study Area 1 07A3822 Task Order 17 discussions of the main archaeological theoretical perspectives of cultural materialism, optimal foraging, the collector-forager model, subsistence intensification and storage of resources, and human behavioral ecology. Research themes that can be used to structure future archaeological research in the Antelope Valley include paleoenvironmental reconstruction, settlement systems, subsistence, exchange and conveyance, lithic technology, lithic sources, population movements, and social differentiation. Research questions and the kinds of data necessary to address these questions are provided for each theme. Archaeological Research Design for the Antelope Valley Study Area 2 07A3822 Task Order 17 NATURAL SETTING Archaeological Research Design for the Antelope Valley Study Area 3 07A3822 Task Order 17 Current Landscape Geographic Limits of the Antelope Valley The Antelope Valley is a V-shaped internal drainage basin and a western extension of the Mojave Desert. It is located in the northern part of Los Angeles County and the southeastern part of Kern County, California, and covers an area of 5202.71 square kilometers (km2) (2,008.78 square miles) (Figure 1). The San Gabriel and Tehachapi Mountain Ranges form the western, southern, and northern boundaries of the Antelope Valley. The eastern boundary, however, is more amorphous and is marked only by a few buttes as the Antelope Valley transitions into the central Mojave Desert (Earle et al. 1997). Multiple methods can be used to define the eastern boundaries of the Antelope Valley. For the purposes of this research design, a combination of watershed boundaries and ethnographic boundaries were used to define the area referred to here as the Antelope Valley Study Area (Study Area) (Figure 1). The Study Area is defined as follows: the Valley’s northwest boundary is defined by the foothills of the Tehachapi Mountains (Figure 2a); the northern boundary runs from the mouth of Oak Creek Canyon in the foothills of the Tehachapi Mountains, eastward along Oak Creek Road and SR-58 to the San Bernardino County Line, and immediately south of Fremont Valley (Figure 2b); the southern boundary runs along the foothills of the San Gabriel Mountains, Sierra Pelona, Sawmill Mountain, and Liebre Mountain to Quail Lake (Figures 2c and 2e); the eastern limits are based on drainage patterns and roughly follow the county line between San Bernardino County and Los Angeles County, running southward to Moody Springs, and finally to Pinyon Ridge in the foothills of the San Gabriel Mountains (Figure 2d and 2e). The Study Area also includes a portion of the San Andreas Rift Zone and the Little Rock Creek Watershed in the San Gabriel Mountains. Geology and Topography The Antelope Valley is located in the Mojave Desert province of Southern California. This region is a southern subsection of the Basin and Range physiographic province characterized by north/southtrending mountain ranges separated by broad alluvial valleys. Predominant landforms within this province include isolated mountains and ranges, separated by basins with alluvial fans, playas, and dunes (Bornyasz 2014). The Antelope Valley is an approximately 5,000 km2 basin formed by movement along the Garlock and San Andreas Faults (Ponti 1985). The Garlock Fault uplifted the Tehachapi Mountains to the north, and the San Andreas Fault uplifted the San Gabriel Mountains to the south. These two mountain ranges form the northwestern and southern boundaries of the Vshaped Antelope Valley. The uplift of the Tehachapi and San Gabriel Mountain ranges isolated the Antelope Valley from the coast and created an interior drainage basin. The formation of this interior drainage basin likely resulted from the uplift of the San Gabriel Mountains approximately 1 to 2 million years ago, which closed off Tertiary drainage routes from the Tehachapi Mountains to the ocean. Due to this recent uplift, the Antelope Valley almost entirely filled with Quaternary sediments (Ponti 1985).

Drainages from the mountains run across the valley eastward toward Rosamond Lake, which forms the low point of a closed basin in the western Mojave Desert (see Figure 1). The drainages and Rosamond Lake are dry except during flood episodes. There are several hills and buttes that rise above the valley floor including Fairmont Butte, Little Butte, and Rosamond Hills. These buttes are predominantly Tertiary in age and are composed of quartz monzonite, volcanic felsites/rhyolites, and fanglomerates. Several of the buttes contain tool-quality felsite/rhyolite, chert, and jasper. The San Andreas Rift Zone runs along the south side of the Antelope Valley. The rift zone is in a long linear valley that runs along the basal slopes of the Bald Mountain, Liebre Mountain, Sawmill Mountain, and the Sierra Pelona chain of mountains. The rift zone is separated from Antelope Valley by Portal Ridge and its extensions which run parallel with the rift zone. Hydrology The Study Area lies within the Antelope-Fremont Valleys Watershed (Bornyasz 2014). The AntelopeFremont Valleys Watershed (2,160,629 acres) is predominantly within Kern and Los Angeles Counties and extends from the community of Boron west to the community of Mojave and south to the Lancaster-Palmdale area. The most hydrologically significant streams in the Antelope Valley region begin in the San Gabriel Mountains on the southern edge of the Antelope Valley Region and run onto the valley floor. They include, from east to west, Big Rock Creek, Little Rock Creek, and Amargosa Creek. Cottonwood Creek and Oak Creek drain from the Tehachapi Mountains. All of the drainages recorded within the Antelope-Fremont Valleys Watershed are considered to be isolated and flow toward the three dry lakes (Rosamond Lake, Rogers Lake, and Buckhorn Lake) on Edwards Air Force Base. Except during the largest rainfall events of a season, surface water flows quickly percolate into stream beds and recharge the groundwater basin. Surface water flows that reach the dry lakes form shallow pools that can last for several months but are eventually lost to evaporation (Bornyasz 2014). The topography of the Antelope Valley creates an internal drainage basin wherein, in modern times, the wet season’s water is absorbed in place. There are several active creeks south and east of the valley, but only ephemeral drainages within the valley. Due to the high percolation ability of sediments within the Study Area, rainfall tends to be absorbed into the groundwater aquifer before reaching the valley interior. Until recently, the groundwater level within the Antelope Valley was relatively shallow. Drilling operations during the early part of the twentieth century revealed significant artesian water reserves within fluvial sediments underlying impermeable lake bed silts and clays. The combination of multiple tectonic faults (most notably within the San Andreas Fault Zone in the southern portion of the Study Area) and an interlayered permeable and impermeable stratum led to the formation of springs, seeps, and marshes during prehistoric and historic periods (Sutton 1988b). Over-extraction of groundwater reserves during the modern era has led to a lowering of the Archaeological Research Design for the Antelope Valley Study Area 11 07A3822 Task Order 17 water table and, in the 1950s, noticeable ground subsidence, sinkholes, and desiccation cracks began appearing within the valley floor (Orme and Yuretich 2004). Many of the historic seeps and springs have dried within the last century. The San Andreas Rift Zone has permanent water sources because the fault traps water below the surface and forces it up along the fault into springs on the surface. Water from drainages in the mountains to the south is also trapped in the rift valley within ponds and lakes, such as Elizabeth Lake and Lake Hughes. Climate The Antelope Valley currently lies within an arid region with little natural perennial surface water. The valley is located in the rain shadow of the San Gabriel Mountains situated to the south and is secluded from marine air effects (Price et al. 2009). As a result of the variability of rainfall, surface hydrology is dominated by ephemeral washes, flowing only during storm events and remaining dry for most of the year. The hydrologic regime for the area follows the general Mediterranean climate, with cool, wet winters and warm, dry summers. Although the entire Antelope Valley is in the rain shadow of the San Gabriel Mountains, average rainfall within the Antelope Valley follows a decreasing gradient from west to east, creating a continuum from a more mesic environment in the west to a more xeric environment in the east. Winter storms move into the valley from the west and southwest, releasing rain as they pass over elevated terrain that borders the western part of the valley. Gorman, just to the northwest of Quail Lake at the west end of the valley, receives an annual average of 12 inches (305 mm) and foothill areas bordering the western valley receive 10 to 12 inches (254-305 mm) (Earle et al. 1997). By contrast, the valley east of Lancaster receives an average of 5 to 6 inches (127-152 mm). The valley floor between 9 and 27 miles (14.4-43.4 km) west of Lancaster averages 8 to 10 inches (203-254 mm). Temperatures in the Antelope Valley fluctuate widely throughout the year with hot summers and cold winters. At Edwards Air Force Base, on the eastern side of the Study Area, temperatures average between 96 and 98 degrees Fahrenheit (°F) in July and August with peak temperatures above 110 °F. Winters can be cold with nighttime temperatures regularly reaching below freezing with a minimum low temperature of 3 °F in January (Earle et al. 1997). Although the Antelope Valley is located in an arid region with limited rainfall, the Pleistocene/Holocene Lake beds in the eastern portion of the Valley (Rogers Lake, Rosamond Lake, and Buckhorn Lake) regularly fill with water during the winter months, forming ponds and, in wet years, shallow lakes that can last through spring (Earle et al. 1997). In major flood episodes water may flow across the valley floor in an eastward direction to Rosamond Lake. Archaeological Research Design for the Antelope Valley Study Area 12 07A3822 Task Order 17 Vegetation The majority of the vegetation in the Mojave Desert is composed of creosote bush (Larrea tridentate) and white bur-sage (Ambrosia dumosa). However, the vegetation does vary by elevation (Koehler et al. 2005). Low elevations are characterized by desert holly (Atriplex hymenelytra), bur-sage, and creosote, along with brittle bush (Encelia farinosa), pygmy-cedar (Peucephyllum schottii ), and cheesebush (Ambrosia salsola). In the next elevation range, from approximately 200 to 1,300 m AMSL, creosote bush dominates the landscape, with white bur-sage, ephedra (Ephedra spp.), brittlebush, wolfberry (Lycium spp.), Cooper’s golden bush (Ericameria cooperi ), ratany (Krameria spp.), and Mexican bladder sage (Scuttelaria [Salazaria] mexicana) as secondary components. The drier landscape (at an approximate elevation range of 1,300 to 1,700 m AMSL) has mesophytic upland desert shrubs such as desert almond (Prunus fasciculata), blackbrush (Coleogyne ramosissima), turpentine broom (Thamnosma montana), and Joshua tree (Yucca brevifolia). The landscapes at greater than 1,700 m AMSL support sparse stands of Utah juniper (Juniperus osteosperma) (Koehler et al. 2005). Today, the vegetation of Antelope Valley includes several plant communities which are distributed by elevation and soil chemistry. This discussion of the vegetation is synthesized from Hickman (1993), Holland (1986), Kremkau et al. (2013), Munz (1959, 1968), and Price et al. (2009). The major vegetation communities and their primary associated plants include: • Joshua tree woodland: characterized by Joshua trees with junipers (Juniperus spp.), creosote bush, buckwheat (Eriogonum spp.), pepper grass (Lepidium fremontii ), desert dandelion (Malacothrix glabrata), pincushion (Chaenactis sp.), and fiddleneck (Amsinckia tesselata), among others. • Creosote bush scrub: dominated by creosote bush and associated with white bur-sage, Anderson's boxthorn (Lycium andersonii ), brittlebush, prickly pear (Opuntia sp.), desert mallow (Sphaeralcea ambigua), winterfat (Krascheninnikovia lanata), cheesebush and Nevada ephedra (Ephedra nevadensis), among others. • Saltbush scrub: dominated by saltbush Atriplex spp., along with Anderson's boxthorn, rabbitthorn (Lycium pallidum), rubber rabbitbrush (Ericameria nauseosa), and antelope bush (Purshia tridentata), among others. • Pinyon juniper woodland: characterized by junipers, pinyon pines (Pinus monophylla and Pinus edulis), buckwheats, big sagebrush (Artemisia tridentata), and other Artemisia species, antelope brush, rabbitbrush (Ericameria spp.), mountain mahogany (Cercocarpus spp.), and snakeweed (Gutierrezia spp.), among others. The foothill slopes that fringe the Antelope Valley on the northwest and southwest are dotted by Joshua tree woodland community including Mojave yucca (Yucca schidigera), cacti, and grasses. Joshua trees are restricted to the desert edges, especially to the north and on the foothill slopes. It is important to note that although the Joshua tree is often considered to be a common vegetative Archaeological Research Design for the Antelope Valley Study Area 13 07A3822 Task Order 17 marker of the Mojave Desert, its range within the desert, especially in the lower elevations to the south is not precisely documented (Sutton 1996). Junipers (J. californica and to a lesser degree J. grandis) are present on the fringes of the valley along the slopes to the northwest and southwest. The valley floor has creosote bush scrub that includes creosote, white bur-sage (Ambrosia dumosa), brittle bush, rubber rabbitbrush, silver cholla (Opuntia enchinocarpa), beavertail cactus (Opuntia basilaris), cheesebush, and Mojave yucca. The dry lakebed of Pleistocene Lake Thompson is characterized by desert saltbush scrub vegetation which can tolerate high salt (halophytes) in the sediments and include saltbush (A. canescens), shadescale (A. confertifolia), and allscale (A. polycarpa). The alluvial fans and lower slopes are vegetated by big sagebrush, rubber rabbitbrush (Chrysothamnus spp.), tamarisk (Tamarix gallica), and mesquite (Prosopis spp.). Chia (Salvia columbariae), buckwheat, and ephedra (Ephedra spp.) also are present dotting the landscape. Nonnative plants such as giant reed (Arundo donax), tamarisk, California poppy (Eschscholzia californica), cheat grass (Bromus tectorum), filaree (Erodium spp.), and others are present in the valley. In recent history, domestic sheep grazing has had measurable effects on the vegetation in the Mojave Desert. Webb and Stielstra (1979) conducted a study on short-term effects of sheep grazing on the desert ecosystem which indicated that trampling resulted in severe compaction of soils, runoff increased in grazed areas, grasses generally increased while the above-ground biomass under creosote bush reduced significantly, as did the average cover of bur-sage. Today, Antelope Valley is dotted by agricultural fields and grazing areas, although the densities of these fields are not high. Fauna The list of the animals known to exist in the western Mojave Desert and their associated habitats or locales (Table 1) is based on the results of formal biological surveys conducted at Edwards Air Force Base (AFB) (Mitchell at al. 1993; TetraTech 2009; and additional information on shrimp in the western Mojave Desert [Brostoff et al. 2010]), as well as other informal reports for the region. Most animal occurrences are tied to habitat types, especially for small animals. Larger mammals and birds travel freely and may occur in multiple habitat types. Large mammals in the mountain areas include black bear, mountain lion, and mule deer. The nonnative Rocky Mountain Elk which were imported to the Tejon Ranch area from the Yellowstone area in historic times, but this species does not occur in any other part of the Antelope Valley. Black bears mountain lions, and mule deer are native animals. Some medium-sized animals inhabit both the mountain and desert areas, and include bobcat, coyote, gray fox, raccoon, and American badger. Desert kit fox, black-tailed jackrabbits, and desert cottontails mostly occur on the valley floor along with many types of rodents and reptiles. Black-tailed jackrabbits are known in all habitats on the valley floor and are known to be a primary food for large raptors, bobcat, and coyote. Raptors, including hawks and owls, are common predators of both rabbits and rodents. Numerous small birds and reptiles are present. In addition, playas inundated for days to weeks by seasonal rains contain several types of freshwater shrimp and water fleas.

In this section, discussion is focused on aspects of the prehistoric landscape that would have shaped and influenced Native American adaptations. Some of the plants that were important contributors to the plant diet, subsistence, and lifeways include bursage, creosote, saltbush, cacti, yucca, screwbean (Prosopis pubescens), mesquite (Prosopis glandulosa), Indian ricegrass (Stipa hymenoides), juniper, acorns (Quercus spp.), and piñon. The earliest vegetation record is from the Late Wisconsin glacial period during the late Pleistocene prior to human occupation of the Mojave Desert. At that time, the Mojave Desert had piñon-juniper woodland on the valley floor. At the beginning of the Holocene around 12,000 years ago the vegetation changed and the piñon-juniper woodland was replaced by desert shrubs (desert scrub and creosote scrub plant communities) on the desert floor (Koehler and Anderson 1998; Koehler et al. 2005; West et al. 2007). By around 8,300 years ago, Spaulding (1990) argues that juniper had disappeared from the lower slopes and was replaced by arid shrubs. As the desert grew warmer and drier, the vegetation shifted from sagebrush, rabbitbrush, and shadescale to arid species such as ephedra, matchweed, desert thorn, cacti, and Joshua tree, to very arid species such as white bursage, creosote, and other desert thermophiles (Spaulding 1990). It is important to caution that rarely are changes in vegetation communities synchronous because responses of individual plant taxa to changing climate are distinct and need not respond similarly in all soil types, and micro-niche climatic variability has to be taken into account when modeling vegetational change. In other words, the reconstructions done for the Central and Northern Mojave Desert areas may not be fully applicable to Antelope Valley. Creosote bush vegetation was most likely present during the Early and Middle Holocene (11,700 to 4200 cal BP) and was definitely established by the beginning of the Late Holocene (circa 4200 cal BP). West el al. (2007:32) state that by 5,000 years ago, the primary characteristics of the Mojave Desert vegetation as observed today were established, with modern associations developing over the next several thousand years. Similarly, Koehler and Anderson (1998:283) suggest that the “modern composition of dominant vegetation was completed about 4500 B.C.” Circa 4200 BP precipitation began to increase, resulting in greater resource productivity (Rhode 2001; Wigand and Rhode 2002). Bur-sage, creosote bush, saltbush, Joshua tree, and yucca were an established part of the vegetation by the end of the Pleistocene (11,700 years ago), but there may have been changes in their distribution and densities in response to micro-climatic changes in the Antelope Valley during the Medieval Climatic Anomaly (AD 300-700) and Little Ice Age (AD 1300-1870) events. Piñon was not a significant part of the vegetation on the desert floor from the earliest human occupation, but it was Archaeological Research Design for the Antelope Valley Study Area 21 07A3822 Task Order 17 likely present on the hills and mountain slopes to the northwest and southwest, at elevation ranges of approximately 3,000 to 9,000 feet AMSL (Clarke 1977; Minnich 1973). Similarly, oak trees and juniper were also present on the hills and mountain slopes above the desert margin; oaks were found up to 7,000 feet AMSL and juniper between 2,500 and 6,500 feet AMSL (Minnich 1973). Juniper occurs as part of the pinyon-juniper woodland community (between 3,000 and 5,000 feet AMSL), and Joshua tree-juniper woodland intermixed with saltbush scrub (between 2,500 feet AMSL and 5,000 feet AMSL) (Clarke 1977). The timing of the arrival of Indian ricegrass (Stipa hymenoides) in the Valley is not known, but the plant’s seeds were used for food during ethnohistoric times by Native Americans. Mesquite, and probably also screwbean, likely were established in the Antelope Valley by 4,200 years ago (Schroth 1987). Mesquite was used by Central Mojave Desert inhabitants by the Rose Spring Period (ca. AD 225 to AD 1100), based on macrobotanical data from the Afton Canyon site (CA-SBR-85). Schroth (1987) states that mesquite was used continuously from approximately 2000 BC by the Mojave Desert inhabitants. Ethnohistorically, the Antelope Valley area was used by the Tataviam, Kitanemuk, Serrano, and Kawaiisu groups. Documentation of plant use by these groups has been used as a model for prehistoric plant use. Two plants that occur in abundance in the Antelope Valley, bur-sage and creosote bush, have no uses as food, but they have been used for medicinal purposes. Different parts of saltbush), cacti, Joshua tree and yucca, screwbean, mesquite, Indian ricegrass, juniper, acorns, and piñon were all used as food (Bean 1972; Fowler 1986; Knack 1981; Kroeber 1925). Fowler (1986) identified several plant complexes for which specific procurement and processing techniques were developed by inhabitants of the Great Basin and Mojave Desert; two of these were plant complexes found on the valley floor: the agave/yucca/cactus complex and the mesquite/screwbean complex. The piñon-juniper complex and the acorn complex were found at higher elevations in the hills and mountains on the margins of the Antelope Valley. In addition to the members of these main plant groups, there were several plants that were of secondary importance to most of the Native American groups of the Valley. These plants include, but are not limited to, chia, blazing star (Mentzelia albicaulis), pigweed (Amaranthus spp.), buckwheat (Eriogonum spp.), desert dandelion (Malacothrix californica), tansy mustard (Descuriania pinnata), sea blight (Suaeda torreyana), desert onion (Allium fimbriatum), and desert lily (Hesperocallis undulata). During discussions with representatives of Native American communities in the Valley, as part of this study, researchers were provided with a list of traditional plants used by the Serrano ethnic group, which occupied the southern part of the Antelope Valley Study Area at the time of Spanish contact. These are listed in Table 2. Traditional uses of these plants among the neighboring Cahuilla ethnic groups have been well documented (Bean and Saubel 1972) and are provided in the third column of Table 2 for reference purposes only. Archaeological Research Design for the Antelope Valley Study Area 22 07A3822 Task Order 17 Fauna and Traditional Uses Based on archaeological collections, the mountainous fringe of the western Mojave Desert was home to black bear, bighorn sheep, deer, and chuckwalla. The valley floor was home to pronghorn, kit fox, jackrabbit, rabbit, squirrels, vole, rats, desert tortoise, iguana, and quail. Lynx, coyote, gray fox, and some others were found both in the mountains and on the valley floor. Temporally transitory lakes and ponds (including vernal pools) were home to ducks, geese, egret, heron, and fairy shrimp. Pronghorn antelope and jackrabbits are discussed in more detail below because of their potential to provide large amounts of meat as a result of communal hunting using drives and brush corrals. Animals that may have been used as resources for food, pelts, and feathers are listed in Table 3. Pronghorn antelope were present in the Antelope Valley grasslands in prehistoric and historic times. Large antelope populations were present in the valley well into the late 1800s, but in 1934 only four females were present in the valley according to a Fish and Game census. By 1940 pronghorn in the Antelope Valley were locally extirpated. Pronghorn are most active in the daytime. Their primary defense mechanisms were being part of a herd and fast locomotion. The animals are known to be very curious, and both prehistoric and modern hunters used a flag or pendant tied to vegetation to attract individual animals into range. Pronghorn were also hunted communally using drives. Table 2.

Resting spots tend not to be reused and are most often located in shade during hot months. In the Mojave Desert, resting spots are sometimes extended into shallow burrows when no other shade is available (Nagy et al. 1976). Jackrabbits evade their natural predators by having protective coloration, fast movement, and no scent. Reproduction can occur year round but tends to be most common in the first half of the year. Jackrabbits are known to travel to areas with more vegetation during winter months and travel distances of 5 km are common. Jackrabbits are also known to be attracted to seasonal water features in the Mojave Desert (Simes 2015). Carnivorous mammals, raptors, and colorful birds were likely hunted for pelts and feathers, but not used for food (Lightfoot and Parrish 2009:360-361). There is evidence for consumption of the remainder of the Archaeological Research Design for the Antelope Valley Study Area 26 07A3822 Task Order 17 animals listed in Table 2 and ethnographic evidence of use of resources like insects (Earle et al. 1997:49-50). Fauna with Supernatural Significance In addition to animals used in prehistoric times for food, pelts, and feathers, animals appear in native creation stories or have supernatural significance to this day. Understandably, Native American communities are reluctant to share their oral traditions/histories with non-community members, particularly for the purposes of publication. Thus, the information presented herein is based solely on published ethnographic works available for some of the Native American groups of the Mojave and Colorado Deserts. Among southern California Takic groups, living animals were believed to have been the descendants of animals created by the transformation of the First People by the Creator (Ramon and Elliot 2000:571-573). The interactions of the Creator with these First People, who combined human and animal characteristics at that time, comprise an important theme in sacred stories (Harrington 1986:III:101:73). Supernatural animals such as Coyote and Raven were described in sacred stories and referenced in sacred songs. The spirit helpers that were obtained at initiation among southern California Takic groups were often spirits in animal form. Various types of living animals were viewed as possessing special powers, such as understanding human speech or foreseeing the future (Ramon and Elliot 2000:218; Strong 1929:117). In addition, it was believed by the Serrano and other groups that some people formerly or presently had the supernatural power to transform themselves into animal form and back again (Ramon and Elliot 2000:294-295, 769-770, 793-794). Historically, information about living and supernatural animals has been provided by native people using native animal terms or glosses into Spanish or English folk terms for different animal species. The native ’taxonomy’ for animal species did not conform to categories of scientific classification. Thus, the correspondence of cultural or religious information about animals to specific species may be difficult to determine where closely related and phenotypically similar animal taxa occur in the southern California region. The religious and supernatural associations of specific animals are discussed below. Bears The bear appears among the First People and is a supernatural figure in sacred stories involving other such animals. At the time of the death of the Creator, he instructed Bear to gather wood and excavate a hole for his cremation (Strong 1929:140). In addition, it was believed that were-bears were present in the contemporary world because of the capacity of bear shamans to transform themselves into a bear form (Ramon and Elliot 2000:793-794). Living bears were also believed to have supernatural associations, for example a special group of white bears believed to live at a lake near the top of Mt. San Gorgonio (Gifford 1918:184). In addition, living bears were believed to have human emotions and unusual powers. Bears who lost siblings to human hunters would avenge Archaeological Research Design for the Antelope Valley Study Area 27 07A3822 Task Order 17 themselves, and it was said that it was dangerous for a person to speak ill of bears, for they would always hear this and avenge the insult (Benedict 1924:385; Strong 1929:116-117). It was also believed that native people could directly communicate with bears, including asking bears for permission to pass without harm when encountering them in the mountains (Strong 1929:117). Coyotes Coyote figured among the First People of creation time, stealing the Creator’s heart at his cremation. Coyote was a central figure in sacred stories as a muti-faceted character, exhibiting both good and bad behavior and character. Coyote was the representative animal of the Coyote moiety or ritual division among the Serrano and other Takic language groups. It was believed by the Serrano that ‘spirit’ Coyotes might be seen by people as an omen of misfortune (Ramon and Elliot 2000:192-193). Wolves Wolf was a supernatural being said to be the older brother of Coyote and exhibiting a more sober and reliable character (Gifford 1918:178; Zigmond 1980:229). Wildcats Wildcat was the supernatural representative animal of the wildcat moiety or ritual division among the Serrano and some other Takic groups, such as the desert, pass, and mountain divisions of the Cahuilla (Bean 1972:85). This appears to have been a bobcat such as Lynx rufus rather than a mountain lion (Puma concolor), because native consultants distinguished between wildcats (tukut) and mountain lions (wanac) (Gifford 1918:278; Ramon and Elliot 2000:343-344). Mountain Lions This animal is said by Gifford (1918:278) to have been linked to the Wildcat Moiety, along with wildcat (tukut), the principal moiety animal. Gifford referred to mountain lion (Puma concolor) as tukutcu, while Ramon called it wanac (Ramon and Elliot 2000:678). Benedict (1924:370) referred to the wildcat as tukut, and the mountain lion as wanac. Bighorn sheep These are associated with the supernatural migration song cycles, including migrations from the San Bernardino Mountains to the north down the length of the Mojave River and across the desert to the east. A traditional story about mountain lions hunting bighorn sheep in a celestial context was recalled by Ramon (Ramon and Elliot 2000:406-407, 677-678). Deer Deer figured among the First People of creation times. Ramon recounted a story about the moment of transformation of some First People into deer by the Creator (Ramon and Elliot 2000:571-573). Supernatural deer existed that could not be killed, according to Serrano belief (Bean and Smith 1978:573). Luiseño accounts describe a large, reddish magical deer that also could not be killed (Boscana 1933:132). Sacred songs with which the Serrano were familiar recounted places associated Archaeological Research Design for the Antelope Valley Study Area 28 07A3822 Task Order 17 with deer north of the San Bernardino Mountains (Ramon and Elliot 2000:201-202). Ramon recalled a story about a white deer seen as an ill omen (Ramon and Elliot 2000:663). Badgers Badger also figured among the First People of creation time and was present at the cremation of the Creator. It was said that the First People had surrounded the funeral pyre to prevent Coyote from entering the pyre and stealing the Creator’s heart. This stratagem failed, however, because due to Badger’s bowed legs, Coyote was able to push under him and get to his objective (Gifford 1918:184; Ramon and Elliot 2000:443-446,530-534) Rabbits Among the Kawaiisu, a sacred story recounted a supernatural Rabbit of creation times that routinely abused a rattlesnake that had not yet been endowed with fangs and venom - the snake begged the Creator for a means of defense to put the Rabbit in its place (Zigmond 1980:). A Cahuilla sacred story recounts Rabbit among the First People dodging arrows at the time that the Creator fomented war among them (Strong 1929:137). A Serrano sacred story recounts a celestial race between Coyote and Rabbit (Ramon and Elliot 2000:614-616). Rattlesnakes Supernatural rattlesnakes were important figures in native belief in southern California, and were frequently represented in pictographic rock art. For more westerly Takic language groups, Rattlesnake figured as one of the ‘familiars’ or manifestations of the deity Chinigchinich, and one of his ‘avengers’ (Boscana 1933:130-131). A Kawaiisu sacred story about Rattlesnake asking for fangs is referred to above. A similar story about the Creator giving fangs to Rattlesnake who was being abused was told by Cahuilla elders (Strong 1929:136). Frogs Frog was included among the First People. When they decided to kill the Creator, Frog was chosen to slowly poison him. The marks seen on a frog’s back today are described as having originated when the Creator probed at Frog (who he could not see) with a spear during the episodes of poisoning (Gifford 1918:184). Hummingbirds The Kitanemuk referred to the initial population of the world with people as having involved a female genitor at that time who gave birth to a supernatural Hummingbird (Blackburn and Bean 1978:568). A Cahuilla creation story recounts how the Creator had fomented war between the First People. Hummingbird, with a bow and a quiver on her back, could not be hit by her opponents because she was so small (Strong 1929). Archaeological Research Design for the Antelope Valley Study Area 29 07A3822 Task Order 17 Eagles Eagles were captured and raised to be used in the Eagle Killing Ceremony, an important ritual. Eagles also figured in the sacred origin stories of the Serrano and other Takic groups. A white eagle accompanied the creator being (Kukitat) on his southward migration toward Morongo (Gifford 1918:183). Among the Chumash, Eagle (Slo’ow) was one of the principal supernatural beings who controlled human fate. For Takic language groups, eagle feathers formed an important element in the Sacred Bundle that embodied the spiritual essence of a community. Hawks Hawks are referred to as First People and appear in sacred form in native sacred stories, such as a Kawaiisu tale about Owl, Snowbird, several Hawks, Eagle, Falcon, and Quail (Zigmond 1980:167-169). Owls The owl had supernatural connotations as an omen of bad fortune, as among the Kitanemuk (Blackburn and Bean 1978:568). A Kawaiisu sacred story recounts the interaction of Owl with various other sacred birds and other animals (Zigmond 1980:167-169). Ravens Raven was an important animal with supernatural connotations. For more westerly Takic language groups, Raven figured as one of the ‘familiars’ or manifestations of the deity Chinigchinich, and one of his ‘avengers’ (Boscana 1933:130-131). Among the Serrano, Crow was considered a relative of Wildcat (Gifford 1918:178). The Raven was considered a bird of omen, or a supernatural messenger (Boscana 1933:130). Lizards Lizard was found among the First People and played an important role in the efforts of the First People to kill their Creator, by observing the latter carefully at night while the other First People were asleep (Gifford 1918:199; Ramon and Elliot 2000:747-749). Such supernatural lizards were also described as having shamanic powers and the ability to perform ritual dances (Ramon and Elliot 2000:762-763). Antelopes Ramon recounted that Serrano sacred songs were sung that referred to antelope (Ramon and Elliot 2000:274-275). Foxes A Kawaiisu sacred story refers to Coyote attempting to imitate the actions of Fox, with disastrous results for Coyote (Zigmond 1980:103). Archaeological Research Design for the Antelope Valley Study Area 30 07A3822 Task Order 17 Butterflies and Moths The Luiseño Song of Temenganesh refers to butterflies with their cocoons having a form that recalls the Luiseño pohota or sacred enclosure (DuBois 1908). Ramon recalled that she was told that moths were spirit beings that should not be harmed (Ramon and Elliot 2000:863-864). Dragonflies The dragonfly (qrinyinyi') figures in a song of the Serrano, as sung today by Ernest Siva, relating to the dragonfly’s association with spirituality and good values. It is today a symbol for Serrano traditional culture and cultural values. Tortoises and Turtles A Kawaiisu sacred story recounts how Coyote and Turtle hunted deer, and Coyote used Turtle’s limited jumping ability to cheat him of the deer meat, with an angry Turtle later exacting revenge (Zigmond 1980:131). Squirrels and Chipmunks The squirrel and chipmunk were mentioned in Luiseño sacred songs, and it was recounted that chipmunk was one of the First People who helped to carry the log on which the Creator was laid during his cremation (DuBois 1908). Kangaroo Rats A Kawaiisu sacred story recounts how Coyote had an encounter with Kangaroo-rat, whom he proceeded to mock. He then attempted to imitate her actions in harvesting rice-grass seeds and ended up killing himself (Zigmond 1980:109). Quail Ramon recalled that several bird species were recalled as having spoken the Serrano language in respect to naming themselves, including the quail (Ramon and Elliot 2000:38). Zigmond (1980:185) reproduces a Kawaiisu sacred story about a supernatural Quail whose cradleboard-making provided a cultural charter for what kind of willow the Kawiisu should use to make cradleboards. Roadrunners An encounter with a roadrunner could be considered an ill omen among the Serrano (Ramon and Elliot 2000:854). Changes in Water Availability Through Time Late Pleistocene/Holocene Lake Stands Rosamond Lake, and its near neighbors within Edwards AFB — Rogers and Buckhorn Lakes — are Holocene relics of an earlier, much larger perennial body of water, Lake Thompson. From at least 30,860 BP, during the Wisconsin Glacial Stage, a lake as large as 950 square kilometers in area Archaeological Research Design for the Antelope Valley Study Area 31 07A3822 Task Order 17 and more than 80 meters deep filled the center of the Antelope Valley (Meyer and Bowers 2002; Orme 2008; Orme and Yuretich 2004; Rhode and Lancaster 1996). Rain and snowmelt from the San Gabriel Mountains to the south and southwest reached Lake Thompson mainly via Amargosa, Little Rock, and Big Rock Creeks, while Mojave, Oak, Cottonwood, and Los Alamos Creeks (Figure 3) brought runoff from the Tehachapi Mountains, located to the northwest. This high stand lasted for several thousand years, and continued, its depth and extent varying slightly, until around 17,000 BP. At times, the lake may have overflowed to the north into the Freemont Valley, its flood waters feeding Koehn Lake (Orme and Yuretich 2004). During the alternate climatic warming and cooling episodes that followed the Last Glacial Maximum and characterized the Pleistocene/Holocene Transition and the Holocene epoch, playas in the Mojave Desert became desiccated, then sometimes were refilled and stood for years, decades, or centuries as relatively shallow lakes. There is little evidence for the timing of the various infill events of the Lake Thompson playa, but shoreline and wave-deposited sediments around Rosamond Lake indicate that there may have been infill events and shallow lake stands around 12,600 BP and around 6830 BP (Orme 2008; Orme and Yuretich 2004). As temperatures warmed in the Holocene, Lake Thompson eventually broke up into Rogers Lake, Rosamond Lake, and Buckhorn Lake (Figure 3) around 8,000 years ago (Thompson 1929). During the late Holocene, periodic short-duration partial to full inundations of these lakebeds occurred during exceptionally wet winters. Today, most of the water comes from direct rainfall and local runoff, but occasionally, as in the 1982-1983 El Niño episode, stream flow from the mountains is sufficient to reach the playas (Lee 1997; Meyer and Bowers 2002; Orme and Yuretich 2004). During rainfall events small playa basins and stable dunes along the margins of Rosamond and Rogers Dry Lakes provided natural catch basins for water runoff and rainfall from areas throughout the Antelope Valley. These small basins or ponds were able to retain water for relatively long periods of time, attracting birds and sustaining plant growth (Norwood 1989).

Antelope Valley Hydrological and Topographical Features 2015-075.017 Antelope Valley Research Design Water Seeps and Springs The Antelope Valley is an enclosed drainage basin. Prior to the arrival of Europeans, the unique topography and the high percolation-ability of the sediments resulted in a high water table within the valley floor (Orme 2008). The combination of the high water table and multiple small faults within the valley interior and along the San Andreas Rift Zone resulted in the Antelope Valley containing numerous springs, marshes, and seeps during the prehistoric period (Sutton 1988b). Notable springs within the valley that were active during the pre-contact period include Bean Springs, Willow Springs, Lovejoy Springs, and Buckhorn Springs (Earle et al. 1997) (see Figure 3). There was a system of sag ponds in the area now occupied by Quail Lake (a modern man-made reservoir) at the west end of the Antelope Valley. In addition, numerous springs and seeps were located within the San Andreas Rift Zone including a spring and potential small lakebed at the location of modern Lake Elizabeth. Thus, despite the arid climatic conditions, both perennial and, depending on the climatic fluctuations, seasonal water sources were likely present throughout the Antelope Valley during the prehistoric period. Lithic Sources A variety of both local and imported lithic material was available to prehistoric inhabitants of the Antelope Valley. Local lithic material, including rhyolite, cryptocrystalline silicate (CCS; jasper, chalcedony, and chert), quartz, steatite, and basalt was primarily quarried from the Tertiary-age volcanic buttes and hills located throughout the Antelope Valley and from the San Andreas Rift Zone. Notable lithic sources within the Antelope Valley include rhyolite outcrops at Fairmont Butte and the Rosamond Hills, CCS sources in the Rosamond Hills and Kramer Hills to the east of the Study Area, and steatite outcrops in the Sierra Pelona within the San Andreas Rift Zone (Earle et al. 1997; Sutton 1993). In addition to these well-studied sources, other buttes and hills within the valley, including Little Buttes, Soledad Mountain, and the Bissell Hills contain rhyolite and/or CCS materials (Dibblee 1967). No attempts have been made to identify all the available lithic sources in the region. However, the Antelope Valley and adjacent areas likely contained numerous CCS sources (Sutton 1988b). Quartz and basalt are prevalent both within the valley and in the surrounding mountains. Little information is known about the specific sources for these materials. In addition to locally available lithic materials, imported materials are prevalent throughout sites in the Antelope Valley Study Area. Most notably, obsidian from the Coso Mountains to the north is present in the archaeological record throughout the Valley (Sutton 1991). In addition to obsidian, fused shale from Ventura County has been identified at sites within the Antelope Valley (Earle et al. 1997). Lithic sources are discussed in more detail in the Theme: Lithic Material Sources section. Archaeological Research Design for the Antelope Valley Study Area 34 07A3822 Task Order 17 CULTURAL SETTING Archaeological Research Design for the Antelope Valley Study Area 35 07A3822 Task Order 17 Chronology The cultural chronology used for the Antelope Valley is based on a chronology for the Mojave Desert widely used in recent decades (Earle et al. 1997; Price 2009; Warren 1984), albeit with some variations in starting and ending dates for specific periods. The temporal units used by Sutton et al. (2007) for the Mojave Desert were termed complexes because it was thought each complex represented a specific cultural adaptation or even a cultural group. However, cultural characteristics may vary within a temporal unit, both temporally and spatially. In the greater Antelope Valley region, the juxtaposition of different foothill and desert-based adaptive systems and, apparently, of different cultural groups, makes the identification of a single complex as being characteristic of a temporal unit problematic. The temporal units used here are periods that are based on shifts in projectile point types (for illustrations of the projectile point types characteristic of the Antelope Vally, see Sutton [2018:36] and Sutton et al. [2007:234]). Such projectile point changes are used to mark temporal units, since this class of artifacts is the only one that can provide temporal markers for each cultural period from the Pleistocene to Spanish contact (Sutton 2017:4). The date ranges for the cultural periods are adapted from Sutton (2016:267-268). Sutton (2016) does not indicate whether the date ranges are based on calibrated dates. The Antelope Valley chronology is shown in Table 4 and each period is discussed below. Table 4. Antelope Valley Chronology Geological Era Late Pleistocene/Early Holocene 25,000-11,700 cal BP Early and Middle Holocene (11,700-4200 cal BP) Late Holocene (4200-0 cal BP) Period Clovis Period Years 12,000 to 9500 BC Lake Mojave Period Pinto Period Gypsum Period Rose Spring Period Late Prehistoric Period Mission Period 9500 to 7000 BC 8250 to 2500 BC 2500 BC to AD 225 AD 225 to 1100 AD 1100 to AD 1769 AD 1769 to AD 1835 Although there is archaeological evidence for human occupation before 12,000 BC elsewhere in the Americas, no cultural material dating to the time before the Clovis Period has been found in the Mojave Desert to date. Archaeological Research Design for the Antelope Valley Study Area 36 07A3822 Task Order 17 Late Pleistocene/ Early Holocene (25,000-11,700 cal BP) Clovis Period (12,000 to 9500 BC) The Clovis Period was an era of environmental transition between the late Pleistocene and early Holocene. The Clovis Period within the Mojave Desert is represented by fluted projectile points that were used by big game hunters. Fluted projectile points, including both Clovis points and Great Basin Corner-Notched points, were hafted to the end of a throwing spear. Fluted points have been discovered along the shores of former pluvial lakes at China Lake Naval Weapons Station (north of Antelope Valley) and Edwards Air Force Base (within the northeastern part of Antelope Valley). There are two sites at Lake China with Clovis and Lake Mojave points (a later point type; see below). Thus, it is not known if other artifacts at these two particular sites are associated with Clovis Period or Lake Mojave Period, or both. All other Clovis points in the Mojave Desert occur as isolated surface finds (Sutton 2018). It is thought that populations during this time period in the region consisted of small bands of hunters who followed big game herds. Early and Middle Holocene (11,700-4200 cal BP) The people who occupied the Mojave Desert during the Early and Middle Holocene are posited to be descendants of the megafauna hunter populations who successfully adapted to warming and drying conditions after the ice age ended. During the Early Holocene (11,700-8200 cal BP), the focus was on hunting artiodactyls around the remnant lakes. During the warm arid conditions of the Middle Holocene (8200-4200 cal BP) these groups became more generalized foragers who hunted and trapped large, medium, and small mammals and added plant foods to the diet. Lake Mojave Period (9500 to 7000 BC) During the Early Holocene the climate became warmer and drier resulting in a changing distribution of faunal communities, including a decrease in large game and an increase in the availability of small game such as rabbits and rodents (Sutton 2018). However, there were still remnant pluvial lakes at this time, and Lake Mojave Period sites are typically (but not exclusively) found around the margins of ancient lakes. The Lake Mojave tool assemblages include Great Basin Stemmed series projectile points including Lake Mojave and Silver Lake points. The shift from fluted points to stemmed points may indicate a shift from hunting megafauna to hunting artiodactyls (deer and mountain sheep). Sutton (2018) says that the fluted points were used on thrusting spears in an intercept hunting strategy, while the stemmed points of the Lake Mojave period were likely used on smaller spears launched with a spear-thrower (atlatl). Other flaked stone tools include crescents (eccentrics), leafshaped bifaces (cutting and piercing tools), formed unifaces including large domed scrapers and small beaked engravers, and cores from which flakes could be removed as needed. The cores were also used as tools (Sutton 2018). Ground stone implements occur in small numbers during this time (Warren 2002) and indicate the addition of hard seeds in the diet. It appears that Lake Mojave Archaeological Research Design for the Antelope Valley Study Area 37 07A3822 Task Order 17 groups gradually adapted to an increasingly warmer and drier environment resulting in shifts in technology and subsistence, with exploitation of additional ecozones. Pinto Period (8250 to 2500 BC) The Pinto Period overlaps in time with the Lake Mojave Period because both Great Basin Stemmed points and Pinto points were used during the period from 8250 to 7000 BC. The Pinto Period was a time of increasing aridity which culminated in the Mid-Holocene Warm Period, circa 5500-2500 BC. This warm period is characterized by the disappearance of lakes, followed by a great reduction in streams and springs. By the end of the Pinto Period, water could be obtained only at a small number of seasonal springs. The desert vegetation community that was similar to that of today developed during this period. Pinto period sites are usually found in open settings, in relatively well-watered locales representing isolated oases of high productivity with fossil stream channels and springs. Increasing amounts of ground stone tools suggest increasing use of small seeds. Artiodactyl hunting continued, but increasing aridity reduced the number of deer available. Greater numbers of small animals such as rabbit, rodent, reptile, and fresh water mussel resources were exploited compared to previous periods. The artifact assemblage is similar to the Lake Mojave assemblage. Pinto projectile points replaced Lake Mojave points and Silver Lake points, and the crescents and engravers characteristic of the Lake Mojave Period were no longer used. Drills were added to the assemblage and the number of ground stone tools increased (Warren 2002). Warren (2002:139) sees the shift in projectile point types and the increasing use of plant foods during the Pinto Complex as resulting from decreasing numbers of artiodactyls (deer and mountain sheep) during this warm, dry period. In order to more efficiently take more of the diminishing numbers of artiodactyls, Pinto points were used because the shouldered Pinto points stayed inside the animal after it was shot (Warren 2010). Late Holocene (4200-0 cal BP) At the beginning of the Late Holocene after about 4200 BP (circa 2200 BC) annual rainfall increased and areas that could support significant amounts of food resources expanded. During the Late Holocene there is an increase in population, along with what appears to be increasing sedentism and resource intensification in and around the Antelope Valley. Three periods were defined within the Late Holocene in the Mojave Desert: the Gypsum Period (ca. 2500 BC to AD 225), the Rose Spring Period (roughly equivalent to Warren’s Saratoga Springs Period) (ca. AD 225 to 1100), and the Late Prehistoric Period (ca. AD 1100 to AD 1769) (Sutton 2007 et al.; Sutton 2016; Warren 1984). Each period is characterized by specific projectile point types. Gypsum Period (ca. 2500 BC to AD 225) During the Gypsum Period the artifact assemblage included Elko and Gypsum dart points and bifaces. Ground stone milling tools become relatively commonplace. The subsistence pattern, based on material found in temporary camps in the desert, included generalized hunting activities (large, medium, and small mammals, and desert tortoise), and seed processing, indicated by more Archaeological Research Design for the Antelope Valley Study Area 38 07A3822 Task Order 17 numerous milling stones than in previous periods. Mesquite, located in high water table areas, may have been an important food resource during Gypsum times. Quartz crystals, paint, and rock art indicate ritual activities (Sutton 2017:9). A bone awl recovered at Barrel Springs (CA-LAN-82) suggests the manufacture of basketry by this time. There was a large residential site at the Fairmont Butte rhyolite source during this period and the CA-KER-303 site complex on the northwest side of the Antelope Valley, a permanent village in later periods, was occupied beginning in Gypsum Period times. These developments have suggested an increase in population in the Antelope Valley in Gypsum Period times. Rose Spring Period (ca. AD 225 to 1100) The Rose Spring Period is also known as the Saratoga Spring Period. The bow and arrow were introduced in the Antelope Valley at the beginning of the Rose Spring Period circa AD 225. Rose Spring and Eastgate arrow points were used, along with Cottonwood Triangular points beginning around AD 900. Other artifacts include stone knives and drills, bone awls, and ground stone tools. Manufacture of chlorite schist beads and steatite artifacts was being carried out in the southern Antelope Valley by this time. Late Prehistoric Period (ca. AD 1100 to AD 1769) The archaeological material from the Late Prehistoric Period resulted from the activities of the ancestors of the ethnographic groups around the edges of Antelope Valley region including the Kitanemuk, Tataviam, Serrano, and Kawaiisu. Desert Side-Notched and Cottonwood Triangular arrow points were used during the Late Prehistoric Period. The rest of the Rose Spring artifact assemblage continued into the Late Prehistoric period with the addition of pottery. Bedrock mortars occur in high frequencies in the residential bases and villages along the desert margin. Some desert floor sites, such as CA-LAN-298, have both bedrock mortars and portable mortars and pestles. Mission Period (AD 1769 to AD 1835) The Mission Period begins with the Portola Expedition in AD 1769 which established the first permanent Spanish presence in California. Franciscan friars established missions at San Gabriel (AD 1771) and San Fernando (AD 1797) (Castillo 1978). The first written historical information about Native Americans in the Antelope Valley region dates from the 1770s, during the Mission Period. Ethnohistorical documentation from this period includes mission records and the accounts of Spanish friars and soldiers (Bolton 1935:6-7,12-13; Cook 1960:245-248, 256-257; Coues 1900:I:267270; Huntington Library 2006). Although California became part of Mexico after Mexican independence in 1821, the missions secularized and closed until circa 1835. Other Temporal Units Sutton (2018) recently proposed new temporal units consisting of patterns and phases with dating based on BP, rather than BC, for the Late Pleistocene through the Middle Holocene. In Sutton’s new scheme, the Clovis Period is now the Lakebed Pattern which is divided into Lakebed I (11,600 to Archaeological Research Design for the Antelope Valley Study Area 39 07A3822 Task Order 17 11,000 BP) Phase and Lakebed II (11,000 to 10,200 BP) Phase. The Lake Mojave Period is the Lake Mojave Pattern with Lake Mojave I (10,200 to 9300 BP) and Lake Mojave II (9300 to 8500 BP) Phases. The Pinto Period is the Pinto Pattern with Pinto I (8500 to 7500 BP), Pinto II (7500 to 5000 BP), and Pinto III (5000 to 4000 BP) Phases. Sutton (2018) does not indicate whether the date ranges are based on calibrated dates. Note that in this new chronology the Lake Mojave Pattern does not overlap in time with the Pinto Pattern. Sutton’s new chronology is not used in this research design since it has not yet been evaluated by other archaeologists who specialize in the Late Pleistocene and Early/Middle Holocene of the Mojave Desert. Archaeological Research Design for the Antelope Valley Study Area 40 07A3822 Task Order 17 Previous Investigations Overview of Previous Investigations and Major Sites in the Antelope Valley Historically, few archaeological studies were conducted in the Antelope Valley compared to the central and eastern areas of the Mojave Desert. Early studies in the 1920s and 1930s were conducted by a mix of amateur collectors and professional researchers. Although many private and public museum collections date to this era, little documentation is available for much of this early work. Collections of artifacts from Antelope Valley archaeological sites can be found at the Fowler Museum at University of California, Los Angeles (UCLA), the Antelope Valley Indian Museum, Antelope Valley College, the Kern County Museum, and Edwards AFB curation facilities. Professional studies of the Antelope Valley increased in the early 1960s with the work of William Glennan. William Glennan excavated multiple sites in the Antelope Valley including the Fairmont Butte Site and the Sweetser Site (Stickel and Weinman-Roberts 1979). Glennon’s work was followed, in the late 1960s through the 1980s, by an increased number of studies by local universities and military installations. Based on early reports housed at the South Central Information Center, in the 1970s, Edwards Air Force Base began their cultural resources program and several institutions including Antelope Valley College, California State University Bakersfield, and UCLA conducted much of the work in the area during this time. Two researchers, Dr. Roger Robinson at Antelope Valley College and Dr. Mark Sutton at CSU-Bakersfield led the majority of the studies within the Antelope Valley during this period. In the late 1980s and 1990s, research in the Antelope Valley moved away from the universities and transitioned to being conducted by cultural resources management firms for specific development projects. As part of the current study, a records search was performed at both the South Central Coastal Information Center and Southern San Joaquin Valley Information Center for the entire Antelope Valley Study Area. As a result of these records searches, 85 reports were identified that included substantial site information, subsurface testing and data recovery results, or presented overview data for the Study Area (see Attachment A). Of these 85 reports, approximately 37% dealt with investigations within Edwards Air Force Base, and another 22% were related to investigations within or near the town of Rosamond (just west of Edwards Air Force Base). The western, central, northern, and southern portions of the Study Area are more sporadically represented in the literature. Major Sites and Studies within the Study Area Based on a review of the reports from the information centers, lithic scatters and temporary campsites make up the most commonly recorded sites in the Study Area. Larger, more intensively used sites containing deep midden deposits, rock art, burials, and evidence of continuous or Archaeological Research Design for the Antelope Valley Study Area 41 07A3822 Task Order 17 frequent seasonal occupation are present within the Study Area, but are less frequent. These larger sites tend to be located near springs, creeks, or buttes containing lithic material sources. A brief discussion of selected studies (Table 5) and sites (Table 6) within the Study Area is presented below; locations of sites discussed are shown in Figure 4. The following discussion provides the results of selected major projects conducted in three different parts of the Study Area (Antelope Valley, Tehachapi Mountains and Foothills, and San Andreas Rift Zone and San Gabriel Mountains) that provide insight on prehistoric and historic period human adaptations and occupations.

Archaeology on Edwards Air Force Base was spearheaded by Mark Sutton in the 1970s and continued by Richard Norwood and his successors to this day. More studies have been conducted on the Base than in any other portion of the Antelope Valley. A summary of all recorded sites on Edwards Air Force Base was prepared by Computer Sciences Corporation in 1997 (Earle et al. 1997) that documented the site work done on the Base to that point. As of that time, 1,084 prehistoric-age sites had been recorded on Base property and 126 of these had been subject to subsurface testing. Although new sites have been subsequently identified on the Base, Earle et al. (1997) provide a good basis for establishing the types of sites present on the Base property. Four hundred and sixty-five sites (42%) are described as lithic scatters or flaking stations, and 416 (38%) of recorded sites are considered to represent temporary camps. These two site types make up the majority (80%) of the sites recorded within the Base boundaries. Other site types present, but not as prevalent, include hearth and roasting features (9%), milling stations (5%), lithic quarry sites (1%), rock shelters (less than 1%), residential bases or villages (less than 1%), cremations (less than 1%), rock alignments (less than 1%), pictographs (less than 1%), faunal/animal bone scatters (less than 1%), and isolated finds (less than 1%) (Earle et al. 1997). The numbers and proportions of each site type on Edwards Air Force Base are based mostly on surface data. However, identification of site type based on surface characteristics is likely fairly accurate in a desert environment where vegetation is minimal and ground visibility is generally good. The full distribution of subsurface resources across the Antelope Valley Study Area is unknown and the available information is based solely on the small percentage of sites that have been tested or excavated. The potential for an area to contain buried resources depends heavily on a variety of factors including landform, surface stability, paleo environment, and the intensity and length of Archaeological Research Design for the Antelope Valley Study Area 45 07A3822 Task Order 17 human occupation. To date, a full survey of the Antelope Valley for buried resources has not been conducted. A brief description of selected sites on the Base is provided below. CA-LAN-863 is a large 3,000,000-square meter residential base with multiple loci with deposits to a depth of 155 centimeters below surface. Artifacts recovered include approximately 2,000 pieces of debitage, lithic tools, ground stone, schist fragments, shell beads, fire affected rock, charcoal, over 3,000 faunal/animal bone fragments, shell fragments, and egg shells. Obsidian hydration analysis and shell bead analysis have produced dates of 4200 BP, 1100 BP, 500 BP, and 200 BP (Earle et al. 1997). CA-KER-526 is a large (35,727-square meter) residential base with a substantial subsurface component reaching a depth of 190 centimeters below surface. The site contains two discrete occupation units consisting of the main site deposit and a blown-out artifact concentration. Both occupation units were dated to the Gypsum Period using obsidian hydration and radiometric data. Artifacts recorded include approximately 10,000 flakes, lithic tools, ground stone, shell beads, shell fragments, and over 14,000 faunal bone fragments (Earle et al. 1997). CA-LAN-828/H is a large temporary camp and historic-period home site. The prehistoric portion includes debitage, lithic tools, shell beads, shell fragments, ground stone, fire-affected rock, and an anthropomorphic figurine. The site was dated to approximately 2200 BP to 1400 BP (Rose Spring Period) (Earle et al. 1997). CA-KER-3033 is a 1,000-square meter temporary camp containing a subsurface deposit down to 110 centimeters. The site contains a hearth, more than 6,000 pieces of debitage, rhyolite tools, cores, ground stone, shell beads, charcoal, and small mammal bones. Radiocarbon testing from collected charcoal samples yielded dates between 2560 and 2240 BP (Earle et al. 1997). CA-LAN-716 is a large low density lithic scatter that measures 200,000-square meters. Subsurface testing indicated that the site is approximately 10 centimeters deep. Artifacts recovered include 44 flakes, 1 scraper, and 15 faunal/animal bone fragments (Earle et al. 1997). CA-KER-2489 is a 1,200-square meter rhyolite quarry and rock shelter. The site has a maximum depth of 30 centimeters, and contains 175 pieces of rhyolite debitage, three debitage pieces of other lithic materials, three bedrock mortars, and four rodent and lagomorph bones (Earle et al. 1997). In addition to the sites listed above, in 2013, a survey of 3,140 acres in the northwestern part of the Base for the Oro Verde Solar Facility Project recorded only 49 lithic scatters, 78 temporary camps, and 1 possible hearth/roasting pit in this large area (Cunningham et al. 2013). This represents limited use of this area by ancestors of the Kawaiisu. Sweetser Site (CA-KER-302). CA-KER-302 is a prehistoric occupation site located in the Hidden Valley area of the Rosamond Hills. This site was originally studied by William Glennan, who conducted surface artifact collections of the site in 1964 and 1965. He described the site as a semi-permanent Archaeological Research Design for the Antelope Valley Study Area 46 07A3822 Task Order 17 camp encompassing 1-acre and containing lithic tools, debitage, ground stone, bedrock mortars, and petroglyphs (Glennan 1971). This site, along with the Fairmont Butte Site described below, formed the basis of Glennon’s rhyolite tradition theory, which postulated that there was an early cultural tradition in the Antelope Valley that utilized local rhyolite almost exclusively for stone tool manufacture (Sutton 1987). Glennan dated the site to 4000 to 6000 BP, although no absolute dating methods were used, and his date estimations were based primarily on comparisons of tool types. In 1991, the site was resurveyed by Robert Yohe who noted that the site is considerably larger than described by Glennan. In 1994, James Brock conducted test excavations of the southern portion of the site (Brock 1994). As a result, significant subsurface deposits were identified as well as a buried occupation level and a large lithic scatter associated with quarrying and lithic reduction. The Sweetser site is often used as the type site for the Pinto Period, although no absolute dates have been established for the site and Brock (1994) has doubts that the site dates to that period. Willow Springs Site (CA-KER-129). CA-KER-129 was recorded by Price in 1954. This site was noted as containing multiple temporary camps, milling features, a complex of 49 rock cairns, rock art, and midden near the springs. It appears to have been occupied in the Late Holocene. Although Sutton suggests CA-KER-129 was a Kitanemuk village (Sutton 1988a, 2016), the site may have been a camp or seasonal residential base re-occupied from year to year by the ancestors of both the Kitanemuk and Serrano. Bean Spring Site (CA-KER-2821/H). CA-KER-2821/H is a large prehistoric occupation site and historicage ranch complex located northwest of Willow Springs at Bean Spring. The site includes 20 separate loci and covers an area of 371 acres. The site is centered on Bean Springs and includes midden, shell beads, ground stone, lithic tools, debitage, and hearth features. In 2009, Pacific Legacy conducted subsurface testing on a portion of the site (Way et al. 2009). The excavations identified a subsurface deposit down to a depth of at least 60 centimeters below surface. Atomic mass spectrometry radiocarbon dates from shell beads from the site produced dates of 9020-9430 and 8020 radiocarbon years BP, providing dates from the early Lake Mojave Period. Additional radiocarbon dates from hearth features indicate that this site was occupied either continuously or regularly through the Late Prehistoric Period. Lithic tools noted include Pinto, Elko, and Cottonwood series projectile points and a re-sharpened Great Basin Stemmed series point. This site has evidence of an extensive trade network to acquire lithic materials from the San Joaquin Valley, Fairmont Butte, Rosamond Hills, Brown Butte, Gem Hill, the Coso Mountain Range, and Grimes Canyon in Ventura County (Way et al. 2009). The site may have been a camp or seasonal residential base re-occupied from year to year. Fairmont Butte Site (CA-LAN-1789/H). CA-LAN-1789/H is a collection of separate loci located in and around Fairmont Butte in the southern central Antelope Valley. The loci within the Fairmont Butte Site were originally recorded as 12 separate sites (CA-LAN-296, -298, -677, -679, -680, -681, -682H, 683, -684, -685, -686, and -898), but were later combined into one large site CA-LAN-1789/H in 1989 (Love et al. 1989). Fairmont Butte is a low-lying hill in the central-southern portion of the Antelope Valley that contains tool-quality rhyolite. Fairmont Butte rhyolite was extensively quarried in Archaeological Research Design for the Antelope Valley Study Area 47 07A3822 Task Order 17 prehistoric times and traded over large portions of the Antelope Valley. The Fairmont Butte site contains rhyolite quarry sites, lithic scatters, over 500 bedrock mortars, and a large midden site (CALAN-298). Several Fairmont Butte sites were originally excavated by Glennan in 1970 who noted that the majority of the lithic material identified was made of rhyolite. In the 1970s, additional surveys and subsurface investigations, notably by Antelope Valley College, added additional loci to the site and extensive excavations conducted within the midden portion of the site. In the late 1970s, excavations at Fairmont Butte by Mark Sutton found two buried occupation horizons that continued to a depth of 2 meters (Sutton 1982a). The uppermost horizon contained a dense deposit of varied Late Prehistoric Period artifacts. Below this, Sutton found a deposit of exclusively rhyolitic artifacts and no late materials. The midden deposit at CA-LAN-298 is about two meters deep and is associated with bedrock mortars and rock art (Sutton 1982a). Shell and stone beads and three glass trade beads were excavated from CA-LAN-298 in the 1990s (Sutton 1988b). Occupation at CA-LAN-298 appears to have begun during the Pinto Period (prior to 2,000 BC) and continued through the Late Prehistoric Period (A.D. 1200 - contact) (Sutton 1988b:75). A larger midden area (over 150 meters long) is known in the southern part of Fairmont Butte, but has never been excavated (no site number assigned). Over 530 bedrock mortars are known in the entire Fairmont Butte complex. These data suggest there was a village at Fairmont Butte, although no cemetery has been found. Lovejoy Springs Site (CA-LAN-192). CA-LAN-192 is a large prehistoric occupation site centered on Lovejoy Springs near Lovejoy Buttes about 15 km north of the mouth of Big Rock Canyon near Lake Los Angeles. The site contained deep midden deposits, debitage, tools, ground stone, both native and Southwestern ceramics, and nine human burials containing several thousand shell beads. Although heavily collected over the last century, the site measures at least 500 meters by 1,000 meters (500,000 square meters) in size (Price et al. 2009). Both formal and informal studies and artifact collections have been carried out on the site in the 1920s, 1954, 1968, 1989, 1990, 1994, 1996, 2004, and 2005. Older informal collections and the construction of Lake Los Angeles led to the destruction of a large portion of the site. In 2005, Applied Earthworks, Inc. was contracted to conduct phased studies of the site, synthesize previous studies, and analyze artifacts housed in various local repositories (Price et al. 2009). The site has an extensive Gypsum Period component with large quantities of manos and metates and a cemetery with multiple individuals and thousands of Olivella beads. A child burial had a double loop necklace with 2,135 Olivella saddle beads or tiny disc beads. Radiocarbon dating from the child burial yielded a date of circa 2700 BP (700 BC in the late Gypsum Period). There is a Rose Spring component at the site, indicated by one radiocarbon date and obsidian hydration measurements, and a Late Prehistoric component with Desert Brownware ceramics and a radiocarbon date of 350 B.P. (Price et al. 2009). Although most of the cultural material at the site has not been assigned to a particular time period, it is likely that this was a permanently occupied village site in Late Prehistoric times and may have been so since Gypsum times. State Route 138 Corridor Studies. In 2014 and 2015, ECORP Consulting, Inc. surveyed a 36-mile long section of State Route 138 between Interstate 5 and State Route 14 in the western and central Antelope Valley, as part of the SR-138 Northwest Corridor Improvement Project. As a result of this Archaeological Research Design for the Antelope Valley Study Area 48 07A3822 Task Order 17 study, nine prehistoric-age sites (lithic scatters and temporary camps) were recorded and tested. A summary of the results of testing for the four largest sites is provided below (see Mason and Blumel 2015). A lithics analysis for these four sites is provided in Attachment B. CA-LAN-4640 is as a large temporary camp located on top of a steep hill south of Quail Lake near the western boundary of the Antelope Valley. This site is located within the San Andreas Fault Zone, west of the Rift Zone, and its northern boundary appears to be truncated by the fault. Twenty-eight shovel test pits (STPs) and two test units were placed within the site boundary. Artifacts were found to a depth of one meter with a total of 165 artifacts collected from the site (23 from the surface collection, 81 from the STPs, and 61 from the test units). The site contained primarily lithic artifacts along with some ground stone, fire-affected rock, faunal bone, and several small shell fragments. An analysis of the lithic artifacts indicated that a total of 35.2% of the assemblage are shatter, 62.4% are flakes, 1.2% are cores, and 1.2% are lithic tools. The lithic assemblage recovered indicates diversity in raw material type but limited to debitage rather than cores or tools. A wide range of raw materials including CCS, fine grained volcanic material, obsidian, fused shale, and quartzite were used to produce or maintain biface cores or tools at the site. Flakes were also produced at the site, mostly from CCS and obsidian. Pressure flaking was minimal and restricted to CCS and obsidian only. The lack of diagnostic artifacts or chronometric dates prohibits assignment of chronological period. The recovery of fused shale from the site has the potential to address research questions involving the use of this material in the Antelope Valley. CA-LAN-4632 is a lithic scatter located on a low hill south of State Route 138 near the Community of Neenach. It was subjected to surface collection and six STP units. The greatest recorded depth for any artifact is 30-35 cm. A total of 53 artifacts were collected from the site, with 48 found on the surface, and five from the STPs. A total of 28.3% of the assemblage is shatter, 56.6% are flakes, 11.3% are cores, 1.9% are lithic tools, and there is one unmodified cobble of vitreous basalt that was collected as a possible artifact (most likely not an artifact). The lithic assemblage is composed of three different material types. The most common material is basalt, with 67.9% artifacts. Vesicular basalt makes up 28.3% of the total assemblage. Chalcedony is relatively uncommon, comprising only 3.8% of the assemblage. Although the assemblage is small and has little diversity, it is likely that the primary activity at the site was the initial reduction of local basalt and vesicular cobbles into cores, and the production of some flakes suitable for use as tools, though at least some chalcedony flake production was also conducted. There is very limited evidence of other activities based on this assemblage, consisting solely of an expedient-use modified basalt flakes. It is not possible to assign a chronological period for this site based on the lithic assemblage. Although CA-LAN-4632 has limited information, it is nonetheless important as one possible source for basalt tools and debitage found at other sites in the Antelope Valley. CA-LAN-3723 is a large temporary campsite located approximately one mile northwest of the Fairmont Butte rhyolite source. What is currently the totality of site P19-003723 was originally recorded as two separate resources. The portion of the site south of SR-138 was recorded in 2007 as P19-003723 and the portion of the site north of SR-138 was recorded in 2014 and designated as Archaeological Research Design for the Antelope Valley Study Area 49 07A3822 Task Order 17 P19-004621. At a later time, the two sites were combined. The site was evidently subject to historic agricultural activity which resulted in the mixing of the top 20 to 30 cm of soil, and likely resulted in damage to some of the artifacts. The site is also close to Highway 138 and may have been subjected to considerable artifact collection. As originally recorded, P19-003723 (the portion on the south side of SR-138) was identified as a multi-component site containing a moderately dense surface scatter of lithic artifacts and a sparse historic-period refuse scatter. Approximately 125 lithic pieces were collected from the surface of the site as part of a testing program in 2010, and excavations of shovel test pits within this portion of the site recovered minimal artifacts from the subsurface. A resurvey of this location in 2014 found that the nature and extent of the archaeological deposit to be consistent with what was recorded in 2010. Within the portion north of SR-138, thirty-three STPs and three test units were excavated within the site boundaries. As a result, a low-density artifact deposit was found to a maximum depth of approximately 70 cm below the surface. Two radiocarbon dates of charcoal samples tentatively place the site in the Late Prehistoric Period and possibly the Mission Period, although the contextual integrity of these samples is questionable. A total of 94 artifacts were collected from the site, with 62 resulting from the surface collection, 19 from the STPs, and 13 from the test units. Artifacts collected from the site include ground stone, lithic debitage, lithic tools, and a small amount of faunal bone and charcoal. An analysis of the lithics from the site indicated that all lithic artifacts were rhyolite. A total of 21.3% of the assemblage are shatter, 70.2% are flakes, 4.2% are cores, and 4.2% are lithic tools. Although the assemblage of lithics from the site is small in numbers and diversity, the analysis of the debitage, tools, and cores provides useful information. The primary activity at the site was likely the reduction of local rhyolite cobbles from the nearby Fairmont Butte which had already been significantly assayed with most of their cortex removed (since the assemblage has few primary flakes, and most flakes have little cortex). Early stage biface production is suggested by the high percentage of biface thinning flakes and the presence of one possibly rejected Stage I biface tool. In addition, the presence of a significant percentage of secondary flakes and exhausted cores suggests that production of flakes suitable for expedient tools or more finished flake tools was another activity practiced at CA-LAN-3723. There is very limited evidence of other activities at the site, consisting solely of a few expedient-use tools, one of the cores, and a small number of tertiary flakes. Though there are no diagnostic artifacts in the assemblage, the two radiocarbon dates offer modest support that the site dates to the Late Prehistoric and possibly the Mission Periods. This is an important finding that supports earlier work by Sutton (1982, 1988) and Scharlotta (2010a, 2010b, 2014) that argues that the Fairmont Butte rhyolite source was not restricted to early temporal periods such as the Pinto Period. It also could reflect use of this source by ethnographically known populations in the region during Late Prehistory and possibly the Mission Period. CA-LAN-4620 has been identified as a dense prehistoric lithic scatter located approximately 500 meters north of the Fairmont Butte rhyolite source and a major quarry and occupation site (CA-LAN1789/H). The site was previously part of an agricultural field, which resulted in disturbance and Archaeological Research Design for the Antelope Valley Study Area 50 07A3822 Task Order 17 mixing of the top 20-30 cm of soil within the plow zone. Previous plowing may have damaged some of the artifacts and the site’s proximity to Highway 138 and may have put the site at risk for looting. Twelve STPs and two test units were excavated within the site boundary. As a result, the site appears to contain a low density of artifacts to a maximum depth of approximately 50 cm below the surface. No intact features were noted on the surface or in the STPs. The total lithic assemblage from CALAN-4620 consists of a total of 388 artifacts, with 262 from the surface, 43 from the STPs, and 43 from the test units. A total of 99.5% of the artifacts were rhyolite, with two sandstone primary flakes recovered from the surface. The assemblage is comprised of shatter (10.8%), flakes (85.1%), cores (2.1%), and lithic tools (2.1%). Most of the cores and tools were recovered from the surface. Only one core and one tool were found subsurface. Because the rhyolite assemblage contains only about 8% primary flakes, and most flakes have little cortex, the primary activity at the site was likely the reduction of Fairmont Butte rhyolite cobbles that had already been significantly assayed and reduced (cortex removed). Early stage biface production is evident by the high percentage of biface thinning flakes and the presence of several possibly rejected or discarded Stage I biface tools which may have broken during manufacture. In addition, the recovery of a significant percentage of secondary flakes and cores suggests that production of flakes suitable for expedient tools or more finished flake tools was another activity practiced at CA-LAN-4620. Other than a single stage III biface recovered from the surface, there is essentially no evidence of other lithic reduction activities at the site. Given the absence of diagnostic artifacts in the assemblage and no chronometric dates, it is currently not possible to assign a temporal period to the site. The site is one of numerous sites near Fairmont Butte where rhyolite was being reduced into at least two products: early stages of bifaces and generalized flakes suitable for modification into other tools, apparently over a long period of time dating back to at least the Pinto Period. Tehachapi Mountains and Foothills Cottonwood Creek Site (CA-KER-303). Archaeological site CA-KER-303 is located on hills that extend south into the Antelope Valley where Cottonwood Creek comes out of the Tehachapi Mountains. Extensive excavations of the site were conducted by Roger Robinson between 1972 and 1977, although a final report was never published. CA-KER-303 is a large village site several acres in extent with a midden that is two meters deep in some places. Three structure bases (ovoid clay rings with a hard-packed earthen floor and carbonized posts) were exposed during archaeological investigations at the site (Sutton 1988b:62). There was a cemetery in the center of the site with burials representing at least 30 individuals. An adult female burial was accompanied by a total of 1,526 Mytilus disc beads, 1,055 Olivella disc beads, 32 complete and 13 fragmentary Megathura [limpet] rings, 6 Haliotis ornaments, and 3 steatite beads. The cemetery probably held many more individuals before it was vandalized. Trade goods found at the site include steatite, obsidian, and shell beads made from Olivella, mussel, clam (Tivela sp.), abalone, and Dentalium (Sutton 1988b:56). Rose Spring arrow points (indicating the Rose Spring Period) and Cottonwood Triangular arrow points (indicating the Late Prehistoric Period) were found at CA-KER-303. Radiocarbon dates indicate the site was occupied Archaeological Research Design for the Antelope Valley Study Area 51 07A3822 Task Order 17 from 2,400 B.P. (400 B.C.) (during the Gypsum Period) to 300 B.P. (A.D. 1650) (Sutton 1988b:74). The source report does not indicate whether or not the radiocarbon dates have been calibrated. San Andreas Rift Zone and San Gabriel Mountains Barrel Springs Site (CA-LAN-082). CA-LAN-082 was first recorded in 1949 and has been subsequently updated in 1974, 1977, 1985, 1988, and 1990. The site is centered on Barrel Springs in the San Andreas Rift Zone, near the mouth of Little Rock Canyon southeast of Palmdale. The site consists of at least five loci containing hearths, ground stone, burnt bone, midden, lithic tools, debitage, and Olivella beads. In 1988, Bruce Love conducted limited subsurface testing of the site. Significant subsurface deposits were identified. Radiocarbon dates from two features at the site indicate that the site was occupied as early as 5000 BP, indicating that the site likely has considerable antiquity and a long period of occupation. Objects including abalone shell, chert, and shell beads were imported from coastal regions; obsidian was sourced to the Owens Valley; and additional lithic materials were sourced to outcrops within the Antelope Valley up to 50 miles away (Love 1989). The arrow points, steatite and slate artifacts, ceramics, and Olivella beads indicate a Late Holocene occupation. Totem Pole Ranch Site. The Totem Pole Ranch Site is located south of Palmdale near the Barrel Springs Site. This site does not have a trinomial associated with it. Sutton 1988 notes that the site was exacavated by R. W. Robinson, but no report was ever prepared for the site. Artifacts that are known from the site consist of steatite and slate artifacts, including arrow points, artifacts, ceramics, and Olivella beads, which indicate a Late Holocene occupation (Sutton 1988b). The Totem Pole Ranch Site may be the Mission Period village of Maviayek (Earle et al 1997). Skelton Ranch Site (CA-LAN-488). Another village site, CA-LAN-488, the Skelton Ranch Site, is located on the south side of the Antelope Valley at the mouth of King’s Canyon near the San Andreas Rift Zone. The drainage in King’s Canyon brings water from the mountains to the south and cuts through the ridge that separates the rift zone from the Valley floor. When excavated in 1970, the site was about one acre in area; however, prior to a flash flood in 1969, CA-LAN-488 was two to three times larger. The midden is three meters deep and contains a diverse artifact assemblage. A sample from the mid-point of the deposit provided a radiocarbon date of 770 ± 90 B.P. (Sutton 1988b:74). Four burials were found at the site in 1970. One of them was an infant which had more than 5,000 Olivella shell beads associated with it. Rock art and bedrock mortars are known from nearby site CA-LAN-484 (Sutton 1988b:55). CA-LAN-488 may represent the Mission Period village of Pu’ning. At Indian Spring (Shea’s Castle) on the north slope of Portal Ridge (about 3.5 miles south of Fairmont Butte) there is a large habitation site with rock art (CA-LAN-721) (Earle 2015:28). This site may represent the Mission Period village of Timit or Sranijik. Cooper Creek Site (CA-LAN-1209/H). CA-LAN-1209/H is a high-elevation seasonal campsite located along Cooper Creek in the San Gabriel Mountains, near the southern boundary of the Antelope Valley Study Area. The site contains lithic debitage, tools, ground stone, bedrock mortars, faunal bone, charcoal, midden, and fire-affected rock. Seasonal occupation of the site has been dated to the late Gypsum Period, between 4000 BP and 1500 BP. The site was subsequently used seasonally from Archaeological Research Design for the Antelope Valley Study Area 52 07A3822 Task Order 17 1500 BP to 230 BP. The site was likely occupied by ancestral Serrano groups, who used the site as a base to exploit pinyon pine nuts, mule deer, and big horn sheep. Trade is evidenced by imported lithic materials, such as obsidian and fused shale (Milburn 2003). The site was used through the early historic period by European settlers as a hunting camp. Archaeological Research Design for the Antelope Valley Study Area 53 07A3822 Task Order 17 Geoarchaeological Sensitivity Model The geoarchaeological sensitivity model for the Antelope Valley is based on the landforms present in the valley and their potential to contain surface-level or buried archaeological deposits. The geoarchaeological sensitivity model was developed using geologic and geomorphologic desktop assessments of the area that included review of existing geologic maps, soil-survey reports, records search results, and other relevant data sources. Factors Influencing Buried Geoarchaeological Sensitivity/Potential Several primary and many ancillary factors can influence the potential for preservation and burial of archaeological site materials. Primary conditions include the type of geologic deposits associated with the landform present, the environment and energy of deposition of the deposits, the site landscape position, and any post-depositional events that may impact the buried deposits. Within the Antelope Valley region, whether archaeological materials were initially deposited on the various landforms composed of either igneous, metamorphic, or sedimentary deposits, the overlying geologic deposits that may bury and preserve the cultural materials are sedimentary in origin. These clastic deposits may have been derived from the weathering of any number of the surrounding source rock types and may have undergone very short or extensive transport history prior to burying the cultural layer. Landform Age The age of a landform, duration of active deposition, and stabilized surface exposure are also factors in geoarchaeological sensitivity. Resistant geologic deposits forming land surfaces that predate human occupation and have maintained exposure throughout human occupation (e.g., bedrock outcrops and resistant old alluvial deposits) by definition don't have potential for buried archaeological deposits. Alluvial fan, valley, and playa margin surfaces with stable exposure during periods of prehistoric occupation may subsequently be buried by younger sediments and may preserve potential occupation surfaces and associated archaeological artifacts. The determination of relative age and surface exposure for landforms and buried landform surfaces is, therefore, an important part of the geoarchaeological assessment. Based on the current understanding, the onset of human habitation in the Mojave Desert likely dates to no earlier than latest Pleistocene to early Holocene times (see Chronology section). Thus, it is safe to assume geological deposits that predate the late Pleistocene do not have buried archaeological sites or associated cultural materials. However, it should be cautioned that archaeological materials can and often do become mixed into and incorporated within the upper soil mantle of existing older geologic surfaces through natural soil-forming processes (i.e., bioturbation). Given the span of human occupation in the region, the sensitivity model will concentrate on the landscape setting and Archaeological Research Design for the Antelope Valley Study Area 54 07A3822 Task Order 17 geologic processes from the late Pleistocene to modern times as the primary control for the modeling of geoarchaeological potential of sediments. Lithology and Depositional Setting Whether the parent material of the source rock is sedimentary, igneous, or metamorphic in origin, sedimentary deposits are characterized by the assemblage of lithologic sediment types, their size, and the particle size distribution (size range) of the sediments. The weathering of the parent material and formation of the sediments and the transport mechanism(s) of the deposits generally control the size and range of sediments present. The size of the clastic sediments within a deposit is significant in that it is generally limited by the energy available for sediment transport. In the case of larger sized sediments such as larger gravels and cobbles or boulders (occurring within the proximal upper reaches of alluvial fans) the higher energy of transport necessary for these deposits may scour or erode potential habitation surfaces and remove or redistribute pre-existing cultural artifacts. Conversely, moderately- or well-graded deposits that have a range of finer particle sizes including silts and clay present, may produce deposits that blanket and bury cultural layers with negligible disturbance of the artifacts. Examples of these deposits are sheet wash and smaller scale ephemeral stream deposition on the medial and distal lower fan surfaces, as well as playa margin flooding and wind-borne eolian deposition. Geomorphologic Position The landscape position of archaeological sites in relation to subsequent geological processes can influence geomorphologic changes they may experience. Sites located in topographic basins, at the toe of slopes, or other natural zones of sediment accumulation will more likely be preserved than those on steep slopes, eroding ridges, or adjacent to other topographic breaks such as channel margins along stream terrace surfaces. Facing position and topographic elevation may correlate to soil-influencing biotic communities and average precipitation amounts and thus further influence site stability and preservation. Landforms of the Antelope Valley The Antelope Valley is an interior drainage basin formed by movement along the Garlock and San Andreas Faults (Ponti 1985). The formation of this basin is a relatively recent event, likely resulting from the uplift of the San Gabriel Mountains approximately 1 to 2 million years ago. Due to this geologically recent uplift, the Antelope Valley is almost entirely filled with Quaternary sediments (Ponti 1985). Landforms in the Antelope Valley that are critical in the assessment of archaeologic sensitivity include the alluvial fans, fan complexes, and playa shoreline margins; the eolian sand dunes, sheet sands, and lake bed surfaces in the eastern portions of the valley; and the hard rock buttes located throughout the valley. Archaeological Research Design for the Antelope Valley Study Area 55 07A3822 Task Order 17 Buried Site Sensitivity Model When determining the potential for buried sites, the age of sediments is used as the main discriminator in determining the potential for buried archaeological remains along with other factors such as geomorphological context and level of sediment distubance. The Antelope Valley is an enclosed interior drainage basin filled almost entirely by Quaternary (predominantly late Pleistocene and Holocene) alluvial and lakebed deposits. Based on the various geological formations mapped within the study area, four categories for buried site potential based on geological age (see the Chronology section for roughly equivalent cultural periods) were identified: Negligible Pleistocene-aged or older (14,000 years BP [12,000 BC] and older) Low Latest Pleistocene age (14,000 to 11,000 BP [12,000 BC to 9,000 BC]) Moderate Early Holocene-age deposits (11,000 to 8,000 BP [9000 to 6000 BC]) High Deposits from middle Holocene and younger (8000 BP [6000 BC] to present) Pleistocene‐aged or Older (14,000 years ago or older in age) Pleistocene-aged and older sedimentary units are considered to be extremely low in potential archaeological sensitivity due to their deposition prior to human habitation within the region. Within the Antelope Valley, these are predominantly represented by hard rock deposits and small exposures of old alluvial fan surfaces near the foothills of the San Gabriel and Tehachapi Mountain ranges. Latest Pleistocene Age (14,000 to 11,000 years) Late Pleistocene units are likely low in potential, based on the sparse and isolated nature of fluted point finds from that time (Sutton 1996). However, the presence of buried early period sites cannot be ruled out. Within the Antelope Valley, these are predominantly represented by small exposures of old alluvial fan surfaces near the foothills of the San Gabriel and Tehachapi Mountain ranges. Early Holocene-age Deposits (11,000 to 8000 years old) Early Holocene deposits are considered moderate in potential for sensitivity. While the Study Area was populated during this time frame, the known archaeological record is not as robust as seen during later periods. This may be an indicator of smaller populations or, as Eerkens et al. (2007) argue, this may be explained by the small percentage of older landforms that are currently exposed. The majority of Early Holocene deposits are located along the margins of the valley, near the Rosamond Hills, and along the ancient shoreline of Lake Thompson, southwest of Rosamond Lake. Middle Holocene and Younger Deposits (8000 years ago to present) Deposits from the middle Holocene and younger are considered highly sensitive, depending on other factors such as landscape position and proximity to major water sources. The majority of the Antelope Valley surface is made up of these deposits. Archaeological Research Design for the Antelope Valley Study Area 56 07A3822 Task Order 17 Quaternary Sedimentary Units within the Antelope Valley Study Area The majority of the valley floor is covered with middle and late Holocene alluvial deposits that are considered sensitive for containing un-recorded prehistoric sites. Table 7 presents the archaeological sensitivity of sediments within the Study Area based on the Bedrossian et al. (2012) geologic map. The geoarchaeological sensitivity map (Figure 5) shows the distribution of the deposits within the Study Area based on buried site sensitivity. Table 7. Quaternary Sediments within the Study Area.

In 1985, Daniel J. Ponti published a study of the Quaternary stratigraphic sequence within the Antelope Valley. Ponti argues that alluvial deposition within the Antelope Valley was likely rapid and episodic separated by periods of relative stability. He also argues that these periods of episodic alluviation correspond to climatic changes associated with transitions from glacial to interglacial periods (Ponti 1985). Ponti outlined six major alluvial units that appear throughout the Antelope Valley. Figure 6 shows the six major late Quaternary climatic events and their associated sedimentary deposits. Ponti’s stratigraphic units for the Antelope Valley are detailed in Table 8 below with their potential corresponding sedimentary units as presented in geologic maps of the area by Bedrossian et al. (2012). Table 8.

Late Quaternary Climatic Events and Associated Sedimentary Deposits Tylerhorse deposits date to between 300,000 and 140,000 years BP and predate human occupation within the Antelope Valley. Tylerhorse deposits tend to be confined to areas adjacent to mountains and are not prevalent in the valley floor. Tylerhorse deposits exhibit strong soil formation with welldeveloped argillic horizons and reddish-brown hues (7.5YR to 5YR in the Munson Scale) (Ponti 1985). Palmdale deposits (lower and upper) date to the late Pleistocene and early Holocene, respectively, and make up large portions of the Antelope Valley floor. Palmdale deposits have moderately welldeveloped soils with weak argillic horizons and lack the red hues of the Tylerhorse deposits. Both the Lower and Upper Palmdale deposits tend to be thick, regularly exceeding a depth of 10 meters. Of these, Upper Palmdale deposits are the most commonly exposed on the valley surface. Upper Palmdale deposits overlie/inter-finger with lacustrine deposits from Pleistocene and Holocene lakes (Ponti 1985). These deposits date to the early Holocene (8000 to 14,000 years BP) and may contain evidence of the earliest human occupation of the region. Post-Palmdale deposits date to the mid- to late-Holocene (8000 years BP to present). Post Palmdale soils are weakly developed and occur near active stream channels and depositional surfaces (Ponti 1985). Evidence of human occupation within the region is likely to only be found within the Upper Palmdale and Post Palmdale sediments and is not likely to occur in sediments below 17 meters deep. Soils within the Antelope Valley Study Area Fifty-six different soil series have been identified within the Antelope Valley Study Area (USDA 1970, 2019). Several of these are widespread throughout the Study Area, such as Adelanto, Cajon, and Rosamond series soils. Others have a smaller distribution or are localized in one location or geographic area. Table 9 shows the characteristics of the 56 soils series within the Study Area. Soil formation is a complex process that can be influenced by multiple factors including time, elevation, vegetation density, precipitation, temperature, and parent sediment/source rock composition. In general terms, the longer a landform is exposed and stable (not eroded), the more complex and developed the soil will become. Although soil formation is a complex process, soil development and horizon information can be used as a relative age indicator. Broadly, soils that are more well developed, particularly those that contain a B Horizon, or subsoil that contains accumulated mineral deposits, such as salts and calcium carbonate, are older than soils that are weakly developed, such as those containing only A- and C-Horizons (Holliday 2004:63). In 2018, Kremkau looked at soils data, including degree of development and sediment age, derived from geologic maps to develop a buried site sensitivity model for a small project near Lancaster. The model postulated that Sunrise Series soils likely developed in sediments from the late Pleistocene and had a low likelihood of containing buried archaeological deposits. Pond and Tray series soils were considered to have a moderate potential for containing subsurface resources. These soil series were also formed on sediments that ranged from the late Pleistocene to the Holocene. Hesperia and Rosamond series soils were categorized as having a high potential to contain buried resources as the sediments were formed on alluvium dating to the period from 2,000 to 5,000 years ago (Kremkau 2018).

portion of the northern Antelope Valley, in which they used archival research, soils data, sediment data, environmental data, and known radiocarbon dates to develop a map showing the age of individual landforms within Districts 6 and 9. To date, a similar comprehensive geoarchaeological model involving known radiocarbon dates, environmental variables, and in-field sampling has not been developed for the Antelope Valley as a whole and is outside the scope of the current research design. Hard Rock Units within the Antelope Valley Study Area Hard rock formations throughout the Study Area are varied and consist of a combination of plutonic, volcanic, sedimentary, and metamorphic rocks. Although hard rock formations are generally not factored heavily into geoarchaeological assessments, hard rock formations containing lithic source materials, rock shelters, caves, and outcrops near food-gathering spots are useful for predicting the potential for both surface and subsurface sites. Within the Study Area, hard rock formations are most prevalent in the adjacent San Gabriel and Tehachapi Mountain Ranges. Within the valley floor, hard rock formations make up the majority of the buttes and hills located throughout the valley. Table 9 presents the major bedrock formations within the Study Area based on a series of geologic maps by Thomas Dibblee, Jr. (1958-2008). Table 10. Major Bedrock Formations within the Study Area.

The Tropico Group is a grouping of Tertiary-aged (Pliocene to Miocene) sedimentary, pyroclastic, and volcanic rock formations that form the majority of the buttes and hills within the interior of the Antelope Valley including: Antelope Butte, Little Buttes, Fairmont Butte, Middle Buttes, Soledad Mountain, and the Bissell Hills. Tropico Group rocks also make up Castle Butte to the north of the Study Area and the Kramer Hills to the east of the Study Area (Dibblee 1967). Tropico Group formations, particularly the Bissell Formation, Gem Hill Formation, Kramer Hill Formation, and Fiss Fanglomerate, contain outcrops of tool-quality chert, jasper, and felsite/rhyolite-cobble-containing breccias (Dibblee 1967). Site Distribution Potential Based on Surface Landform In order to generate a predictive model for the location and distribution of archaeological sites across the landscape, certain assumptions about human behavior are made. For the Antelope Valley area, these assumptions include: people heavily utilized water sources for resource procurement, settlements tend to be located near water sources, people frequent areas where raw materials for tools are present, people frequented areas where plant and animal resources were prevalent (these Archaeological Research Design for the Antelope Valley Study Area 80 07A3822 Task Order 17 may have been seasonal), trade routes likely ran through passes in mountains and hills rather than over the mountains/hills. Using these assumptions, the following model for site distribution probability can be made: High Sediments along the margins and fluctuating shoreline of Pleistocene Lake Thompson. Areas within and near the natural ponds and water reservoirs formed by the playa and dune deposits on the margins of Rosamond, Buckhorn, and Rogers Dry Lakes. Terraces and banks along large drainage channels including Amargosa Creek, Old Creek, Mojave Creek, Big Rock Creek, and Little Rock Creek (in the southern foothills), and Cottonwood Creek and Oak Creek (in the northwestern foothills), particularly within the foothills where the creeks were more likely to have flowing water. Areas near springs and water seeps. Within the Study Area, these are particularly prevalent and within the San Andreas Fault Zone, although springs and seeps do occur near several of the larger buttes and hills within the valley and, prehistorically, were present at the location of modern Quail Lake. Areas immediately adjacent to lithic raw material sources. In the Study Area these include areas within and adjacent to the Rosamond Hills, Bissell Hills, Fairmont Butte, Little Buttes, Middle Buttes, and Soledad Mountain. Mountain passes. Within the Study Area, these include the San Andreas Fault Zone through the Leona Valley and the pass to the current Interstate 5 corridor. Moderate Alluvial fans and valleys. These were likely utilized for resource procurement and expedient processing. They may contain sparse artifact scatters but are less likely to contain intensive use sites. Mountain and foothill areas. May have been visited seasonally for juniper, pinyon, and other high elevation resource procurement. Low Developed areas. Top soils have been removed, mixed, and/or paved over in these areas. Human behavior is complex and is shaped by multiple natural, cultural, and internal variables. All predictive models should be taken with a grain of skepticism. Assumptions about prehistoric human behavior may be heavily influenced by researcher assumptions and sample biases. For example, there may be more recorded archaeological sites around certain landforms because that is where researchers expect sites to be and, in turn, is where studies are focused. For the Antelope Valley, by far the most heavily studied location is in and around Edwards AFB. The three surviving lake beds (Rosamond, Rogers, and Buckhorn Lakes) are all located within the Base boundaries and intensive studies of Base properties have been conducted for over 30 years. As a result, sites located near the Archaeological Research Design for the Antelope Valley Study Area 81 07A3822 Task Order 17 lakeshores may be overrepresented in the archaeological record while sites in the western valley and foothill areas may be underrepresented. In the Coso Basin, to the northeast of the Antelope Valley, early Holocene sites do not show any statistical patterning with respect to landforms, and prehistoric occupants of the region were likely utilizing a wider variety of areas than expected (Eerkens et al. 2007). Thus, while predictive models may be useful, areas considered to have moderate to low probabilities based on the assumptions above should not be ruled out without further investigation. Archaeological Research Design for the Antelope Valley Study Area 82 07A3822 Task Order 17 Ethnohistoric Period Introduction Five language/ethnic groups—the Desert Serrano, Tataviam, Kashtiq Chumash, Kitanemuk, and Kawaiisu (Nüwa)—are believed to have occupied areas in or near the Antelope Valley at the time of Spanish contact in the late eighteenth century. Approximate locations of villages occupied by these ethnic groups at the time of Spanish contact are shown in Figure 7. After native communities in the southern Antelope Valley were taken to the missions in the early decades of the nineteenth century, small groups of Chemehuevi/Southern Paiute from the eastern Mojave Desert visited and settled in the Antelope Valley after about 1830. Information about Spanish-contact era native settlement of the greater Antelope Valley region is derived from explorers’ accounts, Franciscan Mission records, and ethnographic research with native elders in the early twentieth century. Native communities living in the southern Antelope Valley were removed to the Franciscan missions by the 1820s. Native people from the Antelope Valley who left the missions after the mid-1830s moved to the vicinity of the Sebastian Reserve and the Tejón Reservation in the southeastern San Joaquin Valley between the mouths of Tejon Canyon and Grapevine Canyon by the early 1850s. Later native settlements in the Antelope Valley in the nineteenth century were composed mostly of in-migrating Chemehuevi/Southern Paiute. Thus, ethnographic information about contact-era native settlement in the valley was obtained from native elders living in other regions. This information is thus scattered and sometimes contradictory. A particular problem is the fact that named communities were frequently not precisely located by ethnographic consultants. Therefore, a reconstruction of the political geography of the greater Antelope Valley region is based on limited or fragmentary ethnographic and ethnohistorical information.

Village and Major Residential Base Locations 5 I 2015-075.017 Caltrans Antelope Valley Research Serrano speakers occupied the southern margin of the Antelope Valley. These communities appear to have had social ties with Serrano of the San Bernardino Mountains and San Bernardino Valley regions, as well as with the Desert Serrano of the Mojave River. The Big Rock Creek region and areas farther to the east were reported to be linked to the Serrano clan of the Amutskupeatam, located at Cajon Pass. Other communities of Serrano speech were located between Little Rock Creek and Pine Canyon to the west. The Liebre Mountain region, south of Gorman at the west end of the valley, was occupied by the Tataviam. The Kashtɨq Chumash had a village at Castac Lake located outside of the Antelope Valley Study Area to the northwest. Although their village was outside of the Antelope Valley, they may have gathered resources from a portion of the northwest Antelope Valley margin. The southern Tehachapi Mountains were occupied by the Kitanemuk, who were based in Tejon Canyon on the west side of the Tehachapi Mountains outside of the Antelope Valley Study Area. The Tehachapi Mountains slopes on the northwest side of the Antelope Valley, including the Cottonwood and Oak Creek drainages, appear to have been used by the Kitanemuk. Further to the northeast, the Kawaiisu occupied the Tehachapi Valley and the Piute Mountains to the north, outside of the Antelope Valley Study Area. However, they also gathered resources from the desert floor to the east of their Tehachapi Valley territory, extending across the northern part of the Antelope Valley Study Area, as well as into the Fremont Valley. The Kitanemuk and Kawaiisu also occupied the eastern margin of the southern San Joaquin Valley, but their ability to use San Joaquin Valley floor resources was constrained to some degree by neighboring Southern Valley Yokuts groups, with whom they were sometimes in conflict. The southern Antelope Valley Serrano groups, the Tataviam, the Kashtɨq Chumash, Kitanemuk, and Kawaiisu exploited upland or foothill food resources to support settlements near the mouths of canyons at the desert margin that could also take advantage of desert margin or desert floor resources in the Antelope Valley. Serrano-speaking groups in the southern Antelope Valley and on the Mojave River represented a desert-margin or desert-oasis adaptation of the montane Serrano. The Tataviam, Kashtɨq Chumash, and Kitanemuk also depended on oak, pinyon, and juniper tree resources found in more mesic foothill and upland areas away from the desert floor but could take advantage of desert resources from villages or camps located on or near the desert margin. The Kawaiisu, like the Serrano, in pre-Mission times extended their occupation far into the Mojave Desert, thus creating a true desert division of the group. The Kashtɨq Chumash (located at Castac Lake) formed part of a northeasterly extension of the inland Ventureño Chumash to the margins of the southern San Joaquin Valley. Elsewhere in southern and south-central California, a pattern of native occupation of the desertward margins of the Transverse Ranges and the southern Sierra can be observed, from interior San Diego County and the Coachella Valley to the Eastern Sierra. The location of villages at canyon mouths, foothill springs, or adjacent desert floor oases allowed the inhabitants to take advantage of both upland resources such as acorns, pinyon pine nuts, and upland game, and foothill and desert floor resources, including hard seeds, juniper berries, and mesquite, and lagomorphs as game. In both the Mojave River area and the Antelope Valley, pine nuts and acorns were also transported to camps and settlements located near the desert margin. Archaeological Research Design for the Antelope Valley Study Area 85 07A3822 Task Order 17 The arrival of Chemehuevi/Southern Paiute (who originally occupied the eastern Mojave Desert) in the Antelope Valley region by the 1830s or 1840s appears to have been initially linked to raiding stock from ranchos nearer to the coast. However, small groups of Chemehuevi/Southern Paiute settled for varying periods of time at valley floor oases and at spring sites and canyon mouth sites on the margins of the Antelope Valley where Serrano people had formerly lived. These newcomers intermarried with the linguistically closely related Kawaiisu during the course of the nineteenth century. They were also able to take advantage of the desert margin adaptation. The Serrano and Desert Serrano In his 1925 Handbook article on the Serrano, Kroeber recognized that they were divided into a Mountain and a Desert division, the latter occupying the Mojave River (Kroeber 1925:611-619). He also recognized that the Kitanemuk were a linguistically closely related group to the Serrano proper. Due to information he collected from a mixed Chemehuevi/Kawaiisu population at Victorville in 1905, he was not sure if the south side of the Antelope Valley had been occupied in ancient times by these latter Numic groups (Kroeber 1925:616). He was also uncertain whether their presence in the south side of the valley was very recent. He also recognized that the Serrano had traditionally been organized in localized patrilineal clans or sibs. Gifford (1918:178-186), Harrington (1986:III:101:52,86,344), and Strong (1929:11-29) also collected information on the Serrano clan system, including clan names and locations for both the Mountain and Desert divisions of the Serrano. The term clan was defined by Strong to denote a lineage-based corporate descent group that occupied a local territory, traced membership through the male line, and recognized the spiritual and ritual unity of the group under its hereditary chief and through its sacred bundle. The group was also exogamous, meaning that spouses had to be found outside the group, and also considered totemic, since either Coyote or Wildcat, and other affiliated totemic animals, were associated with each (moiety system). Strong specified that he used the term clan rather than lineage for the localized group in order to emphasize that the group identity was as much religious and ritual in nature as it was genealogical (1929:17). Harrington worked in 1918 with Santos Manuel and Tomas Manuel of the Yuhaaviatam clan of the Serrano at the San Manuel Reservation. They provided considerable new information about Serrano clans and social organization, including the moiety system, and about Serrano occupation of the southern Antelope Valley as far west as Big Rock Creek. Harrington had already collected a quantity of scattered information from various consultants at the Tejón Rancheria in 1916, including Kitanemuk-speakers Eugenia Mendez and Magdalena Olivas, about groups of Serrano-speakers that had formerly lived on the south side of the Antelope Valley (Harrington 1986:III:98:54-57, 502-503, 521-523,586,674-676). They also provided information about the location of Tataviam settlements near the west end of the valley, and about named places on the northwest side of the valley. Archaeological Research Design for the Antelope Valley Study Area 86 07A3822 Task Order 17 The ethnographic information collected in the early twentieth century about Serrano clan territories and their locations, and about Serrano social organization, has been compared by Earle with earlier information from Spanish colonial era documentation (Earle 1990, 1996, 2004d, 2005; Sutton and Earle 2017). Key Spanish documents included the expedition diaries of Pedro Fages (1772), Francisco Garcés (1776), Fr. José María Zalvidea (1806), José Palomares (1808), and Fr. Pascual Nuéz (1819), as well as Franciscan mission baptismal and other records (Bolton 1935; Cook 1960; Coues 1900; Earle 2010b; Palomares 1808). Because the Antelope Valley and the Mojave River lay beyond the limits of regular Spanish settlement (limited to the coastward side of the transverse ranges), the desert margin regions were only sporadically visited by military expeditions. Some of these expeditions did not leave diary accounts (but are mentioned in other sources), including a number after 1810 that may have involved pressuring Mojave River and Antelope Valley native villagers to move to Missions San Gabriel and San Fernando. For both the Mountain and Desert divisions of the Serrano, the Spanish-era accounts and baptismal records generally support the ethnographic information indicating the existence of patrilineal territorial clans or sibs. Usually the places of origin for baptized natives listed in Franciscan baptismal records appear to correspond to either a principal village within such a clan territory or to the name of the clan group itself. Sometimes the names of the principal settlement and of the clan group appear to have been the same. Ethnographic consultants recalled many of the clans mentioned in Spanish records, and even recalled their boundaries, while others, or their locations, had been forgotten by particular consultants. This tended to be the case where certain clan villages had been completely recruited to the missions, and the corresponding clans had not been reconstituted in any form by mission survivors or holdouts after the end of the mission system. Franciscan baptismal and marriage records also provided key information about inter-village marriage links. Members of Serrano clans were required to seek spouses in other clans, and baptismal records at Mission San Gabriel, beginning in 1810, accurately reflected this practice of exogamy. Thus, ethnographic information provided details about the Serrano clan or sib system, while Spanish-era documents have complemented the information from Serrano elders about the locations of clans and villages. In respect to the Antelope Valley, the 1776 expedition diary of Franciscan Explorer Fr. Francisco Garcés, analyzed by Earle (1990:94-96), has supported ethnographic information suggesting that the southern Antelope Valley was occupied by Serrano-speakers (Coues 1900:I:234-308). In addition, the diary indicates that these Serranos were a distinct group from the Kitanemuk of the Tehachapi Mountains. After traveling up the Mojave River, and then visiting Mission San Gabriel, Garcés returned to the edge of the desert at the southwest margin of the Antelope Valley. At the village of Kwarung at Lake Hughes he noted having returned to the territory of the Beñemé or Desert Serrano, whom he had met on the Mojave River (Coues 1900:I:267-270). His information about ethnic groups and boundaries was supplied by his accompanying Mojave guides. At the village of Kwarung were visitors from the territory of the Kitanemuk, who were clearly treated by his guides as a separate ethnic group. Archaeological Research Design for the Antelope Valley Study Area 87 07A3822 Task Order 17 Serrano Social Organization and Settlement Gifford (1918:178-186), Strong (1929:5-29), and Harrington (1986:III:101:52,86,344) collected information from native elders about Serrano social organization. Strong had also carried out research with the Cahuilla, Luiseño, and Cupeño, and discussed similarities and differences in the social organization of these groups (Strong 1929:15-22, 59-62, 163-168). He emphasized that individual clans (sibs), as independent groups, had a special sacred and supernatural identity as a group that was embodied in what he called the sacred bundle. This was a collection of sacred objects (sea grass, yucca fiber, or tule matting) that enclosed sacred items, including magical wands, shell beads, feathers, rattles, and other ritual paraphernalia. This was kept in the custody of the chief, or possibly another ritual officer. The clan had a sacred house, within which various ceremonies were held. Strong believed, from what he was told, that in traditional times the sacred house was occupied by the chief. While the chief also exercised political functions, including the maintenance of alliances with other groups, Strong believed the chief's ritual functions were of great importance in maintaining the identity of the group. Thus, recognition of a particular chief to perform ritual activities, and recognition of the sacred bundle that he cared for, defined who the family groups or 'lineages' were that might make up a clan or sib. The chief was supported by a ritual assistant or master of ceremonies, the paha, and a hereditary singer, tcaka, in charge of the singing of sacred clan songs. Chiefs were leaders of autonomous patrilineal territorial clans. There is no indication of the existence of regional chiefdoms or paramount chiefs. Nevertheless, two of the San Bernardino region Serrano clans, Aturiavatam and the Marengayam, apparently made rival claims about being the senior or influential clan group in the region. Harrington and other ethnographers collected information about a moiety system found among the Serrano and Cahuilla, involving the Coyote and Wildcat moiety divisions. Coyote and Wildcat were the most prominent animal totems for the two moiety divisions, but other animals were featured in each as well. All clans were classified as belonging to one or the other of the moiety divisions. A person from a Wildcat division clan was expected to seek a spouse in a Coyote division clan. Communities that intermarried in this way, or otherwise had close alliance ties, would assist one another in the holding of ritual activities like the Mourning Ceremony. A key element in Serrano social organization was the idea of reciprocity between the different territorial clans. The holding of rituals like the mourning ceremony involved various forms of ritual reciprocity between the host clan sponsoring the ceremony and allied and guest clans that participated. This included assistance in carrying out ritual activities and exchanges of gifts and offerings, including the prestation and counter-prestation of special strings of shell beads. Both ethnohistorical and ethnographic information also record the importance of resource reciprocity clans lending and borrowing large quantities of food resources, sometimes through lending or borrowing access to food resource areas between allied clans. In addition, fiestas were also held where guest clans were invited to gather resources like acorns or pinyon pine nuts, and/or to hunt, over a period of days, as a part of the fiesta. These alliance relations served to even out access to food resources between different clans. Archaeological Research Design for the Antelope Valley Study Area 88 07A3822 Task Order 17 Clan or sib groups of the San Bernardino Mountains region often reflected a settlement system taking advantage of access to upland and lower elevation resources similar to the desert margin strategy in the Antelope Valley. Residents of winter villages located on lower mountain slopes near canyons could ascend into the higher elevations of the San Bernardino Mountains during the summer months where seasonal camps were occupied for hunting and plant foraging. In this yellow pine forest zone, temporary conically-shaped dwellings of tree branches and pine bark slabs were constructed. The exact boundaries of clan territories in the high country were recalled by Harrington's Serrano consultant Santos Manuel. In the spring and summer, mountain slope chaparral plants such as yucca (spring) and sage (salvia) and other hard seeds (summer) were exploited. The Serrano gathered acorns, pinyon pine nuts, and islay (holly-leafed cherry) at intermediate elevations during the autumn. Sometimes special camps were established during the autumn for gathering of tree crop resources and rabbit and deer hunting to lay away extra stocks of food for hosting an upcoming winter season mourning ceremony. Thus, clan populations could disperse to temporary camps in spring, summer, and autumn. During the winter months, when the mountain camps were snowbound and storms were more common, lower altitude village sites were occupied during and after the fiesta season. Consultant Santos Manuel noted, for example, that for a clan group living to the east of Yucaipa, the winter village was better suited for riding out winter storms than the acorngathering camps. This was also a period for craft activities and equipment repair. Winter villages included the chief's house and associated ramada, an outdoor dancing plaza (often enclosed) a cemetery, a temescal or sweat lodge, acorn granaries, and other storage features and facilities for individual households. Individual dwellings were made of saplings tied into a hemispherical framework that was covered on the outside with tule reed thatching, and on the inside with tule reed matting. Floors were excavated below grade, and also covered with matting. Winter villages were considered permanent from year to year, although the resident population varied at different seasons of the year. Individual dwellings had to be located sufficiently far apart so that a dwelling could be burned as part of a funeral observance. Over longer periods of time, the exact locus of habitation of a settlement in some cases appears to have shifted. Serrano Mortuary Behavior and the Mourning Ceremony Strong states that it is probable that the Serrano shared with other Takic-speaking groups, such as the Cahuilla, the custom of cremating their dead (Strong 1929:32). Kroeber (1925:618) also mentions cremation. The Serrano version of the religious account of the death and cremation of a culture hero named Kukitat at Big Bear Lake may have provided a cultural charter for the practice of cremation. The Serrano recalled origin stories that commemorated two brothers, Pakrokitat and his younger brother Kukitat, who created the human race and quarreled over how humans were to be endowed. Pakrokitat withdrew from the world of men, and Kukitat divided mankind into warring groups, and created death. He was then slowly poisoned by disgruntled followers and cremated at a site on Big Bear Lake. A part of his body was stolen by Coyote during the cremation. The Serrano stories reflect beliefs which may have been shared with other groups in both the Colorado River region and southern California coastal areas. Versions of this story are also found among other Takic-speaking Archaeological Research Design for the Antelope Valley Study Area 89 07A3822 Task Order 17 groups. Strong surmises that after Spanish contact the Serrano interred their dead, a change of custom which he attributes to missionary influence (Strong 1929:32). After a person's death, some of his or her personal property was immediately destroyed. The deceased’s house was burned. An additional ceremony called the mamakwot was held soon after the death, perhaps a week to a month later (Benedict 1924:382). This was sponsored by the bereaved family. A feast was held, and the personal property of the deceased, with a few exceptions, was burned or broken up. It was believed that if this were not done, the deceased could not be left in peace. As was the case with other southern California groups, a mourning ceremony was held periodically by a clan to honor all the clan's members who had died since the last ceremony. The mourning observance was the major ceremonial event on the ritual calendar. It appears to have been held on a regular annual basis and involved reciprocal obligations between different clans. A significant number of clans might be invited to the mourning ceremony. Benedict was told, for instance, that in former times the hosts of the ceremony she attended might have invited some six other clans (Benedict 1924). The ceremony was held after the close of the fall acorn and pinyon harvests. It was important for the harvesting tasks of autumn to be completed so that the investment of time necessary to host the ceremony could be made. It was also necessary that foodstuffs be available to underwrite the feasting. It is particularly important to keep in mind that a considerable block of time in late fall and early winter was taken up almost exclusively with either hosting or attending the mourning ceremonies, as the various clans held their ceremonies in succession. Duncan Strong witnessed a joint Serrano-Cahuilla mourning ceremony in the mid-1920s (Strong 1929:122-130). The singing of special songs by the host clan chief and by shamans to verify that the time was propitious for the ceremony took place on Monday, Tuesday, and Wednesday, along with singing by host and visitor clans. The latter sang on Wednesday and Thursday. On Friday night, the sacred bundle was brought out of the inner room in total darkness, prayers said, and then it was returned to its inner room before fires were relit. On Saturday afternoon the funeral images were completed, and these were paraded and danced with in public. The evening of Saturday was devoted to the singing of songs about creation by visiting clans in the dance house, while in the courtyard game-playing and visiting went on. On Sunday morning food was distributed to all visiting families. Then the images were paraded again and then taken to the cemetery to be burned. As in the ceremony witnessed by Benedict, gifts were then thrown to the crowd, and shell bead strings distributed to visiting clans. The mourning ceremony was the most important of a number of inter-clan gatherings or fiestas that linked Serrano clans together. The various clans were bound together through shared ritual activity, the exchange of food and artisan goods, and cooperative activities such as joint acorn or pine nut gathering. Archaeological Research Design for the Antelope Valley Study Area 90 07A3822 Task Order 17 The Desert Serrano and Antelope Valley Settlements Groups within the desert division of the Serrano occupied the Mojave River and also southerly portions of the Antelope Valley. As discussed in detail elsewhere (Sutton and Earle 2017), settlements along the Mojave River relied in part on the importation of upland nut and berry foods - acorns, pine nuts, and juniper berries - along with locally available mesquite, to support village populations along the Mojave River linear desert oasis. In the southern Antelope Valley, canyon mouth and spring sites provided settlement locations that could take advantage of nearby upland resources, as well as foothill and desert floor plant and animal food resources. Several Antelope Valley region settlements which are named in the mission registers and are believed to have been of Serrano or Desert Serrano affiliation are listed below. Several of these settlements, including Kwarung, Maviayek, Puning, Pavuhavea, and Amutskupiat, appear underrepresented in the Mission San Fernando and San Gabriel sacramental registers. It is not clear whether members of any of these communities may have been baptized under a linguistically different version of the corresponding village name. Some inhabitants of these places may have avoided missionization, and later migrated to the Los Angeles Basin or to the southern San Joaquin Valley. These named villages have in some cases been at least tentatively located, on the basis of inferences from expedition accounts or data provided by Harrington consultants. Amutskupiat. Serrano elder Santos Manuel placed this settlement in Big Rock Creek, approximately opposite the later Valyermo Post Office. Manuel said that it was affiliated with the Serrano clan based at Amutskupiabit (Cajon Pass). Sgt. José Palomares reported in 1808 that a village of this name was located somewhere to the east of Maviayek (Little Rock Creek), corroborating Manuel’s account (Palomares 1808:232-234). Maviayek. Maviayek was mentioned by Kitanemuk consultants Magdalena Olivas and Eugenia Mendez as a community associated with a mountain zone on the south side of the Antelope Valley in the general vicinity of Soledad Pass and to the west of the mountains in the vicinity of Big Rock Creek (Harrington 1986:III:98:523, 528, 599). Its name refers to an extensive riparian gladed area, and it was said to be associated with a large marsh and was near where sugar carrizo grass grew (Anderton 1988:385-386). Maviayek may be associated with the archaeological site of CA-LAN-184 located at the west end of the Garcia Cienaga (marsh) where there was a cottonwood forest on lower Little Rock Creek. In the fall of 1808 Maviayek was visited by the Palomares expedition, as it had been reported by a chief at Kwarung that neophyte runaways were being harbored there (Cook 1960:245). Palomares found most of its inhabitants absent at an acorn gathering fiesta hosted by the chief of the Serrano village of Guapiabit in Summit Valley, some 40 miles to the east (Palomares 1808:238-241). Inhabitants of this village don’t appear to have been baptized under this name at Mission San Fernando. Chivung [Tsivung]. This community and its inhabitants were recalled by Kitanemuk consultants. It was placed on the south side of the Antelope Valley to the west of Soledad Pass. Given that its name refers to ‘bitter water’, it has been tentatively placed at the upper end of Amargosa Creek in Leona Valley (Harrington 1986:III:98:676). Some 33 inhabitants of Tsivung were baptized at Mission San Archaeological Research Design for the Antelope Valley Study Area 91 07A3822 Task Order 17 Fernando, many of them in 1811 in what appears to have been a military roundup (Huntington Library 2006). Chivung had five marriage ties with the Tataviam village of Kwitsa'ong at Liebre Mountain to the northwest. It also had marriage links to the Desert Serrano village of Topipabit on the Mojave River. Around two-thirds of those baptized were adults (aged 15+), suggesting the possibility that epidemic disease had previously impacted the community’s juvenile population. The original population would thus have been larger, probably exceeding 50 people. Epidemics of dolor de costado (typhoid fever) and measles had occurred in southern California in 1801 and 1806, respectively. Kwarung. This settlement was located at Lake Hughes, probably at a marsh east of the east end of the modern lake. Harrington’s Kitanemuk notes contain a location for the place at Lake Hughes, and Capt. Pedro Fages (1772), Fr. Francisco Garcés (1776), and Sgt. José Palomares (1808) all visited the community (Coues 1900:1:268-269; Cook 1960:245). While King and Blackburn (1978:536) believed that Kwarung was of Tataviam affiliation, Garcés noted that upon arriving at the place he had returned to the territory of the Beñemé or Desert Serrano. Thus, it has been identified as of Serrano speech. When Palomares visited the place in the autumn of 1808, a fiesta of some sort was underway. Pu’ning. The exact location of Pu’ning is unknown. Pu'ning was placed by Eugenia Mendez somewhere “back of the mountains of San Fernando” (the transverse range) on the southwest side of the Antelope Valley (Harrington 1986:III:98:675-676). At least four members of this community were baptized at Mission San Fernando in 1803, one of which had a marriage link to an unlocated village named Tomijaibit (Huntington Library 2006). Mendez stated that, “Old Rogerio, captain, of San Fernando, was Pu'nijam” (Harrington 1986:III:98:676). The settlement was referred to along with Pavuhavea and Chivung [Tsivung] as ‘nations’ of Serrano speech located in the same general region on the southwest margin of the Antelope Valley. Pavuhavea. This village has also not been located. This was described as, “a place over beyond La Liebre back of the mountains of San Fernando. Used to be a ranchería [village] of cazadores [hunters] there. It is an aguaje [spring]. In the vicinity of tsivung, pu'ning, etc.” (Harrington 1986:III:98:675). It was located somewhere in the southwestern Antelope Valley foothills. It was also associated with “lluvidores” (rainmakers?) and with a story about a man who died and came back to life from the land of the dead four days later (Harrington 1986:III:98:21). Timit oSranijik. This locality was described by Magdalena Olivas as “A place a little this way [toward the Tejón region] from Elizabeth Lake, between Elizabeth Lake and the Ojo de la Vaca” (Harrington 1986:III:98:674). Ojo de la Vaca referred to Pujutsiwaming or Cow Springs, possibly a Tataviam settlement. The Kitanemuk Serrano name Timit oSranijik was translated as 'La Piedra Pintada' or Painted Rock. This is obviously a reference to a rock art site. At Indian Springs, on the property of what became known as Shea's Castle, located midway between Elizabeth Lake to the southeast and Fairmont Butte to the northwest, is a prominent rock art site. The rock art panels at the site, CA-LAN-721, are associated with an extensive habitation area. It is possible that Timit oSranijik was associated with CA-LAN-721. Apavuchiveat. This named place on the Antelope Valley desert floor was either a camp or a more permanent settlement in proto-historic times. It was described by Serrano elder Santos Manuel, who Archaeological Research Design for the Antelope Valley Study Area 92 07A3822 Task Order 17 had visited it as a young man. From his description, Harrington believed that it was located at Buckhorn Springs, between Rogers and Rosamond Dry Lakes on Edwards Air Force Base. The Tataviam In the 18th century, the Tataviam occupied an area that included the upper Santa Clara River drainage in and around the Santa Clarita Valley and adjacent mountain ranges. This included an area of mountain ridges extending northward from the upper Santa Clara River toward the Antelope Valley, as well as the headwaters of that river northeast of Santa Clarita. It also included the drainage of upper Piru Creek. Very limited ethnographic work was carried out with Tataviam-speakers by Harrington and other ethnographers. Thus, the language remained poorly documented, leading to some uncertainty among linguists and ethnographers as to the linguistic and cultural relation of the Tataviam to neighboring groups. However, as noted by Johnson and Earle (1990:191-192) in their discussion of the Tataviam, Harrington's Kitanemuk consultants provided sufficient information to confirm the close relationship of Tataviam to other Takic languages. Tataviam Settlement and Subsistence In August of 1769, Tataviam villages in the Santa Clarita region were visited by the Portolá expedition, which made reference to at least five occupied villages (Crespí 2001:358-371). Dwellings appear to have been generally similar in type to those used by the Serrano. At one of these settlements, over 100 people were noted (Crespí 2001:362-363). In addition, in the central Santa Clarita Valley area, the expedition observed a 'corral' like-structure that may have been a ceremonial dance enclosure. Villages in the area may have averaged 100-120 people in population, although the village of Tsawayung may have been larger. Other Tataviam villages were located in the canyons north of the Santa Clarita Valley. This upland area extended from upper Piru Canyon to Soledad Canyon on the east, and included Liebre Mountain, near the west end of the Antelope Valley. Major north-south trails reached Tataviam settlements on upper Piru Creek, and ascended Violin Canyon to reach the village of Pakahung south of Gorman. These trails provided access to the southern San Joaquin Valley. Further east, another trail ascended Castaic Creek to reach the Tataviam village of Pi'ing, near modern Pyramid Lake, and, further north, the village of Kwitsa'ong, on the south slope of Liebre Mountain. North-south trails also led up Elizabeth Lake Canyon, San Francisquito Canyon, and Soledad Canyon to the east. On the south side of the Liebre-Sawmill-Sierra Pelona Mountain ridge that fronted the southwest rim of the Antelope Valley was a transverse fault canyon cutting across north-south canyon trails. This provided both a travel route and watered camping places for upland foraging. Upper Soledad Canyon and surrounding areas, including Vazquez Rocks and Acton, have been placed within the territory of the Tataviam (King and Blackburn 1978:535; Johnson and Earle 1990:194). In the Santa Clarita Valley region, oaks were formerly abundant. The Portolá expedition accounts mention acorns, juniper berries, and small hard seeds such as chia being observed in this area. Archaeological Research Design for the Antelope Valley Study Area 93 07A3822 Task Order 17 Stands of juniper in the Camulos area were an ethnographically noted food source. Further north, in the Soledad Canyon drainage and surrounding hills, the harvesting of Yucca whipplei was a key activity carried out in the spring. This was one of the first major food resources available during the year. King et al. (1974) studied prehistoric Yucca harvesting and roasting in the vicinity of Vazquez Rocks, just northwest of Soledad Canyon. Large quantities of juniper berries would also have been available for harvest in late summer in this area, and juniper fuel wood was used for yucca roasting. This area lies below 1,640 ft. (500 m.) and is significantly drier than higher altitude mountain slopes and canyons further to the west and northwest. There, the more shaded slopes of the narrower canyons at higher elevations support more robust chaparral, along with scrub oak and canyon live oak, and pinyon- juniper woodland at higher elevations. Chia (Salvia spp.) and islay (Prunus ilicifolia) were found in the canyons in this area as well. Oak woodland is also found at high altitude, as on the crest of Liebre Mountain, where acorns were gathered by ex-neophytes from Mission San Fernando. The southwesternmost corner of the Antelope Valley along the north-facing slopes of Liebre Mountain supported dense oak woodland. The base of the north slope of this mountain was traversed by the San Andreas Fault, which contributed to sag ponding and the availability of water. Tataviam Social Organization Franciscan baptismal registers provide information about Tataviam chiefs. They appear to have been politically independent and to have inherited their position in the male line (Johnson and Earle 1990:198-209). Tataviam villages like Kwitsa'ong and Hwit' ahovea, on the north side of Liebre mountain, may have had far-reaching political ties, since the Tataviam of the Western Antelope Valley were listed by a Serrano ethnographic consultant as part of the social or interaction sphere of the Serrano of the San Bernardino Mountains. Spanish-era ethnohistorical sources provide some important inferences about social organization. Marriage ties between Tataviam communities and with non-Tataviam groups were recorded in baptismal and marriage registers at Mission San Fernando, where most Tataviam neophytes were baptized. Beginning soon after the founding of nearby Mission San Fernando in 1797, significant numbers of Tataviam from the Santa Clarita Valley were baptized during the following decade. This recruitment, voluntary or forced, continued for villages in northern Tataviam territory after 1810, when renewed efforts were made to bring native people into Missions San Gabriel and San Fernando. Pre-mission native marriage ties of the Tataviam with the neighboring Fernandeño and Ventureño Chumash were recorded. The ranchería of Camulos was a mixed Tataviam-Ventureño Chumash community, for example. The village of Kwitsa'ong on the southern slope of Liebre Mountain, just over the ridge from the Antelope Valley, intermarried with the Serrano speaking village of Tsuvung, probably located in Leona Valley, also on the southwest margin of the Antelope Valley. Regarding the organization of kin groups into community units, we do not have clear indications of a system similar to that of the Serrano, who were organized on the basis of exogamous patrilineal clans with a chief and headquarters village. We also have no indication of the existence of totemic Archaeological Research Design for the Antelope Valley Study Area 94 07A3822 Task Order 17 moieties. Given the location of the Tataviam, wedged between the Gabrielino and the Ventureño Chumash, we could consider the possible social organizational alternatives of its neighbors. On the one hand, large Takic-affiliated coastal communities, such as found among the Luiseño, were made up of a number of constituent patrilineal kin groups. On the other hand, for the Chumash, María Solares reported what appear to be non-localized (or non-territorial) patrilineal clans (diffuse regional clans, rather than localized territorial ones). Given that the size of most Tataviam villages did not exceed 120-150 people, we do not consider it likely that subsidiary chiefs and their kin groups existed within these communities, although it cannot be ruled out. Tataviam Religious Institutions and Mortuary Customs Blackburn and King (1978:536) suggest an association of the Tataviam with the 'Antap cult of the Chumash, partly on the basis of their association with the famous cache of ritual paraphernalia found at Bowers Cave in Tataviam territory. In addition, the Portolá Expedition mentioned seeing what they interpreted as 'Antap-style ceremonial enclosures. These were reported at an historic Tataviam village in the mid-nineteenth century (Harrington 1986:III:98:164-165). The Bowers Cave ritual items and basketry bear similarities to Ventureño Chumash and Kitanemuk paraphernalia and even some Fernandeño/ Gabrielino materials. Their location, well within historic Tataviam territory and apparent contact-era date, suggests connection with Tataviam religious ritual. While the 'Antap cult itself was not found among the Kitanemuk, being considered a coastal phenomenon, a number of other practices, including interment, the use of grave poles and sun staffs were shared by the Kitanemuk with the Ventureño Chumash and immediately neighboring Chumash groups. These would thus likely have been found among the Tataviam, closer to the coast, as well. In addition, the Chumash 'Antap and Gabrielino/Fernandeño Chingichnich cults, of apparent southern California island origin, were probably shared by at least some Tataviam communities. The Tataviam villages in the general vicinity of Bowers Cave had close ties with the Ventureño Chumash of the lower Santa Clara River Valley. It is noteworthy that members of the Portolá expedition observed among the Tataviam both elaborate beadwork belts and the stone knife-tipped polished rods worn in the hair of chiefs that were characteristic of Chumash chiefs (Crespí 2001:366-367). As King et al. (1974:45-46) have noted, even for the Late Prehistoric period the archaeological evidence suggests a mixed occurrence of inhumation and cremation within and outside of Tataviam territory. McCawley (1996:157) quotes Harrington’s statement that the “coast Gabrielino both buried and burned the dead as far south as [the] mouth of [the] Santa Ana River.” Cremation, therefore, does not appear to have been universally practiced, with coastal Gabrielino groups and those living in closest contact with the Chumash more likely to practice interment to some degree. The Ventureño and Castac Chumash and the Kitanemuk, western and northern neighbors of the Tataviam, however, practiced inhumation rather than cremation. Regardless of whether cremation or interment was practiced, all of these groups shared the practice of erection of grave poles decorated with feather wands, baskets, and painted bands. Archaeological Research Design for the Antelope Valley Study Area 95 07A3822 Task Order 17 Both the Chumash and Southern California Takic groups, coastal and interior, also shared different versions of the periodic mourning ceremony, a memorial fiesta held annually or periodically to honor all persons who had died since the last ceremony. This ceremony has been described for the Serrano, and its characteristics for the Gabrielino/Tongva and Tataviam appear to have been somewhat similar. Arrangements of ritual reciprocity would have been structured between different community and clan groups in the absence of the Wildcat and Coyote moiety system found in the Southern California interior. Named Tataviam Communities on the Antelope Valley Desert Margin Hwi't ahovea. Hwi't ahovea was located at the site of the historic Liebre Ranch House, located in Tentrock Canyon on the north side of Liebre Mountain at the west end of the Antelope Valley (Harrington 1986:III:98:32,672). In the late nineteenth century, a number of house rings were still visible at the village site, to the southwest of the ranch house (Benson 1997:148). Kitanemuk consultant Eugenia Mendez had visited the ranchería site, then being used as a temporary campsite, before the ranch house was built circa 1863 (Harrington 1986:III:95:243, 98:598). She translated Hwi’t ahovea as “Cueva de la Liebre” in Spanish, or “Cave of the Jackrabbit” in English. At least four people from this place were baptized at Mission San Fernando in 1811. A main north-south native trail passed southward from Hwi't ahovea over the top of Liebre Mountain to reach another important Tataviam settlement called Kwitsa'ong [Cuecchaong] and points further south. This same trail ran northward from Hwi't ahovea across the west end of the Antelope Valley to climb the southeast slopes of the Tehachapi Mountains as it entered Kitanemuk territory. Kwitsa'ong. Directly south of the summit of Liebre Mountain lies the upper northerly end of Cienaga Canyon, the apparent location of the Tataviam ranchería of Kwitsa'ong. Some thirty- three people from this village were baptized in late March and early April of 1811 (Huntington Library 2006; Temple n.d.:Bapts., 49-54). .This was possibly the result of a military roundup. The population of this community had been larger than indicated by the baptismal totals, as indicated by the age distributions of those baptized. The native chief of Kwitsa'ong, Alaguo, and his family were baptized as part of the 1811 group. This community had marriage ties with a number of communities. These included Shuxwiyuxus, a Chumash village in Hungry Valley to the west, Hwi’t ahovea, the Desert Serrano village of Tsivung, probably located in Leona Valley, and possibly Pujutsiwaming, at Cow Springs, discussed below. By the 1830s, this site had been re-occupied by a small group of ex-neophytes from Mission San Fernando Pujutsiwaming. Pujutsiwaming was located at Cow Spring, on the southwest side of the Antelope Valley, several miles to the east of Hwi't ahovea. It appears to have been a village settlement. Five people baptized at Mission San Fernando in April of 1811 appear to have originated at this community (Huntington Library 2006; Temple n.d.:Bapts.,50-53). It was possibly of Tataviam speech, given its proximity to Hwi't ahovea. Archaeological Research Design for the Antelope Valley Study Area 96 07A3822 Task Order 17 The Kitanemuk In the late eighteenth century, the Kitanemuk occupied a portion of the Tehachapi Mountains south and possibly west of the Tehachapi Valley. Their territory included the southeast slopes of the Tehachapi Mountains, so they may have used adjacent portions of the Antelope Valley on a seasonal or more permanent basis (King and Blackburn 1978:564). The Kitanemuk spoke a language very closely related to the Serrano spoken in the San Bernardino Mountains. Due to the linguistic research of John P. Harrington on Kitanemuk in 1917, and later analysis of the language by Alice Anderton and other linguists, this well-attested language is technically considered a separate language from Serrano proper, although very closely related. Kitanemuk speakers told Harrington that their language and the Serrano of San Bernardino were mutually intelligible. Despite this close linguistic connection and social interaction with the desert and mountain divisions of the Serrano, the Kitanemuk appear to have developed some cultural features different from those of the Serrano. These features may be related to the fact of their having the Kashtɨq Chumash, southern Valley Yokuts groups, and the Kawaiisu as neighbors. Kitanemuk Settlement and Subsistence Kitanemuk settlement in the Tehachapi Mountains and foothills was centered in the Tejón Creek Canyon and adjacent areas, to the southwest of the Tehachapi Valley. The Tejón Ranchería, a famous 19th century native settlement that included Kitanemuks and people from other tribes, was located at the mouth of Tejón Canyon on the east side of the southern San Joaquin Valley. Harrington was told by Kitanemuk consultants that the territory of the group had formerly extended further downslope and westward, with centers of settlement at El Monte and the Tejón Ranch house (Harrington 1986:III:98:56). The Kitanemuk were bounded on the west by southern Valley Yokuts groups with whom their political relations often involved conflict. In contrast to this, their relations with the Kawaiisu to the north and the Kashtɨq Chumash to the south were said by consultants to have been more peaceful. Tejón Creek Canyon formed part of a major route connecting Kitanemuk settlements on the margin of the San Joaquin Valley with the Antelope Valley. This route ascended the canyon to pass through the original Tejón Pass and descended the upper end of Oak Creek Canyon to connect to variant trails leading down into the Antelope Valley. Harrington's research suggested that the Antelope Valley may have been used seasonally by the Kitanemuk. Consultant Eugenia Mendez thought that Kitanemuks might have lived at Panukavea (Willow Springs). She was also not sure how far north the territory of the Tataviam extended at the west end of the Antelope Valley. Camping places on a major north-south trail descending the southeast slopes of the Tehachapi Mountains on the edge of the Antelope Valley were recalled, as were several major canyons on that mountain face, but Kitanemuk settlements in this area, aside from possibly at Willow Springs, were not. It had traditionally been assumed by archaeologists working in the Antelope Valley that settlements like those on the southwest side of the Valley were of Kitanemuk cultural affiliation (Robinson 1987:11-13). Harrington's Kitanemuk consultants recalled native groups in the Antelope Valley area Archaeological Research Design for the Antelope Valley Study Area 97 07A3822 Task Order 17 that spoke a language similar to Kitanemuk or Serrano. Some statements suggested that these were located towards the south side of the Valley. However, as previously noted, when Fr. Francisco Garcés visited the Antelope Valley in the spring of 1776, his Mojave guides made clear that the Beñemé (Desert Serrano) of the southern Antelope Valley and what Garcés recorded as the Cuabajai (Mojave: "Kuvahaivima"), the Kitanemuk, were separate ethnic entities. When Garcés traveled north across the Antelope Valley en route to a major Kitanemuk settlement in Tejón Canyon, he passed by a spring, apparently Willow Springs, that was not reported as a ranchería site (Coues 1900:I:272-278). This Kitanemuk settlement in Tejon Canyon was known to his Mojave guides due to their traveling to the southern San Joaquin Valley to trade for shell beads and other goods that were carried eastward to the Colorado River. The structure that Garcés describes where his party stopped at this settlement may have been built as a community ceremonial dance house. Although Blackburn and Bean (1978:569) questioned whether the settlement visited was Kitanemuk, there is little doubt that it was. A major feature of the Tehachapi Mountains region was an area of highly productive pinyon woodland in the southwestern portion of the range, overlooking the Antelope Valley on the northwest. Both the Kitanemuk and the neighboring Kashtɨq Chumash exploited this pinyon resource, and Harrington consultants recalled harvesting pinyon there themselves. At lower elevations in the Tehachapi range extensive oak woodland also exists. Complexes of bedrock mortars were still used in Tejón Canyon for processing acorns and other plant foods in historic times. Hard seeds, including chia, were also important for Kitanemuk subsistence. Garcés observed abundant supplies of chia at the settlement he visited (Coues 1900:I:272-273). In the Tehachapi range, deer were hunted, which provided an important exchange item in the form of deer hides. In addition to the hunting of lagomorphs in the foothill areas, ground squirrels were common on the San Joaquin Valley floor and margins and were procured in considerable numbers. Pronghorn antelope were also hunted on the floor of the San Joaquin Valley using drives and corrals. Kitanemuk Social Organization Blackburn and Bean (1978:567) had suggested that a system of patrilineal descent may have existed among the Kitanemuk because of similarities in the kinship terminologies of the Kitanemuk and the Cahuilla, who were patrilineally organized in a manner somewhat similar to the Serrano. However, despite the language link between the Kitanemuk and the Mountain and Desert divisions of the Serrano, the pattern of exogamous localized patrilineal clans or sibs found among the Serrano was not attested for the Kitanemuk by Harrington's Kitanemuk consultants. In the first place, there was no recollection of a moiety system. In addition, exogamous territorial patrilineal clan units per se were not recalled. As Blackburn and Bean (1978:567) stated it, "lineage affiliations do not appear to have been of concern to Harrington's (1986) Kitanemuk informants, and they definitely insisted on the absence of moieties." Political-ceremonial offices took a form familiar among Takic language groups. In addition to the chief (Kika?y), there was a ceremonial manager (Paka?) and several messengers (wana?ypats). The chief presided over funerals and mourning ceremonies, as described below, and over other rituals. Archaeological Research Design for the Antelope Valley Study Area 98 07A3822 Task Order 17 Special ritual paraphernalia are described as having been stored in large baskets rather than in a sacred bundle, as among the Serrano. Garcés' expedition account mentions that the chief of the Kitanemuk community that he visited when entering and leaving the southern San Joaquin Valley had been at war with the Tataviam. Assuming that war leadership was also a function of ritual chiefs, this leadership probably would have been important for Kitanemuk settlements. Both Garcés’ account and Harrington's ethnographic information make it clear that the Kitanemuk had an adversarial relationship with the southern Valley Yokuts (Harrington 1986:III:98:87,89). This was the case despite the fact that the Kitanemuk intermarried with Yokuts groups, as Garcés attested. Given the propensity for aggressive behavior of some of these Yokuts groups, and the upland resources that the Kitanemuk controlled, it is possible that the Kitanemuk settlements may have had to be wellorganized militarily to resist raids by valley groups. Kitanemuk Religious Institutions and Mortuary Customs The Kitanemuk practiced a Winter Solstice ceremony similar to that of the Ventureño Chumash. They also recognized a pantheon of six supernatural culture hero siblings, five male and one female (Kroeber 1925:623; Hudson and Blackburn 1978:226-231). This reflected a religious belief system, associated with a toloache initiation ceremony that was shared by the Kitanemuk with the Yokuts and Gabrielino/Tongva. Kitanemuk consultants emphasized that the “religion of the coast” with sacred enclosures and powerful wizards (both the Gabrielino/Tongva version which featured the deity Chingichnich and the Ventureño Chumash version) did not extend to the territory of the Kitanemuk (Hudson and Blackburn 1978:231). The Kitanemuk traditionally practiced interment rather than cremation. Blackburn and Bean (1978:566-567) describe Kitanemuk mortuary customs and practices. Among the Kitanemuk, like the Chumash, elderly females performed the office of mortician (tɨtɨyɨm). This position was inherited. After death, the body of the deceased person was first taken to the chief's house, where the morticians prepared it. It was tied and placed in a mat and kept in the chief's house during a nightlong ritual of singing mourning songs and weeping. The morticians then carried the body to the cemetery, circling it three times in a counterclockwise direction. While the morticians carried out the work of carrying the corpse, the grave had previously been excavated by men using digging sticks. At the grave, bits of the brain of the deceased were removed from the skull as an act of remembrance, which indicates that interment had traditionally been practiced. At the time of burial, valuables were also put into the grave, and the excavation was then filled. Sometime after the burial, a burning of property of the deceased took place. The Kitanemuk also held mourning ceremonies that contained elements shared with interior southern California groups like the Serrano of the San Bernardino Mountains. This ceremony lasted a week and was held at a special dance enclosure built for the occasion. Because of the expense incurred in hosting a mourning ceremony, a community would only sponsor it every four or five years. Archaeological Research Design for the Antelope Valley Study Area 99 07A3822 Task Order 17 Preparations for the mourning ceremony, the issuing of invitations, and the management of reciprocal relations with those invited, were in the hands of the chief of the host community. In addition to the chief, a paka or ritual assistant, helped to conduct the ceremony. The paka was responsible for taking care of the feeding and housing of ceremony guests. While the invited attendees were fed by the host community during the entire week of the fiesta, the chiefs of the invited groups did bring gifts with them. The host chief displayed the bead wealth of the host community during the ceremony, and this was matched by bead displays of the visiting chiefs. During the final day of the ceremony, a ritual human effigy or tsahira was made by guests invited to the ceremony. This was a common feature of the mourning ceremony among Takic groups in southern California. The effigy or image was later burned along with items donated by members of the host community - baskets, beads, and so on. At this point gifts were also given to the invited guests. At the same time, the chiefs of invited communities selected certain of their followers to wash the ash-covered faces of host community members who had been in mourning. These face washers were later given gifts. Like neighboring groups, the Kitanemuk also used grave poles to honor and commemorate deceased chiefs. This practice was also found among the Chumash and Gabrielino, but not among the interior groups like the Serrano or Cahuilla. A Possible Kitanemuk Settlement in the Antelope Valley- Panukavea or Sesevjek Eugenia Mendez identified the spring at Willow Springs, west of Rosamond, as Panukavea. She stated that she was sure that it was occupied by Serrano-speaking people. She said that the name of the place was derived from the term for "tule reed," and that the people who lived there did in fact eat tule reeds, the roots of which are edible (Harrington 1986:III:98:34,58,675). This place was also referred to as Sesevjek. It is not clear whether people living at this place may have been of Kitanemuk or Desert Serrano affiliation. Alternatively, it may have been a seasonal residential base used by both groups. The Kashtɨq Chumash The Kashtɨq Chumash were an interior Chumash group who were linguistically closely related to the Ventureño Chumash. They were based at the settlement of Kashtiq, located on the north side of Castac Lake in the Tehachapi Mountains near Lebec and about five miles west of the west end of the Antelope Valley. The Kahstiq community formed part of a larger set of interior Chumash communities in the region. These included the Emigdiano Chumash villages of Matap'xwelxwel, at the northern outlet of the Grapevine (modern Tejon Pass) and Ta'cuya, in the next canyon to the west of it, and another Chumash village, Shuxwiyuxus, in Hungry Valley to the southwest of Kashtiq. Thus, Kashtɨq formed part of an exchange corridor linking coastal Ventureño Chumash groups with the Southern Valley Yokuts and groups further to the north and northeast. Chumash Olivella and clamshell beads, along with steatite items and asphaltum, were traded northward from the coast in return for Coso obsidian, deer hides, and pinyon pine nuts (Smith 2002:326; Voegelin 1938:50-51). Archaeological Research Design for the Antelope Valley Study Area 100 07A3822 Task Order 17 The Kashtɨq Chumash probably visited the northwestern Antelope Valley to gather desert resources, traveling from Kashtiq to the Antelope Valley by way of Oso Canyon. This canyon received its name based on the large number of grizzly bears in the area, Oso Canyon also had stands of acornproducing oaks at its upper end. Kashtiq Chumash Settlement and Subsistence The location of Kashtiq was strategic not only in respect to long-distance exchange from the coast to the San Joaquin Valley and the southern Sierras, but also in respect to access to pinyon in the higher altitude uplands of the Tehachapi range. Just to the northeast of Kashtɨq was a southwesterly spur of the Tehachapi Range, known as SipoSipoS in Ventureño or Kashtɨq in Chumash and Tivang in Kitanemuk- meaning "pinyon place". It was a well-known pinyon gathering area, where pine nuts were said to ripen earlier than elsewhere. Due to the high demand for pinyon by other Chumash groups, it was an important exchange item from the southern Sierras and from the Tehachapis towards the Ventura County coast (Voegelin 1938:51-52). Kashtɨq was one of the only interior Chumash settlements with access to a prime pinyon zone. In addition to the exploitation of pinyon, oak groves were found in the vicinity of the Kashtɨq settlement. Chia was harvested in the area, and juniper woodland was also abundant. When this ranchería was visited by Franciscan Father José María Zalvidea in August of 1806, its inhabitants were largely absent gathering juniper berries in the vicinity (Cook 1960). At least some of the population of this community appears to have survived at this or some other location through the 1840s, since three ‘chiefs’ of the native people of ‘Castake’ signed a treaty with U.S. government representatives in 1851 (Heizer 1972:39). Kashtiq Chumash Social Organization For coastal Chumash groups, living in large communities, information on marriage has suggested that post marital residence was uxorolocal - living in the wife's community. This in turn has suggested to Johnson (1988) that the coastal Chumash may have had matrilineal descent groups. Harrington’s Ynezeño Chumash consultant María Solares recalled a system of apparently nonlocalized patrilineal clans (Harrington 1986:III:7:54-55,270). Social organization in the interior was affected both by smaller village sizes and bicultural contact with neighboring groups like the different Southern Valley Yokuts groups. Some interior villages may have had populations of over 100 people, and others less. Reports of houses used in interior communities further to the west from Kashtiq and San Emigdio indicate that these were also large, and that interior villages also featured sweat lodges, dance floors, and cemeteries. Franciscan mission baptismal data indicate that Chumash interior villages were headed by hereditary chiefs. Whether villages were organized into a single social group, or whether there were subsidiary kin groups, is not known. Archaeological Research Design for the Antelope Valley Study Area 101 07A3822 Task Order 17 Kashtiq Chumash Religious Institutions and Mortuary Customs Interior Chumash areas, including the Carrizo Plain, to the northwest of San Emigdio, are famous for their rock art, including elaborate polychrome paintings apparently done in recent centuries. This art provides a strong connection to the religious traditions and expressions of coastal Chumash people. The Ventureño Chumash and other coastal groups were involved in the 'Antap cult, which involved initiation of ritual adepts into the cult. This cult has suggested a degree of social differentiation in coastal Chumash society, with members of the cult enjoying special social and ritual status. This cult was thought of by Harrington's Kitanemuk consultants as a coastal phenomenon, despite the fact that the Ventureño themselves considered Mt. Pinos and Cuddy Valley, just to the west of Kashtɨq Chumash territory, as a sacred center for this cult. It was associated with other elements of Chumash religion, including the hutash harvest fiesta, and winter solstice rituals. It is known that shrines and prayer banners were found in the interior, along with impressive rock art (Mikkelsen et al. 2014:4748). Harrington’s Kitanemuk Consultants mentioned that this coastal cult or religion was found among the Kashtiq Chumash (Hudson and Blackburn 1978:231). The Chumash in the interior established cemeteries close to their villages, as did those on the coast (Benson 1997:182-206). Like villages on the coast, they practiced inhumation. Like the Kitanemuk, the Chumash employed special elderly female undertakers. In both the coast and the interior, it was customary to place grave poles, with baskets that commemorated the dead of either gender. Cemetery fencing and grave marker slabs and grave coverings of large cobbles are also reported for coastal cemeteries. Attempts by coyotes in all areas and by bears in the interior to disturb graves were discouraged by grave coverings and by placing cemeteries next to village sites. Objects buried with the dead included steatite and other stone bowls, shell and steatite beads, sweat scrapers, deer bone flutes, and tobacco pipes (Bernard 2008:39). As was the case elsewhere in Southern California, both coastal and interior Chumash groups held periodic mourning ceremonies, that included not only burning the possessions of the deceased, but commemorative offerings of valuables by relatives to be destroyed. In post-mission times in the nineteenth century, the mourning ceremony was sometimes combined with the autumn harvest fiesta, that honored hutash, the female earth deity. The Kawaiisu (Nüwa) The Kawaiisu (Nüwa) are a group in the Numic branch of the Uto-Aztecan language family that formerly occupied mountain and desert territories both to the northwest and north of the Antelope Valley. The Kawaiisu are closely linked linguistically to the Chemehuevi/ Southern Paiute of eastern California and Southern Nevada. In late prehistoric times they are presumed to have abandoned a desert foraging way of life in favor of the exploitation of acorns and pinyon in the relatively highaltitude areas of the Tehachapi region. Archaeological Research Design for the Antelope Valley Study Area 102 07A3822 Task Order 17 Kawaiisu (Nüwa) Settlement and Subsistence Garcés' diary of 1776 and later ethnographic information collected by Harrington (1986:III:98:664670) and Zigmond (1986) indicate that the Kawaiisu of the Tehachapi and southern Sierra regions were living in the area between Walker Pass and Kelso Creek in the north and Tehachapi and Brite's Valley in the south at the time of Spanish contact (Garfinkel and Williams 2011:23-68). Garcés encountered a ranchería inhabited by Kawaiisu women and children, apparently somewhere in the west center of the Tehachapi Valley (Coues 1900:I:304-305). He indicated that the Kawaiisu, wellknown to his Mojave guides, were involved at that time in long-distance trade with other groups. This group was noted for its production of wild tobacco, which was an important exchange item. In fact, an east-west route passing through the Tehachapi Valley was used by Mojave traders traveling to the San Joaquin Valley from the direction of the Colorado River. The Kawaiisu traditional gathering territory ranged eastward across the Mojave Desert through the northern part of the Antelope Valley Study Area to the vicinity of modern Fort Irwin. Mojave Desert camps were maintained by the Kawaiisu, as has been documented by Steward (1938) and Earle (2004b). This use of the desert included the exploitation of desert lake salt deposits. It is also considered likely that areas on the northern side of the Antelope Valley, including within Edwards Air Force Base, were at least intermittently used by the Kawaiisu. Information from Kawaiisu elder Andy Greene (1995) indicates that mesquite in the Edwards Air Force Base area was traditionally exploited by Kawaiisu. The Tehachapi region of Kawaiisu territory was more xeric on the desert side and more mesic on the San Joaquin Valley side. Western portions of Kawaiisu territory featured vast oak woodland areas, such as at Comanche Point or on upper Caliente Creek. More easterly upland areas produced pinyon pine nuts. These mesic conditions were often found in areas of relatively high altitude - the Tehachapi Valley, for example, lies at an altitude of around 3,900 feet. Thus, winter climate conditions for Kawaiisu villages were more extreme than was typical for most southern California groups. Kawaiisu (Nüwa) Social Organization Like the Kitanemuk, Kawaiisu ethnographic consultants did not emphasize the existence of unilineal kin groups. In historic times, at least, community leadership appeared to emphasize more of a 'bigman' style informal leadership than the inheritance of hereditary office. The ethnohistorical record, however, suggests that powerful chiefs may have existed during the era of Spanish rule. A chief named Quipagui (Kepawish), based at the settlement of Akutuspea, was famous in Southern California during the period from 1800 through 1820 for harboring native runaways from the Franciscan missions (Palomares 1808). He also defeated at least one Spanish military attempt to capture him (Palomares 1808). It is not clear whether the Kawaiisu may have formerly possessed a system where hunting territories and hunting songs were inherited through the male line, as was apparently the case among the closely related Chemehuevi. Laird (1976) has described such a system of what she called ‘song groups’ among the Chemehuevi. Archaeological Research Design for the Antelope Valley Study Area 103 07A3822 Task Order 17 Kawaiisu (Nüwa) Mortuary Practices Kawaiisu mortuary practices appear similar to those of the Chemehuevi and Southern Paiute in many respects. Zigmond notes that the body of a deceased was wrapped in a tule reed mat, then was usually placed in a rock cleft or hollow and covered with a split burden basket (Zigmond 1986:404). As with the Chemehuevi, sacred stories of the Kawaiisu specify the covering of the dead with the burden basket (Zigmond 1980:18). The body and basket were then covered with rocks. This was said to have been performed on the same day as the death. The deceased's house was burned. Personal property might be either interred with the dead, burned, or abandoned. Some property might also be retained by relatives or friends, according to Zigmond. He also notes that relatives of the dead marked the death by abstaining from face washing, burning off their hair, and carrying out mourning wailing during the morning and evening. The places where bodies were buried were considered dangerous and were avoided. The interred property of the dead was apparently occasionally found disinterred, and was avoided, as were human bones. The Kawaiisu celebrated a mourning ceremony in a ceremonial enclosure on an intermittent basis. In historic times a fire was built in the enclosure, and special funerary images of the deceased being commemorated were burned in the fire. The images were made of clothing of the deceased placed over a brush and bark framework. The burning of the images was followed by a night of dancing. The Chemehuevi The Chemehuevi can be considered a southwesterly branch or division of the Southern Paiute of the Numic branch of the Uto-Aztecan language family (Earle 2004a; Kelly and Fowler 1986). They were linguistically closely related to the Kawaiisu of the Tehachapi Valley and Piute Mountain regions and shared some other features of culture with them. The Chemehuevi originally occupied areas of the eastern Mojave Desert. After 1830 small groups of Chemehuevi moved into the Western Mojave Desert, including the Antelope Valley and the San Gabriel Mountains, after the removal of many residents of Serrano-speaking communities on the Mojave River and elsewhere to the Franciscan missions. The Chemehuevi were present first as seasonal stock raiders and later as more permanent family groups carrying out hunting and foraging. Traditional Chemehuevi Settlement and Subsistence As of the late eighteenth century, the Chemehuevi occupied areas of the eastern Mojave Desert around the Kingston, New York, and Providence Mountains. They also ranged in the desert west of the Colorado River further south. This territory extended southward from the basin and range areas west of Mojave territory in the Mohave Valley at Needles to the desert region west of the Palo Verde Valley and east of the Little San Bernardino Mountains. In their original home territory, the Chemehuevi exploited agave, yucca, pinyon, and juniper in upland areas and mesquite and screwbean groves on desert floor lake playas. Grass seeds such as Oryzopsis Archaeological Research Design for the Antelope Valley Study Area 104 07A3822 Task Order 17 and the Lyceum berry were found at lower altitudes. Carrizo grass (Phragmites) and its aphid sugar were found around springs. They hunted desert bighorn, pronghorn, deer, jackrabbits, cottontail, chuckwalla, and the desert tortoise (Laird 1976, 1984). Chemehuevi Social Organization The Chemehuevi have traditionally been viewed as having a relatively simple social organization without clans or other descent groups, such as are found among the Serrano or Cahuilla. Mobile local residential groups, the niwiavi, were thought to be based on the bilateral kindred, the noncorporate and 'double descent' kind of family unit found among the Inuit Eskimo or in modern EuroAmerican society. However, the field research of Harrington, Carobeth Laird, and the testimony of Laird's Chemehuevi husband, George Laird, revealed a different social organization (Laird 1976:8-29, 1984). The Chemehuevi traditionally had at least two supernaturally sanctioned categories of descent groups associated with hunting. These were what were called 'song groups', associated with a specific supernatural animal - deer or mountain sheep - as a sort of totem. The niwiavi, on the other hand, were not fixed, but moved around the landscape. When Chemehuevi men married, they usually would move to the niwiavi of their spouse. This meant that groups of unrelated men from different song groups resided in the same niwiavi with their wives. This was a great advantage, because the men of the niwaivi group would share access to a number of different fixed hunting territories, and the mobile niwaivi group could move or rotate through them. Men shared access to these hunting territories with each other, because hunting was a group activity and men could not hunt alone. The Chemehuevi Diaspora After 1828, some Chemehuevi moved into the Colorado River valley below the Mohave Valley, to become floodwater farmers, after the Mojaves had dislodged the Halchidhoma from the Colorado River around Blythe. Other Chemehuevi groups gradually dispersed across interior Southern California, as far west as the Antelope Valley and as far south as the Coachella Valley, Yuma, and San Diego County. Between 1830 and 1870, some parties of Chemehuevi were involved in stealing stock from ranchos, and even fighting other Native Americans living closer to the coast. Other groups combined seasonal wage work with the annual round of foraging and hunting, particularly from around 1865 onward. They also intermarried with other native groups in the Southern California interior. When the Chemehuevi occupied the Mojave River area and the Antelope Valley in the nineteenth century, they filled a void left by the removal of Serrano and other people to the missions during the period 1800-1830 (Brooks 1977). The Chemehuevi hunting culture reflected the great challenges posed by hunting in the driest portions of the Mojave Desert. It is thus not surprising that with the changed conditions after 1830, the Chemehuevi explored different options for increasing their food security. These options included not only Colorado River farming, but movement into new areas closer to the coast, including the San Gabriel Mountains, where game was more abundant. In the Mojave River and Antelope Valley regions, deer, pronghorn, and desert bighorn (mountain sheep) hunting was combined with other traditional hunting regimes - jackrabbits, rodents, chuckwalla, desert tortoise, and quail. The gathering of seeds was supplemented with the exploitation of single leaf pinyon Archaeological Research Design for the Antelope Valley Study Area 105 07A3822 Task Order 17 and juniper berries. One group encountered living in the San Gabriel Mountains in circa 1880 was also processing acorns and hunting grizzly bears (Vernon 1956:144). This reflected the remarkable and well documented cultural flexibility of the Chemehuevi in taking advantage of new opportunities within their traditional way of life (Roth 1977). At valley floor and foothill spring sites in the Antelope Valley, an overlay of Chemehuevi occupation in the nineteenth century may be manifested archaeologically. Many localities in the areas were visited or occupied by Chemehuevi, including Rosamond, Red Hill, Rogers Dry Lake, Lovejoy Springs, Pallett Creek, Barrel Springs, Vincent, Elizabeth Lake, and Mescal Creek (Gordon 1990:4, 88; Morris n.d.:66-73). One of the last Chemehuevi settlements in the Antelope Valley was occupied in the hills directly south of Palmdale as late as 1890. Remnants of a hemispherical framework of juniper poles for a thatched dwelling were recovered there in 1964 (Rozaire 1990). Chemehuevi Mortuary Customs Like other California groups, the Chemehuevi held periodic mourning ceremonies to honor and commemorate the dead of the community since the last ceremony (Earle 2009b:65-69). These were usually held in autumn, when pinyon or other food resources were most abundant. Due to their wide dispersal across the desert, individual Chemehuevi niwaivi received invitations to a mourning ceremony accompanied by mnemonic calendar devices indicating the date at which a mourning ceremony would be held. Such gatherings were presided over by regional chiefs. The documentation of traditional practices related to funeral customs and mourning ceremonies among the Chemehuevi has involved some uncertainty about the practice of cremation or interment (Earle 2009b:66-68). A review of ethnographic reports suggests that interment was the usual practice. As was the case elsewhere in southern California, personal property of the deceased was destroyed at the funeral, as was the dwelling. After the completion of the mourning ceremony, a person could not mention or be asked about a deceased relative (Laird 1976:53-54). Similar to the Mojave, Serrano, and Luiseño, the Chemehuevi used a complex series of sacred songs involving the recitation of supernatural travel across the desert landscape as part of the mourning ceremony (Earle 2009b:68-69). These songs identified sacred places on the landscape and stories from the time of creation that were associated with them. Among the sacred places of the Chemehuevi were springs, believed to be the abode of supernatural beings that could travel under the earth from one spring to another (Fowler 2002). Trails were also associated with the supernatural, and Chemehuevi culture emphasized the art of long-distance and high-speed desert travel (Fowler 2004). Not only were special runners employed to communicate across the desert, but it was believed that runners could have supernatural powers that would permit them to travel great distances very rapidly. As in many other respects, the Chemehuevi had thoroughly adapted their travel to the challenges of the xeric desert environment. Archaeological Research Design for the Antelope Valley Study Area 106 07A3822 Task Order 17 History of Native/Non-Native Relations in the Antelope Valley Mission Period (1769-1835) During Spanish colonial rule, the Antelope Valley remained beyond the limits of Spanish settlement and regular administrative control. During both the Spanish and Mexican periods, transit of the mountain passes into the Mojave Desert was believed to lead to an extremely unattractive and dangerous wasteland. Interest in mining in the desert had not yet developed. The Antelope Valley region was first visited by a European in 1772, when Capt. Pedro Fages passed across the southern Antelope Valley from east to west while on an expedition in search of deserters (Bolton 1935). He mentioned seeing villages in the valley and stopped at a native community at Lake Hughes on the southwest margin of the valley. Four years later, in April of 1776, Fr. Francisco Garcés crossed the western Antelope Valley from south to north (Coues 1900:268-272). A month later he returned from the southern San Joaquin Valley and passed from west to east, apparently within sight of Rosamond and Rogers Dry Lakes on what is now Edwards Air Force Base (Coues 1900:305-306). Garcés had attempted to find an interior route from Sonora and Arizona to Monterey in California, but his effort was not successful. Following these visits, we have no documentary record of Spanish visitors to the area until 1806. In that year a Spanish military expedition accompanied by Franciscan priest Fr. José María Zalvidea passed southeastward from the Gorman area into the southern Antelope Valley, following the desert margin at the base of the San Gabriel Mountains and San Bernardino Mountains, eventually reaching the Mojave River (Cook 1960:247). Zalvidea mentioned seeing native settlements, possibly camps, in the vicinity of modern Littlerock and Pearblossom. Two years later, in 1808, Sgt. José Palomares led two forays through the Antelope Valley with the objective of capturing native neophytes who had fled from Mission San Fernando (Cook 1960:256-257; Palomares 1808). The first foray also had the objective of capturing a Kawaiisu chief in the Tehachapi Mountains who was sheltering runaways. The route of the first foray passed from Kwarung [‘Qariniga’], a native village at Lake Hughes, northward across the western Antelope Valley to the Tehachapi Mountains. This expedition was unsuccessful. A month later, Palomares marched from west to east along the southern edge of the Antelope Valley, visiting several villages, before reaching the Mojave River at the village of Atongaibit. At nearby Guapiabit, he unsuccessfully attempted to recover additional runaways. Villages on the southwest margin of the Antelope Valley like Puning and Chivung appear in the baptismal registers of Mission San Fernando in only a few entries during the decade 1801-1810 (Huntington Library 2006). Sgt. Palomares visited with the chief of Kwarung in the fall of 1808, and native people from Mission San Fernando had been in contact with this village, but mission registers indicate its inhabitants were not joining the mission, before or after this date. In addition, villages in the southern Antelope Valley were reportedly harboring neophyte runaways. Archaeological Research Design for the Antelope Valley Study Area 107 07A3822 Task Order 17 The runaway situation may have become more serious with the arrival of Fr. Zalvidea at Mission San Gabriel, after his desert expedition, in 1806. Zalvidea developed a reputation for cruelty (Dakin 1939:270-275). He was highly dissatisfied with the rate of recruitment of Serranos and other native groups, both in the vicinity of Mission San Gabriel and in more remote areas. He complained that native people were willing to have their children baptized in order to receive gifts from the Franciscan priests, but they themselves were not anxious to join the missions (Geiger and Meighan 1976:129). In the Los Angeles region, a non-mission ranching economy was slowly developing, and native people preferred in many cases to work for ranch owners rather than becoming members of the mission communities. Zalvidea apparently took a more rigorous approach to managing native people at Mission San Gabriel and to hunting down runaways. In any regard, a revolt took place at Mission San Gabriel in November of 1810 (Earle 2005:18-21). This included an effort by Serrano chiefs who had not yet been missionized to enlist the help of the Chemehuevi and a band of some 600 Mojave warriors from the Colorado River, who almost made it to Mission San Gabriel to participate in the proceedings. The revolt attempt was eventually brought to a halt by Spanish military reinforcements. As a consequence, a number of military expeditions were undertaken in 1811, on the Mojave River and in the Antelope Valley, to curb the independent chiefs and apparently to round up fresh converts. Given that in 1811 significant percentages of the total populations of some villages arrived en masse at Missions San Fernando and San Gabriel to be baptized, it is surmised that the military used force to bring them in. Much of the population of the villages of Cuechaong and Chivung in the southwestern Antelope Valley were taken to Mission San Fernando in the spring of 1811 (Huntington Library 2006). The inhabitants of other villages, Maviayek and Kwarung, for example, did not show up at Mission San Fernando, and may have remained in place during the decade of the teens. These two villages were referred to by name by Sgt. Palomares in 1808, but they have not been located under these names in the records of Missions San Fernando or San Gabriel. During the years after 1810, as Franciscan mission recruitment increased, the missions entered a period of crisis on account of the Wars of Independence in Mexico (Earle 1997). Subsidies for the missions were cut off and plans for expanding the mission system into the San Joaquin Valley were shelved. In consequence, native people in the missions were forced to work harder to provide supplies for the military and for civilian settlers (Cutter 1995). An expansion of the southern California mission populations and livestock herds during 1805-1815 lead to an increase in the neophyte death rate at the missions, possibly due to crowding and livestock diseases. Eventually it became difficult to find new converts to replace them, which in turn led to more discontent and more runaways. In February of 1820, Fr. Payeras, Father President of the Alta California Franciscan Missions, officially informed his Franciscan superiors in Mexico City about the “horrible and unusual mortality among the Indians” at the missions that had created population disaster for California’s native people (Cutter 1995:225-228). He said, “…where we have not penetrated, as is the case of the frontier of the tulares and on the adjacent islands before conquest, all of that area is fully populated, while the field or vineyard where we labor [the missions] is depopulated” (Cutter 1995:227). He noted that there had Archaeological Research Design for the Antelope Valley Study Area 108 07A3822 Task Order 17 been only two significant epidemics, dolor de costado [typhoid fever] in 1801, and measles in 1806; so it was due to other factors that the priests would baptize the natives, administer the sacraments, and then bury them, as he put it. In 1816 and 1819 military expeditions were made down the Mojave River (Earle 2010b). By 1819, surviving Desert Serranos on the Mojave River were caught in the middle of a conflict between hostile Mojaves from the Colorado River and their runaway ex-neophyte allies and the Spanish. The Spanish feared raids from the direction of the desert by both the Mojaves and the Desert Cahuilla. Nevertheless, some Desert Serranos remained on the Mojave River in the late 1820s, and a few even later. Mexican Period (1835-1848) Mexico had become independent of Spain in September of 1821, and Alta California recognized the new regime in the spring of 1822, a development that stunned the Franciscan missionaries (Cutter 1995:319). Independence fostered the local hide and tallow trade with foreign merchants, the consequent expansion of non-mission ranchos, and brought political pressure to turn mission lands and labor over to the rancheros. The missions were closed by the Mexican government circa 1835. Stock-raiding from the direction of the southern San Joaquin Valley and the Antelope Valley increased, as did native flight from the Southern California missions (Phillips 1993). In 1824, Chumash at Missions La Purisima, Santa Ynez, and Santa Barbara joined a native revolt that involved Chumash fleeing to Tulamniu at Buena Vista Lake in the southern San Joaquin Valley (Blackburn 1975; Earle 2003). Southern Valley Yokuts chiefs had sheltered mission runaways and participated in the revolt. Some Mexican troops sent to Buena Vista Lake to retrieve the runaways had apparently passed by way of the west end of the Antelope Valley. From the 1820s through the 1840s the Antelope Valley remained beyond the limit of non-native settlement, despite the expansion of ranching nearer to the coast. In 1826, steps were taken to emancipate mission neophytes, and in 1833 a Mexican legislative decree called for the secularization of mission lands, although this process was not immediate (Bancroft 1885:100-107, 339-357). With few exceptions, these lands were acquired by rancheros rather than native neophytes. In 1826 the first Euro-American trappers reached southern California, later passing through the southern Antelope Valley en route to the San Joaquin Valley (Earle 2005). Beginning in 1829-1830, the so-called Old Spanish Trail, connecting Santa Fe, New Mexico with Los Angeles via the Mojave River, was inaugurated. New Mexican traders herding California horses and mules back to New Mexico were glad to purchase stolen stock from native groups in the southern San Joaquin Valley and the Mojave Desert (Phillips 1993:102-103). Along with native stock raiding, there were also occasional raids by Euro-American trappers allied with Utes from Utah. By the 1820s and 1830s, a small number of residents of Kitanemuk and Kawaiisu communities in the Tehachapis had also been baptized at Mission San Fernando (Earle 2011:71-72; Huntington Library Archaeological Research Design for the Antelope Valley Study Area 109 07A3822 Task Order 17 2006). Native accounts of movement of people to that mission from Kitanemuk territory do not appear to jibe completely with baptismal records, so some such individuals or families may have been resident in the mission region without having been baptized. In respect to the possible movement of surviving native families living in the Antelope Valley region, it is to be kept in mind that during the 1820s and 1830s the expansion of the non-mission ranching economy in the Los Angeles region brought seasonal and longer term native labor migration from more distant communities that had not been completely missionized (Earle 1997). There are hints of military or ranchero raids against suspected stock-raiders in the Antelope Valley and the Tehachapi Mountains between 1825 and 1845 (Barras 1984:9; Jackson and Spence 1970:670). As the size of the Mexican military establishment in California declined, rancheros themselves conducted raids across the frontier. These sometimes involved bringing back native captives as forced labor. There also appear to have been some native families living on the southwestern edge of the Antelope Valley, at Hwit' Ahovea and Cuechaong at Liebre Mountain and around Elizabeth Lake, in the 1830s or 1840s. In the case of Cuechaong, at least a few former residents had returned from Mission San Fernando to re-occupy the place after 1830 (Johnson and Earle 1994:201). In the spring of 1844 when John Frémont passed through the southern Antelope Valley, he saw no native people (Jackson and Spence 1970:670-674). It is presumed that the trans-desert traffic of armed outsiders - Chemehuevi/Southern Paiute stock raiders, as well as native stock raiders from the Eastern Sierra and the Great Basin, occasional New Mexican traders, and rancheros and military parties attempting to suppress the raiding - made it imperative for any native families in the area (or returning to the area) to keep a low profile. However, native people were living in the Tehachapi region, and they told Fremont about Mojave bead traders who were still traveling from the Colorado River to the Tehachapi region to trade for shell beads. These traders were noted as following a trail along the south side of the Antelope Valley in traveling from the Mojave River to the Tehachapi Mountains (Jackson and Spence 1970:667). Chemehuevi/Southern Paiute family groups from the east were first observed establishing camps on the Mojave River in the late 1820s (Earle 2005:24). By the early 1840s they were raiding down into the current Los Angeles basin and Orange County areas from the adjacent desert. For almost all of the remainder of the nineteenth century they would have a presence in the Antelope Valley or its margins. In the modern San Bernardino region, both non-mission Serranos and mission survivors were present in the 1840s and before, and they had both friendly and armed encounters with Chemehuevi/Southern Paiute parties visiting that area (Harrington 1986:III:101:178). By the end of Mexican rule in 1848, efforts were made to establish (or assign) grazing rancho grants around the west end of the Antelope Valley and in the southern San Joaquin Valley. A portion of the Santa Clarita Valley had been occupied by Rancho San Francisco, originally a Mission San Fernando rancho, for decades, but as of 1846 the grants further north existed on paper only. Nevertheless, some Hispanic traffic and presence beyond the transverse range frontier is suggested by the recollections of Tejon Ranch foreman Jose Jesus Lopez, whose father had been a mayordomo at Archaeological Research Design for the Antelope Valley Study Area 110 07A3822 Task Order 17 Mission San Fernando. He recalled that in the early 1840s small Hispanic farming settlements existed at San Emigdio Canyon, west of the current Grapevine, and on the south shore of Kern Lake in the southern San Joaquin Valley. His grandfather and father both made carreta journeys from San Fernando via San Francisquito Canyon and the Antelope Valley to reach the southern San Joaquin Valley in the 1840s (Latta 1976:57,59,61). This route was called ‘El Camino Viejo’ by Lopez, and he recalled that it long predated its use as a wagon road by American pioneers in the 1850s. By the 1850s, efforts were made to utilize the Mexican land grants in the area, which became components of the vast Tejon Ranch that was being run by Edward Beale as of the 1860s. American Period (1848-Present) By the Gold Rush era at the beginning of the American Period, the Tejon Canyon region in Kitanemuk territory had attracted native families from surrounding regions. The Pacific Railroad Survey visited the Tejon region in 1853 and observed this and nearby native settlements (Blake 1856:38-41). Families were living in traditional native-style hemispherical dwellings- jacales - and were carrying out a mix of Mexican-style gardening and traditional foraging. Native settlement was somewhat 'camouflaged' in locations not likely to be visited by outsiders. In this Gold Rush era, throughout southern and central California, travel was dangerous, as the state was infested with lawless characters of both local and foreign origin. In 1851, a treaty was signed between locally resident native groups in the Tejon region, along with southern Valley Yokuts groups from further afield, and the U.S. Government (Heizer 1972). Native representatives of the Kastiq Chumash, the Tejon Rancheria (at least partly Kitanemuk), and the Interior Chumash settlements of San Emigdio and Grapevine Canyon signed the treaty (Heizer 1972:39). The treaty was never ratified due to opposition by California's senators. In 1853, the Sebastian Reserve was established to the south of Tejon Canyon and the following year a U.S. Army post, Fort Tejon, was set up in Grapevine Canyon at the southern end of the San Joaquin Valley (Blake 1856:39; Williamson 1856:21). New residents of the Sebastian Reserve in 1854 included a group from northern Tataviam territory under a chief named Estanislao, born at Tochonanga (Newhall), but married to a woman from Cuechaong at Liebre Mountain. Under him was another chief, Clemente, said to be from Elizabeth Lake on the southwest margin of the Antelope Valley. This suggests that Clemente led his own contingent. The total population under these chiefs was listed as 100 (Giffen and Woodward 1942:30). These men had apparently previously worked on a ranch in the Santa Clarita basin, perhaps as shepherds. Clemente appears to have been baptized as an infant at Mission San Gabriel in November of 1823, and to have been of Desert Serrano affiliation (Huntington Library 2006). His parents were brought to Mission San Fernando in the spring of 1811 from the Desert Serrano village of Chivung, located near Elizabeth Lake. He and his group, like that of Estanislao, were at least partially returnees or refugees from Mission San Fernando. Estanislao’s group is known to have settled at a place called Poxwi, at the mouth of Pastoría Creek, to the south of the Tejon Ranchería in the southern San Joaquin Valley foothills (Johnson and Earle 1994:205). Archaeological Research Design for the Antelope Valley Study Area 111 07A3822 Task Order 17 The first permanent non-native settlement in the Antelope Valley consisted of herders at Elizabeth Lake and was present by 1854. Later, a mostly Hispanic settlement developed at this lake. The Antelope Valley briefly formed part of the Overland Stage route in California in the years immediately before the Civil War. By the end of the Civil War, Fort Tejon had been abandoned, and Edward Beale absorbed some of the population of the Sebastian Reserve, also abandoned, into his Tejon Ranch, which also included the Tejon Ranchería (Latta 1976:191-195). After the Civil War, southern cattlemen settled in portions of the Antelope Valley, while the west end was used by the Tejon Ranch and Liebre Ranch. After the Southern Pacific Railroad from San Francisco to Los Angeles was built through the Antelope Valley in 1876, farming settlement and the first attempts at irrigation occurred in the 1880s (Earle 2004a, 2004b). During these decades, the native population of the Antelope Valley consisted mostly of Chemehuevi/Southern Paiute families coming and going, in later decades mixed with Kawaiisu in the Tehachapi area, with a few people of Serrano origin included as well. A mixed group of Chemehuevi and Serrano was reported living in the Valyermo area on Big Rock Creek as late as 1890. A second group lived at the Pallett Ranch, just west of Big Rock Creek, and later on the Mathis Ranch in the Littlerock area in the mid-1880s (Morris n.d.:63, 76). These groups were recalled as occupying native camps but may have performed casual labor for ranchers. Other Chemehuevi or mixed Chemehuevi and Kawaiisu family groups were living at both desert springs and on the south side of the Antelope Valley in small traditional camps. These groups tended to live in traditional dwellings and follow a traditional subsistence regime. They could be found as late as the decade of the 1890s, which ended with a severe drought that prompted the building of the Los Angeles aqueduct across the west end of the Antelope Valley. Some of these groups had moved to Victorville by 1905, when they were interviewed by Alfred Kroeber (1925:602). During the early 20th century, native presence in the Antelope Valley appears to have been limited to individuals or single families at different points in time. Archaeological Research Design for the Antelope Valley Study Area 112 07A3822 Task Order 17 RESEARCH CONTEXT Archaeological Research Design for the Antelope Valley Study Area 113 07A3822 Task Order 17 Theoretical Orientation In this section, relevant concepts and theoretical frameworks for guiding archaeological research in the Antelope Valley are presented. Relevant concepts include culture, social relations, collectors and foragers, travelers and processors, storage and sedentism, and intensification. Theoretical frameworks include cultural materialism, cultural ecology, optimal foraging theory, evolutionary archaeology, human behavioral ecology, cultural transmission, landscape archaeology, and indigenous archaeology. Although the concepts and theoretical frameworks could be discussed in separate sections, they are instead discussed in the approximate order in which they were adopted by archaeologists because the discussions of later concepts and theoretical frameworks build on those of the earlier ones. Culture The concept of culture provides a unifying theme for the four fields of anthropology, including archaeology. Archaeologists have employed two concepts of culture, the normative approach and a view of culture as a means of adaptation to the environment. The "normative" approach to culture is characterized by the view that culture is “shared ideas” about how things should be done and how people should behave. People who participate in the same culture have similar ideas about how a house should be built, how a pot should be decorated, or how religious ceremonies should be conducted. Because culture is ideational, culture is manifested in the physical world through behavior and artifacts. Culture historians use the normative concept of culture to define archaeological cultures on the basis of ideational unity reflected in the stylistic relationships among artifacts (Dunnell 1978). One criticism of normative definitions of culture is that the approach implies homogeneity and thus underplays or obscures variation within a society. Adopting a normative definition of culture leads to emphasis on "typical" stylistic characteristics rather than on functional variability which may be a product of adaptation to variations in the environment. Archaeologists who are culture historians tend to use stylistic types to define a cultural pattern for a particular time period. They construct a temporal sequence of typical cultural patterns based on stylistic types, but they cannot explain how one cultural pattern changed to another or how a cultural pattern interacted with its environment. The normative approach provides a more descriptive, static, and ideal definition of culture. The normative view does not, however, point so explicitly to the major function of culture as an adaptive strategy for man's existence. Cultural reconstructionists have used the concept of culture as an adaptive strategy through which a group of people interacts with their environment (Dunnell 1978). Adaptation is the ability of a Archaeological Research Design for the Antelope Valley Study Area 114 07A3822 Task Order 17 cultural system to react to their environment in a way that is favorable to the continued operation of the system (Kirch 1980). Cultures adapt in response to the conditions of a culture’s social and biophysical environment. Cultures which fail to adapt to change will eventually die out, while societies effective at adaptation will survive. Binford (1965:205) defined culture as man's extrasomatic means of adaptation. Culture is an adaptive system composed of subsystems, and the cultural system is employed in the integration of a society with its natural environment and other sociocultural systems. Binford (1965:205) writes: In cultural systems, people, things and places are components in a field that consists of environmental and sociocultural subsystems, and the locus of cultural process is in the dynamic articulations of these sub-systems. The concept of culture as an adaptive system that includes both human behavior and the environment is more useful to archaeologists with a materialist orientation, but it ignores human agency. The assumption that a specific culture has adapted to its environment emphasizes stability and equilibrium and makes it difficult to investigate change and variation. Cultural Materialism Cultural materialism has a general and a specific meaning. In its general form it is a research strategy which emphasizes the material, as opposed to the mental or ideational, components of human behavior. In a materialist research strategy, the interactions of environment, technology, group size, and labor are assumed to be the most important determinants of group organization. Cultural materialism can be a productive strategy for formulating research questions which can be addressed with archaeological data. Such data consist of tools used to procure and process food and carry out other tasks in which members of groups interact with the environment. Information about the environment is available from faunal and floral remains found in archaeological sites. Data relevant to the reconstruction of activities and group size come from the spatial distribution of artifacts and features (facilities such as hearths, storage pits, and house post holes or foundations). A specific form of cultural materialism is the strategy for understanding the causes of similarities and differences among societies and cultures that was articulated by Marvin Harris (1979, 1987). Harris' cultural materialism is based on the assertion by Marx that the mode of production and other material processes largely determine other aspects of society and culture. In Harris' research strategy, cultural materialism identifies the independent and dependent variables among the various conditions of the human experience in order to formulate questions about the causes of sociocultural phenomena. The independent variables are considered to be the material aspects of human existence which include food production and regulation of population size. Description of the basic strategy is facilitated by reference to the "universal pattern" which partitions culture into three parts - infrastructure, structure, and superstructure (Harris 1987:17). Archaeological Research Design for the Antelope Valley Study Area 115 07A3822 Task Order 17 Infrastructure includes modes of production and reproduction. Mode of production includes subsistence systems, the articulation of a people's technology with their bio-physical environment to meet food requirements. Mode of reproduction refers to the regulation of population size and includes the costs and benefits of raising children in particular techno-economic and technoenvironmental settings. Structure refers to the organization of domestic economies and political economies. Goods and services are controlled either within domestic units, such as families, between groups within the larger society, or between societies, hence "political economy." Important aspects of political economy include the economic integrative factors which describe types of exchange (reciprocity, redistribution, barter, price market exchange), types of money (all-purpose or non-all-purpose money), and long-distance trade models. Superstructure includes the non-material aspects of culture. World view, or ideology (e.g., religion, magic, political philosophy), artistic expression, and play are components of superstructure. According to Harris, ideologies, including religion, may help rationalize or justify economic systems and political institutions. Cultural materialism gives primacy to the material conditions of life in formulating research questions. In terms of the categories in the universal pattern, Harris (1979:56) proposes the principle of infrastructural determinism. This principle means that when formulating theories and hypotheses to be tested, infrastructural variables are assumed to be independent and causal. Only if hypotheses involving infrastructural variables cannot be confirmed is explanation sought among structural variables, and even less priority is given to superstructural variables. However, some amount of reciprocal causality is acknowledged for the dynamics among infrastructure, structure, and superstructure. Cultural materialists assume that material conditions control the selective process in significant culture change. From a materialist viewpoint, if ideas are to be of long-term importance, they must undergo a selective process through material manifestations or consequences of the ideas. Cultural Ecology Most archaeological cultural reconstruction as defined by Dunnell (1978) has been based on cultural ecology and ecological anthropology. Cultural ecology was first defined by Julian Steward (1955), to understand the interactions between people, their technology and economy, and their natural environments or, in Harris’ terms, between infrastructure and structure. Ecology is the study of interactions and causal links between living entities and their natural and physical environments. Cultural ecology looks at the adaptive processes by which human groups and their culture are affected by adjusting to a given natural environment (Steward 1955). Steward defined the effective environment as the resources that are available in the local environment that could be obtained with the available technology of the human group. The effective environment Archaeological Research Design for the Antelope Valley Study Area 116 07A3822 Task Order 17 consists of the edible foods and places of habitation that are available to humans with a given technology in a given environment. The organization of labor required for resource acquisition (intensity, seasonal and spatial distribution, and work group composition) is based on the combination of effective environment and technology. Social and economic organization and various other elements of culture are shaped by the work process and other interactions between technology and effective environment (Bettinger 2001). Steward (1955) termed the interaction between the effective environment, technology, and socio-economic organization the “culture core.” Cultural ecology provided the analytical framework that became the foundation of modern hunter– gatherer studies (Bettinger 2001; Winterhalder 1984). However, two other variables, population and social relationships, have been found to be important for hunter–gatherer studies. Population and Optimal Foraging Because Steward’s information was based on ethnography, his models did not include change over time, and population was seen as a dependent variable, increasing or decreasing with technological and environmental change. Beginning in the late 1960s population emerged as an important independent variable in hunter–gatherer studies based on environmental changes at the end of the Pleistocene and the beginning of domestication and agriculture in the Old World (Binford 1968; Flannery 1971). The development of optimal foraging theory (OFT) in the 1980s contributed to seeing population as an independent variable. Two models, diet breadth and patch choice, were borrowed from evolutionary ecology and demonstrate the importance of population growth in hunter–gatherer studies (Smith 1983). In both models, energy necessary for food procurement includes energy expended during the time devoted to harvest/hunt the specific food(s) and the energy expended during the time invested in the search for, and travel to, locations where food resources occur. Highranking resources in the diet breadth model are resources that occur in high densities or require low energies to procure. High-ranking patches in the patch choice model are those that provide the greatest amount of energy for the least amount of time invested in obtaining the food (excluding search or travel). According to OFT, the highest ranked resource or patch is always used and preferred. However, if the highest-ranked resource or patch is rare, lower ranked resources or patches may also be used because their greater availability reduces search and travel time (Bettinger 2001). The diet breadth model was used to explain the role of increasing population in changes in subsistence at the end of the Pleistocene and in the beginning of agriculture (Bettinger 2001). Growing populations reduced the abundance of highly ranked large profitable resources, such as big game, and more abundant lower ranked resources, such as seeds and shellfish, were added to the diet. Later, increasing population promoted domestication and agriculture, which required increased handling time and tending (herding of animals or sowing, cultivating, and harvesting). Use of these lower ranked (because of increased handling time), but more abundant resources, in turn sustained Archaeological Research Design for the Antelope Valley Study Area 117 07A3822 Task Order 17 population growth. According to the patch choice model, population growth increased the number of consumers per resource and decreased overall environmental productivity such that travel between widely spaced rich patches would become less profitable than foraging more intensively within fewer patches (Bettinger 2001). Increased sedentism led to higher population densities and decreasing mobility-related infanticide. While the diet breadth and patch choice models were initially used to discuss the beginning of agriculture (Barlow 2006), they have been applied to hunter–gatherer studies where population growth can cause resource stress leading to subsistence change and, potentially, technological and social change (Bird and O’Connell 2006; Lupo 2007; Nettle et al. 2013; Winterhalder and Bettinger 2010). Hunter–gatherer studies have shown that adaptive change results from resource stress resulting from population growth (population-resources imbalances) (Bettinger 2001). This is known as intensification (discussed below). In the modern view of hunter-gather studies, population and environment are in a system of mutual feedback that causes population and resources to oscillate inversely (Belovsky 1988; Winterhalder et al. 1988) so that there is no fixed carrying capacity. Optimal Foraging Models Optimal foraging theory is based on the assumption that individuals make rational decisions when there are limited resources and unlimited needs. That is, among hunter-gatherers, decisions are made to maximize the net rate of energy gain. Such decisions may include decisions about diet choices, foraging location and amount of time spent foraging, foraging group size, and settlement location (Bettinger, Garvey, and Tushingham 2015:92). The most common optimal foraging models used in hunter-gatherer studies are the diet breadth model and the central place model. The diet breadth model looks at choices made with respect to kinds of food or prey and their energetic content. In the diet breadth model, the forager tries to select the combination of food types that maximizes net energy intake per unit of foraging time (the amount of energy captured less the amount of energy expended in order to obtain the food). Variables to be considered in selecting a food include the food type’s abundance, the amount of energy produced by the food, and the amount of time or energy needed to acquire the energy from the food, including energy and time expended searching for the food (Bettinger, Garvey, and Tushingham 2015:92). Central place foraging models add a spatial dimension. Foraging is seen as a round-trip from a given point of departure to the patch where a particular kind of food is available and return. In simplistic terms, foragers will travel farther distances (expend more energy and time) if more energy can be obtained from the food type available there (larger prey or plants with higher caloric yields). Thus, choices about prey or food types are based on the energy content of the prey relative to both travel time and handling (processing) time (Bettinger, Garvey, and Tushingham 2015:105-109). Archaeological Research Design for the Antelope Valley Study Area 118 07A3822 Task Order 17 There are problems with applying optimal foraging models to specific real-world cases. Can the return rates associated with specific foraging activities be determined? For example, what are the search and pursuit times applicable to mammoths (Bettinger, Garvey, and Tushingham 2015:105133)? Social Relations While Steward saw social relationships as responding to material conditions, the current view sees social relationships as actions that are independent of material conditions (Bettinger 2001). Cultural anthropologists assumed that homogeneous individual interests coincided with group interests. Thus, individual hunters would limit their take of deer so that there would be more deer for the group as a whole in the future. It was thought that individuals denied their immediate self-interests, in order to benefit the group as a whole. In cultural anthropology this was termed neofunctionalism. However, those studying hunter-gatherers have found that individuals following their own selfinterest do make decisions that may not benefit the group. Thus, social relationships can affect or direct what groups and individuals do with a particular technology and environment (Bettinger 2001). The concept of adaptive strategy is used in the analysis of the complex relationships between environment, technology, population, and social relationships: Adaptive strategies are unified combinations of settlement, subsistence, organizational, and demographic tactics that optimize one or more goals (e.g., risk reduction, time minimzation, energy maximization) that promote hunter–gatherer success in a wide range of techno-environmental settings (Bettinger 2001:145). Collectors and Foragers Binford (1980) proposed a continuum of hunter–gatherer adaptive strategies, known as the collectorforager model, for coping with unfavorable mixes of population and resources in space (too many people or too few resources at a place) or time (too many people or too few resources in a season). When resources are fairly abundant everywhere, but can become exhausted in any one location, the group moves to a new location where resources are more abundant. Thus, foragers move the local group to the resources (residential mobility). However, if environmental productivity is low and resources are distributed differentially, task groups go out to collect different kinds of resources at greater distances from the base camp and bring them back to the base camp. Thus, collectors move resources to the group. Foragers operate out of a temporary base camp which is frequently moved as resources around the base camp are depleted. The forager strategy is successful only if the necessary resources are always available from each new base camp. If this kind of relatively uniform distribution of resources is not present, a collector strategy may be more efficient. Collectors occupy relatively permanent base Archaeological Research Design for the Antelope Valley Study Area 119 07A3822 Task Order 17 camps which may be moved only a few times a year or not at all. Small specially organized task groups are sent out from the base camp to collect resources. Thus, one task group may go out to collect one resource, such as fruits or berries, located west of the base camp, while another may travel east to hunt deer. The age and sex composition of the two collecting task groups will probably differ. These task groups may stay overnight away from the base camp, establishing field camps, a site type not found among foragers. Collectors also practice food storage while foragers usually do not. Large quantities of a seasonally available and storable resource, such as acorns, can be brought back to the base camp by collectors and stored for later consumption during seasons when fewer resources are available. Storage promotes maintaining the base camp in the same location (greater sedentism) in order to access the stored resources and increases even greater reliance on logistical procurement. The differences between foragers and collectors should be represented as a continuum, not a dichotomy. Many groups practiced elements of both strategies. In many cases, the kind of settlement-subsistence strategy employed by a group varied with the season. When resources were abundant throughout the area, they may have followed a forager strategy, but when resources of different kinds were less abundant and were available only in certain dispersed locations or only in a certain season, they may have pursued a collector strategy. Thomas (1983) has proposed a simple scheme of three settlement strategy models for the Great Basin based on ethnographic examples. The first settlement strategy is characterized by fission, small groups foraging throughout a territory in a seasonal round. This is similar to the forager end of Binford's logistical continuum. A second strategy is characterized by fission-fusion where the group maintains a central base for part of the year and breaks up into smaller mobile groups the rest of the year. This strategy combines collector and forager strategies. The third strategy, fusion, is characterized by a semi-permanent village to which collector parties bring back resources. The fusion model is at the collector end of Binford's continuum. Binford's (1980) causal model for the development of a logistic pattern was based on climate: the colder the effective temperature, the more a group would have to rely on stored foods during the less productive part of the year. However, this model does not account for the presence of many logistically organized societies in the temperate zones of the world. Hayden (1986) contends that logistic strategies are adaptive for procuring r-selected resources. R-selected resources have short reproductive cycles and produce large numbers of offspring, each of which individually is a small food package. Examples are seeds, nuts, fish, birds, and small mammals. This contrasts with kselected resources which have long reproductive cycles and produce few but relatively large offspring which are protected by their parents. Most k-selected resources are large mammals such as elk, bighorn sheep, deer, bear, mountain lion, etc. While r-selected resources are abundant and reliable, they have much higher processing and storage costs. Thus, a logistic settlement system with storage and a semi-sedentary settlement pattern is an adaptation to expending additional energy to harvest large amounts of storable r-selected resources on a reliable basis. Archaeological Research Design for the Antelope Valley Study Area 120 07A3822 Task Order 17 Foragers, on the other hand, are opportunists and generalists who exploit limited, scarce, and unpredictable resources, usually k-selected large mammals in combination with large package plant foods such as tubers and some r-selected resources which do not require a great amount of processing time and which are usually not stored. Travelers and Processors A model for increasing sedentism among hunter-gatherers in the Owens Valley area of eastern California has been proposed by Bettinger and Baumhoff (1982) who suggested that instead of emphasizing settlement and mobility strategies as in the forager-collector continuum, in some cases it may be more useful for archaeologists to investigate subsistence strategies using concepts from optimal foraging theory. Bettinger and Baumhoff (1982:487) have defined a traveler strategy and a processor strategy. The traveler strategy emphasizes resources which provide more calories per package, such as large game. Costs are greater in travel and search time and lower in extraction and processing time. In the traveler strategy, as resources around the base camp grow scarce, the group moves to an area (patch) where the resource being sought is more abundant. The processor strategy includes more resources which provide fewer calories per package and which require greater extraction and processing time. However, travel and search time are greatly reduced. In the processor strategy, procurement is increasingly directed toward low-quality resources with high processing times. Therefore, it is cheaper to reside and consume resources at the locations of procurement (Bettinger 2001). The processor strategy is, in general, a higher cost strategy than the traveler strategy. Although travel time is reduced, extraction and processing time is much higher. Use of higher cost resources only comes about when lower cost resources become scarce relative to the human population. Thus, in situations of human population increase, search time for low cost resources, such as bighorn sheep or deer, increases. As search time increases, people may be willing to spend more time extracting and processing higher-cost resources such as grass seeds, pinyon nuts, and acorns. Bettinger and Baumhoff (1982) suggested that the processor strategy has a competitive advantage over the traveler strategy. If both kinds of groups were in the same area, population would be higher and travel/search time for large game would increase for both groups. However, since the processor group would be competing for the same resources the travelers use, plus exploiting higher cost resources that the travelers don't use, the processors would have a competitive advantage. Thus, ethnic spread of a new processor group in an area can take place by the replacement of low cost strategies with high cost strategies (Bettinger and Baumhoff 1982:488). According to Bettinger and Baumhoff, this accounts for the spread of Numic-speaking people from the southwest Great Basin throughout the rest of the Great Basin within the last 1,000 years. The Numic speakers and the processor strategy probably originated in the Owens Valley of eastern California as a result of population increase within an environmentally circumscribed area (Bettinger and Baumhoff 1982:497). Archaeological Research Design for the Antelope Valley Study Area 121 07A3822 Task Order 17 Storage and Sedentism Hunter-gatherers who store resources live at higher population densities and are more complex socio-politically. Storage is used where there are reasonably abundant and seasonally predictable resources and where in other seasons there are resource shortages. Sedentism and territoriality are favored in environments where resources are abundant and predictable. Population growth is thought to cause sedentism and territoriality which would otherwise not be adopted because they are costly and risky. However, population growth leads to sedentism and territoriality only where the group maximizes energy (Bettinger 2001). Groups that maximize energy production are processors who maximize the amount of energy extracted from low-quality resources with high processing times, such as seeds and nuts. People who instead minimize time are mobile travelers who minimize processing and extraction time by focusing on resources which provide more calories per package, such as large game. The question is, how do time minimizers become energy maximizers? A change in use rights and social relationships is needed for a group to become energy maximizers. Among travelers, all food procured is shared among the group and there is no surplus to store. Among processors, stored or cached food is private property and can be shared with others in the group only after it is removed from the cache. This reduces the amount of food that freeloaders can obtain without having contributed to its extraction and processing. Tolerated theft (sharing) limits forager willingness to invest in small package resources (seeds and nuts). While storage may be a response to growing population pressure, that pressure cannot itself result in storage until the social rules about sharing versus ownership of stored food change. In energy maximizing societies the social relationships and resource use rights favor storage, sedentism, and territoriality. In timeminimizing societies they do not (Bettinger 2001). The question is how a time-minimizing society becomes an energy-maximizing society. Bettinger (2001) has hypothesized that the adoption of the bow and arrow for hunting, a technological change, was the catalyst for change from a time-minimizing society to an energymaximizing society. The bow and arrow allowed a shift from group hunting to individual hunting and made hunting more efficient and productive. Individual hunters could then compete for mates based on their hunting skills. The better hunters could often have more than one wife who could share the labor of plant food processing. Investment in greater labor in plant food processing was in the selfinterest of women who also competed for mates through their efficiency in plant food processing and their desire to reduce their plant food processing labor by sharing the labor with another wife. This could have led to storage of plant foods and changes in the rules about ownership of stored resources. Intensification Intensification has been defined as “the sum of additional material and labor devoted to increasing the yield of currently available resources” (Beaton 1991:951). Intensification entails adding one or more lower-ranked resources to the diet which require additional extraction or processing costs. Archaeological Research Design for the Antelope Valley Study Area 122 07A3822 Task Order 17 New technology or organization of labor may be used to more efficiently exploit a lower-ranked resource. Population and circumscription are seen as driving intensification (Beaton 1991). Subsistence intensification results from altered production requirements arising from populationresource imbalances which, in turn, can be a result of population increase, deterioration of the environment with decreased availability of resources, and a need to meet increased social demands (Basgall 1987). “Subsistence intensification refers to any change in extractive strategies that results in increased levels of production at the expense of greater time energy or material expenditure” (Basgall 1987:42). The reasons intensive acorn use in central California began relatively late in time (indicated by large scale mortar-pestle use after 4,000 to 1,000 BP, depending on the geographic area) include variability in acorn production by oak trees from year to year and the intensive labor required for processing acorns, which includes shelling, grinding, and leaching. Acorn use was a high-cost subsistence orientation that was not used until increased production at the expense of productivity was necessary due to increasing population size and density (Basgall 1987). Macrobotanical studies of charred seeds and nuts from archaeological sites in central California corroborate Basgall’s (1987) study of the timing of acorn use which was based on the appearance of mortars and pestles. The results of the macrobotanical studies show that acorn use began in the Middle Period and continued through the Late Period (Wohlgemuth 1996). Small seed use was found in the Early, Middle, and Late Periods, although small seed use declined during the Middle Period. During the Middle Period it is possible that people decided to fish for salmon during the spring instead of collecting small seeds. Intensification of resource use in California took many forms and was not confined to acorn use. In the Newport Coast area of Orange County, California, intensification included procurement of a greater number of smaller animals with less meat per individual, procurement and transport of resources from greater distances from the residential base, and application of greater labor in managing the environment, as seen in controlled burning or fire management to promote increased seed production. All of these intensification techniques were practiced during the Late Prehistoric Period, but not during the earlier Milling Stone Period. There is also evidence for some of them in the Intermediate Period (intermediate in time between the Milling Stone Period and the Late Prehistoric Period) (Mason 2014). There is also evidence for intensification of hunting (a shift to increasingly smaller vertebrate species) in central California (Broughton 1994), procuring sea mammals in the Chumash area (Raab 1996), and bird procurement in the San Francisco Bay area (Broughton 2001). Evolutionary Archaeology In the 1990s evolutionary archaeology was developed to focus on the explanation of change using the concepts of Darwinian evolution (O’Brien 1996; O’Brien and Lyman 2000). Modern evolutionary archaeology focuses not on the evolution of culture itself, but on the evolution of cultural phenomenon, such as artifact types. Products of technology (artifacts) are active components in the adaptive process. They are active because of their variation. The “variants represent alternative Archaeological Research Design for the Antelope Valley Study Area 123 07A3822 Task Order 17 solutions to adaptive problems and have different reproductive consequences for their makers and users” (O’Brien and Lyman 2000:7). Artifacts, the results of behaviors, are seen as an extension of the human phenotype (the physical appearance or characteristics of an organism as a result of the interaction of its genotype and the environment). With that understanding, the Darwinian concepts of selection and drift can be applied to the variation in the archaeological record. The variation in the archaeological record is expressed in the artifact types constructed by archaeologists to provide information about variation in style or function. “Evolutionary archaeology is about constructing lineages [sequences of change over time] that can be explained in terms of Darwinian theory” (O’Brien and Lyman 2000:13). It is thought that “individuals producing and using artifacts that better adapt them to their environment will live longer and produce more offspring, ensuring the persistence of the artifacts that made that possible” (Bettinger, Garvey, and Tushingham 2015:190). Evolutionary archaeology is based on selection by individuals acting on variation in artifact types. The only real-world example of the application of evolutionary archaeology has been to explain the sequence of change from Clovis points to Dalton points (O’Brien and Lyman 2000:345-375). Human Behavioral Ecology Human behavioral ecology pertains to the “study of evolution and adaptive design in an ecological context” (Winterhalder and Smith 1992:3) and more particularly to the evolution of human behaviors. While evolutionary archaeology emphasizes the evolution of artifact types, Human behavioral ecology emphasizes the evolution of behavior. Specific behaviors should affect the genetic fitness of individuals and when those individuals reproduce, the behaviors are passed on. If behavioral variability … results in differential genetic fitness and if such behaviors … are transferable from one individual to another, then this transfer necessarily carries with it the implication of genetic fitness” (Bettinger, Garvey, and Tushingham 2015:194). Human behavioral ecology has had to deal with the problem of altruistic individuals who sacrifices self-interest to further the interests (genetic fitness) of other individuals in the group. Altruistic behavior would seem to contradict the Darwinian concept of survival of the fittest where each individual competes with others on the basis of self-interest. This problem led to the consideration of the overall fitness of a group which may contain smaller or larger proportions of altruistic individuals. Thus, human behavioral ecology takes into account the costs and benefits of cooperation and sharing to individuals within a group. Group benefits may be at odds with individual interests. The tension between group and individual interests may account for the cycles of fissioning and fusing that characterizes the sociopolitical organization of many huntergatherer groups (Bettinger, Garvey, and Tushingham 2015:202). Optimal foraging theory is a part of human behavioral ecology in the sense that an optimal forager who, based on objective rationality, makes choices about the combination of food types that maximizes net energy intake will be more genetically fit. The question is whether foraging efficiency based on objective rationality is the most important determinant of genetic fitness. Others have argued that cultural preferences are also important (Bettinger, Garvey, and Tushingham 2015:203). Archaeological Research Design for the Antelope Valley Study Area 124 07A3822 Task Order 17 These cultural preferences develop as a result of subjective rationality (rather than objective rationality) and are learned through cultural transmission processes, as discussed in the next section. An example is hunters who kill more deer in order to “show off” by sharing meat with a wider group than just his immediate family. The hunter is more interested in acquiring prestige rather than energy and engages in “costly signaling” in order to attract a mate (Bettinger, Garvey, and Tushingham 2015:222). Thus, the hunter’s goal is not foraging efficiency, but passing on his genetic information. Cultural Transmission While neo-Darwinian evolutionary archaeology used a process similar to genetic transmission (transfer of information from parents to children to form a vertical lineage), more recent neoDarwinian evolutionary theory uses the concept of cultural transmission through learning. Cultural transmission can impart information both vertically (from parents) and horizontally (from teachers or peers) through guided variation and content-biased transmission. Guided variation refers to individual invention and learning while content-biased transmission is the ability to evaluate alternative cultural behaviors rationally (Bettinger, Garvey, and Tushingham 2015:243). Learning does not require behavior variability, but through experimentation and errors, produces new behaviors (behavior variation). Content-biased transmission starts with a range of behavioral variants but works to eliminate variation (behaviors that are less productive are not selected). Because natural selection has presumably shaped learning and the development of content biases, both lead “in the long run to behaviors that result in genetic fitness in accord with Darwinian theory, even though genes are not involved” (Bettinger, Garvey, and Tushingham 2015:248-249). Neo-Darwinian cultural transmission has been used to provide a preliminary explanation for the Upper Paleolithic transition (changes in stone tools, evidence of long distance trade, and organized hunting of migrating herd animals circa 50,000 years ago) and the transition from atlatl to bow and arrow technology in the Great Basin (Bettinger, Garvey, and Tushingham 2015:265-271). Landscape Archaeology Landscape Archeology is the analysis, through material culture, of the spatial dimension of human activity; in other words, exploring how human communities have related to a geographic space through time in terms of how they appropriated this space and/or transformed its appearance through work and its significance through cultural practices (Parcero-Oubiña, Criado-Boado, and Barreiro 2014). Landscape archaeology is the study of ways past peoples shaped their landscapes through cultural and social practices, and how people were influenced, motivated, or constrained by their natural surroundings. The land may be perceived and shaped based on symbolic processes including sense of place, memory, history, and legends. Archaeological Research Design for the Antelope Valley Study Area 125 07A3822 Task Order 17 Landscape archaeology integrates philosophical approaches to landscape perception with anthropological studies of the significance of the landscape in small-scale societies. It includes examination of the relationship between prehistoric sites and their topographic settings. Neolithic stone tombs in Europe have been described as a means to focus attention on nearby landscape features such as rock outcrops, river valleys, and mountain spurs. The Neolithic monuments played an active role in socializing the landscape and creating meaning in it (Tilley 1997). Critics have questioned how observations of a contemporary landscape can be used to understand the perception and meaning assigned to a landscape by prehistoric people. In response to this problem, landscape archaeology in the United States has focused on historic period landscapes where historical sources can be used for interpretation (Yamin and Metheney 1996) and on Native American cultural landscapes where oral history can be used to provide meaning and context. Areas traditionally occupied by Native American tribal groups are recognized today as containing both traditional cultural properties and cultural landscapes. Individual places that were and are of cultural significance to Native American communities are often referred to under federal historic preservation guidelines as “traditional cultural properties”, which may be found eligible for listing in the National Register of Historic Places (Parker and King 1998). Within the definition of native places are included both localities that were of traditional religious significance to Native Americans and what are called “traditional use areas”. The latter term is applied to areas where native people carried out important traditional gathering or procurement activities, and where the locations of these activities were recalled in native oral history. Where a number of native places and areas are documented for a particular region, these places are referred to as part of a cultural landscape. As defined by the Advisory Council on Historic Preservation (2011, 2016) and the National Park Service (Page 2009), Native American cultural landscapes consist of both physical manifestations of the native use of their local habitat (the remains of habitation sites, trails, quarries, rock art sites, or hunting camps, for example) and of places and areas that were and are culturally and/or religiously significant to these native inhabitants and their descendants. Such places of cultural and religious significance were often named. Individual places and areas of cultural significance fit in to a wider “landscape” or spatialgeographical panorama that had distinctive cultural meaning for native people. This meaning was, and remains, in part religious and supernatural. These places or constellations of places may encompass extensive geographical areas, like sacred mountains. Sacred places and sacred cultural landscapes may contain physical characteristics or attributes "on the ground" that connect them with Native American groups and their traditional beliefs. However, a natural landscape feature with supernatural associations as a sacred place, like a sacred mountain, need not contain within it any tangible imprint of human occupation, activity, use, or cultural/religious significance in order for it to be considered a sacred place or part of a sacred cultural landscape. Native beliefs, past and/or present, about the significance and sacred attributes of Archaeological Research Design for the Antelope Valley Study Area 126 07A3822 Task Order 17 the place are what define its sacred character. Other native places of non-sacred cultural significance may similarly lack such visible "footprints” of native use or association "on the ground". Thus, indigenous cultural landscapes also frequently constitute sacred cultural landscapes, based on religious beliefs about such constellations of sacred places held by Native Americans. These may have been recorded by ethnographers, be preserved in native oral literature, and may form part of contemporary Native American cultural heritage and religious belief. Both individual sacred places and sacred cultural landscapes may be eligible for nomination to the NRHP as Traditional Cultural Properties, also known as Traditional Cultural Places, as defined and discussed in National Register Bulletin 38 (Parker and King 1998). Sacred places may also separately be eligible for federal protection when located on federal lands under Executive Order 13007: Indian Sacred Sites (Advisory Council on Historic Preservation 2002, 2013). In that case, different criteria for eligibility apply than in the case of Traditional Cultural Properties, along with a greater level of site protection. Indigenous Archaeology Indigenous archaeology has developed in parallel with the participation by indigenous communities in the United States and elsewhere in the preservation and management of their cultural heritage. It is also linked to indigenous maintenance or recuperation of cultural identity and political sovereignty, as well as the implementation of repatriation. This management of cultural heritage includes work with and evaluation of prior ethnographic research (Warren and Barnes 2018). It is an archaeological perspective or approach that has developed in response to critiques by indigenous communities of traditional archaeological attitudes and practices (Colwell-Chanthaphonh et al. 2010, Ferguson 1996, Nicholas 2008, Smith and Wobst 2004, Watkins 2005). It has become important over the last thirty years, especially in regions of the world where cultural resource management archaeology has been supported by laws mandating the protection of archaeological resources and where laws exist recognizing the rights of indigenous peoples. It has emerged in the context of the post-modernist critique of the Western cultural view of science as the exclusive vehicle for understanding the world. It has also developed in the context of the assertion by indigenous communities of the importance of their right to control disposition of human remains, as well as of artifacts of special cultural significance and other archaeologically-recovered materials. Indigenous Archaeology and Processes of Collaboration This literature treats a number of different aspects of indigenous archaeology. This includes the integral involvement of native people and communities in the successful undertaking of archaeological projects and in the development of archaeological knowledge that serves the needs of native communities. Central to this effort is the crafting of research objectives that reflect native perspectives and concerns regarding what is important about the native past, and that reflect native understandings about how that past unfolded and why it is significant to native communities today. This effort is part of a wider undertaking to broaden the viewpoints of scholarly enterprises in history, anthropology, and other social sciences that deal with the history and culture of indigenous peoples Archaeological Research Design for the Antelope Valley Study Area 127 07A3822 Task Order 17 around the world- sometimes referred to as scholarly 'decolonization'. This theme is discussed by Smith and Wobst (2005). Community-Oriented Archaeology Atalay (2012) provides a guide to carrying out archaeological projects through collaboration with local indigenous or other communities from project inception. An important point she makes is that indigenous or other community involvement is important for 'sustainable' archaeology, projects and research programs that receive institutional and public support because they meet community needs. 'Sustainable' archaeology also means that archaeological resources can be better protected where local communities have been involved in their study through community archaeology and also involved in interpreting their importance within the context of local culture and history (Atalay 2012:1-22). In many areas of the world, it is now common for archaeological projects to establish partnerships with local communities, as with indigenous and other local communities in Latin America. Atalay (2014) also discusses the issues of maintaining objectivity and methodological rigor in carrying out community collaboration-based archaeology. Colwell-Chanthapohn and Ferguson (2008) discuss the dynamics of community collaboration in working with native communities, moving along a continuum from 'communities of resistance' to 'communities of collaboration', while recognizing the practical challenge that this collaborative ideal may raise. Atalay, Clauss, McGuire, and Welch (2014) have provided a comprehensive statement on how archaeology can be retooled as an interpreter of human heritage to serve local communities and wider non-privileged constituencies. Clauss (2014) discusses archaeological activism and the challenges and neccessary considerations involved in advocating for native communities as an activist archaeologist involved in indigenous community-based archaeology. Archaeological Investigation and Native Interpretation of Cultural Landscapes Native interpretations of the nature and significance of cultural landscapes studied through archaeological research are a key element of collaboration in the mode of indigenous archaeology. Ferguson and Colwell-Chanthaphonh (2006) discuss the example of the San Pedro Valley in Arizona, significant as a homeland to the Tohono O'odham, Western Apache, Hopi, and Zuñi. There an ethnohistorical project in support of archaeological work was conducted in collaboration with tribal research teams and on the basis of tribal review. The project provides a model for multi-tribal collaboration based on native groups sharing in the direction of the research process. A native collaborative project in a different environmental setting is described in Ball et al. (2017). Northwest U.S. native nations- the Makah Tribe, the Confederated Tribes of Grand Ronde Community of Oregon, and the Yurok Tribe- with the Bureau of Ocean Energy Management, National Oceanic and Atmospheric Administration, in documenting and protecting coastal and marine tribal cultural landscapes. The national and international context of collaborative efforts at documentation and protection of Traditional Cultural Places and Tribal Cultural Landscapes is also discussed in this document. Archaeological Research Design for the Antelope Valley Study Area 128 07A3822 Task Order 17 The Archaeology of the Colonial Encounter Native American archaeologists in California have turned to the examination of the colonial encounter between Spanish colonial institutions and native communities. Schneider and Panich (2014) provide a discussion of research on native agency and the rethinking of the colonial encounter in the Spanish mission system in California and elsewhere. Schneider, a Native American scholar, has researched the archaeological context of the colonial encounter in the San Francisco Bay region, in the vicinity of the ancestral territory of his community (Schneider 2010). Schneider's research has focused on the reconceptualization of the processes of native interaction with and resistance to the Franciscan mission system and other elements of the Spanish colonial regime. The Schneider and Panich volume reflects archaeological research interest in native resistance in the form of mission revolts and native flight to regions of refuge (Bernard, Robinson, and Sturt (2014). Indigenous Archaeology and Community Access to Archaeological Knowledge Indigenous archaeology is also linked to a dual tradition within anthropology as a discipline. Anthropology has traditionally pursued empiricist scientific research objectives focusing on comparison of human biological and cultural characteristics, while at the same time, in a critique of colonialist ethnocentric assumptions, describing and demonstrating and, in effect, legitimizing human cultural diversity and indigenous knowledge and cultural practices. Kroeber pointed out that anthropology is both a science and a humanity- these two different goals of anthropology is what he was referring to. Indigenous archaeology attempts to bring together these two traditions of empirical scientific research and the valuing of indigenous knowledge and culture. Anthropology has been described as a handmaiden of colonialism, but it has also provided both the data and theory to discredit it. Several particular points of emphasis for indigenous archaeology include the participation of indigenous communities in archaeological practice, as archaeologists, as archaeological monitors, as reviewers of project reports, and as consultants in the interpretation of archaeological sites, features, and artifacts. Indigenous archaeology advocates for indigenous communities having not only participation in the archaeological process but also a voice in what the product will be as well. Indigenous archaeology undertakes to shift the archaeological narrative from a focus on material culture analysis and "cultural materialism" (and even a focus on supposedly universally-valid behaviorist models) to one more user-friendly for indigenous people, where the unique religious and cultural traditions and values of native cultures are more fully taken into account. Indigenous archaeology emphasizes that indigenous archaeological sites and artifacts should not simply represent raw material for the assembling of abstract theories about human behavior and cultural development. They are an important and tangible part of the history and heritage of specific living communities. Indigenous archaeology values oral historical traditions, community ethnographic knowledge, and indigenous interpretations of local history, culture, religion, and the origins of things. Indigenous archaeology also recognizes that, just as the development of archaeology in the Western world reflected a European cultural agenda, archaeology at the service of indigenous communities Archaeological Research Design for the Antelope Valley Study Area 129 07A3822 Task Order 17 can respond to the questions and concerns that these communities themselves have about their past and their cultural heritage. Summary Archaeologists carrying out research in the Antelope Valley generally espouse the major goal of cultural reconstruction of settlement and subsistence systems through the use of optimal foraging theory, the collector-forager continuum, traveler-processor strategies, and investigations of storage and intensification. This focus is understandable given the paucity of information from archaeological investionations of prehistoric lifeways in the region. As more is understood through continued studies in the Antelope Valley, theoretical frameworks for explanation of cultural adaptations/change, including evolutionary archaeology, human behavioral ecology, and cultural transmission, should be applied when these theories and models can be better articulated with archaeological data. Most of the current examples that use these approaches are based on ethnographic or modern case studies. Importantly, the empirical and materialist approaches should be supplemented by concepts such as those from landscape archaeology and indigenous archaeology that will allow researchers to move beyond cultural reconstructions from a single perspective to more diverse perspectives. Cultural landscapes can be given meaning and context by using Native American oral history. Indigenous archaeology focuses on the cultural traditions and values of native cultures and takes into account indigenous interpretations of local history, culture, and religion. Archaeological Research Design for the Antelope Valley Study Area 130 07A3822 Task Order 17 Archaeological Property Types Archaeological property types or site types for the prehistoric period in the Antelope Valley were defined in the Overview of Prehistoric Cultural Resources for Edwards Air Force Base (Earle et al. 1997), and is a very useful starting point for understanding site types in the region. However, as more investigations are carried out in the Antelope Valley, revisions to this list of site types and what archaeological remains/features may represent must be considered/undertaken. Specifically, researchers should be mindful that the list of site types presented below, along with definitions and attributes, are in some ways subjective and require continuous refinement. The number of sites of each type that occur on Edwards Air Force Base have been quantied. As of 1997 there were 465 lithic scatters and flaking stations, comprising 42% of the sites on Base, and there were 416 temporary camps, comprising 38% of the sites on Base. Other site types present, but not as common, include hearth and roasting features (9%) milling stations (5%), lithic quarry sites (1%), rock shelters (less than 1%), residential bases or villages (less than 1%), cremations (less than 1%), rock alignments (less than 1%), pictographs (less than 1%), faunal bone scatters (less than 1%, and isolated finds (less than 1%). Villages have “extensive and deep middens, considerable material culture, exotic materials, cemeteries, and architecture, and are thought to represent more or less permanent occupation locales” (Sutton 2016:269). All the major classes of cultural material are present including flaked stone tools, ground stone tools, debitage, fire-affected rock, hearth and other features that may indicate houses, and subsistence waste. Non-local artifacts can include trade items such as large quantities of shell beads. Rock art may be present. Residential Bases are intensively occupied habitation sites (Earle et al. 1997). These complex sites are characterized by extensive scatters and quantities of cultural material, midden, fireaffected rock, flaked stone tools, lithic debitage, burned bone, milling tools, hearths, rock rings, and sometimes house structures. Temporary Camps were occupied by a small number of people for a short period of time (Earle et al. 1997). They are smaller and less complex archaeologically than residential bases, but more complex than lithic scatters. They are characterized by flaked stone tools, lithic debitage, fire-affected rocks (indicating overnight stays), and may have features such as hearths, but they seldom exhibit midden. Definitions of the other site types (with slight resivions) are as defined by Earle et al. (1997:81-92) for use in archaeological investigations at Edwards AFB: Archaeological Research Design for the Antelope Valley Study Area 131 07A3822 Task Order 17 Utilized Rock Shelters are cultural sites located in rock shelters, caves, or rock overhangs. They are further subdivided by type of use. Occupation rock shelters are rock shelters, caves, or rock overhangs that were occupied temporarily or seasonally. Their cultural deposits are similar to those of base camps, villages, or temporary camps. Transient rock shelters are rock shelters or overhangs used as temporary camps. Cultural remains are minimal, not-more than an isolated tool, a few flakes, or some fire-affected rock. Storage rock shelters are small rock shelters or overhangs containing cultural remains indicative or storage activities such as tool or food caches. Milling Stations are sites where food processing with groundstone tools was the primary activity. Associated artifacts may include manos, metates, mortars, or pestles. A few flaked stone tools or fire-affected rocks may be present, but milling activities must be dominant. This category is further subdivided into bedrock milling slicks, bedrock mortars, and milling stations. Milling stations are isolated portable metates or mortars associated with fewer than 10 other items. If the milling station is associated with more than 10 other items, it is categorized a temporary camp. Lithic Scatters are sites composed entirely of flaked stone tools and debitage with no other class of cultural materials and no evidence of occupation. Lithic scatters are further subdivided by size and density of cultural materials. Large, dense lithic scatters are over 50 square meters in size and have more than 30 items for every 10 square meters. Large, light lithic scatters are over 50 square meters in size but have less than 30 items for every 10 square meters. Small, dense lithic scatters are less than 50 square meters in size but have more than 30 items for every 10 square meters. Small, light lithic scatters are less than 50 square meters in size and have less than 30 items for every 10 square meters. Flaking Stations consist of one or more cores surrounded by related flakes and possibly hammer stones. These sites are usually 1 or 2 meters in diameter, but they may be larger if there are a cluster of flaking stations less than 50 meters apart and more than 100 meters from another site, in which case the flaking stations may be recorded as a single site. If a flaking station is associated with other cultural materials, it is assigned another site type. Quarry or Lithic Sources are places where naturally occurring lithic material has been utilized to make flaked stone tools. The quarry or source may be a primary source such as a bedrock outcrop or a secondary source such cobbles in a drainage that have washed down from a bedrock outcrop. Quarries or lithic sources are characterized by flakes, cores, occasional hammer stones, preforms, rejected stones, and flaking stations. This category has three subtypes: exploited bedrock (in situ) Archaeological Research Design for the Antelope Valley Study Area 132 07A3822 Task Order 17 lithic sources, exploited float lithic source, and sources with no evidence of exploitation. Ceramic Scatters consist of scatters of ceramic sherds or broken ceramic vessels with relatively few, if any, other artifacts or features present. Small concentration of sherds may represent pot drops. Cemeteries are concentrations of Native American human interments (inhumations and/or cremations). Cemeteries usually occur near habitation sites. Cremations are burial features consisting of charred human bone fragments with or without associated funerary items. They may be found in small cavities in rock outcrops, in dunes, in utilized rock shelters or caves, cemeteries, or in base camp or village sites. Intaglios are large animal, human, or geometric figures produced on the desert floor by scraping away the desert pavement. Miscellaneous Rock Alignments arid Features are constructed of cobbles and boulders and include simple lines or walls, isolated rock rings, and complex abstract or geometric designs. Petroglyphs are pecked or incised pictures on boulders, rock outcrops, or rock shelter walls. Pictographs are paintings on the walls of sheltered caves, boulders, or rock outcrops. Trails are faint linear impressions or clearings in desert pavement or slight shelves along hillsides or canyon slopes that mark prehistoric travel routes. Roasting Pits or Hearths are sites consisting of fire-affected rock features with few or no other cultural remains. If the site has more than 10 items in addition to fireaffected rock, another category should be used. This site type has two subtypes: single features and multiple features. Prehistoric Cairns are piles of cobbles or boulders that sometimes mark trails, shrines, or burials. They may occur singly or in dusters. There are two subtypes of cairns: single features and multiple features. Non-Human Bone Scatters are clusters of non-human bone. Sites are only assigned to this category when there are no artifacts or features associated with the bone scatter. Archaeological Research Design for the Antelope Valley Study Area 133 07A3822 Task Order 17 RESEARCH THEMES, QUESTIONS, AND DATA NEEDS Archaeological Research Design for the Antelope Valley Study Area 134 07A3822 Task Order 17 Theme: Paleoenvironmental Reconstruction This chapter provides an overview of the Late Pleistocene and Holocene paleoenvironment for the Mojave Desert and the Antelope Valley. This overview is based on a combination of paleoclimate models, geological studies, paleovegetation studies, and archaeological studies. Unfortunately, few studies have been specifically undertaken for the Antelope Valley. The few studies that have focused on the Antelope Valley tend to be focused on Edwards Air Force Base (AFB) in the eastern portion of the Valley with little research conducted on the central and western portions of the Valley. Therefore, the reconstructions completed for the larger Mojave Desert and Great Basin regions are used in this review and when present specific Antelope Valley data is incorporated. The Antelope Valley had a wetter, cooler environment than today at the end of the Pleistocene, but during the Middle Holocene the climate was hotter, more arid than today. More specifically, six major climatic periods have been identified from the end of the Pleistocene through the present. The Late Pleistocene in the Mojave Desert was marked by a period of a pluvial lake stands and low-elevation woodland covering the valley areas. The shift to a hotter, drier climate was accompanied by desiccation of the pluvial lakebeds and an upward shift of woodland environments from the valleys to the foothills and mountains, along with the establishment of desert scrub in the valley areas. These changes are discussed in greater detail in the sections below. Paleoenvironment of the Mojave Desert Proxy vegetation records such as those of pollen, microfossils, pack rat middens, and tree rings; radiocarbon dating of shell and other organic material in drill cores from ancient lake sediments; geomorphology; and modern distributions of plant species have been used to provide insight and an understanding of what appears to have been a complex and variable climate since the Late Pleistocene. Most scholars agree that regional differences and climatic conditions during the last 8,000 years of prehistory (the Middle and Late Holocene) have been variable and witnessed oscillations in temperature and precipitation (Earle et al. 1997; Minnich 2007). Since the Last Glacial Maximum (LGM), circa 21,000-18,000 years ago, researchers have posited at least six major worldwide climatic episodes, each of which manifested itself in the Mojave Desert and likely had a significant effect on its environment. The vegetation of the Mojave Desert has changed dramatically since the Wisconsin Glacial Episode (maximum about 18,000 years ago) in response to changes in the environment (fluctuations between wet and dry periods, and temperature variation). Scholars have reconstructed vegetation changes using plant remains from pack rat midden contexts (Rhode 2001; Spaulding 1990; Spaulding et al. 1994; Thompson and Mead 1982; Wigand and Rhode 2002). For example, using pack rat midden Archaeological Research Design for the Antelope Valley Study Area 135 07A3822 Task Order 17 data from the Silurian Valley and the Granite Mountains northeast of the Antelope Valley Study Area, Koehler and Anderson (1998) provided a nearly 8,800-year reconstruction of vegetation history for the central Mojave Desert which can also be applied to the Study Area. Last Glacial Maximum, circa 21,000-18,000 BP The Last Glacial Maximum (LGM) has been characterized by a mean temperature approximately 7 degrees centigrade cooler than it is now, with continental ice sheets covering much of western North America. Sea level along the Pacific Coast was about 120 meters lower than today, with a coastline 30- to 40-kilometers farther west. Inland in the Mojave Desert, the cooler temperatures and greater precipitation of this period resulted in extensive alpine glaciers in the Sierra Nevada and increased snowfall in the Tehachapi, San Gabriel, and San Bernardino Mountain ranges bordering the valley floor (now part of the Mojave Desert). Snow and ice melt, as well as rain runoff, from these mountains flowed to the valley floor along numerous drainages, including the Mojave and Owens Rivers, and filled valley basins with deep perennial lakes, some of which covered hundreds of square kilometers (Enzel et al. 1992, 2003; Orme and Yuretich 2004; West et al. 2007). Coniferous trees, primarily pinyon pine and juniper woodland, covered large expanses of the valley floor (Jones and Klar 2007; Sutton et al. 2007; West et al. 2007). Pleistocene/Holocene Transition, circa 18,000-10,000 years BP, and Younger Dryas, circa 12,90011,400 years BP After the LGM, research indicates that the climate gradually began to warm, sea level began to rise, and glaciers in the Sierra Nevada slowly began to melt. However, oscillations between cooler stadial and warmer interstadial climates appear to have marked an 8,000-year period between the end of the LGM and the end of the Pleistocene around 10,000 years BP. The most severe of the cooler stadial periods may have been the Younger Dryas (ca. 12,900-11,400 years BP), which brought a return to near-glacial conditions for more than a millennium during the Pleistocene/Holocene Transition. During the Late Pleistocene and Pleistocene-Holocene transition, between 18,000 and 12,000 years ago, woodlands were found at lower elevations compared to modern distribution and covered much of the Mojave Desert. Only the lowest elevations, in Death Valley, were too low to contain woodlands (Minnich 2007). During this time, the Mojave Desert appears to have had Utah juniper woodland thriving below 1,000 meters above mean sea level (AMSL) (Spaulding et al. 1994). McCarten and Van Devender (1988) analyzed pack rat midden plant remains from Scodie Mountains in Kern County (north of Antelope Valley) which revealed that vegetation during this period was dominated by Pinus monophylla (pinyon), Juniperus californica (California juniper), and Ceanothus greggii (desert ceanothus). For the central Mojave Desert valley floor, Koehler et al. (2005) analyzed 47 pack rat midden samples and concluded that prior to ca. 11,500 BP the valley floor vegetation included Pinus monophylla (pinyon), Juniperus osteosperma (Utah juniper), Purshia mexicana (bitterbush), Cercocarpus ledifolius (mountain mahogany), and Prunus fasciculata (desert almond) woodland above 1,000 meters. This Pinyon–Juniper woodland was widespread in the southern and central Archaeological Research Design for the Antelope Valley Study Area 136 07A3822 Task Order 17 Mojave Desert. Juniper woodland graded into juniper and pinyon woodland (1,000-1,800 meters AMSL), which in turn graded into subalpine woodland of limber pine and bristlecone pine at the highest of elevations (Spaulding 1990; Wigand and Rhode 2002). As the climate emerged from the Younger Dryas, it continued a warming trend during the early Holocene, and it is likely that coniferous woodland in the Mojave Desert gradually retreated to higher (cooler and wetter) elevations in the surrounding mountains, giving way to xeric desert vegetation, and some of the large pluvial lakes began to shrink or dry up (Jones and Klar 2007; West et al. 2007). Vegetation changed during the Late Pleistocene-Early Holocene transition, after 12,000 years ago, when the conifer woodland was replaced by desert scrub at lower elevations (Koehler and Anderson 1998; West et al. 2007). By about 8,300 years ago, juniper disappeared from the lower slopes of hills and mountains in the Mojave Desert. Koehler et al. (2005) argue that the northward migration of desert thermophiles began in the southernmost Mojave Desert by the end of the Wisconsin Glaciation as the temperature increased and precipitation decreased. In response to the changes in paleoclimate, the pinyon and juniper moved upslope several thousand feet (Thompson and Mead 1982; Van Devender and Spaulding 1979). During this transition, the composition of the desert scrub vegetation shifted from relatively cooler species, such as Artemisia tridentata (sagebrush), Ericameria nauseosa (rabbitbrush), and Atriplex confertifolia (shadescale); to arid species, such as Ephedra viridis (Mormon tea), Gutierrezia californica (matchweed), Lycium californicum (desert thorn), cacti, and Yucca brevifolia (Joshua tree); to very arid species (such Ambrosia dumosa [white bur-sage], Larrea tridentata (creosote bush), and other desert thermophiles (Spaulding 1990). Holocene Maximum, circa 8000-4000 years BP By around 8000 years BP, higher temperatures and a reduction in rainfall resulted in a hotter and drier period known as the Holocene Maximum (also known as the Altithermal and Mid-Holocene Optimum), which may have continued for about 4,000 years. Unlike the Younger Dryas cooling period, which came and went relatively abruptly, the Holocene Maximum is seen as a more gradual continuation of the post-Pleistocene warming trend that slowly reached a high point, then just as gradually ameliorated (Jones and Klar 2007). Studies of the Great Basin and Mojave Desert are suggestive of great changes in the physical environment of this time for these regions. Most of the pluvial lakes had dried completely, although evidence exists for shallow lake stands during this arid period at Thompson, Owens, and Silurian Lakes (Bacon et al. 2006; Jones and Klar 2007; Orme 2008; Orme and Yuretich 2004; Sutton et al. 2007; West et al. 2007). The decreased precipitation during the Holocene Maximum further resulted in the reduction of the Pinyon-juniper woodlands on the Mojave Desert valley floors. Any remaining coniferous woodland in the Mojave Desert was replaced entirely by desert scrub during this period. In the northern part of the desert where there was more moisture, this retreat upslope was less pronounced. According to Lanner (1983), after 8,000 years ago, the woodlands completely disappeared from the valley floors, and drought tolerant plants (from the south) took over the desert. There were micro-regional Archaeological Research Design for the Antelope Valley Study Area 137 07A3822 Task Order 17 variations to these patterns; for example, Juniperus woodland was lost in the Granite Mountains in the eastern Mojave Desert between ca. 9000 and 7900 years BP (Koehler et al. 2005), however it persisted in the Lucerne Valley (in western Mojave Desert) until after circa 7800 years BP. During the Middle Holocene, the vegetation changed to include Larrea tridentata (creosote bush) starting around 6,910 years ago in the Silurian Valley, 5,960 years ago in Granite Mountains, and by 5,960 years ago in the Nelson Basin (all northeast of Antelope Valley). By 6,800 years ago, Ambrosia spp. (bur-sage) was present on the desert floor. Creosote bush was established by 4760 BP, and it appears that although it arrived early in the Silurian Valley, it took several thousand years to dominate the central Mojave Desert (Koehler et al. 2005). Atriplex confertifolia (shadescale) appeared at the end of the Middle Holocene in the Granite Mountains. West el al. (2007:32) state that by 5,000 years ago, the primary characteristics of the Mojave Desert vegetation as observed today were established, with modern associations developing over the next several thousand years. However, Koehler and Anderson (1998:283) suggest that the “modern composition of dominant vegetation was completed about 4500 B.P.” First Neoglacial (Neopluvial), circa 4000-2000 BP A milder climatic episode began around 4000 BP, bringing the Holocene Maximum to an end. The First Neoglacial, or Neopluvial episode was marked by cooler temperatures, slightly increased rainfall, the proliferation of more mesophylic desert plant species, and the return of shallow lake stands at some of the playas that had been desiccated for most of the past four millennia, including Rosamond, Owens, Searles, Lucerne, Silver, Soda, and Ivanpah Lakes (Bacon et al. 2006; Enzel et al. 1992, 2003; Jones and Klar 2007; Orme 2008; Orme and Yuretich 2004; Robinson et al. 1999; West et al. 2007). Medieval Climatic Anomaly (MCA) circa 1300-700 BP Relatively stable and benign climatic conditions in the Mojave Desert were interrupted when warm, dry conditions began to return around 1300 BP. There is little evidence of perennial lake stands existing in this period, and frequent, severe droughts are thought to have occurred. This climatic episode, known as the Medieval Climatic Anomaly (MCA) (also known as the Medieval Warm Period, the Little Climatic Optimum and the Little Altithermal), may have been more severe and abrupt in its onset than the earlier Holocene Maximum (Moratto 1984; Sutton et al. 2007). Overall, there is little data on how vegetation responded to climatic changes during the MCA. Basgall (2008) reports that paleoenvironmental studies do not suggest any significant vegetation changes in response to the droughts and wet periods of the MCA. Koehler and Anderson’s (1995) studies of rat pack middens did not note any notable shifts in distribution or composition of vegetation communities during the MCA. Little Ice Age (LIA), ca. 600-150 BP As the climate emerged from the MCA, it returned to cooler, wetter conditions and signalled the Archaeological Research Design for the Antelope Valley Study Area 138 07A3822 Task Order 17 beginning of the most recent significant climatic episode, known as the Little Ice Age (LIA) or Second Neoglacial. Globally, this period was characterized by sudden decadal climate fluctuations, generally cold temperatures, advancing continental sheet ice in the extreme northern latitudes, increased rainfall, and expansion of alpine glaciers (Sutton et al. 2007; West et al. 2007). In the Mojave Desert, the LIA was accompanied by a return of cooler conditions that allowed some desert plant communities, including juniper woodland, to increase their range to somewhat lower elevations. There were also periodic shallow lake stands at many of the desert playas (Budinger and Spinney 2004; Moratto 1984; Sutton et al. 2007). Today, the lowlands of the Mojave Desert and Western Mojave Desert are characterized by saltbush/creosote vegetation with mixed desert scrub defining the intermediate elevation slopes (Spaulding et al. 1994). Sheep grazing in the Western Mojave Desert during the last 100 years has had a measurable effect on the vegetation and soils (Web and Stielstra 1979). Notable reduction in above-ground biomass under creosote bushes was observed where heavy grazing has occurred. In addition, there was considerable decrease in inter-shrub densities due to sheep trampling. The Effect of Variations in Aridity on West-East Movement of Plant Communities in the Mojave Desert An important characteristic of the floral composition of the floor of the Antelope Valley in modern times is the variation in plant communities, particularly on an east-west axis, on account of variations in rainfall. This variation in rainfall is reflected in the east to west transition from creosote and shadscale scrub communities grading into Joshua tree woodland, and then into extensive areas of Joshua tree – juniper woodland on the western floor of the valley. This vegetation community grades into juniper woodland, contacting oak woodland in the foothills at the west end of the valley. This pattern in the distribution of vegetation communities has important implications for Holocene paleovegetation distributions in the Antelope Valley. A reconstruction of longer-term variations in rainfall at Edwards AFB indicated that between circa 7700 BP and 1000 BP, average annual precipitation would have oscillated between approximately 185 mm [7.28 in.] and 145 mm [5.7 in] (Earle et al. 1997:31). These longer-term variations in average annual rainfall could be seen as possibly involving a displacement or movement of vegetation communities on the floor of the Antelope Valley some kilometers to the westward or eastward in response to long-term trends of more mesic or xeric conditions, rather than creating region-wide floristic “turnover”. At the west end of the Antelope Valley there may have been plant communities that produced useful food resources for human populations, even during the most arid periods of the Holocene Maximum. Reconstruction of Paleoenvironment of the Antelope Valley Few Antelope Valley-specific paleoenvironmental studies are available in the present literature. The majority of these Antelope Valley studies have been prepared for Edwards AFB in the eastern portion Archaeological Research Design for the Antelope Valley Study Area 139 07A3822 Task Order 17 of the valley. For other portions of the Antelope Valley, inferences have to be drawn from the Edwards AFB data and from larger regional studies of the Mojave Desert. In 1997, Earle et al. used climate modeling techniques to recreate probable Quaternary paleoclimatic shifts within Edwards AFB and the Antelope Valley. The resulting climate model for the Antelope Valley looks similar to that discussed above for the greater Mojave Desert with several significant variations. These variations between the models may be the result of differences in the modeling methods or may indicate that the effects of large climatic shifts can vary significantly on a local level. Overall, the Antelope Valley model shows a pattern of increasing temperatures with associated decreasing precipitation stretching from the Late Pleistocene to the middle Holocene followed by a cooling period of increased precipitation in the First Neoglacial period and variable, net decreasing precipitation and rising temperatures in the Late Holocene. The results of the Antelope Valley climate model along with other Antelope-Valley specific information are presented below. Late Pleistocene 17,750 to 14,750 BP The Antelope Valley model indicates that there was a period of decreasing rainfall between 17,750 and 14,750 BP that resulted in a precipitation decrease of 10% on Edwards AFB, 16% in the San Gabriel Mountains and 12% in the Tehachapi Mountains. This was followed by a period of high variability between 14,750 and 12,100 BP that resulted in a net precipitation decrease of 3% on Edwards AFB, 8% in the San Gabriel Mountains and 8% in the Tehachapi Mountains (Earle et al. 1997). This decrease in precipitation corresponds to the overall warming trend seen in the Mojave Desert model following the Last Glacial Maximum in the Late Pleistocene. In the Late Pleistocene, Lake Thompson dominated much of the eastern Antelope Valley between at least 30,860 and 17,600 BP. At its peak, the lake stretched from Rogers Dry Lake in the north of the valley (current Edwards AFB) to Lancaster in the south (Figure 8). Lake Thompson was fed by seasonal runoff from the San Gabriel and Tehachapi Mountains. Runoff was transported in drainages that are still in existence today including Big Rock, Little Rock, Amargosa, Los Alamos, Cottonwood, Oak, and Mohave Creeks. At its highest point, the lake reached 710 meters AMSL and occasionally spilled over into the Fremont Valley to the North. The peak levels were between 24,000 and 17,000 years ago (Mehringer 1977; Orme and Yuretich 2004), and there may have been several high water stands that have not been defined for Lake Thompson. By 17,000 BP, Lake Thompson began a final desiccation and appears to have been completely dry within a few millennia, although the exact date of desiccation is unknown. There is evidence that during the time period between the Last Glacial Maximum and the Pleistocene/Holocene Transition, a shallow perennial Lake Thompson appears to have persisted, until around 12,600 BP. (Orme 2008; Orme and Yuretich 2004).

Pleistocene Lake Thompson Regional Location Pleistocene-Holocene Transition (12,100 to 10,100 BP) Between 12,100 and 10,100 BP, the Antelope Valley climate model indicates that temperature increased dramatically and another, more drastic drop in precipitation took place. During this time period, precipitation dropped by 31% at Edwards AFB, 47% in the San Gabriel Mountains, and 30% in the Tehachapi Mountains (Earle et al. 1997). This differs from the greater Mojave Desert model, which, among oscillating temperatures following the Last Glacial Maximum, saw a general cooling trend and a return to near glacial conditions during this period associated with the Younger Dryas. Vegetation in the Antelope Valley during this period transitioned from woodland to desert scrub. Based on pack rat midden plant data from Searles Lake, China Lake, and Las Vegas Valley (in areas to the north and east of Antelope Valley), woodlands were replaced by creosote bush and desert scrub after 12,100 years ago in the eastern Antelope Valley (Rhode and Lancaster 1996). Early Holocene (10,100 to 8,100 BP) The early Holocene was marked by mild temperature and rainfall variability and an overall precipitation drop of 5% on Edwards AFB, 4% in the San Gabriel Mountains, and 1% in the Tehachapi Mountains (Earle et al. 1997). Middle Holocene (8,100 to 4,300 BP) The Middle Holocene, between 8100 and 4300 BP, once again saw fluctuating precipitation and temperatures with an abrupt temperature spike around 7900 BP and a precipitation spike around 6300 BP. Overall this period saw a 24% loss of precipitation on Edwards AFB, a 43% loss in the San Gabriel Mountains, and a 23% loss in the Tehachapi Mountains (Earle et al. 1997). This net decrease in precipitation corresponds with the general warming trend in the Holocene Maximum. Based on data from other parts of the Mojave Desert, the modern plant communities of the Antelope Valley were likely established during this time period, between 5,000 and 4,500 years ago (Koehler and Anderson 1998; West et al. 2007). Creosote was fully established by 5,500 years ago on Edwards AFB (Rhode and Lancaster 1996). The Lake Thompson basin likely had periodic infill events throughout the early and middle Holocene although the number and levels of these are unknown. The Lake Thompson desiccation moved eastward as the climate warmed and precipitation decreased, eventually breaking up into Rogers, Rosamond, and Buckhorn Lakes around 8,000 years ago (Thompson 1929). At least one partial infill event of the Lake Thompson basin may have occurred during the Mid-Holocene as evidenced by barrier beach ridge deposits west of Rosamond Lake dated to 6830 BP (Orme and Yuretich 2004). Late Holocene (4,300 BP to Present) The Late Holocene is marked by periods of temperature and rainfall variability. The Antelope Valley model shows a cool and moist period between 4300 to 1900 BP (Earle et al. 1997). During this period the precipitation increased by 17% at Edwards AFB, 43% in the San Gabriel Mountains, and 17% in the Tehachapi Mountains. After 1900 BP, temperatures warmed and precipitation was reduced to pre4300 BP levels, reaching a low during a hotter and dryer period circa 300 BP (Earle et al. 1997). Archaeological Research Design for the Antelope Valley Study Area 142 07A3822 Task Order 17 According to the model, peaks in precipitation occurred around 3900 and 1900 BP. The climate model for the Antelope Valley varies from that of the greater Mojave Desert. The model for the Mojave Desert shows a high degree of variability within the Late Holocene, as does the Antelope Valley model. Both models show a wetter cooling period between 4,000 and 2,000 BP associated with the First Neoglacial followed by a hot dry period associated with the Medieval Climatic Anomaly. However, the larger Mojave Desert model includes a cooler, wetter period between 600 and 150 BP associated with the Little Ice Age; in contrast the Antelope Valley model indicates a precipitation drop around 300 BP. Vegetation in the Antelope Valley was similar to that seen today. Mesquite was established in the Antelope Valley around 4300 years ago (Schroth 1987). Later in time, during the ethnohistoric period (later part of Little Ice Age), Joshua tree and Prosopis spp. (mesquite) were important food plants. Based on data from Edwards AFB, it is assumed that there were no major changes in vegetation of Antelope Valley from Middle Holocene to present day (Rhode and Lancaster 1996). During the Late Holocene through modern era, the remnants of Pleistocene Lake Thompson, consisting of Rosamond, Buckhorn, and Roger’s Lakes, intermittently filled with seasonal water runoff during heavy rain years and major flood events. During this period small playa basins and stable dunes along the margins of Rosamond and Rogers dry lakes provided natural catch basins for water runoff and rainfall from areas throughout the Antelope Valley. These small ponds were able to retain water for relatively long lengths of time, attracting birds and sustaining plant growth (Norwood 1989). In addition, prior to the arrival of Europeans, the water table was high within the Antelope Valley, leading to multiple springs, seeps, and marshes throughout the valley (Sutton 1988b). Research Questions and Data Needs Paleoclimate of the Antelope Valley The following three questions and data requirements pertain to reconstructions of the paleoclimate of the Antelope Valley. Questions 1) What are the number, timing, and extent of the various infill events associated with Lake Thompson and its residual lakes, Rosamond, Rogers, and Buckhorn? Lake Thompson began its final desiccation following the LGM around 17,000 BP and there is evidence of a shallow perennial lake until around 12,600 BP. In the fluctuating climatic conditions that followed the LGM, Lake Thompson likely experienced intermittent infill events that may have persisted for up to several hundred years before drying again. There was likely at least one partial infill event of the Lake Thompson basin around 6830 BP. However, evidence of additional infill events, their depth, shorelines, and timing, is lacking from the known record. Archaeological Research Design for the Antelope Valley Study Area 143 07A3822 Task Order 17 2) How did the six major Late Pleistocene and Holocene climatic events affect the Antelope Valley? Do the effects of these regional and global climatic shifts vary significantly on a local level? The two climatic models reported here, for the greater Mojave Desert and the Antelope Valley, have several discrepancies. One important difference is the precipitation during the Little ice Age because the Antelope Valley model shows a precipitation low during the global cooling trend associated with the Little Ice Age, but the Mojave Desert model does not. Are these discrepancies an effect of differing methods used to derive the models or do they indicate that regional and global climatic changes did have variable effects at the local level? If the differences are proven to be accurate, these regional variations have important implications for settlement patterns in the Mojave Desert in general. 3) How did climatic changes affect the availability of resources (e.g., water, vegetation, and fauna) within the Antelope Valley? Did the presence of the high water table, perennial springs, and seeps during pre-contac times buffer the effects of the climatic shifts? Climate studies have indicated that climate in the Antelope Valley has fluctuated between cooler, wetter periods and hotter, dryer periods. These have been accompanied by an upland shift in woodland vegetation and intermittent lake infill events. The high water table and presence of perennial springs may have helped buffer the effects of these shifts, allowing plants, animals, and humans to occupy otherwise uninhabitable portions of the valley during dryer periods. Data Needs Identifying lake stand and infill events will require trenching, coring, and other geological studies tailored toward identifying and dating individual laminated lakebed surfaces, and lakeshore formations (i.e., creek delta deposits and beach deposits). Additional paleoclimate studies can be used to identify the specific effects of major climatic events on the Antelope Valley and, in turn, to predict the availability of resources within the Valley through the Late Pleistocene and Holocene. Determining the effects of springs and seeps on the inhabitability of the valley during dry periods will require determining the periods that springs were active and researching their use through time. Dating tufa rocks deposited by springs (where present) using uranium or radiocarbon dating techniques may be able to indicate the time period and duration that the springs were active. In addition, archaeological evidence from spring sites may be used to indicate whether or not areas around the springs/seeps were occupied during drier climatic periods. Studies of pollen, phytolith, and macrobotanical specimens can be used to provide insight into vegetation communities. Vegetation in the Antelope Valley All reconstruction of past vegetation is based on data from the Central Mojave, Northern Mojave and Eastern Mojave Desert areas. There is little or no paleo-vegetation data from the Antelope Valley. Therefore, it is imperative that future archaeological and paleoenvironmental studies in the Antelope Valley should include investigations tailored to address research questions about the paleoclimate with a focus on the paleovegetation. Archaeological Research Design for the Antelope Valley Study Area 144 07A3822 Task Order 17 4) Is piñon-juniper woodland vegetation the primary vegetation prior to 12,000 years ago in the Antelope Valley, including the playas and foothills? If so, how did the geo-topography of the Antelope Valley (a basin that slopes slightly from west to east) affect the vegetation? How did changing lake levels in Lake Thompson and its successor remnant lakes affect vegetation in the eastern Antelope Valley? Paleobotanical remains from pack rat middens outside Antelope Valley have revealed that much of the Mojave Desert, north and east of the Antelope Valley, had piñon-juniper woodland vegetation prior to 12,000 years ago. However, no such studies have taken place in the Antelope Valley. Antelope Valley has playas and foothills and it would be critical to understand if this part of the western Mojave Desert also had similar vegetation. For example, Koehler et al. (2005) have suggested that woodland vegetation may have been present in the southwestern part of the Mojave Desert as late as 7,800 years ago (Altithermal), followed by a transition to desert shrub vegetation. Lake Thompson had peak water levels between 24,000 and 12,000 years ago (Mehringer 1977). After 12,000 years ago when the climate became drier and warmer, there were some high lake stands (between 14,500 and 8000 years ago) that could have occurred at Lake Thompson (based on data for Lake Mohave). Research should address if and how these periodic higher lake levels affected the vegetation in the Antelope Valley. 5) Given that the elevation of the Antelope Valley is somewhat higher than the Central Mojave Desert, does the reconstruction of the evolution of vegetation for the Central Mojave Desert apply to the Antelope Valley? Did the Pleistocene vegetation associations persist for a longer period into the Holocene in the Antelope Valley? This research issue is related to the previous question, in that all reconstructions for paleovegetation in the Antelope Valley are based on data from outside the area, despite the valley being at a high elevation. 6) Data from Edwards AFB in the northeastern part of the Antelope Valley indicate that woodlands were replaced by creosote bush and desert scrub after 12,000 years ago, and that creosote bush was the dominant vegetation by 5,500 years ago. Was the timing of these changes in vegetation similar in other portions of the Antelope Valley? As dry conditions increased in the Mojave Desert with the Late Pleistocene-Early Holocene transition, the piñon-juniper woodlands retreated to the uplands and mountains, and more arid vegetation replaced the woodlands. This reconstruction has been applied generally to the Antelope Valley; however, there have been no investigations to document this change in the Antelope Valley, and also no data on the pace of this change in the valley foothills versus the playas. The variation and pace would have important implications to human settlement and adaptations. 7) Based on data from Edwards AFB, and from the Northern and Central Mojave Desert, it is assumed that there were no major changes in vegetation of Antelope Valley from middle Holocene to present Archaeological Research Design for the Antelope Valley Study Area 145 07A3822 Task Order 17 day. Can this be confirmed with studies in the valley? Or are differences expected based on differences in elevation? Several scholars (Mehringer 1977; Rhode and Lancaster 1996; West el al. 2007) have concluded that the Mojave Desert vegetation became similar to that of today during the Middle Holocene, although there are regional differences. However, very little is known about vegetation during the MCA and Little Ice Age. Future research should address the character of vegetation during the MCA and Little Ice Age specifically in the Antelope Valley. Furthermore, it should examine how changes may have been different, depending on variations in elevation in the Antelope Valley. Micro-climatic changes in the Antelope Valley would have a profound effect on changes and continuity of vegetation. 8) What is the timing of initial establishment of historically identifiable plant communities? Today, Antelope Valley is primarily characterized by saltbush scrub and creosote bush scrub vegetation on the valley floor and lake bed, with juniper/yucca/ on the foothill slopes that frame the valley. It would be important for archaeological interpretations to have a fine-grained reconstruction that defines the precise timing of when the saltbush and creosote bush scrub vegetation dominated the valley floors (after the movement of juniper woodland to higher elevations). 9) What effects from variations in aridity are discernable on the west-east movement of plant community ecotones? Piñon juniper woodland that covered much of the Mojave Desert in the late Pleistocene-Early Holocene was replaced by desert thermophiles; furthermore, the piñon and juniper moved upslope as the temperatures increased. This pattern has not been specifically studied in the Antelope Valley. Research should focus on collecting data to investigate if and at what pace the westward movement of piñon and juniper occurred in the valley; and the timing of the disappearance of the woodlands from the valley floor. 10) What resources were available to hunter-gatherer populations through time as a result of changes in ecosystems? Fine-grain analysis of vegetational changes in the Late Holocene is needed to study the range of plant resources that would have been available to human populations and to see if there were vegetation changes in micro-niches in the Antelope Valley that would have had a direct effect on human adaptation. The fine-grain vegetational reconstruction for the Late Holocene in the Antelope Valley also has implications for which animals would have been supported in the environment. 11) What possible effects or influence did human populations have on ancient ecosystems? Humans have unintentionally and/or intentionally have had an often-irreversible influence on ancient ecosystems. For example, Spanish colonization of California resulted not only in devastating cultural change to the Native Americans, but also had immense effects on the native vegetation which in turn had an effect on how some animal populations changed their grazing areas and migration patterns. The introduced plants replaced native grasses and ultimately imbalanced the ecosystem (Minnich 2008). The effect of such colonizing plants on Antelope Valley vegetation as a result of EuroArchaeological Research Design for the Antelope Valley Study Area 146 07A3822 Task Order 17 American contact will provide valuable insight into how the change in vegetation could have impacted the adaptations of the Native Americans. In addition, some plants like Filaree (Erodium circutarium) came into California prior to the colonial period, and current understanding is that they may have been brought in by migratory birds and animals (Scott and Byrne 1998). Data Needs Very specific paleovegetation data is needed to address the research questions identified above. These data include paleobotanical samples from pack rat middens with good chronological control, and pollen samples from sediment cores from preserved cut banks with deep and well-distinguished stratigraphy. In addition, these samples should be obtained from a variety of settings: valley floors, playas, and foothills, to best reconstruct changes in vegetation by elevation over time. Archaeological Research Design for the Antelope Valley Study Area 147 07A3822 Task Order 17 Theme: Settlement Patterns and Social Organization Theoretical orientions and methods for studdying settlement patterns are presented in the approximate order they were developed, followed by a reconstruction of possible settlement patterns and social organization by time period for the Antelope Valley. Settlement Patterns and Settlement Systems One of the earlier definitions of settlement pattern studies was offered defined by Willey (1953:1) in the introduction to the report of a survey of the Viru Valley, Peru. He defined such studies as the way in which humans occupied and exploited the physical landscape. Settlement pattern studies refer to: dwellings, to their arrangement, and to the nature and disposition of other buildings pertaining to community life. These settlements reflect the natural environment, the level of technology on which the builders operated, and various institutions of social interaction and control which the culture maintained. As with the Viru Valley study, most settlement pattern studies undertaken during the 1950s and 1960s were conducted in areas previously occupied by agricultural societies and which included the remains of structures and dense surface distributions of ceramics. Parsons (1972) discussed the problems of sampling, refining chronology, and paleoenvironmental reconstruction in settlement pattern studies. Adequate sampling was necessary in order to “measure the full range of regional variation in a number of key variables, including both archaeological and environmental features” (Parsons 1972:146). In order to study settlements, it is necessary to demonstrate the contemporaneity of archaeological features. Paleoenvironmental reconstruction is necessary in order to study the distribution of past settlements in relation to the distribution of available resources. The concept of settlement system emerged from studies in economic geography in Germany during the 1930s. The goal of these studies was to explain locational patterns and functional interdependence between towns and surrounding areas. Settlement systems in archaeology were first discussed by Howard D. Winters in his dissertation on the Riverton Culture of Illinois, later published as a monograph (Winters 1969). Winters distinguished between settlement pattern and settlement system. Settlement patterns refer to "the geographic and physiographic relationships of a contemporaneous group of sites within a single culture" (Winters 1969:110). However, in order to describe a settlement system, "the functional relationships among the sites contained within the settlement pattern" must be specified (Winters 1969:110). Winters (1969:111) noted that information on seasonality ("degree of permanence in habitation"), technology, features, and subsistence pattern are necessary to begin to describe the settlement system. A more detailed discussion of the settlement system concept has been provided by Parsons (1974:83) who, following Winters (1969), defined a settlement system as "functional relationships of Archaeological Research Design for the Antelope Valley Study Area 148 07A3822 Task Order 17 sites within a region." Parsons (1974:83) provides an example of a simple settlement system which might consist of: a large base camp, where all the population of an area spends much of its time during an annual cycle, together with a series of smaller camps where small groups of people from the main base camp live for shorter periods while they are away from the main camp on seasonal hunting expeditions, etc. Parsons (1974:83) defines four parameters which must be specified in order to adequately reconstruct a settlement system. These are: 1. the limits of the settlement system; 2. the spatial distribution of occupation (settlement pattern); 3. the contemporaneity of occupational remains; and 4. the functions of occupational loci. In most cases, the limits of the system are difficult to establish but are likely to correspond to a group’s territory. The spatial distribution of occupation refers to the location of sites with respect to topographic features (e.g., near mouths of canyons) and resources (e.g., acorn gathering areas). The third parameter, contemporaneity of occupational remains, refers to the span of time that each site was occupied. Ideally, the goal is to reconstruct the settlement system at specific points in time. Reconstruction of settlement and subsistence requires the development of a detailed and comprehensive chronology of sites and activity areas within sites to determine if sites were contemporary and could have functioned as part of the same system. At a more detailed level, it is also necessary to determine whether activity areas within sites were in use at the same or different times. Related to this is the problem of seasonality. Some sites were probably occupied only for a season or part of a season during any specific yearly cycle and, therefore, were not occupied at the same time of the year as other sites used during other seasons. One of the most challenging problems in archaeological research is determining the function of occupational loci, the fourth parameter listed previously. This problem "lies at the very heart of settlement systems analysis" (Parsons 1974:83). At each site or occupational locus within a complex site, certain activities were performed. Reconstructing these activities is a major goal of settlement systems analysis. Foragers and Collectors Binford (1980) proposed a continuum of hunter–gatherer adaptive strategies, known as the foragercollector model, for coping with unfavorable mixes of population and resources in space (too many people or too few resources at any given place) or time (too many people or too few resources in a season). When resources are fairly abundant everywhere, but can become exhausted in any one location, the group moves to a new location where resources are more abundant. Thus, foragers move the local group to the resources (residential mobility). However, if environmental productivity Archaeological Research Design for the Antelope Valley Study Area 149 07A3822 Task Order 17 is low and resources are distributed differentially, task groups go out to collect different kinds of resources at greater distances from the main settlement (residential base) and bring them back to the group. Thus, collectors move resources to the group (logistical mobility). According to Binford (1980), these differing strategies of resource procurement should produce distinct patterns in the archaeological record with regard to site types. For foragers (residentially mobile groups), at least two associated site types are expected: the residential base and the location. Residential bases were defined as places where a wide range of activities occurred associated with everyday living, and included “most processing, manufacturing, and maintenance activities” (Binford 1980:9). Locations were nearby sites where specific resources would have been obtained but minimally processed. For collectors (logistically mobile groups), Binford identified three additional site types in addition to residential bases and locations: field camps (or temporary camps), stations, and caches. Field camps (temporary camps hereinafter) were defined as temporary encampment areas located where the distance from the residential base required overnight stays by the task groups that used them. Stations were information-gathering sites (mostly used by hunters), and caches were temporary storage localities for large bulk items. (See below for more information on these site types.) Foragers typically operate out of a residential base which is frequently moved as resources around the residential base are depleted. The forager strategy is successful only if the necessary resources are always available from each new residential base. If this kind of relatively uniform distribution of resources is not present, a collector strategy may be more efficient. Collectors occupy residential bases which may be moved only a few times a year or not at all. Small specially organized task groups are sent out from the residential base to collect resources. Thus, one task group may go out to collect one resource located in one direction from the residential base, while another may travel in the opposite direction to collect another. These task groups may stay overnight away from the base camp, establishing field camps (temporary camps), a site type not found among foragers. Collectors also practice food storage while foragers usually do not. Large quantities of a seasonally available and storable resource, such as acorns, can be brought back to the residential base by collectors and stored for later consumption during seasons when fewer resources are available. Storage promotes maintaining the residential base in the same location (greater sedentism) in order to access the stored resources and increases even greater reliance on logistical procurement. The differences between foragers and collectors should be represented as a continuum, not a dichotomy. Many groups practiced elements of both strategies. In many cases, the kind of settlement-subsistence strategy employed by a group varied with the season. When resources were abundant throughout the area, the group may have followed a forager strategy (residential mobility), but when resources of different kinds were less abundant and were available only in certain dispersed locations or only in a certain season, they may have pursued a collector strategy (logistical mobility). Archaeological Research Design for the Antelope Valley Study Area 150 07A3822 Task Order 17 Binford's (1980) causal model for the development of a logistic pattern was based on climate: the colder the effective temperature, the more a group would have to rely on stored foods during the less productive part of the year. However, this model does not account for the presence of many logistically organized societies in the temperate zones of the world. Hayden (1986) contends that logistic strategies are adaptive for procuring r-selected resources. R-selected resources have short reproductive cycles and produce large numbers of offspring, each of which individually is a small food package. Examples are seeds, nuts, fish, birds, and small mammals. This contrasts with kselected resources which have long reproductive cycles and produce few, but relatively large, offspring which are protected by their parents. Most k-selected resources are large mammals such as elk, bighorn sheep, deer, bear, mountain lion, etc. While r-selected resources are abundant and reliable, they have much higher processing and storage costs. Thus, a logistic settlement system with storage and a semi-sedentary settlement pattern is an adaptation to expending additional energy to harvest large amounts of storable r-selected resources on a reliable basis. Foragers, on the other hand, are opportunists and generalists who exploit limited, scarce, and unpredictable resources, usually k-selected large mammals in combination with large package plant foods such as tubers and some r-selected resources which do not require a great amount of processing time and which are usually not stored. Thomas (1983) proposed a simple scheme of three settlement strategy models for the Great Basin based on ethnographic examples. The first settlement strategy is characterized by fission, small groups foraging throughout a territory in a seasonal round. This is similar to the forager end of Binford's forager-collector continuum. A second strategy is characterized by fission-fusion where the group maintains a central base for part of the year and breaks up into smaller mobile groups the rest of the year. This strategy combines collector and forager strategies. The third strategy, fusion, is characterized by a semi-permanent village to which collector parties bring back resources. The fusion model is at the collector end of Binford's continuum. The three settlement strategies proposed by Thomas (1983) are influenced by resource distribution. The storable resource available in the Great Basin region studied by Thomas is pinyon pine nuts. The degree of sedentism is directly related to the abundance and spatial relationship of this resource to other resources. Groups practicing a fission strategy have sparse dispersed pinyon groves located at a distance from other resources. At the other extreme, groups practicing a fusion strategy, such as in the Owens Valley, have dense stands of pinyon directly adjacent to Valley resources, such as seeds. Thomas (1983:76-81) has provided a detailed set of expectations for sites generated by collectors in the Great Basin. Residential bases established by collectors are located near food, water, and fuel, and have characteristic structures, facilities, and artifact assemblages. Structures and facilities include houses (usually randomly distributed), sweat houses, cache or storage features, cemeteries, public space, a debris disposal area, and food procurement facilities such as dams and weirs. The artifact, floral, and faunal assemblage includes: Archaeological Research Design for the Antelope Valley Study Area 151 07A3822 Task Order 17 1. food preparation and consumption tools; 2. food preparation and consumption by-products (hearths, faunal and floral remains); 3. tools for making and repairing other tools, raw materials, and by-products; 4. stored and cached food and raw materials; 5. children’s toys; and 6. luxury, ceremonial, recreational items. Residential bases have evidence for intentional planned tool production. All lithic production stages are represented for local raw materials. Tool production debris and food waste are usually so abundant such that they are disposed of in secondary refuse areas. Floral and faunal remains exhibit higher richness (more species) compared to other site types. Field camps or temporary camps are "temporary centers of operation for special purpose task groups" (Thomas 1983:79). They are usually established to obtain either plants or animals, but not both. Temporary camps are task specific and usually occupied for a short period of time varying from one or two nights to two to three weeks. Caves and rockshelters are often used as temporary camps (Thomas 1983:80). The artifact assemblage consists of specialized implements for resource procurement and extraction. The initial stages of tool production are usually not represented. Food consumption may consist of "snacking" on less desirable faunal parts which are not transported back to the residential base. It should be expected that temporary camps would exhibit little internal structure since these locations were likely used for short periods and for specific purposes. The remains at these camps should represent a relatively narrow range of activities, likely focused on the procurement of very specific resources (Binford 1980). Other site types associated with collectors include caches and locations. Caches are where food or artifacts are stored for use in another season or for the next time that environmental zone will be visited. Items for trade may also be cached, which reduces the transport cost. Locations are where food and other resource procurement activities take place. They may include hunting blinds, fishing weirs, and places where seeds and nuts are collected. The logistic strategy has characteristic concentric bands of activities centered on the residential base (Thomas 1983:88). The campground radius extends out about 1 km from the residential base and is the zone in which firewood, water, raw material for manufacturing, and plants for medicine are collected. The foraging radius extends about 10 km from the residential base and is systematically exploited by task groups from the residential base. Locations are found within the foraging radius. Temporary camps are established in the logistic radius beyond 10 km where specialized task groups stay overnight instead of returning to the base camp because of the distance involved. Archaeological Research Design for the Antelope Valley Study Area 152 07A3822 Task Order 17 Internal Site Structure Archaeologists have tried to study internal site structure of hunter-gatherer sites by looking at the spatial distribution of functional artifact types to reconstruct activity areas. However, ethnoarchaeological studies have shown that assumptions made by archaeologists in defining activity areas may be in error (Kroll and Price 1991). Ethnoarchaeological studies have shown that it should not be assumed: • • • that sites are divided into activity-specific areas that artifacts reflecting particular activities were produced in proportion to the frequency with which particular activities were performed, or that refuse is deposited at or near where it was produced. Thus, it cannot be inferred that “objects found together in archaeological context, however consistently, were used together in the same activity in the past” (O’Connell 1987:105). An ethnoarchaeological study of the Alyawara, mobile hunter-gatherers in Australia, found that most activities conducted by a household took place in household activity areas in and around a house. Some activities took place in peripheral areas when shade or other variables were better at those locations. When an Alyawara residential base is seen as an archaeological site, several large clusters of refuse are present, each marking the location of a household area with their adjacent specialactivity areas and secondary refuse areas. The refuse clusters, which mark the remains of these household areas, display little internal structure and most clusters contain similar artifacts and food waste. While site structure appears to be simple and undifferentiated among mobile foragers, site structure may be more complex among semi-sedentary collectors who practice food storage (O’Connell 1987:105). An ethnoarchaeological study of the modern Basarwa of southern Africa showed that as residential mobility decreased, the abundance and diversity of debris left in a site increased, as did site size and the number of storage features (Kelly 1992). In addition, the sedentary Basarwa used secondary trash dumps located farther from houses, rather creating refuse deposits in and around household areas which is characteristic of the mobile Alyawara. Study of CA-ORA-662, a Late Prehistoric site in the San Joaquin Hills of Orange County (Mason 2008), provides confirmation that residential bases of collectors have a more complex internal site structure. Large amounts of food waste consisting of animal bone and shell are distributed around fire-affected rock features in the southern part of the site which indicates that food processing and general residential activities took place there. A location for secondary refuse dumping was in the central part of the site. High counts of lithic debitage and lithic and shell manufacturing tools and artifacts were found to the north of the refuse dump, suggesting a work area. This provides archaeological corroboration from a site in southern California that residential bases of collectors have a more complex, internally differentiated site structure compared to those of mobile foragers. Archaeological Research Design for the Antelope Valley Study Area 153 07A3822 Task Order 17 Mobility The study of hunter-gatherer settlement systems includes looking at mobility strategies which refer to “the nature of the seasonal movements of hunter-gatherers across a landscape” (Kelly 1983:277). The mobility strategies discussed by Kelly (1983, 1992, 2007) are mostly based on ethnographic studies of modern hunter-gatherers. Hunter-gatherer mobility strategies are related to the distribution of food resources in the environment and are based on Binford’s (1980) discussion of residential mobility (foragers) and logistical mobility (collectors). There are different variables to consider for residential mobility strategies versus logistical mobility strategies (Kelly 1983:278-279). The key variables for residential mobility are: 1. number of residential moves per year; 2. average distance per residential move; 3. total distance covered through residential mobility per year; 4. total area covered per year; and 5. length of occupation of a winter (or rainy season) site. The key variables for logistical mobility are: 1. the average one-way distance covered between a residential base and a field camp (temporary camp); and 2. the average total duration for a round-trip from a residential base to a field camp. The residential mobility variables, such as number of residential moves per year and average distance per residential move, are influenced by the distribution of food resources which are affected by environmental variables including primary biomass, effective temperature, and rainfall. Resource accessibility is based on resource dispersion, size, and location. Because many plant and animal resources are only available during particular seasons or for limited periods of time, resource monitoring is often necessary to determine where and when a resource is most abundant. Resource monitoring may include the availability of water, especially in desert environments. When foragers decide to move their residential base, the location to which they decide to move may be based on the results of resource monitoring (Kelly 1983). Long-term mobility refers to variations in mobility strategy over many years or decades. As the availability and distribution of resources change due to environmental change (a period of drought, for example), mobility strategies can change as groups exploit other nearby areas and different resources (Binford 1983; Kelly 1992). Optimal foraging theory provides a framework for understanding the relationship between the degree of hunter-gatherer mobility and subsistence strategies. Foragers move their residential base to a new location when the availability of resources within the foraging radius around the residential base reaches a point of diminishing returns. This occurs when the amount of food available near the residential base declines and people have to travel greater distances from the residential base to find food. At this point, it is easier to move the residential base to a new location where resources are Archaeological Research Design for the Antelope Valley Study Area 154 07A3822 Task Order 17 more abundant or less costly to obtain. However, as the cost of moving the residential base increases relative to the benefit of foraging in a new location, foragers will remain longer in the current residential base. Thus, the decision to move is based on the costs of foraging around the residential base (including travel time to the resource and transport time to bring the resources back) versus the cost to move the residential base to the new location, as well as the perceived benefits of the greater availability of resources at the planned new residential base location (Kelly 1992). If it is not certain that resources will be more abundant at the new location, the risks involved with moving to the new location increase the cost of moving and the group may stay longer at the original residential base. Variables other than obtaining food can affect foragers’ decisions to move. In a desert environment, water availability is an important factor in deciding when to move. A group may decide to stay near a known water source longer rather than moving to a different water source where the availability of water is uncertain (Kelly 2007:145). Other variables can include gaining access to firewood or lithic raw materials, to avoid annoying insects, or moving for social or political reasons, such as to seek spouses, allies, or shamans, or to move in response to sorcery or death (Kelly 1992). Collectors move their residential base less often than foragers and may be entirely sedentary (remaining in the same residential base or village year-round). Sedentism may be seen as a process in which human groups reduce their mobility, making fewer and fewer residential base moves within a year until they reach a point where they remain residentially stationary year-round. However, sedentary settlement systems may include those in which only part of the population remains at the same location throughout the entire year (Kelly 1992). Hunting or foraging parties may leave the residential base and return later with procured resources. Two contrasting hypotheses have been proposed for the causes of sedentism, known as the “pull” hypothesis and the “push” hypothesis (Kelly 1992). In the pull hypothesis it is assumed that if resources are abundant in a particular location, the result will always be sedentism. It was assumed that sedentism was a more efficient means of resource procurement because it saves the cost of moving. The localized abundant resources which acted as a pull to sedentism were thought to be marine resources, wetlands resources, and agricultural resources. However, there are many examples of groups that relied on agriculture but were still mobile. For sedentary hunter-gatherers in California, the localized abundant resources were plant foods which could be stored. The pull hypothesis may not be a good explanation for sedentism because abundant localized resources may not reduce mobility (Kelly 1992). In the "push" hypothesis hunter-gatherers are forced into sedentism by subsistence stress (a shortage of food supply relative to population size) which results in intensification of resource procurement, taking a greater range of foods and spending more time in harvesting and processing them. Often the harvested foods are then stored, which provides abundant food at a single location, resulting in sedentism. Intensification may be caused by population increase, climatic change, and territorial constriction. For mobile groups, costs are associated with moving the residential base. For sedentary groups costs are associated with intensification. The costs of moving may increase Archaeological Research Design for the Antelope Valley Study Area 155 07A3822 Task Order 17 unacceptably if regional population density is high and if, in order to move to a new location, it is necessary to displace another group (Kelly 1992). Hunter-Gatherer Settlement and Social Organization in California Bettinger (2015) suggests that “hunter-gatherer [resource] intensification is as much a social phenomenon as a subsistence phenomenon” (Bettinger 2015:30). A well-documented regional sequence of settlement systems (mobility strategies) and subsistence systems (interaction between technology and food resources) is necessary to develop models for the shift to greater intensification (more intensive use of resources). Bettinger (2015) uses the well-documented regional sequence for the Owens Valley of eastern California in his discussions. Intensive hunting and gathering developed in the Owens Valley after circa A.D. 450 based on intensification of green cone pinyon (pine nuts) (Eerkens et al. 2004). Based on this hypothesis, population growth did not cause intensification (contra Basgall 1987 and Beaton 1991); population growth was a result of intensification. The trigger for the intensification of pine nuts among Owens Valley groups was the adoption of the bow and arrow circa A.D. 450. Prior to A.D. 450 groups were primarily mobile hunters using atlatls (spear throwers). Atlatls are inaccurate and can only be used at close range. The element of surprise is lost after the first shot. Therefore, multiple shots from a group of hunters are needed to take down a mountain sheep or even a deer. According to Bettinger (2015), group size was relatively large among hunters using atlatls, and meat was shared among the group (resource pooling to decrease subsistence risk). The uncertainty of large game procurement using an atlatl resulted in resource pooling (sharing) within large groups to reduce risk. Although the size of each group was relatively large, the regional population that could be supported by large game hunting was small, only about 13% of the ethnographic population (Bettinger 2015:41). Because the bow and arrow is silent, one person can take multiple shots without losing the element of surprise. The bow and arrow is also more accurate from a longer distance and can hit smaller prey. An individual hunter can be successful using a bow and arrow, and group size can be reduced to perhaps an extended family (a bilateral family band) with reduced mobility. Mobility can be reduced because an individual hunter with a bow and arrow can take large numbers of smaller game from a smaller area, instead of having to travel long distances with a group to hunt mountain sheep. In the Owens Valley the number of rabbits, hares, and marmots double in faunal assemblages after A.D. 600. With greater hunting success using a bow and arrow in the local area, there was less incentive to move. Archaeologically, this is reflected in a decreased number of temporary hunting camps after A.D. 600 (Bettinger 2015). With the decrease in residential mobility, plant procurement increased around the residential base. With the decreased availability of big game and the increased use of small mammals there was less fat in the diet. Fat and additional carbohydrates were instead obtained from plants. Thus, the Archaeological Research Design for the Antelope Valley Study Area 156 07A3822 Task Order 17 decrease in residential mobility led to intensified plant procurement and an increase in population after A.D. 600 (Bettinger 2015). The shift from larger groups to smaller groups of closely related people (likely a bilateral family band) made it possible to share within the small group plant foods that required more processing time compared to animals. In large groups “freeloaders” would want to take some of the plant foods after a great deal of labor was invested in processing them. It is likely that the freeloader would not be closely related to the individual who processed the food. In smaller groups of closely related people it is less likely that there would be freeloaders since everyone was closely related and the results of intensive plant food processing could be shared only among the members of the closely related group. Because of the freeloader problem, in large groups it is not likely that labor would be invested in intensive plant food processing when the products of that labor would have to be shared with others who did not work as hard. In smaller groups of closely related family members, people were more likely to invest labor in intensive plant food processing (Bettinger 2015). The transition from large groups of hunters to smaller groups of plant food processors initiated the change from travelers to processors originally described by Bettinger and Baumhoff (1982). By A.D. 1250 pinyon nuts were being stored in the Owens Valley. The social rules of food sharing changed so that stored food became private property. There would be no reason to store plant foods that required major processing work if the stored foods had to be shared outside the small group that processed the food. Storage of pinyon began relatively late in the cultural sequence because pinyon production was unreliable from year to year. Only 20% of pinyon groves were productive in a given year. Intensification of small seed use with private storage of seeds began about A.D. 1200 in Owens Valley. The combination of both intensive pinyon and seed processing and private storage of pinyon and seeds led to population increase and the establishment of Valley floor villages (sedentism) (Bettinger 2015). Because oak groves produce acorns more reliably and in greater quantities, privatized storage of acorns began earlier in central California compared to storage of pinyon in Owens Valley. Intensive acorn use in central California began between 2,000 B.C. and A.D. 1000, depending on the geographic area (Basgall 1987). Privatized storage of acorns probably began about A.D. 1000 in central California. The greater reliability of production of individual oak groves also led to private ownership of oak groves as well as the stored acorns. Intensification and storage of small seeds also took place (Bettinger 2015). The change in social rules regarding ownership of stored intensively processed plant foods and ownership of oak groves led to the need to defend them. The development of defended territories led to a change in social organization. The bilateral family band, which was composed of relatives of both the father and mother, changed into a small patrilineal exogamous band where only the males were closely related. A small group of related males using the bow and arrow could defend a territory of privately owned oak groves. As population grew, competition increased which increased the need for territorial defense, leading to the development of larger patrilineal exogamous sibs (a Archaeological Research Design for the Antelope Valley Study Area 157 07A3822 Task Order 17 patrilineage with great time depth) or clans (the term used among the Serrano) which could defend larger territories. The sib or clan was composed of a single lineage. The group of related males defended the products of female subsistence labor (the gathered and processed plant foods that were stored) and defended the territory against raiding by neighboring groups which may have had food shortages or whose water source (usually a spring) dried up (Bettinger 2015). Among most Takic-speaking groups in southern California, social organization stayed at the level of patrilineal sib or clan. However, among the Gabrielino and in central California, tribelets, composed of more than one sib or patrilineage, developed. Following Murdock (1949:208), Bettinger (2015:121) believes that changes in subsistence organization led to changes in social organization. In other words, privatization of stored foods and ownership of oak groves caused competitive pressures that led to the development of patrilineal descent groups (sibs). Thus, according to Bettinger (2015:124), southern California sibs or clans were the result of resource competition fueled by population growth. As an alternate to the model presented by Bettinger (2015), it is possible that the social organization based on exogamous patrilineages seen in the Mission Period was already present among the Takicspeaking groups when they arrived in the southern Antelope Valley. This type of social organization may have been a cultural characteristic of Takic-speaking groups. Each exogamous patrilineage (clan) may have established a territory upon arrival. Subsistence for these early Takic groups may already have been focused on small seeds. As population grew within the territory, seeds were stored. As population further increased, acorns, which produced large energy yields and could be stored, but also required large amounts of processing time (intensification), were added to the diet. Note that if exogamous patrilineages (clans) existed from the beginning, there would be no freeloader problem because the clan consisted entirely of a group of closely related males, so that sharing and storage would not cause conflict. In the first model, changes in the organization of settlement and subsistence (intensification and storage within a permanent residential base or village) led to changes in social organization (development of exogamous patrilineages or clans), as proposed by Murdock (1949) and Bettinger (2015). In the alternate model, territorial exogamous patrilineages are present from the beginning (in other words, this type of social organization was a cultural characteristic of Takic groups) and this led to population increase and circumscription, leading to subsistence changes (intensification and storage of plant foods). So, the question is, do changes in the organization of subsistence lead to changes in social organization, as proposed by Murdock and Bettinger, or does a specific kind of pre-existing social organization lead to changes in settlement and subsistence? Forager Versus Collector Settlement Organization: Archaeological Expectations The mobility strategies discussed by Kelly (1983, 1992, 2007) and others are mostly based on ethnographic studies of modern hunter-gatherers. It has been difficult to apply these ethnographically derived mobility strategies using archaeological data. In order to test hypotheses Archaeological Research Design for the Antelope Valley Study Area 158 07A3822 Task Order 17 about mobility and sedentism, the nature, distribution, and availability of both used and unused resources must be documented. Some archaeologists have argued that bifacial tools or cores are generally associated with frequent residential moves, while expedient flake tools and bipolar reduction are associated with infrequent residential moves. Others have suggested that a greater diversity of tools is associated with collectors. However, these relationships between stone tool technology and mobility have not been demonstrated and are seen by Kelly as “subjective, intuitive, and sometimes contradictory” (Kelly 1992:56). Based on the discussion above, three different variables may be used to distinguish degree of mobility/settlement organization of hunter-gatherer populations: (1) settlement organization and site structures, (2) food remains, and (3) artifact assemblages. Settlement Organization and Site Structures It has been hypothesized that the longer a location is inhabited, the more structurally complex it will be (O’Connell 1987:99–102). For residential bases, discrete clusters of features and associated middens within a site area are likely to represent the remains of household units. It is also assumed herein that the greater the size of individual household units and their distance from neighboring households are indicative of the length of time an area was occupied. Specifically, sites containing relatively large discrete clusters of household remains located relatively distant from other clusters within the site area would suggest longer periods of occupation when compared to sites with smaller and closely-spaced household clusters (O’Connell 1987). A wide range of activities are also expected to be represented in the archaeological assemblages of residential bases, as these are the principal settlements where groups are expected to have carried out most social, economic, and political activities. It is also assumed that secondary refuse areas, as well as resource storage areas, are more likely to be associated with longer-term occupation of a residential base. It is likely that there will be greater differentiation of internal site structure in residential bases of collectors compared to those of foragers, as indicated by the ethnoarchaeological studies of the Alyawara and Basarwa discussed previously. The presence of temporary camps may be particularly important in distinguishing between forager (residential mobility) and collector (logistical mobility) settlement systems. Temporary camps are characteristic of collector (logistical mobility) settlement systems of collectors and are usually not found in forager settlement systems. Temporary camps have little internal structure as they were used for short periods, and the remains at these camps should represent a narrow range of activities that are focused on the exploitation of specific resources (Binford 1980). Food Remains Optimal foraging theory indicates that as a hunter-gatherer group exploits the food resources surrounding a settlement, a point is reached in which there are diminishing returns from the optimal set of resources (higher-ranked food items) within the diet breadth (Kelly 1992). At this point, the group may choose to stay put and expand the foraging range to greater distances and add non-local as well as lower-ranked food items. This strategy is generally associated with logistically-mobile Archaeological Research Design for the Antelope Valley Study Area 159 07A3822 Task Order 17 populations (collectors). The strategy of a residentially-mobile group, on the other hand, would be to move the residential base to a more productive resource patch. Bettinger and Baumhoff (1982:487) suggest that broadening the diet (increasing diet breadth) is a higher-cost strategy that would make the most sense under conditions of high population density in relation to resources, when mobility would most likely be restricted. In contrast, moving to a new resource patch where more higherranked food resources are available would be the optimal choice when population density is low in relation to resource abundance, such that mobility would not be restricted. Archaeologically, this would mean that settlements associated with residentially-mobile groups should contain a low diversity of high-ranking resources and that would have been available in the immediate vicinity of the residential base. For logistically-mobile groups, residential bases should contain a high diversity of both higher- and lower-ranked resources. Some of these resources would also be non-local, i.e., obtained from areas outside of the group’s expected foraging radius (Kelly 1995). Artifacts Artifact assemblages from residential bases associated with populations practicing logistical or residential mobility should be varied and representative of activities associated with social, economic, subsistence, and political pursuits. Artifacts and features should be classified functionally in order to reconstruct activities (hunting, animal food processing, plant food processing, food preparation and cooking, shelter and sleeping, manufacturing or maintaining tools, storage, and other activities) and site types (village, residential base, temporary camps, locations [including lithic scatters], and other site types). There should be both a greater diversity of functional tool types and a higher density of tools in the residential bases of collectors compared to those of foragers. Antelope Valley Settlement Systems Settlement systems in the Antelope Valley are discussed by time period in the following sections. Because few studies of settlement systems have been conducted for the Valley, only a general discussion can be provided. Nevertheless, the hypotheses provided can be used to guide future research. Clovis Period (Fluted Point Complex) (12,000 to 9500 BC) The Clovis Period was an era of environmental transition between the late Pleistocene and early Holocene. The Clovis Period within the Mojave Desert is, thus far, represented exclusively by the Fluted Point Complex, big game hunters who used Clovis-style spear points (fluted projectile points, hafted to the end of a spear). These fluted projectile points include both Clovis points and Great Basin Corner-Notched points. Fluted points have been discovered along the shores of former pluvial lakes at China Lake Naval Weapons Station and Edwards Air Force Base. There are two sites at Lake China with Clovis points, along with Lake Mojave points. Thus, it is not known if the other artifacts at these sites are associated with Clovis or Lake Mojave. All other Clovis points in the Mojave Desert Archaeological Research Design for the Antelope Valley Study Area 160 07A3822 Task Order 17 occur as isolated surface finds (Sutton 2018). It is thought that the Clovis settlement system consisted of small mobile bands of hunters who followed big game herds (residential mobility). Lake Mojave Period (9,500 to 7,000 B.C.) During the warmer and drier Early Holocene Great Basin Stemmed series projectile points including Lake Mojave and Silver Lake points were used as darts with a spear-thrower (atlatl) for hunting artiodactyls (deer and mountain sheep). Ground stone implements occur in small numbers during this time (Warren 2002) and may indicate the addition of hard seeds in the diet. The Lake Mojave groups gradually adapted to a desiccating environment, resulting in shifts in technology and subsistence, with exploitation of additional ecozones. Sites along a beach ridge overlooking Rosamond Lake (a part of former Lake Thompson) appear to have been locations used by hunters during the Lake Mojave Period. Each site contains the same group of formed flaked stone tools which include projectile points, bifaces, and crescents. There was also a Lake Mojave Complex temporary camp or small residential base near Rosamond Lake (Chandler et al. 2010). The Lake Mojave settlement system appears to have consisted of small mobile groups of foragers (residential mobility) who hunted the smaller animals (deer and mountain sheep) present after the extinction of the Pleistocene megafauna, supplemented by a small amount of plant foods. In the central Mojave Desert around the Mojave Sink it has been suggested that small family bands moved throughout a large territory (up to 9,100 square miles) opportunistically (no fixed seasonal round). Occupation of any specific place was probably short-term and sporadic. Resource monitoring to determine the availability of food and water was likely necessary to decide where and when to move the residential base (Sutton 2018). In this large area there may have been only 500 people with a population density of 1 person per 18 square miles (Altschul et al. 1998:128). Pinto Period (8250 to 2500 BC) The Pinto Period was a time of increasing aridity during the Altithermal. Sites associated with this period are usually found in open settings, in relatively well-watered locales representing isolated oases of high productivity such as stream channels and springs. Increasing amounts of ground stone tools suggest increasing use of small seeds. Artiodactyl (deer and mountain sheep) hunting continued, but increasing aridity likely reduced the number of deer available. Small animals such as rabbit, rodent, reptile, and fresh water mussel resources are present in significant quantities. The artifact assemblage is similar to the Lake Mojave assemblage except that Pinto projectile points replaced Lake Mojave points and Silver Lake points, and crescents and engravers were no longer used. Drills were added to the assemblage and the number of ground stone tools increased (Warren 2002). Warren (2002:139) sees the shift in projectile point types and the increasing use of plant foods during the Pinto Complex as resulting from decreasing numbers of artiodactyls (deer and mountain sheep) during this warm, dry period. Archaeological Research Design for the Antelope Valley Study Area 161 07A3822 Task Order 17 In the Antelope Valley there was a Pinto occupation (based on two Pinto points and obsidian hydration measurements in excess of 10 microns) at the Lovejoy Springs site (CA-LAN-192) located about 15 km north of the mouth of Big Rock Canyon in the southern margin of the Antelope Valley (Price et al. 2009). Some 41 sites in the Antelope Valley region (including CA-KER-303, CA-LAN-82, and -298) were identified as having what appeared to be a Pinto Complex component, based on projectile point types or other temporally diagnostic data (Earle et al. 1997:127-129). There is little indication of occupation in most areas of the Mojave Desert during the latter part of the Pinto Complex (Warren 2002; Sutton et al. 2007) and Sutton (2018:50) hypothesizes that the Mojave Desert was abandoned after 5,000 BP (3,000 BC). However, the western and southern fringes of the Antelope Valley were likely somewhat less arid than the rest of the Mojave Desert at this time (see Paleoenvironment section) and these areas may have been occupied during the last 500 to 1,000 years of the Pinto Complex. Pinto Period site distribution appears to represent a continuing transitory pattern related to fluctuating and dispersed resources. Settlement systems may have consisted of small, mobile groups of foragers that moved among water sources (such as Lovejoy Springs) where they established residential bases for hunting or trapping small mammals and obtaining plant foods. Because water sources decreased during this warm dry period, the number of places where base camps could be established were limited and bands stayed longer at each residential base near a water source. Resource monitoring to determine the availability of food and water was likely necessary to decide where and when to move the residential base. The Pinto Period site distribution indicates the continuation of a forager settlement system with residential mobility. Gypsum Period (circa 2500 B.C. to A.D. 225) The Gypsum Period corresponds to the First Neoglacial Period (2,000 – 1 BC) when precipitation increased and temperatures decreased. This appears to correlate with increasing trade and social complexity (Sutton et al. 2007). The use of dart points (Elko and Gypsum points) with spear-throwers continued during the Gypsum Period. Increasing plant food use is indicated by numerous ground stone milling tools. The subsistence pattern included generalized hunting activities (large, medium, and small mammals and desert tortoise) and seed processing. Mesquite, an important resource throughout the Late Holocene, was established in high water table areas in the Antelope Valley by about 2,300 BC (early Gypsum Period). During the early part of the Gypsum Period settlement was likely characterized by residential mobility (foragers). Groups may have established residential bases in the foothills and rift zone, the mountains, and on the desert floor, and moved among them in a seasonal round. The CA-KER-303 site complex (near the mouth of Cottonwood Creek along the northwestern desert margin below the Tehachapi Mountains) and other sites (in and near the rift zone along the southern edge of the Antelope Valley) which have been characterized as sedentary major residential bases in later periods (villages in the Mission Period), were first occupied during the late Gypsum Period. These developments suggest an increase in population and occupation of the area by collectors (logistical Archaeological Research Design for the Antelope Valley Study Area 162 07A3822 Task Order 17 mobility) who established permanently occupied major residential bases along the desert margin in late Gypsum Period times. The occupants of these major residential bases probably sent task groups to obtain resources in the mountains and on the valley floor where they established temporary camps. The establishment of this collector pattern during late Gypsum times may coincide with the arrival of Takic-speaking populations in the Antelope Valley (see the Population Movements section). Sutton (2017) suggests that, during the Gypsum Period, the Mojave Desert valley floor was a “common pool resource zone,” i.e., resources on the valley floor were exploited by groups with residential bases located in the surrounding foothills (south and northwest of the Antelope Valley floor). Three archaeological sites (CA-LAN-1777, -1780, and -3873) from this time period and located on the valley floor appear to represent temporary camps associated with principal settlements located elsewhere. Data recovery excavations at the sites uncovered fire-affected rock features that were interpreted as roasting pits. Charcoal from Joshua trees were found in the features indicating use of Joshua tree wood for fuel. However, macrobotanical and pollen studies did not indicate what foods were cooked in the features. Protein residue analysis of the numerous ground stone tools recovered from the features failed to produce any results. Only a few small mammal bones were recovered and some of these may have been non-cultural (burrow deaths) (Kremkau et al. 2013). Rose Spring Period (circa AD 225 to 1100) There were major changes in cultural systems at the beginning of the Rose Springs Period. These include changes in artifact assemblages, a major population increase, and the appearance of welldeveloped middens (Sutton 2016). The bow and arrow were introduced in the Antelope Valley at the beginning of the Rose Spring Period circa AD 225. Arrow points include Rose Spring and Eastgate points, as well as Cottonwood Triangular points after A.D. 900. Other artifacts include stone knives and drills, bone awls, and ground stone tools. Manufacture of chlorite schist beads and steatite artifacts was being carried out in the southern Antelope Valley by this time and Olivella shell beads were traded in from the coast. Based on the presence of large residential bases around the western and southern peripheries of the Antelope Valley during the Rose Spring Period, a collector pattern (with major residential bases and temporary camps used by task groups) was likely present during this period. This pattern may have been established by the end of the Gypsum Period, The Medieval Climatic Anomaly (MCA) (AD 650 to 1250) with warmer drier conditions, including short periods of drought, began in the later Rose Spring Period and extended into the early Late Prehistoric Period. As a result of increasing aridity during the MCA, it is likely that the number of jackrabbits on the valley floor declined and juniper retreated to somewhat higher elevations in the northwestern Mojave Desert (Gardner 2007). There is a marked decrease in the number of lagomorph bones found in early Late Prehistoric sites compared to Rose Spring sites according to Gardner (2007). There is also a decrease in plant food use as indicated by a decrease in the number of ground stone tools in Late Prehistoric sites compared to Rose Spring sites. Ground stone tool use was also more intensive in the Rose Spring Period compared to the Late Prehistoric Period. Ground Archaeological Research Design for the Antelope Valley Study Area 163 07A3822 Task Order 17 stone tools were fragmented and burned, indicating re-use, in Rose Spring sites, but were whole and not burned in Late Prehistoric sites (Gardner 2007:242). During the MCA there was a reduction in both the size and number of residential sites. Late Prehistoric Period (AD 1100 to AD 1769) The archaeological material from the Late Prehistoric Period resulted from the activities of the ancestors of the ethnographic groups around the edges of the Antelope Valley region including the Kitanemuk, Tataviam, Serrano, and Kawaiisu. The use of the bow and arrow (with Desert SideNotched and Cottonwood Triangular arrow points) continued during the Late Prehistoric Period, along with most of the rest of the Rose Spring artifact assemblage. Intensive acorn use is indicated by the presence of numerous bedrock mortars, which were also used to process other plant foods, including pinyon nuts, chia, mesquite, buckwheat, and juniper berries. Small animals were also pulverized in bedrock mortars. The Little Ice Age (LIA) (AD 1350 to 1600), a cooler wetter period, occurred during the Late Prehistoric Period. The LIA likely had little effect on settlement and subsistence, other than to make plant food resources slightly more productive as a result of the increase in rainfall. Late Prehistoric archaeological sites that are major residential bases, and which are described as villages in the subsequent Mission Period, are located on the northwestern margin and the southern margin (rift zone) of the Antelope Valley. Major residential bases on the margins of the Antelope Valley include CA-KER-303 (Cottonwood Creek Site), CA-LAN-488 (Skelton Ranch Site), CA-LAN-82 (Barrel Springs), CA-LAN-192 (Lovejoy Springs), and the Totem Pole Ranch Site (Sutton 2016) (see the Previous Investigations section). CA-KER-303, CA-LAN-192, and CA-LAN-82 are known to have been occupied as early as the Gypsum Period. Fairmont Butte sites (including CA-LAN-298) also feature habitation sites with extensive, deep midden associated with the Fairmont Butte rhyolite quarry complex. Most of these large major residential bases probably became villages by Late Prehistoric times, if not before. Villages have “extensive and deep middens, considerable material culture, exotic materials, cemeteries, and architecture, and are thought to represent more or less permanent occupation locales” (Sutton 2016:269). The large major residential bases or villages were “persistent places” (continuously occupied places over many generations) based on cultural tradition, as well as the continuing availability of water and of plant and animal resources. The logistical mobility pattern established in previous periods continued and may have become more complex in the Late Prehistoric Period. Mission Period (AD 1769 to AD 1835) Mission records and other ethnohistorical resources indicate the presence of Desert Serrano and Tataviam villages located in or near the rift zone along the south side of the Antelope Valley during the Mission Period. Each independent Desert Serrano settlement was led by a clan chief and each exogamous patrilineal clan controlled the resources within a defined territory (Earle 2004, 2015) (see the Ethnohistory section). Thus, each village in the rift zone would have been near the center of a long narrow rectangular territory that extended from mountain uplands to the south across the rift Archaeological Research Design for the Antelope Valley Study Area 164 07A3822 Task Order 17 zone and out onto the floor of the Antelope Valley. Temporary camps would have been occupied while obtaining resources in the mountains (including acorns, pinyon pine nuts, and juniper berries) and on the Valley floor (including mesquite, Joshua trees, pronghorns, and jackrabbits). Although Sutton (2017) postulates that the Mojave Desert valley floor was also a “common pool resource zone” in the Rose Spring and Late Prehistoric Periods, this is not likely in these time periods, given the territoriality of Serrano groups at Spanish contact. Each Serrano clan probably claimed a strip of land that extended onto the valley floor, although the northern extent of these territories is unknown. This territoriality may have been established as early as the Rose Spring Period. Resources from the territories of other clans were obtained through marriage ties. Clans that intermarried would develop long-term relationships of material, ritual, and political reciprocity. Ritual reciprocity included holding ritual fiestas during which resources were exchanged. A clan would also host other clans with which it was intermarried in foraging and hunting activities within their own clan territory. The clans had bounded and defended territories and would give permission to members of allied clans to access resources within their own territory (see the Conveyance and Exchange section). Research Questions and Data Needs As the discussion in this chapter demonstrates, there have been few studies of hunter-gatherer settlement systems for the Antelope Valley, and reconstruction of settlement organization is based on ethnographic analogies and speculation. It is critical that future investigations in this region employ appropriate archaeological methods and theories for reconstructing the settlement systems in the valley through time. The following research questions and data requirements provide some guidance for such future investigations. Questions 1) What is the nature of hunter-gatherer settlement systems during the Clovis, Lake Mojave, and Pinto Periods in the Antelope Valley? Are residential bases dating to these periods situated in variable ecological zones or in a narrow range of environments? Is there evidence for human abandonment of the valley during the latter part (last 1,000 to 500 years) of the Pinto Period? Chronological sequences for the Mojave Desert, and specifically for the Antelope Valley, characterize early settlement systems in the region as being associated with residentially mobile hunter-gatherer populations. Population densities were likely low during the Clovis Period, and it is speculated that the sparse settlements of this time may have been concentrated around pluvial lakes, with big game hunting as the principal subsistence strategy. With increasing aridity during the Lake Mojave and Pinto Periods, subsistence strategies are suggested to have included exploitation of smaller game as well as plant foods from pluvial lake environments as well as upland areas. This suggests that settlements may also have been established at higher elevations in the valley. Finally, some scholars Archaeological Research Design for the Antelope Valley Study Area 165 07A3822 Task Order 17 have posited that the Antelope Valley was completely abandoned during the last 1,000 to 500 years of the Pinto Period as a result of the increase in aridity in the region. However, there are sparse archaeological data to support (or refute) these hypotheses as there are few sites identified for these periods. Identifying and investigating a large sample of sites dating to the early occupation periods of the valley is essential to defining the nature of early settlement systems. 2) Do settlement strategies in the Gypsum Period reflect a transition from a forager strategy to a collector strategy with the establishment of major residential bases occupied year-round by the end of the period? Could both residentially- and logistically-mobile populations have occupied the Antelope Valley at the same time during the Gypsum Period? Did the collector strategy with major residential bases in the desert margin and temporary camps for resource collection in the mountains and desert floor zones continue and become more complex in the later Rose Spring and Late Prehistoric Periods, culminating in the settlement system seen in the Mission Period? Is there evidence of internally differentiated site structure in the major residential bases (with structure bases and floors indicating houses, cemeteries, bedrock mortars, and other activity areas) that would indicate use by collectors? The presence of substantial middens dating to the late Gypsum Period has led to speculation that populations may have been more sedentary than in previous periods, with this pattern continuing during later periods and into Mission times. However, the build-up of midden at a site could also be a result of repeated use of the location by a residentially mobile population, rather than occupation year-round by a sedentary group. Using diversity and density measures may be a better way to distinguish residential bases of foragers from those of collectors, as discussed below, There is also the possibility that populations could have adopted a mixed settlement strategy over time, depending on ecological conditions (as well as social and/or political variables). Kelly (1983:301) notes that because “environments change their resource composition from year to year as a result of climatic fluctuations, we may expect to find different mobility strategies being used from year to year by a given group of hunter-gatherers.” Kelly (1983:301) also notes that with “increasing environmental heterogeneity we expect to find increased diversity within a group’s mobility strategy, such that the seasonal use of a given region could be accomplished through one form of mobility, and the use of another region through a different form.” Thus, researchers should consider the possibility of differing settlement strategies over time, e.g., populations becoming less sedentary, as well as seasonal differences. Another hypothesis to consider is that not all populations in a given area would adopt the same settlement strategy. Again, Kelly (1992:50) notes that even “when sedentary settlement systems develop, they do not necessarily involve all of a region’s people. As some people reduce their residential mobility, others may continue to be residentially mobile, perhaps developing a mutualistic relationship with the sedentary villages.” Archaeological Research Design for the Antelope Valley Study Area 166 07A3822 Task Order 17 Data Needs To address the research questions pertaining to ancient settlement systems in the Antelope Valley, a large sample of sites must be compiled and studied. Data sets that need to be considered in settlement studies include chronology, location, site structure, food remains, and artifact assemblage. Chronology Critical to this effort is placement of archaeological sites under investigation within chronological sequences, which should be done via the use of reliable chronometric dating techniques coupled with relative dating methods using temporally diagnostic artifacts. Most studies in the Antelope Valley have relied on projectile point typologies to date sites. However, radiocarbon dating of organic materials (e.g., carbonized plant remains, bone, shell), as well as obsidian hydration measurements, is critical. Materials used for these analyses must be collected from undisturbed contexts and in association with cultural deposits, and multiple dates should be obtained for each context (e.g., feature) being studied. Location Information on the paleoenvironment and the locations of settlements over time vis-à-vis ecological zones will be important to understand possible changes in mobility strategies as a result of climate changes. It will be important to compile a sample of sites from different topographic regions in the valley, and from all time periods. Site Structure Defining site structures will be an important part of determining the kind of settlement strategy represented at archaeological habitation sites. Data needed include dimensions of site areas, presence or absence of discrete midden concentrations and associated features within sites, and dimensions of middens and their distance from neighboring midden clusters. Also important to identify is the presence or absence of secondary refuse deposits and storage areas. Site structure is usually analyzed in the horizontal dimension with the assumptioon that site features were used contemporaneously. However, this should be verified through study of the chronological sequence of the site. There may be different vertical components within the site and it is possible that some of the site features belong to different vertical site components. Food Remains Data on animal and plant taxa represented in archaeological assemblages is another critical aspect of settlement studies. As discussed earlier, residential bases associated with foragers should exhibit low species diversity in food remains, and these should be of high-ranking resources. Residential bases associated with collectors should contain a high species diversity in food remains and include both high- and low-ranked resources. Type and quantity of both animal and plant remains should be used to estimate species richness and evenness for sites under investigation. Richness refers to the number of different animal taxa represented in an assemblage, and evenness to the uniformity of Archaeological Research Design for the Antelope Valley Study Area 167 07A3822 Task Order 17 their abundance/distribution (Kintigh 1989). The Shannon-Weaver Index should then be used to calculate the values for richness (H’) and evenness (V’). For richness, the higher the H’ value is, the higher the relative species diversity of an assemblage. Evenness or V’ can range from 0 to 1; the closer to 1 a value is, the closer it is to representing an even distribution of animal taxa. Only relatively large samples should be chosen for such analyses. Artifact Assemblage Information on the types and quantities of artifacts recovered from habitation sites is another element required in the analysis of settlement systems. Because most of the social, economic, and political interactions within the group are expected to occur at the residential base, artifacts recovered from such sites should reflect these various activities and interactions. Artifacts and features should be classified by function in order to reconstruct activities (hunting, animal food processing, plant food processing, food preparation and cooking, shelter and sleeping, manufacturing or maintaining tools, storage, and other activities). Site types (village, residential base, temporary camp, location [including lithic scatters], and other site types) should be defined based on (but not limited to) the types, quantity and distribution of artifacts and features present. The spatial relationships of activity areas and features will help to assess differentiation of internal site structure. Glassow (2013:68) suggested there should be a dearth of artifacts used for processing nonlocal food items at residential bases of logistically-mobile groups since such food items would have been processed at temporary camps. However, this would only apply to front-loaded resources. Backloaded resources would have been taken back to the residential base for processing (see the Subsistence section). In addition, it may be difficult to distinguish artifacts used for processing nonlocal food items from artifacts used to process locally obtainable items. Temporary camps should contain a narrow range of artifacts, most of which would be tools necessary to process resources to be transported to the residential base. It may be possible to define site type using various statistical measures, including diversity measures. In the Newport Coast Archaeological Project major residential bases, minor residential bases (frequently used temporary camps), and specialized activity loci (locations) used by collectors (Late Prehistoric Period) were differentiated from residential bases used by foragers (Milling Stone Period or Encinitas Tradition) using multivariate analysis (correspondence analysis and canonical discriminant analysis) of the distribution of the proportions of functional artifact types (Mason and Peterson 1994; Koerper, Mason, and Peterson 2002). Density measures were also used to distinguish between residential bases used by foragers and collectors. It was found that residential bases of collectors had at least 3.5 tools per cubic meter while residential bases of foragers had a lower density of tools (based on excavated material that was water-screened through 1/8-inch mesh). Densities of debitage and animal bone were also significantly different (Mason and Peterson 1994). In order to adequately carry out statistical analyses and compare densities among sites, the excavation methods must be comparable (same unit sizes, excavation in 10-cm levels, and same Archaeological Research Design for the Antelope Valley Study Area 168 07A3822 Task Order 17 screen size). It is recommended that when excavating sites in the Antelope Valley all units should be 1 x 1 meter in size, arbitrary 10-cm levels should be used, and all excavated material should be passed through 1/8-inch mesh. It should be noted that results from water-screening versus dryscreening are not comparable. Archaeological Research Design for the Antelope Valley Study Area 169 07A3822 Task Order 17 Theme: Subsistence An integral component of interpreting the dynamic relationship between humans and the environment in the Antelope Valley is to discern the relationship between subsistence systems and foods. Use of plant and animal foods by ancient populations is delineated through the study of macrobotanical remains, microbotanical remains, and faunal remains. Paleoethnobotany and Plant Use In this section, the discussion identifies four themes of importance to understanding the role of plants in archaeological subsistence settlements systems in Western Mojave Desert, with specific reference to the Antelope Valley. The four themes include resource intensification, human behavioral ecology, prehistoric diet, and ethnohistoric documentation of plant use. Before examining the four thematic issues pertaining to plant use, a synthesis of the current theoretical and analytical methods in paleoethnobotany is presented. Paleoethnobotany is the study of cultural plant remains from archaeological contexts, and past human-plant interactions (Hastorf and Popper 1998; Pearsall 1989, 2000; Marston et al. 2015). Paleoethnobotany is distinct from paleobotany which is the study of plant fossils from geological contexts. Another term used synonymously for paleoethnobotany is archaeobotany. Paleoethnobotanical studies provide the theoretical bridge between the botanical remains in the archaeological record that reflect cultural practices as expressed through food consumption. When recovered from discrete cultural contexts archaeological botanical remains provide valuable signatures of ancient subsistence systems and consumption practices. In addition, they also provide insight into how people organized themselves within their built and natural environment. Paleoethnobotanical data include micro- and macrobotanical data. Macrobotanical remains are those botanical remains that can be seen through a light-magnifying scope and/or naked eye, and include complete, or fragments of, carbonized seeds, nuts, nutshell, corms, wood charcoal, leaves, stems, plant parts, and plant impressions. Macrobotanical remains are most often the direct remnants of plants consumed as food; although seed bearing plants used as fuel, fodder and building materials could also be part of the collection depending on the context. Microbotanical remains are visible only through a high-magnification microscope and include pollen, phytoliths, residue analysis (including lipid and protein), and starch grains. Pollen data provide information on vegetation; phytoliths are often associated with parts of plants that are closely associated with habitation, while lipid residues and starch grains provide insight into perishable foods not represented in the macrobotanical remains (Marston et al. 2015). Starch grain and lipid residue analysis includes collecting residue washes from artifacts recovered in-situ and from associated sediments. Archaeological Research Design for the Antelope Valley Study Area 170 07A3822 Task Order 17 Processual archaeology formed the theoretical foundation of paleoethnobotanical studies until the early 1990s (Hastorf and Popper 1988; and others). However, paleoethnobotanical data have been used in a variety of interpretive approaches including post-processual gender theory (Hastorf 1991; Atalay and Hastorf 2006; Morell-Hart 2015), human behavioral ecology (Gremillion 2015; Marston 2011; Wohlgemuth 2002, 2010, 2016), niche construction theory (Reddy 2017; Smith 2015), evolutionary approaches (Rindos 1984), and ethnoarchaeological applications (Hillman 1981; Reddy 2003). Sampling The aim of paleoethnobotanical sampling for archaeological interpretation is to help address questions related to spatial patterns and specialized activity areas and is particularly relevant when research issues are related to food procurement, preparation, consumption, and disposal. Therefore, the sampling methods should be tailored to the research questions being asked in an investigation. Guedes and Spengler (2015) identify five variables to consider when sampling for paleoethnobotanical remains: research questions of the study, number of samples that can be feasibly analyzed by project (i.e., budget), number of samples that can be stored for future investigation (curation costs), contexts that have archaeological significance, and number of samples that will provide data for intra-site and regional comparison. All paleoethnobotanists insist that intensive sampling and strong contextual information are necessary for a paleoethnobotanical study to be effective. A rigorous and manageable sampling strategy is essential to providing a thorough understanding of the variation and similarity in activities related to food procurement, consumption, and disposal at a site (or series of sites). The challenge is determining an adequate sample; and typically “adequate” sampling comprises sampling of sufficiently large numbers of contexts as opposed to large samples from a few contexts. As such, the sampling could be bulk sampling (samples from single contexts like features) (Lennstrom and Hastorf 1992), pinch or scatter sampling (small sized samples are collected from a large context and then combined into a bag) (Lennstrom and Hastorf 1992), or column sampling (samples from column of soil which bisects stratigraphic levels at a site) (Pearsal 2000). For example, if the investigation examines depositional history, contextual richness, and temporal occupation, the sampling should include bulk and column sampling and samples from both habitation and non-habitation contexts. If the investigation is focused on landscape reconstruction and changing vegetation as pertaining to what plant foods were available for exploitation by site occupants, pinch grab sampling would be more appropriate. All three types of sampling can be implemented at the same site and project. Sampling for microbotanical remains (pollen, phytoliths, and starches) is largely similar to those of macrobotanical remains with two exceptions. First, burnt contexts which are ideal for macrobotanical remains are not productive for pollen (Bryant and Holloway 1983). Second, open air sites are not good contexts to sample for pollen (due to poor preservation and disturbance). Pollen and phytolith sampling require control methods of collection, and all sample collection should be done by individuals who are familiar with the process. Similarly, sampling for starch (from soils and artifacts) is Archaeological Research Design for the Antelope Valley Study Area 171 07A3822 Task Order 17 a precise technique and collection should be done by an experienced individual. The specifics of sample collection techniques for pollen, phytoliths, and starches are provided by Guedes and Spengler (2015) and Pearsall (2015). Recovery Methods Recovery of paleoethnobotanical remains involves several techniques. This discussion is focused only on macrobotanical recovery, and the goal of the recovery is to isolate the carbonized plant remains from the sediment in an effective and efficient manner. The technical method used is dependent on the organic preservation at the site, number and size of the samples, and budgetary restraints. The methods include dry screening and wet screening (see Lawlor 1996; White and Shelton 2015; among others). Dry screening is done with sediments from very arid areas when there is a potential of carbonized remains being destroyed by contact with water. The technique involves screening the sample sediment through fine mesh screens into different size categories (geological sieves are often used; for example, 4.0, 2.0, 1.0 and 0.425 mm). The larger size categories can be sorted easily by picking out the carbonized remains from the rest of the sediment, but the smaller size categories will need to be sorted under a microscope. The advantage of this method is that there will be minimal loss of carbonized remains exploding or melting when put in water. The drawback is that the sorting is time-consuming. The wet screening method involves flotation of the cultural sediments to retrieve carbonized remains and there are two main flotation methods: bucket/hand and machine flotation. The bucket/hand method is the least expensive, and this involves using large buckets to submerge the sediment in water and agitate the mixture to release the carbonized remains from the sediment. The carbonized remains float to the top and are captured in a mesh skimmer or decanted/poured out into a mesh catcher. The machine flotation includes constructing a machine that brings water to the flotation system and sprays the water upwards on the sediment which is poured in and through the water under pressure and agitation. The carbonized materials are then released and caught. White and Shelton (2015) have detailed discussions of the different methods with illustrations. Regardless of which method is chosen, it is important to do a recovery rate test (done typically using poppy seeds) so that the investigator has a control on how well the recovery is working. Analysis Regardless of which recovery method is being used, the recovery process results in a light and a heavy fraction from each sample. All light and heavy fractions are sorted using a similar method. Typical steps in the sorting include sieving each light and heavy fraction through nested geological sieves (for example 4.0, 2.0, 1.0 and 0.425 mm). Such presorting is an effective way to remove modern rootlets and leaves and to isolate small flakes, bones, and shell. If the sample size is large (>10 liters), a subsample representing 10 liters of sediment should be taken immediately from each sieve size. Each fraction is then sorted under a binocular microscope (5×–15×). Charcoal should be collected from as many sieves as possible. Carbonized seeds should be removed from all sieves and Archaeological Research Design for the Antelope Valley Study Area 172 07A3822 Task Order 17 stored in vials. When all sorting is completed, the charcoal should be weighed, and the sorted light fractions made ready for curation and/or repatriation. Identification of the carbonized seeds should be through comparison with comparative materials and identification manuals (for example Martin and Barkley 1973; Musil 1963). Unless the site(s) has exceptional preservation, the macrobotanical analysis should only include carbonized seeds. In general, when uncarbonized (uncharred) plant parts are recovered from archaeological sites, it is important to determine whether they were associated with cultural activities in the past or whether they entered the site through natural processes in more recent times. Paleoethnobotanists typically consider the carbonization of plant seeds to be the most reliable and conservative indication of antiquity. In other words, uncharred plant materials at archaeological sites are generally considered unrelated to prehistoric human use of plants, because they would not be expected to have been preserved in typical open-air sites (Minnis 1978) (Note that cave sites are an exception to this). Charred specimens, on the other hand, are often assumed to be related to intentional or unintentional prehistoric human use of fire (usually food preparation). Of course, there are situations when such a dichotomy is not possible; for example, consider ChenopodiumAmaranthus–type seeds. It takes a highly trained eye to discern charring on these naturally black seeds, especially when they are not swollen or broken open for an interior view. Care should be taken so that only carbonized seeds are included in the analysis and interpretation. Post-depositional disturbance should be measured in the analysis by adopting a qualitativecategorical method. It is crucial to note post-depositional disturbance in paleoethnobotanical studies so that association of low densities of particular taxa can be explained effectively as cultural or biological. For example, although only carbonized seeds should be recovered from the light fractions, the presence of uncarbonized seeds should be noted, along with other organic materials such as rodent fecal matter, insect parts, worms, land snails, etc. These data will be integral to determining post-depositional disturbance in each sample, which will be critical for interpretation. Data analysis of macrobotanical data can be done through different tools. For example, patterns in the macrobotanical data can be discerned through the use of density, percentage, and taxonomic richness (Marston et al. 2015). At the basic level, a presence/absence or ubiquity approach can used to provide summary information for comparing how common each taxon was in each sample/context/period. Analysis should measure the intensity with which a plant resource was used, not just the mere use of the specific resource(s), because it is important in understanding competitive replacement of adaptive strategies. In this sense, densities, percentages, and taxonomic richness indices are instrumental for such measurement. Charcoal densities are used to define varying preservation contexts at and between the sites and also the intensity of activities involving plants and fire. Seed densities define the intensity of plant usage. Percentages of different taxa reflect the relative abundance of a specific taxon in a collection. Ubiquity or presence analysis (each taxon is scored as present or absent in a sample and then given a frequency measure) provides information on the relative importance of taxa. Ubiquity measures the number of accidents (incidents Archaeological Research Design for the Antelope Valley Study Area 173 07A3822 Task Order 17 when there was accidental spillage or disposal during processing, preparation and consumption) associated with the taxon and, therefore, the degree of usage. Taxonomic richness is a qualitative measure of plant-taxa diversity (high diversity suggests a generalized assemblage; low diversity is indicative of a specialized assemblage; both are used to define plant-exploitation strategies). Sources of Seeds When examining the roles of plants in prehistoric subsistence economies, it is very important to define which plants represented in the macrobotanical collection are associated with the occupation of the site and which are non-cultural, intrusive contaminants. As such, the original sources of the seeds are critical to define and what parts of plants were used is important, because their representation in the archaeological record can be biased, depending on whether they survive or not. Leafy parts of the plant, roots and tubers, and very dry or very oily parts all have a low chance of surviving carbonization. As such, there is an inherent bias in the archaeological record toward seedbearing parts of the plants. Seeds enter the archaeological deposits through a variety of pathways (Bush 2004; Keepax 1977; Miksicek 1987; Miller and Smart 1984; Minnis 1978; Reddy 2003). A carbonized-seed collection from a single site could represent plants used as food and medicine, as well as for fuel and building. Seeds could become part of the site midden from wildfires and natural seed rain during site occupation that became carbonized in hearths. Logically, seeds that were used as food would be less likely to be recovered, because the majority of them would have been consumed. Therefore, what is recovered from the archaeological sediments are those seeds from accidental spills and intentional discards during food processing, preparation, and consumption, and perhaps in proximity to hearths and other contexts that involved plant foods and fire. Reddy (2003) has documented that intentional discards were typically undesired seeds, which may have been immature, worm infested, or otherwise unpalatable. Similarly, fruit pits and nutshell may also have been discarded into hearths as trash disposal. Summary Paleoethnobotanical studies have played a major role in archaeological investigations in general since the late 1980s in the United States and Europe. Before the late 1980s, most paleoethnobotanical studies focused on environmental reconstruction (pollen data) and providing plant lists for archaeological interpretations. This trend changed dramatically starting in the 1990s with scholars addressing a wider range of research issues in archaeological and also in paleoethnobotanical contexts. Some of the trends include greater insights into formation and depositional processes involving plant remains, sampling strategies, new and improved quantification methods and digital technologies, integration of plant data with other environmental data, and integrating paleoethnobotanical data into mainstream archaeological interpretations (Marston et al. 2015). Archaeological Research Design for the Antelope Valley Study Area 174 07A3822 Task Order 17 Paleoethnobotanical research in California has several recurring research themes: intensity of plant use over time, defining the nature of plant exploitation over time, the importance of acorns in the diet, and the use of annual grasses (Hammett and Lawlor 2004; Popper 2002; Reddy 1999, 2004, 2015, 2016; Wohlgemuth 1996, 2002, 2010, 2016). In general, there is a dearth of paleoethnobotanical studies in the Mojave Desert relative to the coast (Reddy 2016; Reddy and Wohlgemuth 2016). This is due to two main reasons: scholars working in the area have not recognized the importance and interpretive potential of paleoethnobotanical data, especially macrobotanical data and, due to this inherent bias, there have been few studies that have collected and incorporated micro- and macrobotanical data. Furthermore, paleoethnobotanical data has been primarily used in paleoenvironmental reconstructions, and rarely in prehistoric subsistence reconstructions. Some exceptions are Klug and Popper (1994), Lawlor (1995), Reddy (1996, 2013), Sutton (1984), and Sutton, Robinson, and Gardner (2006). Resource Intensification Resource intensification is measured through the relative proportion of high-ranked versus lowranked taxa where there is an increase in the low-ranked resources (such as small seeds) compared to earlier time periods, resulting in a broadening of diet breadth. Resource intensification requires greater labor costs (measured in terms of time or energy/calories) associated with procurement (harvesting/gathering) or processing prior to consumption (leaching, milling, cooking) for lowranked plant resources. However, the application of increased labor to procure and process these high cost resources, results in higher yields/production per unit of land. Initially, plant intensification may result in a broadening of the diet breadth as more low-ranked resources are added to the diet; subsequent increased intensification of resources already being used results in even greater reliance on low-ranked taxa already being used. Basgall (1987) was one of the first scholars who discussed resource intensification in California (acorns). Macrobotanical data have been used to argue for resource intensification in central California (Wohlgemuth 1996; 2016) and coastal southern California (Mason and Peterson 2014; Reddy 2004, 2016), but no such interpretations have been made for the Western Mojave Desert plant use. Using return rate data (energy yield when consumed) from the Great Basin, Bettinger and Wohlgemuth (2006, 2011:125) have ranked commonly exploited plant resources in order from highest to lowest rank as follows: terrestrial roots, nuts and acorns, small seeds, and aquatic roots. However, acorns are a low-ranked resource when taking into account the processing time necessary prior to consumption (Codding, et al. 2012). Such work provides important baseline data to operationalize resource intensification theoretical expectations. Discerning the causal factors behind resource intensification have been widely discussed, and among the factors that have been considered are over-exploitation of high ranked resources and/or decreasing efficiency in their procurement over time due to greater search time or decreased encounter rates (Bettinger 2008; Broughton 2001; and others) or population growth and territorial circumscription (Beaton 1991). Archaeological Research Design for the Antelope Valley Study Area 175 07A3822 Task Order 17 In the context of resource intensification, histories of species-specific exploitation are of importance because they provide insight into broad changes in diet and the impacts of human exploitation. For example, plants of interest in Western Mojave Desert, Antelope Valley and the adjacent mountain slopes include acorns (Quercus spp.), bur-sage (Ambrosia dumosa), cactus, Joshua tree (Yucca brevifolia), juniper (Juniperus spp.), mesquite (Prosopis sp.), piñon (Pinus spp.), saltbush (Atriplex sp.), and yucca (Mojave yucca) (Yucca schidigera). The exploitation of these plant foods can be identified primarily through regional data. Intensity of plant use can be measured through ratios, while reliance on particular plants can be measured by frequencies and ubiquity. There is also an upland-lowland dichotomy on where some of the plants would have been available that also needs to be considered. Junipers grow on lower slopes, mesquite needs a high water table on the valley floor, oaks are on slopes and in canyons, piñon would be at higher elevations in the mountains, and small seeds would be on the valley floor. Knowing how far certain resources are located from a particular settlement allows for consideration of transportation costs in assessing the degree of resource intensification. Basgall (1987) argued that acorns were not intensively used in central California until the Middle Period because of the time and energy necessary to process them prior to consumption. The reason intensive acorn use in central California began relatively late in time (indicated by large scale mortarpestle use after 4000 to 1000 BP, depending on the geographic area) is the intensive labor required for processing acorns, which includes shelling, grinding, and leaching. Using acorns requires “a truly spectacular investment of female labor” (Bettinger 2015:110). Acorn use was a high-cost subsistence orientation that was not used until increased production at the expense of productivity was necessary due to increasing population size and density (Basgall 1987). While Basgall’s (1987) study of the timing of acorn use was based on the appearance of mortars and pestles, macrobotanical studies of charred seeds and nuts from archaeological sites in central California corroborate the timing of the beginning of acorn use. The results of the macrobotanical studies show that acorn use began in the Middle Period and continued through the Late Period (Wohlgemuth 1996). Intensification of piñon collection in the mountains should be considered, but whether piñon should be considered to be a low- or high-ranked resource may be related to when it is harvested: brown or green cone (Eerkens et al. 2004). Brown cone harvesting requires less energy because the procurement is done when the pine cones are open and the nuts can be easily knocked out, but overall productivity varies depending on competition with birds and rodents. In contrast, green cone harvesting requires more energy (involved caching and elaborate processing) and results in lower yields per unit of time relatively. However, there is little competition with rodents and birds. Some scholars have questioned the remarkable ranking difference between brown and green cone harvesting, because brown cones can be carried great distances and stored, while green cones cannot be stored, nor can they be transported long distances (Hildebrandt and Ruby 2006). Therefore, distribution of resources, proximity to residential camps and whether the plants grow in dense patches or not, all play important roles in determining whether resources should be ranked as low or high. Using data from Owens Valley in the Great Basin, Bettinger (1976) has argued that piñon was largely ignored as an important food source until sometime between AD 600 and AD 1000. The Archaeological Research Design for the Antelope Valley Study Area 176 07A3822 Task Order 17 change in exploitation was because other resources decreased and population increased. It would be interesting to explore whether a similar pattern of exploitation also occurred in the mountains around the Antelope Valley. While it is likely that there was intensification of foothill and mountain resources such as acorns and piñon, intensification of valley floor resources, such as mesquite, has not been investigated. Another type of resource intensification is cultivation and/or agriculture; indeed it can be considered the final stage in the trajectory of increasing effort in plant exploitation. Byrd et al. (2011) state that agriculture was practiced along the Colorado River, but there is no evidence of cultivation or agriculture by Native Americans in the Antelope Valley. In summary, research issues in paleoethnobotanical investigations of resource intensification include defining regional variation in plant use, localized histories of plant food use and exploitation, timing of species-specific intensification, the role of scheduling conflicts in resource choice. Human Behavioral Ecology Human behavioral ecology (HBE) in an archaeological context consists of interactions between daily subsistence activities and environmental variability. Success of decisions dynamically alters future foraging. HBE can be described as a “field that studies behavioral adaptation without making the claim that all behavior is adaptive” (Gremillion 2015:340). HBE uses models to connect theory and data. Aspects of optimal foraging theory such as central place, diet breadth, risk minimization, and prey choice, have particular value to interpreting plant use using HBE. For example, the central place foraging model is useful in examining logistical and non-logistical foraging factors for plant resources. Diet breadth was discussed earlier, as an aspect of resource intensification, and its HBE application lies in that a food is added to the diet only if the net return is greater than the procurement and processing costs. Central place foraging can be applied to plant resource exploitation in terms of logistics of foraging for specific plants. The travel and transport costs will place constraints on how much food is collected and therefore, determine the food choice. Field processing versus transporting to a residential base also plays a role in the food choice. Research in the Great Basin on transportation, field processing, and travel costs has demonstrated that if the travel distances are great, the resources procured should have a higher energy yield (Barlow and Metcalf 1996; Jones and Madsen 1989; Metcalf and Barlow 1992; Rhode 1990). Gremillion (2015:351) proposes that field processing is, in particular, of importance to paleoethnobotany because field processing takes time away from gathering, but also results in a cleaner product being taken back to camp. The question is, how much time should be spent to bring back a clean basket of plant foods? Metcalf and Barlow (1992) argue that how much time is spent field processing and cleaning the plant foods at the collection area is dependent on travel time/distance from the residential camp. Search costs are another aspect of HBE that have big implications for choice of food. Some plant foods that produce nuts or pods, such as acorns, piñon, Archaeological Research Design for the Antelope Valley Study Area 177 07A3822 Task Order 17 and mesquite, have lower search costs compared to small seeds. Handling costs also vary by plant; for example, handling costs of yucca are higher than acorns and piñon. Recent research on foraging range and patch choice has employed GIS analysis of least-cost path distances between residential camps, resource patches and storage features (cache areas). For example, Morgan (2008) has examined Late Prehistoric Mono foraging radii in the southern Sierra Nevada using least-cost analysis techniques and his results reveal a different distance limit for caching versus foraging. Such data are useful to model complex social and economic factors involved in subsistence-related behavior. Forager sensitivity to risk is another aspect of HBE that has been explored in California prehistory, but with particular focus on animal exploitation. The basic tenet is that the goal of foraging is to maximize its net energy acquisition; but risk minimizing (avoiding starvation or food shortage) also plays an important role (Winterhalder 1986). Winterhalder (1986) and Winterhalder and Goland (1997) proposed a Z-score model for food choice which differs from the diet breadth model in that it is stochastic and assumes that decisions have variable outcomes and are not pre-determined. Gremillion (2015:352) explains this as “A bird in the hand may be worth two in the bush – but not if one bird is not enough to keep you alive.” The use of food in general to signal group identity has been well discussed (for example Rozin and Fallon 1981). Using macrobotanical data, preferences for certain plant foods have been discussed recently for coastal and central California by Reddy and Wohlgemuth (2016). Diet choice is a complex theme to explore, and specifically for plant resource exploitation, because HBE methodologies have not been as well developed for plants (relative to animals) (Gremillion 2015). Tushingham and Bettinger (2013) have proposed that whether a resource is front-loaded or backloaded determines when it is exploited. Front-loaded plant resources, such as seeds, roots/corms, and yucca, require more energy and effort in procurement and processing before they can be stored; however, they do not take a lot of time to prepare afterwards. In contrast, back-loaded plant resources, such as acorns and piñon nuts, require less energy to procure and no processing is needed before storage. However, greater processing costs and efforts are involved to process the stored nuts before consumption. In applying this model, a forager has to decide which type of resource will be more efficient in terms of the subsistence needs – immediate food need, processing costs and labor, and need for storage. Tushingham and Bettinger (2013) argue that if ample frontloaded resources are available, early foragers would have chosen them; and back-loaded resources, which could be stored, became important as groups became more sedentary. The Prey Choice Model (PCM) seeks to explain whether an individual should pursue a resource when encountered or ignore it and seek more easily attained items (Codding et al. 2012:120-121). It is based on ranking resources by post-encounter profitability, defined as expected energetic return, divided by expected handling expenditures. Handling includes pursuit (all activities involved in acquiring the resource) and processing (all activities to render the resource edible such as butchering Archaeological Research Design for the Antelope Valley Study Area 178 07A3822 Task Order 17 and cooking). High-ranking resources, such as deer, would ideally be pursued whenever encountered and low-ranked resources (such as rabbits) added only when the abundance of high-ranked items declines. Codding et al. (2012:124) suggest that for most terrestrial animals, prey body size is analogous to energy and that prey mobility is analogous to pursuit cost. Based on this argument, large, slow animals would be ranked higher than small, fast animals. Ideal Free Distribution (IFD) assumes that people will choose to live in areas that will meet their subsistence needs (Codding et al. 2012:116-117). It predicts that the highest-ranking habitats should be inhabited first and that lower-ranking habitats should only be occupied when population density inhibits subsistence success. Thus, higher-ranking habitats should have a higher population density. In summary, outstanding research issues in paleoethnobotanical investigations of human behavioral ecology include central place/foraging place as it pertains to what is harvested and brought back to the camp versus resources processed at procurement locations; defining the diet breadth over time; how risk was minimized (presence of storage; back and front-loaded resources); and patch choice (which plant resources were specifically targeted). Role of Plants in the Prehistoric Diet In defining prehistoric plant use by California Native Americans, scholars have either emphasized similarities across California by focusing on primary plant resources or emphasized the wide array of resources that were exploited (Anderson 2005; Baumhoff 1963; Heizer and Elsasser 1980; Kroeber 1925; Powers 1877; Bean and Lawton 1976; Jacknis 2004; Lightfoot and Parrish 2009). Reddy (2016) expressed concern that much of the reconstructions of plant use are drawn from the ethnographic and ethnohistoric record (Ball 1962; Clarke 1977; Ebeling 1986; Merrill 1918; Moerman 2010; Strike 1994; Timbrook 2007), rather than being built from direct paleoethnobotanical evidence. To accurately and effectively model prehistoric plant use and interpret diachronic changes in subsistence strategies in the Mojave Desert, it is imperative to obtain paleoethnobotanical data. The nature and characteristics of plant use should be investigated by obtaining information about range of taxa exploited, processing methods, storage, and seasonality, among others. Information about the range of taxa exploited provides an insight into whether there is resource intensification (as discussed earlier) and changes or continuity in patch choices. Contextual analysis can provide insight into processing methods: • Were plants processed at the residential base? • Were they processed at the gathering site and brought to the residential base as a cleaned product (for example see Reddy 2003, 2017)? • Which plant foods were stored (Eerkens 2003a)? Using data from the Owens Valley, Eerkens (2003) examined how storage of plant foods was integral in the development of sedentism during the early Haiwee period (ca 1350-650 BP). Storage of plant Archaeological Research Design for the Antelope Valley Study Area 179 07A3822 Task Order 17 foods is an important marker of intensification of plant exploitation. Some of the plant foods in Antelope Valley that can be stored include small seeds, and piñon and acorn nuts. Available Food Plants in and Around the Antelope Valley The dominant prehistoric plants of the Western Mojave Desert that could have been used as food resources included acorns (Quercus spp.), bur-sage (Ambrosia dumosa), cactus, juniper (Juniperus spp.), Joshua tree (Yucca brevifolia), mesquite (Prosopis sp.), Pine (Pinus spp.), saltbush (Atriplex sp.), and yucca (Spanish bayonet/common yucca [Hesperoyucca whipplei spp. – formerly Yucca whipplei]). Some of these occur on the foothill and mountain slopes around Antelope Valley, while others occur on the valley floor. In addition, screwbean (Prosopis pubescens), mesquite (Prosopis glandulosa) and Indian ricegrass (Stipa hymenoides) were also present on the valley floor and were likely exploited. Fowler (1986) described how different technologies are needed for the collection and processing of these plants and, based on these differences, he has defined different plant complexes based on tools needs for procurement and processing. Three plant groups are relevant to the Antelope Valley study area: yucca; piñon; and mesquite and screwbean. In addition, supplemental plant foods such as small seeds and berries were also important. Yucca. The yucca family of plants includes Joshua tree (Yucca brevifolia), Mojave yucca (Yucca schidigera), banana yucca Yucca baccata), and beargrass (Nolina spp.). Traditionally, yucca fruit and seeds of Joshua tree and Mojave yucca were consumed as food after being roasted and parboiled (Ball 1962; Bean and Saubel 1972; Clarke 1977; Ebeling 1986; Knack 1980; Moerman 2010; Strike 1994). Joshua tree (Yucca brevifolia) is a high desert plant which grows on gentle slopes and has a wide distribution range. It is found in the foothills and on the valley floor of the Study Area. It is found in the Joshua tree woodland community in the foothills and foothill canyons at elevations of 3,000 feet or below (Earle et al. 1995). In addition to Joshua tree, this vegetation community includes juniper and a range of small seeded plants (chia, buckwheat, boxthorns, and saltbush). Joshua tree is also found in the lower elevation ranges of the sagebrush scrub (3,500 and 7,000 feet AMSL), desert chaparral (3,000 and 6,000 feet AMSL) and pinyon-juniper (3,000-6,500 feet AMSL) communities. Joshua tree is also found on the Antelope Valley floor (below 3,000 feet AMSL), but in lower frequencies (Sutton 1988b). In the study area, yucca became a part of the vegetation from about 8,300 years ago and continued to be a part of the vegetation through time. Louderback et al. (2013) provide a synthesis of yucca use in the Mojave Desert and macrobotanical remains from sites in the eastern Mojave Desert that indicate spring gathering and processing. In the central Mojave Desert, agave is also part of the yucca complex; however, agave does not occur in the Antelope Valley. According to the ethnographic and ethnohistoric documentation from the Kawaiisu, Kitanemuk, and Serrano, edible parts of Joshua tree (Yucca brevifolia) – stalks, basal hearts, buds, fruits and seeds were collected as food in the spring (Harrington 1986:III:98; Walker 1931:15; Zigmond 1981:69). The Chemehevi ate the fruit of Mojave Yucca (Yucca schidigera), and Earle et al. (1995) explain that Hesperoyucca whipplei (Spanish bayonet) was also harvested in the foothills in the spring. They report that “roasting ovens used to prepare the stocks are frequently encountered in the foothill Archaeological Research Design for the Antelope Valley Study Area 180 07A3822 Task Order 17 areas where sufficient quantities of fuel were available” (Earle 2015:25). Earle et al. (1995) reported that the roasting of yucca buds (and also piñon cones) would have to be done where there was ample fuelwood available; and they reference King et al. (1974:15) who states that the Tataviam roasted the yucca buds where the yucca was in close proximity with juniper plants so that juniper wood could be used as fuel. Yucca whipplei was often the first food available in the Antelope Valley foothills in the spring (Earle et al. 1995). The basal hearts are available early in spring, while the blossom stalks could be harvested through early summer. The stalks, basal hearts, buds, and fruits were boiled or roasted before consumption. Kitanemuk and the Cahuilla roasted the whole stalk before eating them; the Cahuilla ate the flowers fresh, boiled or dried (Timbrook 2007: 229). Bean and Saubel (1972) report that mature flowers were boiled while immature flowers were eaten raw. The roasting was done in ovens that could be as large as eight feet across and four feet deep and sometimes were rock-lined (Bean and Saubel 1972; Timbrook 2007). The yucca parts to be cooked would be placed in the pit and covered with sand (Bean and Saubel 1972). The cooking could take as long as two days. The roasting ovens used to prepare the stocks are frequently encountered in the foothill areas where sufficient quantities of fuel were available (Earle et al 1995). Use of agave in archaeological contexts is documented by ring middens which are “elevated rings of stone and soil, between five and twenty meters in diameter, surrounding a ground-level central area.” (Schneider et al. 1996:29). Piñon Nuts. Piñon would be available on the mountain slopes around the Antelope Valley, and particularly on the San Gabriel Mountain slopes where oak-piñon-juniper woodland is present. The elevation range for piñon ranges from 3,000 to 6,500 feet AMSL (Earle et al. 1995:1-11). Pine nuts would have been the focus of intensive gathering and collecting during years of abundance (typically in 3- to 7-year cycles, according to Lanner [1981]). Pine nuts were obtained from the single-leafed pinyon pine (Pinus monophylla) growing on the foothills and lower mountain elevations, in late summer and early fall. After harvest they are stored immediately or first parched and then stored followed by considerable processing before consumption (Bean 1972; Knack 1981). If green cone harvesting occurred (as discussed earlier), the harvesting would occur in mid-summer before the cones are fully ripened. The piñon cones and nuts were stored at the residential base or village within rock rings (Bean Saubel 1972), baskets, or granaries. Pine nut gathering was often a community event, and Earle et al. (1995) reported that on occasion different clans were invited into another clan’s territory to gather piñon cones and nuts. Referring to Harrington’s notes (Harrington 1986:Reel 101:Fr. 15,326), Earle et al. (1995) noted Serrano clan leaders invited other Serrano and Cahuilla clans to pine nut gathering forays. Depending on the distance between the piñon groves and the villages, on occasion the entire village would move to the piñon grove(s) area to camp during the gathering season. The pine cones were harvested by pulling them down from trees with crooked poles, and then the cones were processed in the temporary camps. The processing involved heating the cones on fire to open them up to remove the partially parched nut. Nuts were then removed from the cone. These nuts were either transported back to permanent settlements for storage without being hulled or were cached locally. Before Archaeological Research Design for the Antelope Valley Study Area 181 07A3822 Task Order 17 consumption, the nuts were hulled (nut shells removed) by rolling a handstone over them and then winnowing them in a basket before they were eaten or made into a mush by cooking the nuts (Barrows 1967; Bean and Saubel 1972; Timbrook 2007). Green piñon cone processing is front-loaded; while brown cones can be front- or back-loaded. Acorns. The role of acorns in the pre-contact diet of the Antelope Valley inhabitants is unclear. Earle et al. (1995) argue that the lack of archaeological focus on acorns as an important food source in this region is a byproduct of using Great Basin models of subsistence which emphasizes small seeds. Alternatively, it is important to incorporate the role of return rates on acorns compared to pine nuts which were readily available. Oaks such as interior live oak (Quercus wislizenii) and canyon live oak (Quercus chrysolepis) are found up to 7,000 feet on the northern side of the San Gabriel Mountains. For example, the Liebre Mountain Range ridge on the southwestern side of the Antelope Valley was an important acorn gathering area during the ethnohistoric period, as documented by Harrington (Harrington 1986:98:98). Clans with abundant acorns in their territory could invite other clans with which they had good relations to gather acorns in their territory. Acorn gathering in the oak groves was done in the fall. Minimal processing was done at the gathering location, except drying. The nuts were transported to the villages and stored for future use. Intensive labor investment was necessary in order to make acorns ready for consumption. The processing involved pulverizing with a mortar and pestle (bedrock mortars were often used), leaching with water (therefore limiting where the processing could have occurred), and cooking the resulting acorn-meal. Acorns are back-loaded resources. Mesquite and Screwbean. Mesquite (Prosopis glandulosa) and screwbean (Prosopis pubescens) grow in the Mojave Desert where the water table is high. Antelope Valley did have a high water table until historical times, and mesquite is found on the Antelope Valley floors and playas (below 3,000 feet AMSL) (Earle 2015; Sutton 1988b). Sawyer (1944) described mesquite “forests” at Edwards AFB which occur in areas of higher subsurface water typically in the vicinity of springs and/or lakes, including Buckhorn Springs. Bean and Saubel (1972:108-109) summarized the seasonal use of the three main mesquite foods among the Cahuilla: blossoms in the spring, green pods in early summer, and mature dried pods in the early fall. The blossoms were picked, roasted, and made into balls for consumption. They were also used to make tea. The entire family was involved in the harvest of mesquite pods which could span several weeks. Similar to green cone piñon harvesting, the mesquite and screwbean pods could be harvested before they are completely ripened to minimize competition with birds and rodents. The green pods were dried and then prepared (similar to the dried pods); or they were prepared immediately by pounding with water to produce a pulpy drink. The mature pods could be stored whole or processed as flour and cakes (Bean and Saubel 1972). The mesquite bean pods and beans were pounded and consumed fresh or formed into cakes and dried for use later (Barrows 1967; Bean and Saubel 1972; Earle et al. 1995). Sometimes the pods (before being pounded) and flour/cakes and Archaeological Research Design for the Antelope Valley Study Area 182 07A3822 Task Order 17 nuts were stored in baskets or granaries (Bean and Saubel 1972). Dried mesquite is a back-loaded resource, while the blossoms and green pods are front-loaded resources. Juniper Berries. Several plant foods served as secondary but important food sources for the Antelope Valley prehistoric populations. These include juniper berries, islay berries, and small seeds. Juniper berries were a consistent prehistoric food source throughout California; although their contribution to the Western Mojave prehistoric diet is debated. Based on their work among the Cahuilla, Bean and Saubel (1972:81-82) suggest that the berries were not a major food source but were eaten in large quantities when available in the summer months. In contrast, Zigmond (1981), using information collected by Harrington, argues that juniper berries were a staple. Harrington’s information is derived from San Gabriel Mission records from 1813 in which juniper berries along with acorns, yucca stalks, and pine nuts were listed as being staples for the Native Americans (Geiger and Meighan 1976:81). Earle et al. (1995) note that juniper is found on the lower foothills and upper valley floor from the southern Antelope Valley eastward to the Mojave River and beyond, and westward on the San Gabriel Mountains foothills. In particular, they refer to the area between Victorville and the Cajon Pass which was known for juniper berry gathering in the nineteenth century. As part of the pinyonjuniper woodland, juniper occurs at elevations between 3,000 and 6,500 feet AMSL, but it also occurs at lower elevations. Joshua tree-juniper woodland is intermixed with saltbush scrub in the desert margin (around 2,400 feet [731 m] and above) on the south side of the valley. Juniper woodland is extensive at higher altitudes in the canyons, foothills, and ridge slopes south of the Antelope Valley. Earle (2015) notes Joshua tree-juniper woodland was noted in the western part of the Antelope Valley floor, especially along today’s SR-138, by pioneer travelers. These woodlands were heavily impacted by twentieth-century agriculture. Isolated juniper trees are currently found on the Antelope Valley floor (below 3,000 feet AMSL) (Sutton 1988b). The study area could have had two types of juniper trees: the more common California juniper (Juniperus californica) and the closely related and rarer Utah juniper (Juniperus utahensis) (Earle et al. 1995). Juniper berries were collected for food and wood was collected for fuel. Earle et al. (1995) note that glaucophane schist metates are found in the juniper-dominated areas of the Antelope Valley foothills, and they may have been used to process juniper berries and small seeds. As such, the authors propose an association between the distribution of glaucophane schist metates in juniper zone foothill camps and the processing of juniper berries. The berries are available in the summer months, and they can be consumed in several ways: eaten raw, dried and ground into flour and made into bread, or boiled and consumed (Timbrook 2007; Zigmond 1981:35). Juniper berries are front-loaded resources. Islay Berries. Islay berry or holly-leafed cherry (Prunus ilicifolia) was another significant nut food resource on the southern margin of the Antelope Valley and the San Gabriel Mountains foothills. The Islay nut, tasting much like an almond, was a favorite food item (Harrington 1986:III:98:112,186191,363). The berries were ready for harvest in late summer months. It is not clear whether the berries were consumed raw. Bean and Saubel (1972:120) report that the berries may have been too astringent for immediate consumption, and they had to be leached well before consumption. The processing involved several steps, including an initial step of drying the berries in order to extract the Archaeological Research Design for the Antelope Valley Study Area 183 07A3822 Task Order 17 fruit pits. These pits were then boiled and then dried again. Subsequently, the softened pits were cracked open with a rock and the kernels were removed. At this point, the pits could be stored for future use (Timbrook 2007:152). Whether or not they had been stored, the kernels had to be leached before they were ready for consumption. After leaching, the kernels were boiled in stone bowls and, once they were cooked, the resulting mashed islay product was molded into cakes or balls which could keep for as long as a week. Given the substantial processing required before storage, islay berries are front-loaded resources. Small Seeds. Small seeds were abundant in the Antelope Valley floor and adjacent foothills before the twentieth-century changes in plant geography. Earle et al. (1995) proposed that these native plants were likely much more abundant in pre-contact times before the introduction of non-native plants, livestock grazing, and agriculture. Originally, the Antelope Valley playa and valley floor had grassland, shadscale, and saltbush scrub. Plants with small seeds included, but were not limited to, grasses (Carrizo grass - Phragmites sp.; Indian ricegrass -Stipa hymenoides; and desert needle grass Stipa speciose), bulrush (Scirpus sp.), bur-sage (Ambrosia dumosa), California buckwheat (Eriogonum fasciculatum), California pigweed (Amaranthus sp.), Chia (Salvia spp.), creosote (Larrea tridentata), fiddleneck (Amsinckia tessellate), Mojave monardella (Monardella exilis), pepper grass (Lepidium sp.), purslane (Sesuvium verrucosum), rabbitbrush (Ericameria nauseosa), rush (Juncus sp.), saltbush (Atriplex sp.), sagebrush (Artemisia tridentate), spurges (Euphorbia sp.), and thornbush berries (Lyceum andersonii). Most of these small seeds were available in the summer months. Their contribution to the daily diet of the pre-contact residents of the Antelope Valley is unclear because, compared to nuts, berries, yucca/agave and mesquite, there is relatively little information in the J. P. Harrington notes on small seed exploitation, with the exception of chia. This could suggest that small seeds may not have been staple items or, alternatively, as argued by Reddy (2009), the importance of the small seeds may have been deemphasized by these early ethnohistoric informants to focus on foods which had higher cultural value. In other words, nuts and berries were culturally perceived as more prestigious foods relative to small seeds; therefore, they were emphasized in the Spanish accounts. Alternatively, the lack of information on small seeds could also be a reflection of limitations in the ethnohistoric accounts which were informal and subjective. Small seeds were typically collected by beating them into baskets. Most of these native plant seeds have hard seed coats and need processing before consumption. These same hard seed coats helped their storage. Harrington’s (1986:98:98) informants described gathering chia in the Liebre Mountains on the southwestern edge of the Antelope Valley and caching the seeds in dry caves for months or years. The processing of small seeds with hard coats includes separating the seed coats by pounding and winnowing, and then grinding to make flour. Small seeds typically are front-loaded resources. Seasonality There was a pronounced seasonality in the plant diet of the prehistoric populations of the Antelope Valley. Typically, springtime was lean with mainly Yucca spp. available in the foothills. Summer months were more productive with islay and juniper berries on the hill slopes, and Archaeological Research Design for the Antelope Valley Study Area 184 07A3822 Task Order 17 mesquite/screwbean and seeds on the desert floor and playas. During the fall (October and November) pinyon and acorns were exploited. Seasonality of site use can be assessed by examining seasonal availability/abundance of plant foods: small seeds (generally spring/summer), berries (summer), and nuts (late summer/fall). The challenge with plant resources is that some of them can be stored, including acorns, piñon, and most small seeds. Therefore, their recovery from site deposits does not necessarily imply the season of their procurement. This is further complicated if the resource in question, for example, piñon or acorn nuts, are not locally available within the daily foraging range. This would imply that either the site occupants procured these foods through seasonal forays or through trade/exchange. Engendering Plant Exploitation Studies of changes and continuity in plant use trends have the potential to address issues related to gender. Nelson’s (2008) discussion of how resource intensification went beyond dietary needs in the Owens Valley is an excellent example of engendering plant intensification. Nelson’s (2008) arguments stem largely in response to the emergence of “prestige hunting” as theorized by Hildebrandt and McGuire (2012) wherein a significant portion of game was acquired from remote and upland locations which were part of logistical forays by males and not chance encounters by family units. Nelson (2008:169) considers how such participation of men in prestige hunting would give women “opportunities to play a larger role in family provision and perhaps settlement choice.” In such instances, when women began provisioning for the group, the resources were not shared as much as previously. Nelson (2008) suggests that post-3000 BP, women began to include marginal resources (such as small seeds) and new technologies (seed beads, pottery). If something like this occurred in the Western Mojave Desert and Antelope Valley, it would be expressed in the increased use of small seeds and yucca. Ethnohistoric Documentation of Plant Use There is considerable data on the ethnographic and ethnohistoric use of plants by Native Americans in California (Ball 1962; Clarke 1977; Ebeling 1986; Merrill 1918; Moerman 2010; Strike 1994; Timbrook 2007). The discussion in the previous section on plant use has been gleaned from these ethnographic and ethnohistoric documentation resources. In the absence of paleoethnobotanical data, archaeologists have often turned to these data to speculate on what plants were used prehistorically as food and for non-food needs. Bean (1972), Bean and Saubel (1972), Drucker (1937), Fowler (1986), Knack (1980), Laird 1976, Lanner (1981), Kelly (1932), Kroeber (1925), and others have excellent ethnographic information on plant procurement, processing, and consumption. See Table 2 in the Prehistoric Landscape section for plants used by the Serrano and their uses according to the Cahuilla. Ethnohistoric and ethnographic documentation indicates that piñon trees were important resources to some Native American groups, and occasionally groves of trees were considered family property Archaeological Research Design for the Antelope Valley Study Area 185 07A3822 Task Order 17 (Steward 1938). Similarly, Kelly (1932) wrote about family ownership of mesquite groves among Southern Paiute groups. Bean and Smith (1978b) have discussed how acorn and mesquite gathering involved several lineages under one lineage leader’s leadership. These are interesting aspects of Native American culture that need to be incorporated in archaeological interpretation. However, the specific paleoethnobotanical signatures of these behaviors need to be identified. In using and applying these data to archaeological contexts, it is critical to consider vegetation and culture change as it pertains to plant use. There has been significant change in vegetation with the arrival of the Spanish in California and the introduction of non-native plants and domesticates. If the plant remains do not meet the expectations of the ethnographic and ethnohistoric plant use patterns, it is imperative to consider cultural preference (a difficult aspect of culture to measure and quantify). Studies of prehistoric plant use in California have been held captive to the region's rich ethnohistoric record. Although modeling past human adaptations using ethnohistoric information is one effective avenue to understanding prehistoric behavior, ethnographic analogies are limiting and often one-dimensional. Faunal Analysis Identification Identifications of faunal remains are typically made by comparison to a reference collection of specimens, often at one or more museums. A wide variety of references are available that detail diagnostic features for specific animals. For example, identifications of diagnostic features of deer versus pronghorn are provided by Lawrence (1951) and Ford (1990). However, differentiating rabbit from jackrabbit is far more problematic because the only morphologically diagnostic feature is the lower third premolar (Baxter 2004:166) which is highly crenulated in Lepus californicus (black-tailed jackrabbit or hare) and moderately crenulated (anterior reentrant with at least two inflections) in species of Sylvilagus (rabbits) (Barnosky and Hopkins 2004:170). Many analysts use perceived size to differentiate; however accurate use of this technique requires knowledge of the natural range of variation in the local area. When no measurements or assessment of chronological age and gender are mentioned in the methods section, accuracy should be considered dubious. Quantification Most faunal studies quantify using number of identified specimens (NISP) and minimum number of individuals (MNI). While both tend to numerically over-represent rare species within a fauna and are subject to aggregation issues, relative frequency data are the most direct way to quantify faunas (Gifford-Gonazalez and Hildebrandt 2012:107). Due to the long history of studies using NISP and MNI, new quantification methods need to be utilized in addition to the standards, not replacing them. Archaeological Research Design for the Antelope Valley Study Area 186 07A3822 Task Order 17 A technique to utilize weight of archaeological specimens and convert them to meat weight was promoted by Glassow and Wilcoxon (1988) of the University of California at Santa Barbara for shell middens and later extended to vertebrate faunas. However, this method is fraught with problematic assumptions (Mason et al. 1998) and studies have demonstrated that intertaxonomic differences in processing, transport, and post-depositional preservation are significant factors that dramatically affect the utility of one-step conversion (Gifford-Gonazalez and Hildebrandt 2012:97). In addition, bone weight to meat weight conversion has been shown to be statistically invalid (Jackson 1998). Heat Modification Three classifications of heat-affected bone are commonly used: bone color-changed to brown/gray has been cooked and is often called heat-altered; blackened bone which has been burned; and white/light gray bone which is calcined. These differences can be significant in archaeological sites, but must be carefully considered as current evidence indicates that complex factors affect the color of heat-affected bone. Studies in open air (oxygen-rich) environments have shown that blackening does not occur on bone until the temperature of the fire reaches 450 degrees and calcining does not appear until the temperature reaches 800 degrees. Natural grassfires move very quickly, consuming the fuel as they go, and have relatively low temperatures of about 400 degrees. However, deliberate fires, made in one place and using wood for fuel, allow a bed of coals to form and may reach temperatures of 9001,700 degrees (Sillien and Brain 1990). Studies of human cremation practices have demonstrated that different results are obtained in closed (oxygen-starved) environments (Mayne Correia 1997). In a closed environment (covered with dirt) bone turned completely black at temperatures of 300-500 degrees and is calcined to white at temperatures in excess of 600 degrees (Wheeler et al. 1989). Heating bone to the level of calcining tends to cause shrinkage (5-20%) and cracking of bone (Mayne Correia 1997). Temperature, water exposure, soil chemistry, micro-organisms, and other factors have been shown to have dramatic decompositional effects on bone in a long-term experiment (Nicholson 1996). Taphonomy The process by which faunal materials are integrated into the depositional history of site is critical to the interpretation of assemblages. However, rarely are a comprehensive suite of taphonomic characters recorded or analyzed (Madgwick and Mulville 2014:255). Analysis of detailed recording of weathering, gnawing, and trampling can assist in separating depositional strata even when sediments appear uniform (Madgwick and Mulville 2014:261-262). In certain sites, non-human deposition may also impact the faunal deposition, which requires archaeologists to be thoughtful in their interpretation of the faunal assemblage. Owls, for instance, can play a large role in the deposition of leporid and rodent bones (Hocket 2005:715). Archaeological Research Design for the Antelope Valley Study Area 187 07A3822 Task Order 17 Organization of Animal Hunting Individual/Small Group Animal Hunting Animals taken for pelts such as carnivores, animals that require stealth to acquire such as deer, and animals that are solitary, such as chuckwalla, were hunted by individuals or small groups. Ethnographic information in conjunction with archaeological evidence indicates that hunting large animals was an adult male activity (Hildebrandt and McGuire 2012). Individuals used constructed rock or naturally-occurring rock formations as blinds along known animal trails for hunting deer and bighorn sheep. Hunters also used large brush to conceal themselves during individual or small group pronghorn hunts (Lubinski 1999:161). Brush concealment while hunting pronghorn was effective, as pronghorn lack visual acuity from a distance and are naturally curious, so they will approach anything new in their territory as long as it does not alarm them by scent or sudden movement (Lubinski 1999:160). Although pronghorn were most often hunted in communal groups, opportunist hunting by individuals or small groups may have occurred as well. Some ethnographic records indicated that pronghorn were desired more for clothing, as their light hides were preferred by various tribes for shirts, leggings, and moccasins (Lubinski 1999:161). Deer were sometimes hunted in small groups by driving them along trails where slip noose traps were placed (Heizer and Elsasser 1980:101). Both deer and bighorn sheep were sometimes driven down trails toward concealed hunters, where they would be killed using a bow and arrow at close range. Deer were also hunted using a deer head decoy on a human to get close enough to fire a projectile point efficiently (Heizer and Elsasser 1980:101). Although less common, deer and bighorn sheep were also hunted using pits, nets, and driving with dogs (Whitaker et al. 2017:3). Bighorn could also be attracted to hunters by banging a rock loudly to mimic the sounds of male sheep in combat. In contrast to men-only hunting practices, many smaller game species were likely exploited by children or those socially prohibited from hunting during scarcity of larger game species (Schollmeyer and Driver 2013: 449). Small lizards like chuckwalla can effectively be hunted by an older child or any adult using a sharpened stick since they do not flee for defense; they enlarge their bodies with air in an attempt to make it hard to retrieve them from rock crevices. Cottontail rabbits were hunted using a rabbit stick, nets, or blunt projectile point to stun them long enough for the animals to be collected and killed by snapping the neck to avoid damaging the pelt. Game birds were taken using small projectile points and possibly crescentics. Quail were taken using traps. Communal Animal Hunting Mass capture techniques give the highest return on investment. Information below indicates these methods were used for mammals, birds, and insects listed in decreasing order of processing investment. Pronghorn were often hunted by larger groups of people taking advantage of the natural curiosity of the animals. Heizer and Elsasser (1980:101-102) report that a banner on a long pole was constructed Archaeological Research Design for the Antelope Valley Study Area 188 07A3822 Task Order 17 a few miles from where herds were grazing. When the animals moved in the direction of the banner, they were driven into a brush enclosure. Pronghorn, deer, and mountain sheep were also driven by use of shouting and fire along defined pathways into brush corrals. Once the pronghorn were inside, a large net made of cordage, which they unknowingly passed over while entering the trap, would close the entrance (Wilke 2013:83). The pronghorn could then be killed at close range using a bow and arrow, spear, or be bludgeoned using clubs (Lubinski 1999:165; Whitaker et al. 2017:4). Group drives were often used to capture jackrabbits. Multiple birds could be captured by use of baskets and nets (Whitaker 2012:59). Flying birds were captured by stretching nets across flyways. Seasonal lakes and ponds that attracted waterfowl were exploited by using decoys to lure birds within range of slings or thrown nets and by placing a net below the surface of the water to capture diving birds (Whitaker 2012:60). Small food items such as fairy shrimp were captured using fine nets or baskets. These small food items, such as crustaceans and insect larvae, are invisible in the archaeological record. Role of Animals in Prehistoric Diet Based on archaeological collections, the mountainous fringe of the western Mojave Desert was home to black bear, bighorn sheep, deer, and chuckwalla. The valley floor was home to pronghorn, kit fox, jackrabbit, rabbit, squirrels, vole, rats, desert tortoise, iguana, and quail. Lynx, coyote, gray fox, and some others were found both in the mountains and valley floor. Seasonal lakes and ponds were home to ducks, geese, egret, heron, and fairy shrimp. Artiodactyls Pronghorn antelope (Antilocapra americana), deer (Odocoileus hemionus), and bighorn sheep (Ovis canadensis) were the artiodactyl species available within range of the Western Mojave Desert. Pronghorn antelope were known in prehistoric and historic times in the Antelope Valley. Large populations were known as late as the 1890s. However, a fish and game census in 1934 located only four females in the valley (Anderson 1934). By the 1950s the statewide population was so low that translocation efforts began (Brown et al. 2006). Pronghorn are most active in the daytime and their primary defense mechanisms are being a member of a herd and fast locomotion. The animals are known to be very curious and both prehistoric and modern hunters use a flag or pendant tied to vegetation to attract individual animals into range. Pronghorn were also hunted communally. Deer and bighorn sheep were hunted individually and likely did not leave the mountain areas. Local travel was probably needed to hunt these animals. An increase in large-game hunting in the San Francisco Bay area has been discussed using concepts from optimal foraging theory and intensification. As hunters depleted game around the large semipermanent villages near the Bay, they began to hunt further away in previously under-used habitats. With greater distance from the village, prey selection favored higher ranked species (large game, usually deer) that produced high return rates to offset the greater search and transport costs Archaeological Research Design for the Antelope Valley Study Area 189 07A3822 Task Order 17 (Broughton 1999; Hildebrandt and McGuire 2002). Another explanation for increased large-game hunting is based on costly signaling theory where prestige (non-food benefits) gained by the hunter is more important than provisioning (Hildebrandt and McGuire 2012). Non-food benefits include display of leadership, strength, and stamina and perception of prestige based on sharing food within a group. These qualities would attract both mates and supporters. This theory seems to require larger group size because within small groups these qualities are already well known by all group members. Big horn sheep bones have been identified in Late Holocene residential sites in the Owens Valley, far from where big horn sheep could be hunted. Hunters from these sites would have to travel long distances to hunt big horn sheep in the White Mountains. This great amount of energy expenditure is often more than the caloric return obtained from the meat from the big horn sheep when it is brought back to the residential base. The caloric return is actually higher if the hunters stay near the residential base in the lowlands and hunt small game (Hildebrandt and McGuire 2012:137). The explanation for this is that the increase in prestige was more important to the hunter than the net caloric return. Success in hunting big horn sheep may have been a costly signal indicating the hunter’s physical endurance, technical prowess, ecological knowledge, leadership ability, and generosity, to other members of the group. Advertising these characteristics may have resulted in higher social standing, greater mating opportunities, and higher reproductive success (Hildebrandt and McGuire 2012:137). Leporids Jackrabbit or hare (Lepus californicus) and cottontail rabbit (Sylvilagus sp.) comprise the leporids of the area. Jackrabbits are known to be active during the late afternoon and night and spend most daylight hours resting. Resting spots tend not to be reused and are most often are located in shade during hot months. In the Mojave Desert resting spots are sometimes extended into shallow burrows when no other shade is available (Costa 1976). Jackrabbits evade their natural predators by having no scent, protective coloration, and fast movement. Reproduction can occur year-round but tends to be most common in the first half of the year. Jackrabbits are known to travel to areas with more vegetation during winter months and travel distances of 5 km are common. Jackrabbits are also known to be attracted to seasonal water features in the Mojave Desert (Simes 2015). Communal drives were used to capture jackrabbits. By contrast, rabbits typically live in burrows and venture out to feed mostly at night. Rabbits were taken individually using a rabbit stick, nets or snares, or a blunt projectile point. Sometimes a hooked stick was used to pull them out of their burrows. Rodents Species of rodents identified in archaeological sites include woodrat (Neotoma spp.), vole (Microtus californicus), Mohave ground squirrel (Otospermophilus mohavensis), Antelope ground squirrel (Ammospermophilus leucurus), kangaroo rats (Dipodomys spp.), pocket mice (Perognathus spp.), deer mice (Peromyscus sp.), grasshopper mice (Onychomys torridus), and western harvest mice (Reithrodontomys megalotis). Numbers of rodents identified even to genus from archaeological sites Archaeological Research Design for the Antelope Valley Study Area 190 07A3822 Task Order 17 are usually low, and analysts sometimes have a difficult time distinguishing archaeological rodents from intrusive burrowing rodents. Other Mammals Other mammals known from archaeological sites include the bobcat (Felis rufus), coyote (Canis latrans), kit fox (Vulpes macrotis), gray fox (Urocyon cinereoargenteus), and badger (Taxidea taxus). Other animals probably available include black bear (Ursus americanus) and likely domestic dog (Canis domesticus). The use of bear and dog as food animals is generally considered unlikely, although pelts may have been taken. Birds The only bird ethnographically mentioned consistently as a food item was quail (Calipepla californicus). Raptors and colorful birds were likely hunted for feathers, but not used for food. Reptiles Desert tortoise (Gopherus agassizii) and pond turtle (Actinemys marmorata) were both identified archaeologically. Lizards as a group were identified, but not to genus or species. Both colubrid (Colubridae) snakes and rattlesnakes (Crotalus spp.) have been identified in archaeological sites. Marine Resources Small amounts of marine shell and shark present archaeologically (Earle et al. 1997:48-49) were likely items obtained in trade from the coast for decorative or utilitarian purposes. Insects Use of insects by Native peoples is well known ethnographically but not archaeologically, due to fragmentation and poor preservation. Known types of insects consumed include grasshoppers, crickets, flies, cicadas, mesquite beetles, ants, bees, yellow jackets, and lice. Larval caterpillars of Pandora moth, white-winged sphinx moth, and probably other types of lepidoptera, were consumed along with grubs and earthworms. Native populations had demonstrated knowledge of the seasonal and geographic availability of these resources. Roasting was a typical method of preparation, but insects were also boiled and then dried to be stored for later use (DeFoliart 1991; Skinner 1910; Sutton 1988c). Broad Trends in Subsistence Strategies in the Western Mojave Desert and Antelope Valley To aid in the identification of research questions, a brief summary of broad trends in the Native American prehistoric use of the Western Mojave Desert and Antelope Valley is presented below by cultural period (see the Chronology section). The discussion focusses on macrobotanical and faunal remains recovered from archaeological sites. The faunal discussion identifies trends and utilizes zooarchaeological resources recovered from Antelope Valley sites to define local expression. For this discussion, data from 23 sites with more Archaeological Research Design for the Antelope Valley Study Area 191 07A3822 Task Order 17 than 500 faunal remains in and near the Study Area are considered (Table 11). The proportion of specimens identified below the family level was exceptionally small in samples under 500 total specimens and thus they did not have the potential to contribute useful information. Sites were categorized by chronological component as reported by sources and by habitat as mapped by the California Department of Fish and Game (2013). To maximize the data available for chronological comparisons, animals identified as Leporidae, Lepus californicus and Sylvilagus sp. were combined as the Leporid Group. Animals identified as Artiodacytla, Ovis canadensis (bighorn sheep), Odocoileus hemionus (deer) or Antilocapra americana (pronghorn) were combined into the Artiodactyl Group. The Leporid Group varies from 46% to 100% of the identified faunal sample. The Artiodactyl Group represents from zero to 7% of the identified faunal sample. Bone that was affected by fire varies from zero to 86%, when reported, and does not appear to include unidentified fragmentary bone. Clovis Period (12,000 to 9500 BC) Sites of this period are known only from the northern Mojave Desert near China Lake. It is assumed that subsistence was based on group hunting of megafauna around pluvial lake margins. Low plant usage is assumed primarily because no milling tools have been found (Sutton 1996). There is no macrobotanical evidence of plant use by Paleoindian peoples in the Antelope Valley. Plants around lake margins would have included tules (Scirpus sp.), cattail (Typha sp.), and rushes (e.g., Phragmites sp.). No sites of this period are known in Antelope Valley. Lake Mojave Period (9500 to 7000 BC) Lake Mojave peoples practiced a generalized foraging economy that included use of lakeshores but was not limited to them (Sutton 2018:38). Diet would have diversified relative to the Clovis Period because multiple habitats and niches were exploited in addition to lakeshores. Nonetheless, Sutton (1996) states that virtually nothing is known about plant use during the Lake Mojave Period. However, the small numbers of ground stone tools recovered from Lake Mojave sites indicate some use of plant foods. Sutton et al. (2007) conclude that the use-wear on these tools suggest hard seed grinding. In Antelope Valley, there is no macrobotanical evidence to indicate which plants were exploited for food. Juniper, sagebrush (Artemisia tridentate), rabbitbrush (Ericameria nauseosa), Joshua tree (Yucca brevifolia), bur-sage (Ambrosia dumosa), and creosote (Larrea tridentata) could have been exploited during this period. Faunal subsistence data for this period indicate reliance on small game such as leporids and rodents with occasional use of large game. Protein residue studies also support this. Sutton (2018:38) notes that this contrasts with the flaked stone technology of this period which appears to be focused on large game (artiodactyls).

The site is in Joshua tree woodland in the northwestern part of the Study Area. The Leporid Group represented 74% of the identified fauna and the Artiodactyl Group only 7%. Rodents and bird were also present. Pinto Period (8250 to 2500 BC) Pinto Period sites were used during a period of more arid conditions and were commonly located on lake basins, waterways, springs, and in upland areas. Some residential bases had middens and there were a variety of simple, small resource extraction locations (Sutton 2018:39). An increase in ground stone tools likely indicates an increase in the exploitation of small and hard seeds (Sutton et al. 2007). As in the case of the Lake Mojave deposits, macrobotanical data for addressing plant food consumption are rare; instead scholars rely on ground stone tool assemblages to argue for plant processing and consumption. For example, according to Basgall (2000), ground stone is abundant in these deposits, and Sutton et al. (2007) suggest that access to plant resources may have determined site location. Macrobotanical data for the Pinto Period is very limited for the Mojave Desert. Sutton (1996) reports possible evidence of piñon exploitation based on recovery of piñon hulls from hearth features at the Surprise Spring Site (circa. 6500 BP). There is no macrobotanical data from sites in the Antelope Valley. Sutton et al. (2007:141) and Sutton (2007:24) have suggested that the Mojave Desert was abandoned at the end of the Pinto Period. However, whether this also applies to the western Antelope Valley is not clear. If the western and southern margins of the Antelope Valley Study Area were wetter than the rest of the Mojave Desert, it is likely that some plant foods such as juniper, yucca, pinyon, etc. would have been available for exploitation. Fauna used by Pinto groups in the Mojave Desert included leporids, artiodactyls, some rodents and some reptiles, including tortoise. Freshwater mussels may also have been utilized. Over the period, artiodactyl remains decreased while small game mammals increased (Sutton 2018:39). The only site in the Antelope Valley with a Pinto component (reported as Pinto/Gypsum) is CA-KER-2121 (Valdez 1995). The site is located in the east central part of the Study Area in alkali scrub. The Leporid Group constituted 100% of the identified faunal specimens. No artiodactyls were represented. Gypsum Period (2500 BC to AD 225) Resource productivity improved significantly in the Gypsum Period, compared to earlier times, and large areas of the Mojave Desert may have hosted large game, with piñon in the surrounding mountains and mesquite on the valley floor. The increased availability of food resources would have led to reduced mobility compared to the Pinto Period. Warren (1984) and Byrd et al. (2011) speculated that the residential stability of the Gypsum Period was due to the highly productive vegetation zones which would have served as residential bases from which logistical forays to more distant resource patches would have occurred. For much of the central Mojave Desert, piñon-juniper Archaeological Research Design for the Antelope Valley Study Area 194 07A3822 Task Order 17 and mesquite would have been the major plant resources exploited, while small seeds and agave would have been used on occasion, but not the major focus (Byrd et al. 2011). The Gypsum Period in the Antelope Valley is characterized by large permanent villages or seasonally occupied residential bases around the valley margins with smaller temporary camps on the valley floor for specialized activities (Sutton 1980; Warren 1986). A greater quantity of milling equipment is associated with Gypsum period sites, and the mortar and pestle were introduced during this period. Some of the plant resources that may have been used include mesquite, small seeds, and acorns and piñon from the foothills of the mountains to the south and west. Six midden samples from CA-LAN-1304 located in the Little Rock Canyon area south of Palmdale yielded a range of macrobotanical remains. The site has dates indicating occupation in the Gypsum and Rose Spring periods (1800-3920 cal BP and post-1350 cal BP) (Wohlgemuth 1995). The samples from Gypsum period contexts yielded piñon nutshell, manzanita berries (Arctostaphytos glauca), juniper berries (Juniperus californica), and wild cucumber (Marah sp.). Recent excavations in Antelope Valley by Kremkau and colleagues (2013) included macrobotanical analysis of eight samples from CA-LAN-1777, -1780 and -3873. Recovery was poor and included the recovery of only six carbonized seeds (including two saltbush seeds) (Reddy 2013). The eight features were roasting pits which most likely were used to cook animal foods that were wrapped in plant materials (i.e., the primary use of the features was not for plant processing). The low charcoal density (0.03 g per liter) from these features also attests to lack of carbonization during the use of the features. Five sites with prior faunal studies (CA-LAN-1208, Valdez 1992; CA-LAN-1296 Locus E, Christenson 1990; CA-KER-526, Hudson 1994; CA-KER-1175, Horne and McDougal 2003; CA-KER-2131, Valdez 1992) were entirely from this period. All were located in the east central or central portion of the Study Area with one in desert scrub and four in alkali scrub. Two of these five sites had one artiodactyl each and the others had none. Representation of the Leporid Group varied from 86 to 100% of the identified fauna and the Artiodactyl Group from zero to 1%. Other animals identified in order of abundance included rodents, lizards, snakes, desert tortoise, and birds. Rose Spring Period (AD 225 to 1100) The Rose Spring Period in the Mojave Desert is characterized by population increase (as indicated by increase in number of sites and site complexity) and an increase in plant use based on increase in the numbers of milling equipment and bedrock milling features (including mortar cups and slicks) (Sutton 1988a). Sutton and Jackson (1993) recovered burned resin of what they believe to be mesquite (Prosopis sp.) at CA-KER-2450 located near Rosamond and dating to the later part of the Rose Spring Period. The Rose Spring Period samples from CA-LAN-1304 yielded acorn nutshell, piñon nutshell, manzanita berries (Arctostaphytos glauca), juniper berries (Juniperus californica), and chia seeds (Salvia sp.). A Archaeological Research Design for the Antelope Valley Study Area 195 07A3822 Task Order 17 limited macrobotanical study at CA-LAN-1702 (with dates of 1205-1400 cal AD; 405-670 AD; 415-40 BC) on Edwards AFB yielded single carbonized seeds of cactaceae and Cheno/Amaranthus embryo, and pollen of Artemisia sp., Chenopodium sp., Pinus sp., and Prosopis sp. (Titus et al. 1997). Ten samples from three sites (EAFB-2014, EAFB-3128, and EAFB-3209) on Edwards Air Force Base yielded macrobotanical remains (Popper 2004). Samples from EAFB-3128 (dating to 1235-1201 cal BP and 1184 to 986 cal BP) yielded 36 carbonized seeds of Larrea tridentate and carbonized Yucca brevifolia fragments (23.60 g). EAFB-2014 samples yielded only a single seed of Atriplex sp.; and the samples from EAFB-3209 (dating to 937-743 cal BP), yielded carbonized seeds of Atriplex sp. (n=3); Larrea tridentata (n=17); and Yucca brevifolia (n=4). Only one site with a prior faunal study within this period is within the east-central Study Area (CAKER-1881, Pritchard Parker and Puckett 2004). Four additional sites are outside the study area to the north. One is located at Freeman Springs (CA-KER-6106, Williams 2009) in a Joshua tree woodland. Three are located in Sage Canyon, one in desert scrub (CA-KER-226, Cowie 2014) and two at higher elevations in pinyon/juniper woodlands (CA-KER-7432 and -7442, Cowie 2014). Each of these sites had one to five artiodactyls represented, and the percentage of the Artiodactyl Group varied from 2% to 6%. Representation of the Leporid Group varied from 47% to 98%. The relatively increased artiodactyl presence could suggest increased success in big game hunting with the introduction of bow and arrow technology. However, larger samples from well-dated sites would be needed to confirm. Other animals identified in order of abundance included rodents, lizards, coyote, snakes, and birds. Late Prehistoric Period (AD 1100 to AD 1769) Subsistence and settlement during the Late Prehistoric Period was probably similar to those of the ethnic groups seen at Spanish contact. Plant resource exploitation is marked by the introduction of ceramics for storage and the increased use of milling equipment (mortars, pestles). In the Antelope Valley and surrounding area, information about plant resource utilization by prehistoric populations can be gleaned from macrobotanical studies at a few sites. Sutton (1988b:73) reported recovery of fiddleneck (Amsinckia tessellate) from CA-KER-341, a dry cave site located near Rosamond. Matting made from tule (cf. Scirpus sp.) was also recovered from the site. Although there is no radiocarbon data from the site, Sutton suggests that it might have been occupied within the last several hundred years. Juniper berries (Juniperus cf. occidentalis) were recovered from CA-KER-733 (460+/-75 RCYBP) located in Antelope Valley (Sutton 1984, 1988:73). He states that juniper berries found at sites such as this may have been either included in hearths as part of fuel (berries attached to firewood) or as residues of food. In the northwest part of Antelope Valley on Edwards AFB, analysis of sediments from CA-KER-490 and CA-KER-2379 (dating from Rose Spring through Late Prehistoric Periods) by Reddy (1996) resulted in the recovery of small seeds only (Amaranthus sp., Erodium sp., Lepidium sp., Sesuvium verrucosum, and Stipa speciosa). Pollen analysis of samples from CA-KER–526 by Smith and Anderson (1994) did not reveal any evidence of cultural utilization of any particular taxa; instead, the taxa Archaeological Research Design for the Antelope Valley Study Area 196 07A3822 Task Order 17 represented in the sample are likely wind-blown. A single sample from a Late Prehistoric hearth at Site C1-M-1, north of the city of Rosamond and near the community of Mohave, yielded carbonized Allium bulb fragments and Erodium seed (n=1) (Kovacik et al. 2015). The role of plants in the Late Prehistoric Period diet can also be informed by data on plant use by contemporary societies. Some of the plant procurement and processing information discussed above is still known and practiced by living communities. See Table 2 in the Prehistoric Landscape section for plants used by the Serrano, along with their uses according to the Cahuilla. Four sites with prior faunal studies are located in the east-central part of the Study Area in alkali scrub (CA-LAN-2399, Pritchard Parker and Puckett 2004; CA-KER-500, Hudson 1996; CA-KER2916/17, Christenson 1991; and CA-KER-6047, Pritchard Parker and Puckett 2004) are entirely within this component. A fifth site is present in the pinyon/juniper woodland in the northwestern Study Area (CA-KER-733, Yohe 1984). Representation of the Leporid Group varies from 62% to 97% and the Artiodactyl Group varies from zero to 3%. Other animals identified in order of abundance included rodents, birds, snakes, lizards, fish, and birds. Mission Period (AD 1769 to AD 1835) There are no known macrobotanical data from sites dating to this time range. What is known about plant use in the Antelope Valley during this time period is gleaned exclusively from ethnohistoric resources. There are no faunal sites of this period known in the Antelope Valley. Summary A general pattern of plant use over time in western Mojave Desert and Antelope Valley can be summarized based on the meager macrobotanical data from archaeological sites. Direct evidence of plant use is present only from the last 1,000 or so years (beginning in the Rose Spring Complex). Plant use in the Clovis, Lake Mojave, Pinto, and Gypsum Periods is derived from indirect evidence (ground stone tool assemblages). Increase in ground stone tools in the Pinto and Gypsum Periods has led scholars to speculate that it indicates increased plant use; however, it is unknown whether it represents an increase in seed, nuts, or root foods. Starting with the Rose Spring Period, there is evidence of juniper, mesquite, and small seed exploitation; and evidence of piñon exploitation is not observed until the Late Prehistoric Period. Typically, reconstruction of plant use, in the absence of macrobotanical data, during the Late Prehistoric Period is based directly on ethnohistoric records (for example, Basgall and Waugh 2006; Sutton 1988a, 1991). While an abundance of flaked stone tools (projectile points and scrapers) suggests that artiodactyl hunting was important in all time periods, the limited faunal data indicates an abundance of leporids in all time periods with little or no evidence for artiodactyl hunting. It is likely that artiodactyl hunting was important, but that the artiodactyl bones did not become part of the archaeological deposits because they were burned for use as fuel. Some deer bones were used to make bone tools, including awls used to make baskets. Archaeological Research Design for the Antelope Valley Study Area 197 07A3822 Task Order 17 Research Questions and Data Needs The previous research summary clearly demonstrates the dearth of paleoethnobotanical and faunal studies in the Antelope Valley and western Mojave Desert. Reconstruction of past plant use is either speculated, based on inference from recovery of ground stone, or direct analogy with ethnohistoric documentation. Archaeological investigations in the Mojave Desert are lagging behind archaeological research in other areas of California in regard to regular collection of paleoethnobotanical data and inclusion of such data in reconstructions and interpretations of past human lifeways. Faunal studies suffer from inconsistent methodologies and lack of regional comparisons. As such, it is imperative that future archaeological investigations in the Antelope Valley be designed to recover data with which to address research questions about prehistoric plant and animal exploitation. Questions 1) What is the nature of plant usage, including changing intensity of plant use over time? Can plant exploitation over time be characterized as a generalized or a specialized strategy? Given the sparse macrobotanical data available from archaeological sites in the Antelope Valley, a critical part of every archaeological testing and data recovery project should include paleoethnobotanical investigation designed to address plant use. Our knowledge of plant use during the earlier cultural periods (Clovis, Lake Mohave, Pinto and Gypsum) is non-existent. If indeed there was change in the intensity of plant use over time, especially from generalized to specialized (resource intensification), this would have important implications for social, political, and economic aspects of the cultures. 2) Are there contextual associations between plant resources and features? The use of a specific plant can be discerned by the context of its disposal, and understanding the contextual associations of plant remains provides insight into the role of the specific plant(s) in the diet and subsistence system. For example, the recovery of high densities of carbonized Atriplex sp. ubiquitously from generalized midden, and high densities of mesquite only from features, indicate that these two plants had different roles. The ubiquitous recovery of Atriplex sp. indicates it was a plant that was highly used throughout the residential area, perhaps as fuel, fodder, and building materials, as well as food, and throughout the duration of the occupation. In contrast, the localized recovery of mesquite from features such as hearths suggests that it was used selectively (only as food) and perhaps only on occasion. Similarly, recovery of particular plant taxa from only ritual or mortuary contexts suggests plant use in association with religion and cosmology. As such, it is imperative that multiple samples are collected from every type of feature and generalized midden, because the context provides different insights into plant use. Archaeological Research Design for the Antelope Valley Study Area 198 07A3822 Task Order 17 3) What are the sources of seeds, and are there varying roles of plants in different contexts? An important issue in macrobotanical studies is discerning the source of seeds recovered from the archaeological contexts. The carbonized seeds recovered from cultural contexts can come from several sources, both cultural and natural in origin. Discerning the source is critical for archaeological interpretation because the source ultimately is the deciding factor on whether the plant was a food resource or not. For example, the recovery of carbonized saltbush (Atriplex sp.) seeds from a cultural midden could indicate its use as food, but it also could suggest that the seeds were incorporated into the site midden by a natural fire (depositional or post-depositional). Similarly, recovery of juniper berries from a hearth could indicate that the berry pits were tossed into a fire after consumption, or that they were part of the firewood used. Determining the source of seeds can be done by examining off-site sediments, and also by sampling multiple contexts at the site. 4) What is the timing of the beginning of mesquite exploitation in the Antelope Valley based on paleoethnobotanical data from archaeological contexts? Is there a relationship between mesquite exploitation and increased sedentism in the valley (Earle et al. 1997; Campbell 1996)? It is speculated that mesquite would have been an important food source starting in the Gypsum Period. Mesquite would have been available in the Antelope Valley beginning around 4,300 years ago (Schroth 1987). It has also been suggested that mesquite was important during the end of the Late Prehistoric Period (later part of Little Ice Age). There are no paleoethnobotanical data to support this hypothesis. The earliest mesquite macrobotanical remains were recovered from Rose Spring contexts; the interpretation of the importance of mesquite through the cultural sequence is based on ethnohistoric direct analogies. 5) What is the timing of intensive piñon and acorn use in the western Mojave Desert and Antelope Valley? How does it correlate with small seed intensification? Was there a shift to increased acorn use circa 1000 BC (Gypsum Complex) as suggested by use of mortars and pestles in foothill residential bases and desert floor temporary camps? What is the nature of the subsistence settlement system once intensive piñon and acorn exploitation are important components of the diet? How did juniper berry exploitation fit into the seasonal logistics with piñon and acorn exploitation? Based on recovery of piñon hulls from hearth features at the Surprise Spring Site (ca. 6500 BP), Sutton (1996) reported possible evidence of piñon exploitation during the Pinto Period in the Mojave Desert. Similarly, Byrd et al. (2001) have theorized that piñon-juniper and mesquite would have been important plant resources during the Gypsum Period. In addition, small seeds and agave would have been used on occasion, but probably were not the major focus during the Gypsum Period (Byrd et al. 2011). Warren (1986) argued that increased plant exploitation was one of the contributors for the establishing of large villages and specialized sites for plant procurement and processing during the Gypsum Period. None of these arguments are based on macrobotanical data; instead an increased frequency of ground stone tools and milling features are used as indicators of increased plant use. In the Antelope Valley, acorn, piñon and juniper occur around the valley margin along the slopes and foothills and could have been easily exploited seasonally by the valley inhabitants. Earle et al. (1995) Archaeological Research Design for the Antelope Valley Study Area 199 07A3822 Task Order 17 have used the distribution of glaucophane schist metates to argue for juniper berry and small seeds exploitation; however, this is not based on paleoethnobotanical data. Earle et al. (1995) and King et al. (1974) have argued that yucca buds, piñon cones and juniper berry processing would have to be done where there was ample fuelwood available, perhaps in close vicinity with juniper plants so that their wood could be used as fuel. This needs to be tested through paleoethnobotanical data. In addition to the question of when these resources first contributed to increasing diet breadth, it is also important to determine when intensive use and storage of these plant food resources began. 6) Can human occupation along water resources be determined based on recovery of wetland taxa and tubers? Were root foods important during the periods of increased wetness? The role of root foods, such as Brodiaea type complex, is difficult to discern because they often have elusive macrobotanical remains; yet, they would be valuable food resources when available. They were used by prehistoric populations in coastal and central California, but there is no evidence of their use in the Mojave Desert. Interestingly, Anderson (1997) has reported that ethnographic Native American groups of the Mojave Desert are not among those who consume roots of the Brodiaea complex. Ugan and Rosenthal (2016) argue that Brodiaea plants are present in the Mojave Desert seasonally, as observed during their survey of Pilot Knob Valley, Naval Air Weapons Station, China Lake, between January and March. Based on this recent research, it is plausible that root plants may have been available along water resources and during wet periods in prehistory. Depending on the density of their distribution and ease of harvest, root foods can fall on either end of the spectrum of low or high return rate foods. 7) Is brown or green cone piñon harvesting present in Antelope Valley prehistory? If so, is there diachronic change? Did subsistence intensification, including the beginning of green piñon cone processing and first use of mesquite and screwbeans, occur during the Rose Spring Period? Eerkens et al. (2004) proposed that piñon could have been harvested as brown cone or green cones. With brown cones less energy was required for harvesting, but the energy yield was also less. With green cones greater energy was required for harvesting but there was also a higher energy yield. Whether piñon is harvested brown or green also has bearing on caching (green cones have to be processed before storage), distance to residential camps (brown cones can be carried long distances and stored immediately), and group size and density of the resource patch. If Bettinger’s (1976) model for the Great Basin is applicable to Western Mojave and Antelope Valley, then piñon will become important only when other resources decrease, and piñon exploitation is necessary to increase the amount of food available. There is currently no evidence of piñon use by Antelope Valley prehistoric populations, and the earliest evidence for it elsewhere in the Mojave Desert is from Surprise Springs (ca. 6500 BP) (Sutton 1996). 8) Can resource intensification be identified through macrobotanical data in the cultural sequence of Antelope Valley? If plant resource intensification did occur, and is supported with macrobotanical data, did increasing intensification during the Late Prehistoric Period include transporting acorns to desert Archaeological Research Design for the Antelope Valley Study Area 200 07A3822 Task Order 17 temporary camps at springs for processing with mortars and pestles to provide food while obtaining desert resources? What is the role of small seeds in this potential intensification? Resource intensification is measured through the relative proportion of high-ranked versus lowranked taxa wherein there is an increase in the low-ranked resources (such as small seeds) compared to previous time periods. Plants foods that are low-ranked in Western Mojave and Antelope Valley include (but are not limited to) bur-sage (Ambrosia dumosa) and saltbush (Atriplex sp.), while highranked plant food would include Joshua tree (Yucca brevifolia), juniper (Juniperus spp.), mesquite (Prosopis sp.), pine (Pinus spp.), and yucca (Hesperoyucca whipplei). Although acorns have a high caloric yield, the major amount of processing time required prior to consumption makes them a lowranked resource (Codding et al. 2012) that was added only when necessary to support larger numbers of people and when storage was possible. Continued and/or changing focus on procurement of these groups of foods provides insight into resource intensification (use of foods that require more processing effort to produce more energy from plant foods for the group) over time. In addition to intensification, there is an upland-lowland dichotomy in Antelope Valley based on where specific plants are available. As such, intensification would also be indicated where acorns, piñon, and juniper are found at sites that are beyond the daily foraging range. If these foods are found at sites outside the daily foraging range, it indicates that these plant foods are being collected, potentially processed (fully or partially) at procurement locations and brought back to the residential bases or villages for additional processing and consumption. Such a strategy has implications for settlement systems, logistical planning, and socio-political interactions. Least-cost path analysis would also be useful in identifying patches/areas that would be logically more attractive for exploitation. 9) Do the archaeological features associated with plant processing according to ethnohistoric documentation, such as rock rings and roasting pits, have paleoethnobotanical data (macrobotanical and residue) which indicate they were used for this purpose? Rock features, earthen fire pits and roasting pits excavated at archaeological sites have been interpreted as plant processing activity areas (see for example Kremkau et al. 2013). The type of plant processing is distinct at each of these features (see Milburn et al. 2009). Correlating plants processed at different types of these food processing features would provide insight into intensification (labor invested in procurement and processing), seasonality, and continuity and/or change in processing methods, among other subsistence issues. 10) How can ground stone assemblages be used in modeling plant use in the Antelope Valley? Ground stone assemblages have been used by archaeologists to imply plant processing in the absence of paleoethnobotanical studies and lack of macrobotanical remains. The question remains, however, whether tools can be appropriate auxiliary data for plant remains to explain and interpret plant food procurement and consumption. First, ground stone tools can be used to process both animals and plants. These tools can be and have been used to pulverize small animals and extract marrow from mammal bone. Residue studies (lipids and starches) can discern what type of resource, Archaeological Research Design for the Antelope Valley Study Area 201 07A3822 Task Order 17 or a combination of resources, was processed by individual tools. Hand stones (manos) could have been used for small seed processing or for acorn and pinyon processing. Similarly, mortars and pestles can be used to process acorns, piñon, and small seeds. Only macrobotanical data can address this question. 11) Do changes in ground stone tools reflect changes in plant food use? 11a) Do the frequency and intensity of ground stone tool use change over time? If plant resource intensification is observed in the macrobotanical data, this change in subsistence should be expected to be reflected in the frequency and intensity of use of ground stone tools. With plant intensification comes the need for increased time spent on processing plants: parching, dehusking, and pounding and grinding seeds to make flour; shelling, pounding and leaching acorns, cracking and roasting piñon nuts, etc. This change should be reflected in both the frequency and intensity of use of ground stone tools. (11b) Do ground stone tool material, forms, and function change over time? Related to the question of frequency and intensity, with plant intensification comes the need to process plant foods for consumption and storage. Depending on the plant that is intensively collected/targeted, there would be an expected increase in the tools needed to process the plant. For example, if bedrock milling mortars and basins increase, but there is no increase in acorn nutshells, there is a lack of fit between these two data sets, and one has to look at alternative resources being used in these mortars. Similarly, if there is an increase in small seeds, but no change in ground stone tools, it may indicate lack of raw material to make manos and metates. (11c) What are the implications of changes in ground stone tool use for understanding the evolution of desert margin and desert subsistence systems? The prehistoric populations of the western Mojave Desert and Antelope Valley could have exploited three plant groups: yucca; piñon and acorns; and, mesquite and screwbean. Yucca processing requires few ground stone tools because the fruits, stalks and other plant parts were roasted in roasting pits (Louderback et al. 2013). Therefore, if there is intensification of yucca, this would be reflected in increased roasting pits and macrobotanical remains. Piñon and acorn nut processing would need cracking stones and ground stone (hand stone, mortar and pestle and/or bedrock milling basins and mortars) to make flour. Acorn and piñon intensification would be reflected in increased hand stones, mortar/pestle and bedrock milling features, accompanied by macrobotanical remains. If these resources are being processed at the procurement locations, such as seasonal camps on the slopes, this would be reflected in the material culture. Mesquite and screwbean processing requires cracking stones and ground stone (hand stone, mortar and pestle, and/or bedrock milling basins and mortars) to make flour, similar to piñon and acorn processing. In addition to these three main plant groups; small seeds of Carrizo grass –Phragmites sp.; Indian ricegrass Stipa hymenoides; and desert needle grass - Stipa speciosa), bulrush (Scirpus sp.), bur-sage (Ambrosia dumosa), California buckwheat (Eriogonum fasciculatum), California pigweed (Amaranthus sp.), chia Archaeological Research Design for the Antelope Valley Study Area 202 07A3822 Task Order 17 (Salvia spp.), creosote (Larrea tridentata), fiddleneck (Amsinckia tessellate), Mojave monardella (Monardella exilis), Pepper grass (Lepidium sp.), purslane (Sesuvium verrucosum), rabbitbrush (Ericameria nauseosa), rush (Juncus sp.), saltbush (Atriplex sp.), sagebrush (Artemisia tridentata), spurges (Euphorbia sp.), and thornbush berries (Lyceum andersonii ). In addition, juniper (Juniperus spp.) and islay berries (Prunus ilicifolia) were also collected for food. These seeds and berries were likely secondary food sources to the three main yucca, piñon, and mesquite foods. 12) Did hunting focus on artiodactyls in early time periods as indicated by hunting technology? Was there an increase in exploitation of artiodactyls concurrent with the advent of bow and arrow technology? Did hunting focus on smaller animals in later time periods? Was this shift gradual or abrupt? Based on toolkits, early peoples were hunting megafauna and shifted to artiodactyls about 11,000 years BP when megafauna extinctions occurred (Sutton 2018:44). There is no known association of tools directly with megafauna in the state (Jones and Kennett 2012:44). Paleontological materials should be carefully inspected for cut marks, patterned breaks and stages of combustion. Archaeological faunas should be fully identified, rather than sampled, to provide adequate statistical samples. The Antelope Valley data indicate an average presence of artiodactyls in the fauna of 7% in the Lake Mojave Period, 0.24% during the Gypsum, 3.3% during the Rose/Saratoga Spring Period and 1.09% in the Late Prehistoric Period. This is consistent with toolkit information, although the underlying samples are very small. Leporids have averages of 73% during the Lake Mojave Period, 93% during the Gypsum Period, 71% during the Rose Spring Period and 96% in the Late Prehistoric Period. Rodents by contrast have averages of 17% during the Lake Mojave Period, 2% during the Gypsum Period, 20% during the Rose Spring Period and 11% in the Late Prehistoric Period. The rodent samples have the highest likelihood to be confounded by intrusive, non-dietary animals. To address these questions, archaeological material should be separated by site component with associated radiocarbon dates. 13) What accounts for the sparse presence of artiodactyls in faunal assemblages? Is the high degree of fragmentation of bone and resulting sparse number of identified animals due to bones being used as fuel due to limited wood availability? Artiodactyl bone was utilized for tools like awls, scoops, and skin scrapers, yet these limited uses would not have affected all parts of the skeleton. Dogs could potentially have entirely eaten bones like vertebrae, but not longbone shafts. Even if longbone shafts were cracked for marrow, longbone shaft fragments should still be identifiable. Studies indicate that fresh terrestrial mammal bone, when added to fires started with dried wood or dried grass, produced consistent heat whether the percentage of bone was 25% or 50% and these partially bone- fueled fires burned for a longer time and produced more light than wood-only fires (Glazewski 2006:17-25; Vaneeckhout et al. 2013:129133). Experimental results showed that a single humerus in this type of combustion fragmented into 162 pieces, most less than 2 cm. Calcined fragments have been determined to rapidly deteriorate Archaeological Research Design for the Antelope Valley Study Area 203 07A3822 Task Order 17 and be underrepresented, but the amount of unburned bone is low (Costamagno et al. 2005:58-61). Both a high ratio of bone to charcoal and a high ratio of burned to unburned large mammal bone fragments are important evidence of use of bone as fuel (Aldeis 2017:195-196). Microarchaeological analysis can provide analysis of fuels used in hearths, including bone, and can evaluate maximum heating temperatures represented (Mentzer 2014). 14) Leporids appear to be very important at every desert site in the Mojave. Were leporids exploited all year long or seasonally? Can large numbers of leporids (especially jackrabbits) be associated with winter communal hunts associated with mourning ceremony clan gatherings? Do concentrations of leporids reflect local ecology rather than specialized site function? Is there evidence of change in use over time? Seasonality information for rabbits and jackrabbits is limited to presence of age classes through data on epiphyseal fusion (signaling end of bone growth in length). Both rabbits and jackrabbits breed year-round; however, both also exhibit a marked breeding season from January to June with young born in the summer and fall (Chapman and Harman 1972; Haskell and Reynolds 1947; Lechleitner 1959; Orr 1940). The most precise information available is from Lechleitner’s study (1959:67-68) in which extensive year-round trapping was done in northern California and the age and reproductive status of the animals determined. Young-of-the-year were scarce from January to April; numbers rose dramatically through the summer and then declined over fall. This was supported by investigations of the reproductive status of females captured which showed the percentage of animals pregnant to be highest in the late winter and early spring (Lechleitner 1959:74-76). In faunal samples from the Antelope Valley, few juveniles or subadults have been documented. At CA-RIV-399 a very large faunal collection contained sufficient juveniles to demonstrate late fall to winter use and dates indicated the site was revisited for hundreds of years (Gust 1991). In combination with lack of midden and other habitation features, but presence of human remains, the site was interpreted as an annual mourning ceremony location. In the past, large numbers of leporids in archaeological sites have been interpreted as specialized procurement sites (Christenson 1990; Yohe 1984). However, review of all available reports demonstrates the dominance of leporids in all Mojave sites. Biological information indicates jackrabbits are abundant in every habitat of the Western Mojave Desert (Mitchell et al. 1993), so local ecology is an unlikely reason for concentrations. Average percentages do vary across time with 73% during the Lake Mojave Period, 93% during the Gypsum Period, 71% during the Rose Spring Period and 96% in the Late Prehistoric Period. 15) Can resource intensification be identified through zooarchaeological data in the cultural sequence of Antelope Valley? Can residue analysis contribute useful information? Faunal resource intensification is measured by increased use of a greater number of smaller animals in spite of greater labor expenditure (Mason and Peterson 2014:122). There is currently no evidence of intensification, but this is due in large part to insufficient chronology and faunal sample size. Archaeological Research Design for the Antelope Valley Study Area 204 07A3822 Task Order 17 Residue analysis of projectile points might contribute useful information by showing what animals were hunted using the points. 16) Do the archaeological features associated with cooking according to ethnohistoric documentation, such as rock rings and roasting pits, have zooarchaeological data that indicates they were used for this purpose? Are faunal materials widely or narrowly distributed within a site? What are the stages of combustion observed? Rock features, earthen fire pits, and roasting pits excavated at archaeological sites have been interpreted as cooking features (Aldeias 2017; Kremkau et al. 2013). The type of cooking is distinct at each of these features (see Milburn et al. 2009). Correlating plants processed at different types of these food processing features would provide insight into intensification (labor invested in procurement and processing), seasonality, and continuity and/or change in processing methods, among other subsistence issues. Correct characterization of cooking features (Milburn et al. 2009) is necessary to evaluate this. Microarchaeological analysis can provide analysis of fuels used in hearths and can evaluate maximum heating temperatures represented (Mentzer 2014). This can be used to determine amount of heat applied to bones. 17) Do sites vary by ecological zone within the Antelope Valley? Are pronghorn found only in open valley areas? Are deer and bighorn found primarily in the Tehachapi and southern Sierra Mountains? Do small mammals and reptiles indicate local habitats? Do any animal foods indicate trade? All types of artiodactyls, including pronghorn, were recovered mostly in pinyon/juniper woodland sites (79%) in the Antelope Valley sites cited above. Other habitats with artiodactyls were alkali scrub (9%), desert scrub (7%) and grassland (3%). As discussed above, leporids do not appear to vary by site habitat. Few rodents or reptiles were identified to specific enough levels to evaluate this, but, for example, pond turtle and desert tortoise were found in alkali scrub and desert scrub sites, but not in woodland or grassland sites. No animals identified had restricted enough distributions to be solely trade items. An example of this would be softshell turtle which would have been imported from the Colorado River area. Data Needs Botanical Data Paleoethnobotanical data needed to address the above research questions pertaining to prehistoric plant use and diet include obtaining an adequate number and volume of samples for microbotanical and macrobotanical analyses. Some of the microbotanical analysis that would be valuable includes lipid and protein residue and starch analysis. Pollen and phytolith analysis, although useful for paleoenvironmental studies, often do not provide conclusive information about plant use by humans. Lipid residue and starch analysis can be conducted on artifacts and associated sediments. Artifacts such as projectile points and formed ground stone tools (hand stones, pestles, mortars, and basins) should be carefully wrapped, Archaeological Research Design for the Antelope Valley Study Area 205 07A3822 Task Order 17 preferably prior to washing, along with some associated sediment for lipid residue analysis. Lipids are collected from these tools and sediment to provide insight on what the tool(s) were used to process (Buonasera 2012). To do a rigorous study of lipid analysis, multiple tool types and associated sediment from different contexts should be included in the sampling. This will provide potential variability in tool use and perhaps also temporal use. Starch grain samples can be collected in the field or in the lab through the use of portable starch grain sample collection kits (Wisely 2016). Diagnostic features of starch grains are identified using cross-polarized and transmitted light, and morphological features of the grains are used to make identifications (Scholtz 2011; Wisely 2016). Starch grain can be recovered from artifacts (ground stone), milling features and soil samples. Again, as in the case of the lipids, multiple types of ground stone (pestles, hand stones, mortars, and basins) and associated sediment from different contexts should be included in the sampling. Macrobotanical data is obtained from the flotation of sediments, preferably unscreened sediment from cultural contexts. There are three important aspects of sample collection that have a direct relationship with the success of the study. First, the sample sizes should include a minimum of 10 liters of sediment per sample. This is particularly important for the western Mojave Desert sites which are typically shallow and have poor organic preservation. As discussed in the methods section above, the sampling should include a combination of bulk, pinch, and column samples. Bulk and pinch samples should be taken from features or occupation surfaces/lens. At least one column sample should be taken per site along the wall of a unit with the least post-depositional disturbance and best stratigraphy. The size of the column should be a minimum of 40 cm by 40 cm by 10 cm (if the site is being excavated in 10-cm arbitrary levels) along the best unit wall. To ensure that each 40 cmby-40 cm-by-10 cm sample is at least 10 liters, it would be advisable to first determine the actual volume before excavating the column. For a site with multiple components which are horizontally defined, a column sample should be taken at each of the signature units (units that define the components). The second factor, that has a defining effect on success of the study, is the number of contexts sampled for macrobotanical remains. Archaeological studies in the Mojave Desert tend to limit sampling for macrobotanical studies to a single or low number of contexts. This highly limits recovery rate and interpretative potential. Sampling for macrobotanical remains should have the same priority and importance as sampling for lithics (debitage and tools) and faunal remains. The third factor is the flotation recovery method employed and ensuring that trained individuals are responsible for recovery of the macrobotanical remains. Contamination is a very important issue to consider during flotation, as is adequately processing the sediment and ensuring that all organic material has floated. Often this requires multiple decanting and an experienced person who can estimate when the water processing can be terminated. Archaeological Research Design for the Antelope Valley Study Area 206 07A3822 Task Order 17 Zooarchaeological Data Zooarchaeological data needed to address the above research questions pertaining to prehistoric animal use and diet include obtaining adequate numbers of specimens for analyses from welldefined components. Principal investigators need to correctly classify cooking features and take samples for microarchaeological analysis. After sample size, the most important data need is for rigorous identification protocols. As mentioned above, a single tooth is the only defined morphological difference between jackrabbits and rabbits. Use of relative size without the basis of a study of local species cannot be justified and likely results in misidentification of subadult jackrabbits as rabbits. The basis of identifications needs to be clearly stated. Use of groups like leporids and artiodactyls is preferable to misidentifications. References can help by pointing out differentiating characters, but there is no substitute for use of a comparative collection when identifying. Qualified personnel should conduct identification and data collection and specialists should be used whenever appropriate. Fragmented faunal samples are typical, not unusual, in the Mojave Desert. A well-defined protocol should be established for classification of fragments and combustion status should be part of the data collected. Identifiable (to at least family level) fragments should be closely inspected for patterned breaks and cut marks. Samples for microarchaeological analysis should be collected from cooking features to allow determination of fuel type and maximum heat of that feature. Samples of bone outside of cooking features, especially if combustion is evident, are also important to submit for analysis. Faunal analysts need access to information like amount of charcoal collected from cooking features to evaluate whether bone was used as fuel. Knowledge of the habitat of sites is critical to evaluating whether animal foods were transported or used locally. Faunal analysts need access to relevant information on habitat for each chronological component. Archaeological Research Design for the Antelope Valley Study Area 207 07A3822 Task Order 17 Theme: Exchange and Conveyance Items of Exchange Items that were exchanged or conveyed by native groups in the Antelope Valley region are discussed in this section. Non-perishable exchange items that are encountered archaeologically are discussed first. Shell beads and other types of beads, lithic raw materials and artifacts, ceramics, asphaltum, and pigments are types of artifacts associated with inter-regional conveyance. There then follows a discussion of subsistence resources that were exchanged locally or regionally. These different items of exchange were associated with several major modalities of conveyance: direct access, conveyance through marriage and other social ties, and conveyance by specialist traders. These types of conveyance are discussed in a subsequent part of this section. Lithic Materials Information about the conveyance of lithic materials is summarized from the Lithics Sources section. Obsidian is one of the few types of raw lithic material that was not locally available. Obsidian was one of the most important lithic materials for making flaked stone tools in western North America during prehistory (Shackley 2005). Obsidian was not locally available in the Antelope Valley and was obtained from the Coso Range sources, located some 120 km north of the center of the Antelope Valley, likely a four- to five-day trip on foot (somewhat longer for an encumbered traveler). During the Lake Mojave and Pinto Periods, obsidian was not commonly used as a material for projectile points but was used to make flake tools and sometimes bifaces. During the Gypsum Period, obsidian was frequently employed to make dart projectile points as well as bifaces for use as both cutting and slicing tools. With the transition to the bow and arrow during the Rose Spring Period, smaller obsidian flakes were modified into arrow points. Obsidian continued to be used to make arrow points during the Late Prehistoric Period. Other non-local materials found in archaeological assemblages for the Antelope Valley include fused shale and its chemical cousins, which may have been imported from Monterey Formation sources in Ventura County (Grimes Canyon) and Santa Barbara County. Fused shale is a metamorphic rock that is semi-vitreous and was an important stone tool material for coastal southern California, particularly when obsidian was not easily accessible. Relatively little fused shale has been identified in Antelope Valley sites, but in some cases it may have been misidentified as obsidian. Rhyolite was locally available in the Antelope Valley from sources at Fairmont Butte and Rosamond Hills. It was used to make projectile points during the Lake Mojave and Pinto Periods. It was also used to make projectile points in later time periods, but possibly with less frequency. It was consistently used throughout all time periods for flake tools and bifaces. Archaeological Research Design for the Antelope Valley Study Area 208 07A3822 Task Order 17 Basalt is a fine-grained volcanic material that is more common in the central and eastern Mojave Desert where there is evidence of more volcanic activity. However, it was probably also locally available in the Antelope Valley. Like rhyolite, basalt was mostly desirable as a durable and strong material for tasks which did not require precise slicing or cutting. However, during the Lake Mojave Period and the Pinto Period, it was widely employed for crude projectile points that might have functioned as stabbing spear tips and atlatl darts. It was occasionally used for bifaces in later time periods. Cryptocrystalline silicates (CCS) (chert, chalcedony, jasper) are the most common lithic material used to make flaked stone tools in the western Mojave Desert. These materials are locally available throughout the Mojave Desert and can be viewed as one of the region’s key resources for exchange with other areas (Davis 1961). CCS sources are common at the east end of the Antelope Valley and in the Rosamond Hills (Sutton 1988b:15, 1993:1). CCS was used extensively for a wide variety of tool types throughout the entire prehistoric sequence of the Mojave Desert, including projectile points, bifaces, unifaces, and retouched and utilized flakes. Steatite (talc schist) and schist were utilized for a variety of ground stone tools and ornaments. An important source of both materials is found at a quarry in the Sierra Pelona Mountains located south of Leona Valley on the southern edge of the Antelope Valley. Steatite was commonly used for the production of stone bowls and mortars, as well as for stone beads, effigies, charmstones, pipes, and other artifacts. Schist was also used to make stone beads (see below). Steatite, and perhaps schist, from this quarry was an important raw material for both local consumption and trade outside of the Antelope Valley. Sources of lithic material in and around the Antelope Valley are shown in Figure 9. Asphaltum and Pigments Asphaltum is occasionally encountered at sites in the Antelope Valley (Kern County Museum n.d.; Sutton 1988b:43-45). Coastal groups generally used this material for waterproofing baskets, sometimes with the use of tarring pebbles. It was also used for attaching basketry collars to portable or bedrock mortars (Hudson and Blackburn 1981:112-117, 1986:166-167). Portable mortars with this asphaltum adhesive have been recovered in Antelope Valley sites (Kern County Museum n.d.; Sutton 1988b:43-44,58). In addition, it was often used as an adhesive and black background for the attachment of Olivella shell beads to objects, such as a wooden handle of a stone knife. Among the well-known sources of asphaltum are coastal deposits in the Goleta region and at Carpinteria, in Santa Barbara County. These were mined by the Chumash and are known to have been used by groups in the southern California interior (Hudson and Blackburn 1986b:165-166). Early ethnographer Erminie Vogelin was told by Tubatulabal of the Southern Sierra about trips to the Ventura coast in the nineteenth century, when asphaltum was brought back (Hudson and Blackburn 1986b:165). In mountain areas, both near the coast and in the interior, pine pitch was also gathered to be used as an adhesive and to coat the inside of water bottles. Pine pitch was also combined with asphaltum to make an adhesive (Hudson and Blackburn 1986b:163).

Prehistoric Lithic Sources 2015-075.017 Antelope Valley Research Design Asphaltum was also sometimes used as a pigment for face painting during mourning (Campbell 2007:74; Latta 1999:332). Cinnabar was used as a body paint as well in southern California, and sources were found in what was later the Calico Mining District near Barstow (Koerper and Strudwick 2002:3). A source of the principal body-painting pigment, red ochre (hematite), has been reported to be located in the Tejón region (Hudson and Blackburn 1986b:181). It is not known if there has been on-the-ground confirmation of this red ochre source. Mojave traders also brought red ochre with them as they traveled to the Antelope Valley, the southern San Joaquin Valley, and the Chumash region on the coast (Hudson and Blackburn 1986b:180-183). In 1774, Fr. Francisco Garcés visited the Colorado River and described Yavapai traders who were providing red ochre to Colorado River native people (Bolton 1930:381-382). This may have been one of the sources of the red ochre brought westward by Mojave travelers/traders. Both red ochre (hematite) and yellow ochre (limonite) have been recovered at CA-KER-303 in the northwest Antelope Valley (Kern County Museum n.d.). Red ochre was reported in a burial at CA-LAN-192 (Price et al. 2009:20; Sutton 1988b:52-53). Manganese pigment was also obtained by Mojaves at sources near Topock on the Colorado River and in Owlshead Canyon on Ft. Irwin (Campbell 2007:73; Drover 1979). The Chemehuevi also had quarries where manganese was mined (Laird 1976:131). There is no evidence for use of manganese pigments in the Antelope Valley. However, use of manganese pigment has been reported for the Gabrielino/Tongva and the Barbareño Chumash (Campbell 2007:73), which indicates that Mojave traders carried manganese pigment through the western Mojave Desert. Shell Beads In prehistoric California, shell beads figured prominently in economic activities as a medium of exchange, as well as in religious rituals and circuits of ceremonial prestation. In Southern California, beads manufactured from Olivella biplicata as well as Tivela and other clam species were particularly prominent. Strings of beads were possessed as a form of wealth, were given away or destroyed at mourning ceremonies, and/or were left at shrines as offerings to supernatural entities. The manufacturing of shell beads was especially associated with the territory of the Chumash in coastal areas of Ventura and Santa Barbara counties and especially in the northern Channel Islands. Kennett (2005:202-209) has reviewed the development of shell bead production in the northern Channel Island region, based in part on work by Arnold (1987, 2001). During the middle Holocene in this region, there is evidence that shell beads (modified whole shells) were used, but there is no evidence that they were locally manufactured. Kennett points out that significant evidence of shell bead manufacture is found only after 3000 BP, with a major increase in production between 1300 and 800 BP. This he associates with the development of microlith production on eastern Santa Cruz Island. This scenario suggests that the production and conveyance of Olivella shell beads underwent a transition from an earlier emphasis on the modification of whole shells (e.g., spire chipped, spire lopped, and barrel beads) ca. 8000 BP or earlier, to the later fabrication of smaller disc-shaped cup, lipped, and wall disc beads, that required drilling, beginning about 3200 BP. This conforms with Chester King’s (1990) typology for Southern California beads, which places a Middle Period Archaeological Research Design for the Antelope Valley Study Area 211 07A3822 Task Order 17 chronological unit at 3200-1000 BP that corresponds with the development of normal saucer and ground saucer beads and reflecting the shift to drilled beads. Most authors have suggested that shell bead production and conveyance in California began circa 7000-8000 BP. The shell bead typology developed by King (1990) for southern California commences chronologically with an Early Period spanning 8000-3200 BP (King 1983:68, 1990:28-30). King’s typology was based on burial-associated bead lots from the Santa Barbara Channel region, commencing with a Santa Rosa Island cemetery component dated at circa 7870 BP. He included spire-lopped Olivella biplicata whole shells in his initial Early Period bead inventory. He noted that he did not yet know what the earliest bead type phases might be for his Early Period, anticipating that earlier bead type dates for the Channel region might later be identified. Bennyhoff and Hughes (1987:160) note that Olivella biplicata spire-lopped beads are found in the western Great Basin as early as 7000 BP. Orange County Olivella barrel and cap beads dating from 4000-6000 BP have been found in Orange County, while Olivella spire-chipped beads date as early as 7000 BP (Gibson and Koerper 2000). Modified whole shell Olivella beads were prominent during King’s Early Period. In addition, clamshell disc beads are reported for as early as 8000 BP. Thus, it appears that modified whole shell beads could have been conveyed to the Antelope Valley as early as circa 7000 BP while drilled beads were conveyed after 3200 BP. However, much earlier dates for the conveyance of modified whole coastal southern California Olivella shell beads into the interior comes from four spire-lopped Olivella biplicata beads found at Fort Irwin in the central Mojave Desert. AMS dating of these beads yielded radiocarbon ages of 11,000-10,000 BP (Fitzgerald et al. 2005) during the Lake Mojave Period. These dates for whole shell beads in the Mojave Desert push back the antiquity of long-distance exchange in the region several thousand years. Nothing is known about where the beads were made or how they were conveyed to the central Mojave Desert during the Lake Mojave Period. Bennyhoff and Hughes (1987:155) have definitively shown long-distance conveyance of Olivella and other shell beads from the Channel Islands and southern California coast northward to Owens Valley and eastward across the Mojave Desert and into the southwestern and western Great Basin during their Early Period (4000-2200 BP). This approximate time period in the Antelope Valley (referred to as the Pinto Complex) is characterized by the presence of Pacific coast Olivella beads, but in limited quantities in comparison to later periods. The subsequent Gypsum Complex in the Antelope Valley and Mojave Desert dates to ca. 2000 cal BC – cal AD 200 [4000-1800 BP]) and appears to be characterized by population increases and broadening economic activities that may be a result of the movement of Takic speakers into the region (Sutton et al. 2007; also see the Social Differentiation section of this research design). A number of foothill and valley floor archaeological sites, including CA-LAN-192 (Lovejoy Springs), CA-KER-303 (Cottonwood Creek), and CA-LAN-488 in the southwestern foothills, have yielded elaborate interments dating from the late Gypsum Period and later periods. These featured large quantities of shell beads, including one case at CA-KER-303 of thousands of beads associated with an adult burial, and others at CA-LAN-192 and CA-LAN-488 involving child burials containing thousands of shell beads (Sutton 1988b:51-53, 55). Archaeological Research Design for the Antelope Valley Study Area 212 07A3822 Task Order 17 In addition to shell beads made from Pacific coastal shell, beads made from Olivella dama from the Gulf of California have been found at Antelope Valley sites. King (1983) noted small O. dama spire and base ground beads as being exchanged into southern California, including Orange County, as early as his Early Middle Period (1200 BC - AD 300). Gibson and Koerper (2000:50-51) note that O. dama shells were being imported to Orange County to locally manufacture barrel and cap beads during the last thousand years or so. King (1990:137) described Dentalium neohexigonum beads found in the Santa Barbara Channel region in Middle Period and Late Period contexts. He also noted beads of this species dating from his M4 and M5 time periods (AD 700-1150) having been found at Oro Grande on the Mojave River. Earle et al. (1997:171) listed seven Dentalium beads as having been reported for Antelope Valley sites as of that date. An additional Dentalium pretiosum bead fragment was recovered at CA-LAN-192. Additional Dentalium beads, not yet identified as to species, have been excavated at CA-KER-303 (Kern County Museum n.d.). Other shell genera and species identified as utilized to fabricate beads include Tivela stultorum (Pismo clam), Haliotis (abalone) spp., Mytilus californianus (mussel), Megathura crenulata (keyhole limpet), and Dentalium spp. King (1990:184-192) discussed the use of Tivela stultorum, Haliotis, and Mytilus beads, along with Olivella biplicata wall beads, among southern California Takic groups and the Yokuts during the Late Prehistoric and Protohistoric Periods. He suggested that all of these classes of beads tended to be larger in size in these latter areas, raising the possibility of some non-Chumash local manufacture. He noted the occurrence of Pismo clam disc, cylinder, and tube beads in the Antelope Valley area, along with abalone epidermis disc beads. Clam disc beads, along with abalone epidermis disc beads and mussel disc beads have been recovered at CA-KER-303, in the northwestern Antelope Valley (Kern County Museum n.d.). King also proposed that the dark-colored mussel disc beads had been developed by the Late Prehistoric Period to be strung with white Olivella wall disc beads to provide color contrast, and that clam shell wall beads were a late spinoff of Olivella wall beads, useful because of their greater thickness when strung on a necklace. He saw the late development of abalone epidermis disc beads as a sort of improvement on mussel shell beads, because they provided enhanced red or green color contrast when strung with white Olivella or clam shell wall beads. He treated these multicolor bead necklaces as relatively rare and indicating reciprocal prestations of high value gifts between members of the political elite. Within California, clam shell disc and cylinder beads were made from the shell of the Pismo clam (Tivela stultorum) and other clam species, including Saxidomus. King (1990) has described Tivela stultorum disc beads made in the Santa Barbara Channel region dating from his Early Period and Phase 1 of the Middle Period, and cylinder and tube beads at the beginning of his Middle Period. After a hiatus, all of these types reappear in the Late Period (King 1990). These types of clam shell beads were rare outside of the Santa Barbara Channel region during the Early and Early Middle Archaeological Research Design for the Antelope Valley Study Area 213 07A3822 Task Order 17 Periods King's observations on use and distribution of Tivela clam shell beads in Southern California have been reviewed above. Clam shell disc beads were very commonly used in central California, as a medium of value in the Protohistoric Period and after the arrival of the Spanish. Von Der Porten et al. (2014) observe that clam shell disc beads become common in central California around AD 1500. They note that during earlier times elite-based trade networks conveyed Olivella beads while in later times (circa AD 1500) clam shell beads were used as a medium of exchange in a more 'monetized' system of movement of goods (Frederickson 1994; Hughes and Milliken 2007; Rosenthal 2011). Relevant to the Antelope Valley region are ethnohistorical indications that the southern Valley Yokuts and the Tubatulabal of the southern Sierra shared in this use of clam shell 'currency', an alternative to the Chumash use of Olivella disc beads and, in historic times, rough disc beads, for the same purpose. Yokuts consultants of Latta (1999:318-324) described the use, value, and origin of what were described as Pismo clam (Tivela stultorum) disc beads. These were recalled as having been mainly obtained from the Chumash by way of the Cuyama Valley, although some fabrication may have been carried out locally. Voegelin (1938:52) noted the accumulation and use by the Tubatulabal of clam shell disc beads as a form of wealth, and that these were obtained from the Chumash. She stated that the Tubatulabal knew about Olivella shell beads but did not use them as 'money'. This raises the question as to whether some groups or communities in the Antelope Valley region may have used significantly larger quantities of clam shell beads than others during the Late Prehistoric Period. In summary, from Gypsum Period times to the end of the Late Prehistoric Period, drilled shell beads which originated in Chumash areas are recovered from sites in the Antelope Valley in considerable quantity. Olivella and other bead types have been important as archaeological markers for longdistance conveyance, as indicators of political and economic evolution in native California, and as chronological markers within site deposits. The testing of the chronological typologies that make beads so important is a key goal of any regional research design involving bead analysis. As Milliken and Schwitalla (2012:6) emphasize, “naming beads is no substitute for metrics”. In other words, measurement and description of local specimens is always necessary to test the received wisdom of standard chronological typologies. Dahdul (2002:60-63) provides a relevant object lesson on this from another desert area, the Coachella Valley. There she found that her independent dating of beads revealed chronological discrepancies with standard dating typologies. Thus, the necessity of testing the local applicability of typologies derived from archaeological data in other regions. Stone Beads The appearance of chlorite schist stone beads in cemetery contexts in the Chumash region was dated by King (1990:133) as beginning at around 200 BC. He noted that from this time, the use of this type of bead was more frequent among Uto-Aztecan speakers to the east of the Chumash. During his late Middle Period, equivalent to the Rose Spring Period, relatively large globular, cylinder, and tube beads of black chlorite schist were common burial furnishings (King 1990:133-144). During the Late Archaeological Research Design for the Antelope Valley Study Area 214 07A3822 Task Order 17 Prehistoric Period, he observed a decrease in the size, and some decrease of abundance, of these bead types. In the Antelope Valley stone beads are present, but less abundant than shell beads (Earle et al. 1997:166, 167-168; Price et al. 2009:104). These are frequently fabricated from chlorite schist, found in deposits in the Sierra Pelona region on the south side of the Antelope Valley. Sites located along Amargosa Creek, in the San Andreas Fault rift zone in the foothills to the west of Palmdale and to the north of the Sierra Pelona ridge, served as workshops for the making of beads, pendants. and other schist objects (Padon et al. 1998). Sites of this kind in that area, dating to the Rose Spring Period and later, include CA-LAN-948, CA-LAN-951, CA-LAN-953, and CA-LAN-954 (Price et al. 2009:3, 21). These chlorite schist beads are found widely distributed in the valley. King (1990:178) mentioned that at CA-KER-303, in the northwest valley, both globular and disc types of black chlorite schist beads were found. King noted a similar Middle Period presence of chlorite schist beads on the Mojave River at the Oro Grande site (King 1983:80-81). Glass Beads Glass beads made in Venice were used by the Spanish in southern California during the early colonial period, between 1769 and circa 1805, as gifts to non-missionized native people. Both military commanders and Franciscan missionary fathers used gifts of beads as an inducement for native cooperation, especially in the case of native chiefs. Two classes of beads, cane beads and wire-wound beads, were used during this period (King 1990:194-195). Common cane beads were copper blue, cobalt blue, and copper green. Wire-wound beads, more expensive, included translucent red beads. Expeditions visiting native communities during the colonial period often distributed glass beads. It is possible that when Capt. Pedro Fages passed through the southern Antelope Valley in 1772, he provided native people at the village of Kwarung with glass beads. When Fr. Francisco Garcés visited the community in 1776, he noted "signs" that Fages had passed that way (Coues 1900:I:267-270). King (1990:194-195) noted that in the period of final recruitment of native people to the Franciscan missions in the Chumash region, around 1805, there was a marked decline in the circulation of glass beads. At this time, there was a revival in the manufacture of shell beads and their use as a form of wealth. This fabrication occurred at missions such as San Buenaventura. In the nineteenth century, non-missionized native groups living on the interior fringes of Spanish/ Mexican society sometimes received glass beads, including as payment for seasonal casual labor on coastal ranchos. Thus, trade beads reached interior desert areas like the Coachella Valley and the lower Colorado River. In the Antelope Valley, the numbers of trade beads recovered at archaeological sites has been limited. Although 920 glass beads were mentioned for the greater Antelope Valley region in Earle et al. (1997:171), these were actually recovered from a single site located beyond the eastern boundary of the Antelope Valley Study Area. One or a few glass beads have been found at CA-LAN-298, CALAN-184, and CA-LAN-192 (Price et al. 2009:106). None had been found at Edwards AFB as of the late 1990s. Because of the limited number of glass beads recovered archaeologically, Sutton (1988) had speculated that settlements in the valley might have been abandoned prior to the arrival of the Archaeological Research Design for the Antelope Valley Study Area 215 07A3822 Task Order 17 Spanish in California. However, accounts of Spanish exporers show that this was not the case (see Ethnohistory section). Identifying glass beads within bead assemblages at Antelope Valley sites is important for two reasons. In the first place, it provides evidence for site occupation in the late eighteenth century. In addition, the presence of glass beads as a stratigraphic marker may be useful in helping to determine whether the uppermost strata of local sites had been damaged or removed through earthmoving or other modern activities. Sites located on ranch properties are often subject to varying degrees of such surface disturbance. Shell Ornaments (Other than Beads) Keyhole limpet (Megathura crenulata) ring ornaments are described by King (1990:124-127, 250-255). He dates their presence at Southern California sites as spanning a period from circa 200 BC to AD 1650, with their being much more frequently found during the period from circa 200 BC to AD 1100 than after that date. Earle et al. (1997:171) list nine whole rings or fragments reported for Antelope Valley sites at that time, and Price et al. (2009:102) report one from CA-LAN-192. However, a number of these ornaments were also recovered at CA-KER-303 (Kern County Museum n.d.). Ceramics Ceramics generally are not a common component of prehistoric sites in the Antelope Valley, especially in the western portion of the valley. Ceramic types that have been found at sites in or adjacent to the greater Antelope Valley region include Owens Valley [Great Basin] Brown Ware, Southern California (Tizon) Brown Ware (also known as Tizon Brown Ware), Intermediate Desert Wares made in the Mojave Desert, and buff ware ceramics originating on the Lower Colorado River, as well as those from the Southwest. Owens Valley Brown Ware was produced by Numic populations in the Eastern Sierra region after circa AD 1350-1400 (Eerkens 2003b:20; Griset 2013:17). Southern California Brown Ware may have originated at a relatively early date in the California Transverse Ranges after AD 700, according to Griset (2013). It became more common during the Late Prehistoric Period, and was produced by the Cahuilla and Serrano, among other groups. A variant of this ware was also made in the nineteenth century by Kitanemuk potters living beyond the northwest margin of the Antelope Valley (Earle and Wiewall 2011). In analyzing ceramics recovered in the Antelope Valley, Griset has introduced the concept of the Intermediate Desert Ware (Griset 2013:7; Price et al. 2009). These intermediate characteristics include use of Mojave Desert clays intermediate between clays of sedimentary origin and residual clays (surface clays as found in lake and river beds, usually quite plastic) and with clays that have colors between buff and brown when fired. In a study of 263 sites in the Antelope Valley where test excavations were carried out (126 of these were within Edwards AFB). It was found that 55 sites contained ceramic fragments (Earle et al. 1997). The majority of these were located in the eastern and southeastern portions of the valley. The most common ceramic sherd types (over 90%) at these sites were identified in site reports as Tizon Brown Ware and Brown Ware. The Griset (2013) typology, which depends on clay anlysis, was not used and, therefore, it is not clear whether these sherds would be classified as Southern California Brown Ware Archaeological Research Design for the Antelope Valley Study Area 216 07A3822 Task Order 17 or Intermediate Desert Ware. In addition to these brownwares, a small percentage of the sherds (n=20) are identified as Lower Colorado (Buff) Wares. One Anasazi Black-on-Gray piece from the Southwest was identified. A detailed analysis was also carried out for ceramic materials recovered from CA-LAN-192, Lovejoy Springs, on the floor of the Antelope Valley south of Edwards AFB (Griset 2013; Price et al. 2009:109-137). The analysis identified 58 sherds of Southern California (Tizon) Brown Ware, 16 sherds of Desert Intermediate Ware and Cronese Red-on-Brown, and 39 sherds of various Lower Colorado Red, Red-on-Buff, Buff, and Stucco Wares. In addition, a single sherd of Hohokam Buff was also identified. Of this total, five of the sherds had been re-ground into discs (three of them perforated), and two others had been shaped for use as scraping or grinding tools. Many of the Southern California Brown Ware and Lower Colorado sherds, as well as the Hohokam sherd, had been recovered on the surface of the site, indicating a relatively recent date for these. The analysis concluded that the Southern California Brown Ware and the Lower Colorado River ceramics were non-local in origin (Griset 2013:7-8; Price et al. 2009:132-136). The clays used to produce the Desert Intermediate Ware, however, were likely obtained locally within an 80-mile (E-W) by 60mile (N-S) area encompassing the Antelope Valley. The materials examined in Price et al. (2009:124-126) appear to have come from relatively widemouth vessels, possibly appropriate for cooking, rather than from narrow-necked vessels appropriate for storing or transporting water. It is possible that the primary purpose for the non-exotic locally produced brown ware vessels was for slow cooking or simmering. In the case of the historic-era fabrication of ceramic vessels by Kitanemuk women, the objective was to create vessels (i.e., vessels that could substitute for traditional stone cooking ollas) for cooking nutlets from islay or holly-leafed cherry (Prunus ilicifolia) berries (see the Subsistence section) and other foods that required extended cooking (Earle and Wiewall 2011). Among the Chemehuevi of the Mojave Desert, ceramic vessels were used for a similar purpose. They were very scarce, valuable, and subject to breakage, which helps explain their scarcity (Kelly 1953). It was ethnographically reported that such vessels were sufficiently scarce and sufficiently important and valuable that different local Chemehuevi bands would lend and borrow a single vessel back and forth between them. Such bands also preferred to avoid camping in rocky places in order to reduce the risk of breaking these fragile ceramic vessels. Such a scenario, and the specific cooking use that such vessels might be put to, might explain why they were important, despite the possible exchange or importation of these vessels in relatively small numbers and their use in relatively small numbers. If these vessels were also an alternative to stone cooking pots used for slow cooking, the local availability of steatite for bowl manufacture might offer an alternative to the use of such ceramic vessels. In the foothills and outlying canyons of the southwestern Antelope Valley (particularly Sierra Pelona), steatite sources and stone bowls made from this material are common, while ceramic materials are not. Local production of indigenous ceramic wares in Southern California appears to have begun at a relatively late date, within 400-500 years or less prior to Spanish contact. However, for desert areas located on routes of travel and exchange from the direction of the lower Colorado River and the Archaeological Research Design for the Antelope Valley Study Area 217 07A3822 Task Order 17 Southwest, it is possible that ceramics of an earlier date may have been conveyed from those regions (Sutton 1988b:46; Warren 1984:390-391,401,403). Of particular interest for the Antelope Valley region is the evidence of occupation of sites by the Anasazi at Halloran Springs, east of Baker, California in the eastern Mojave Desert beginning circa AD 700 in the Rose Soring Period and extending into the early Late Prehistoric Period (Sutton et al. 2007). Thus, the possibility exists that ceramic wares culturally associated with the Southwest may have been conveyed to the Antelope Valley region during this time. It is possible that Anasazi Gray Ware was being exchanged for shell beads from the Pacific Coast at this time (Leonard and Drover 1980:252-253; Rogers 1929; Smith 2002:21). The Lower Colorado River Ware sherds at CA-LAN-192, Lovejoy Springs, identified by Price et al. (2009), do not provide firm dates for their conveyance to the Antelope Valley. They initially appear in ceramic chronologies circa AD 700-1000 but continued to be made through historic times. Their appearance in surface contexts may indicate a late date of arrival in the Antelope Valley. The Mojave River was an important part of the route from the Colorado River to the Pacific Ocean used by long-distance traders. Evidence of movement of ceramics along the river as early as AD 900 is mentioned in Price et al. (2009). However, it is noted that extensive excavations at the upper Mojave River site of Oro Grande, occupied during circa AD 850-1300, did not yield ceramic materials (Rector et al. 1983). As of the late 1700s, Desert Serrano occupied the length of the Mojave River, and hosted long-distance shell bead traders from the Mojave villages on the Colorado River. Residents of those Colorado River villages produced Yuman-style ceramics for exchange to neighboring Chemehuevi desert groups. Nevertheless, there are no ethnohistorical testimonies about Mojave ceramics being carried across the desert toward coastal California by these Mojave traders. The ceramics found along the Mojave River identified by Price et al. (2009) as Southern California (Tizon) Brown Ware may possibly have originated in other areas of Southern California, including among the Mountain Serrano and the Cahuilla. Travel Routes and Trails The following section outlines the network of trails that linked different areas of the Antelope Valley and connected the Valley with other regions. These have been documented for the Mission Period, but given the regional topography, were probably used in earlier times. Routes of major trails are shown in Figure 10. A major northwest-southeast trail extending the length of the Antelope Valley linked the upper Mojave River with villages on the south side of the Antelope Valley, and with trails connecting to the southern San Joaquin Valley. This trail ran from the west end of the valley, in the vicinity of Quail Lake, southeastward along the south side of the floor of the Valley, crossing Little Rock Creek and Big Rock Creek to reach the village of Atongaibit on the upper Mojave River. This route appears to have been followed by Friar Zalvidea and his expedition in 1806. Testimony from the 1840s indicates that this trail was used by Mojave shell bead traders to reach the trails in the western Antelope Valley that led to the Tehachapi Mountains and Kitanemuk and Kawaiisu territory (Jackson and Spence Archaeological Research Design for the Antelope Valley Study Area 218 07A3822 Task Order 17 1970). This trail was also a major route for travel and conveyance between the Serrano of the San Bernardino Mountains and of the Mojave River and the Serrano-speaking villages of the southern Antelope Valley. It is possible that an additional trail, further north, may have run due eastward toward the Mojave River (General Land Office 1855). A variant of this trail ran southeastward from Lake Hughes along the San Andreas rift zone past Elizabeth Lake and through Leona Valley, along Amargosa Creek, then through Anaverde and Alpine Springs and Barrel Springs to reach Little Rock Creek and rejoin the main South Valley trail. This trail connected a number of villages in the rift zone area. Portions of it were used by Fages in 1772, Palomares in 1808, Frémont in 1844, and the Pacific Railroad Survey in 1853 (Palomares 1808; Jackson and Spence 1970; Blake 1856). Several trail systems linked the Western Antelope Valley with the Tehachapi Mountains (the territory of the Kitanemuk and Kawaiisu) and the southern San Joaquin Valley. Two trails linked up to pass through the original Tejon Pass and reach the Kitanemuk settlement at Tejon Canyon in the foothills of the southern San Joaquin Valley. One of these trails linked to a third trail that reached the Tehachapi Valley. Mojave and Yokuts long-distance traders use these routes of conveyance, and the Kawaiisu may have done so as well (Latta 1999). From Lake Hughes, on the southwest side of the Antelope Valley, a major north-south trail crossed the Valley to reach Willow Springs, west of Rosamond Hills. From here one trail ran northward to Oak Creek Pass and Tehachapi Valley in the territory of the Kawaiisu. A second trail from Willow Springs headed northwest to reach Twin Lakes and the old (not the modern) Tejon Pass, to reach the territory of the Kitanemuk. Friar Garcés followed this latter route from Lake Hughes to Tejon Pass and the territory of the Kitanemuk in 1776 (Coues 1900). At the west end of the valley, the main trail passing Quail Lake intersected further west with a south to north trail running from the direction of the Santa Clara River drainage and the territory of the Ventureño Chumash. The trail passed northward past Frasier Park and Kashtiq Chumash territory at Castac Lake to descend the Grapevine to reach the floor of the southern San Joaquin Valley, where another Interior Chumash village was located (Harrington 1986; Blake 1856). This trail was part of a major Chumash exchange and travel corridor linking coastal Ventureño Chumash with Interior Chumash of the southern edge of the San Joaquin Valley.

Native Trails Discussed in Text 2015-075.017 Antelope Valley Research Design Another important north-south trail branched off from the trail connecting Tejon Pass with Willow Springs, to descend the slopes of the Tehachapi Mountains on the northwest side of the Antelope Valley. It angled downslope to the southwest to reach the west end of the valley, climb Liebre Mountain to the south, and head south to the Santa Clarita Valley region. In the historic era this trail provided communication between native settlements in the Tejon Canyon region and the Santa Clarita Valley and Mission San Fernando further south. This trail was described by Kitanemuk consultant Maria Solares to ethnographer John Harrington, and a part of it was mapped by the Wheeler Survey in the late 1870s (Harrington 1986; Wheeler 1879). To the southeast of Liebre Mountain another trail ran southward from the village of Kwarung (Quiriniga) at Lake Hughes to descend Elizabeth Lake Canyon in the direction of the Santa Clarita Valley. This trail was used by José Palomares during an 1808 military expedition that visited the Antelope Valley (Palomares 1808). Another trail descended San Francisquito Canyon from the east end of Elizabeth Lake towards the Santa Clarita Valley. During the era of Mexican rule, this trail was reportedly used by ox carts to reach the southern San Joaquin Valley, and it was the main 'road' from Los Angeles to San Francisco in the 1850s (Latta 1976:57-58). Further to the southeast, on the east side of Leona Valley, another trail to the Santa Clarita area descended Bouquet (Buque) Canyon. South of Palmdale, a major trail route passed southward through Soledad Pass and descended the headwaters of the Santa Clara River to reach the Santa Clarita region. The Soledad Pass trail was described by the Pacific Railroad Survey in 1853, and a portion of it was mapped by General Land Office surveyors in 1855 (General Land Office 1855; Williamson 1856). Further east, another south-to-north trail appears to have passed from the canyon of Big Rock Creek northward across the floor of the valley past Lovejoy Springs to Buckhorn Springs, as described by Serrano consultant Santos Manuel (Harrington 1986:III:101). Another trail ran westward, probably from Buckhorn Springs, along the north side of Rosamond Dry Lake past the Indian Water Spring, then past a spring on the north side of Rosamond, then westward past Tropico to reach Willow Springs. Part of this route was traveled by members of the Pacific Railroad Survey in 1853 (Blake 1856:53-54). In 1776, Friar Garcés could not persuade his Mojave guides to provide him with a possible route to get to the Tehachapi region from the vicinity of Barstow or immediately upstream. Garcés did return to the Mojave River from the Tehachapi region by passing through the general vicinity of modern Edwards AFB (Coues 1900:I:243-244, 306). It is thus possible that some travel routes from the springs on the base, described above, may have connected with the Mojave River. Another trail from the center of Edwards AFB appears to have headed northwesterly to Desert Spring at Cantil in Fremont Valley, before heading north via Red Rock Canyon towards Indian Wells Valley. The trail from Edwards to Desert Spring was traveled southbound by William Manly Archaeological Research Design for the Antelope Valley Study Area 221 07A3822 Task Order 17 in 1849, and he described evidence of its use as a route for natives conveying stolen rancho stock to the north (Manly 1894:164-166, 236-237, 241). Conveyance Mechanisms A number of mechanisms for conveyance of goods (raw materials, finished items, and perishable items including food) were used by native groups in Southern California and the Antelope Valley, including direct access, inter-group exchange, and specialized traders. Direct Access The first category would include long-distance conveyance through direct access. Such direct access modes of conveyance would have included, in desert areas, the possibility of accessing resources in areas that were not occupied by a particular group. Both Sutton (2016) and Eerkens (1999) have proposed that in the Mojave Desert, even in the Late Prehistoric Period, there were extensive areas that were shared in this way between different groups. No particular group would have exercised domain over the shared areas, and different groups could have directly extracted resources from these areas. The extent to which such resource areas would have been shared in the Late Prehistoric and Mission Periods depended on population levels, settlement patterns, and other factors. However, it is likely that native groups in the desert or along the desert margin may have claimed control of and granted permission for use of areas where their actual occupation was rather nominal. This was the case with Mountain Serrano clans that claimed extensive desert territories around the Mojave River in the nineteenth century (Sutton and Earle 2017). Parties from groups occupying the margins of the Mojave Desert, like the Kawaiisu of the Tehachapi region, gathered salt from desert playas that were not occupied by either group, but may have been claimed as part of their territory by one group or another. Nevertheless, it is likely that resources in such remote desert areas may have been accessed by multiple groups and conveyed under this scenario. If archaeological sites at the locations of these resources indicate the ephemeral presence of different ethnic groups, a sharing scenario would appear more likely. A second kind of direct access that has been documented ethnographically is the requesting of permission to access resources in the territory of another group, or the invitation by a host group for an ally to access resources in its territory. There is ethnographic documentation of the occupation of defined territories by named kin/community groups in south central and southern California. Kroeber (1925:617, 830-831) identified the territorial nature of local groups in both central and southern California, and subsequently available material from Strong (1929) and Harrington (1986) has added to our knowledge about territorial groups and their boundaries in southern California. Sutton and Earle (2017:13-17), for example, refer to the tracing of Serrano clan (sib) boundaries on the ground in Serrano ethnographic testimony. Similar information on clan (sib) boundaries exists for the Cahuilla, especially in the Palm Canyon area and the surrounding region (Bean et al. 1991:18, 19, 21; Patencio 1943:90). Entering the territory of another group to use its resources without permission was a serious offense (Bean and Smith 1978a:547; McCawley 1996:89). Archaeological Research Design for the Antelope Valley Study Area 222 07A3822 Task Order 17 This mechanism of access to resources with permission is known to have operated within a framework of long-term reciprocity that was also expressed in other forms of political and ritual reciprocity between allied groups. Marriage ties between groups helped to structure this reciprocity. In the case of the Serrano, a specific allied clan (sib) of opposite moiety affiliation assisted a host clan in performing the rites that made up the mourning ceremony (Strong 1929:32). For the Mountain and Pass Cahuilla, Strong (1929:122-130, 180-181) describes the ceremonial participation of visiting clans in the mourning ceremony. This included reciprocal ritual exchanges of special strands of shell beads that linked the Cahuilla and Serrano with the Gabrielino/Tongva (Strong 1929). McCawley (1996:112-114) has discussed similar ritual-political institutions for the Gabrielino/Tongva, and he referred to them as “ritual congregations” - allied communities that assisted with each other's mourning ceremonies and other religious fiestas. These ceremonial gatherings of multiple communities provided a venue for the exchange of food, craft goods, and special strings of shell beads. Archaeologists have focused on the study of feasting in pre-industrial societies in recent decades. Hayden (2001:39-41) discusses the archaeology of feasting and provides a list of possible crosscultural archaeological indicators of feasting events. These include distinctive food remains, special preparation and serving vessels, special facilities for preparing or disposing of festive foods, and feasting locations or facilities. He also lists prestige items and paraphernalia associated with feasting rituals, and appropriately scaled food storage facilities, as indicators of feasting. He notes, as well, the importance of mortuary data indicating the presence in communities or social groups of political leaders. Hull et al. (2013) have identified ten sites in Ventura, Los Angeles, and Orange counties containing archaeological features related to communal mourning fiestas. They propose an innovative reconstruction of mourning fiesta cultural processes through the analysis of archaeological data from these features. They identify property disposal pits or lithic platforms associated with plaza spaces and note the recurrence at various sites of "pit clusters and secondary inhumation of selected portions of the body around a central platform cairn" (Hull et al. 2013:27). Their analysis of these and other sites aims to find archaeological indications of mourning fiesta preparations, preliminary treatment and then disposal of mourning offerings and property of the dead, and other indications of mourning processes and behaviors. An example of direct access by permission or invitation is provided by the hosting of acorn gathering by the Serrano community of Guapiabit on the upper Mojave River. For the Serrano of the upper Mojave River and an allied Desert Serrano village near Palmdale, this relationship of alliance took the form of invitations extended to various villages from the chief at Guapiabit, at the headwaters of the Mojave River, to attend a fiesta at his village where all the attending communities gathered black oak acorns in the territory of Guapiabit (Palomares 1808; Earle 2004, 2005; Sutton and Earle 2017). Such a fiesta context would involve dancing, the singing of sacred songs, and the consumption of festive foods. This acorn-gathering fiesta appears to have been at least one of the mechanisms used to convey acorns down the Mojave River, reaching at least as far as the Barstow region. In 1776 Friar Archaeological Research Design for the Antelope Valley Study Area 223 07A3822 Task Order 17 Garcés' exploration party was fed acorn porridge and greeted with the ritual gift of acorns in that area, and was also presented with acorns further upstream (Coues 1900:I:243-244). In 1826, Jedediah Smith observed imported pine nuts and acorns being consumed in the Victorville area where these plant foods are not locally available (Brooks 1977:92). Archaeological indicators of the antiquity of this conveyance include the recovery of portable mortars and pestles and acorn remains at a site north of Victorville which dated to the beginning of the Late Prehistoric Period (McCarthy and Wilke 1983:103-104). Serrano ethnographic consultants also discussed with J. P. Harrington the sharing of pinyon gathering areas between allied groups, where the owner group would hold a group fiesta for invited allied groups to gather pine nuts. The invitees provided the host with a gift of a portion of the pine nuts that they harvested (Harrington 1986:III:101:227,325). Strong (1929:33) also mentions a multicommunity rabbit hunt held in the territory of the host group sponsoring the mourning ceremony preliminary to that ceremony. Harrington (1986:101:227, 325) was also told about a kind of rabbit hunt held independently of the mourning ceremony that was hosted by a community and attended by its allies, this in the context of a fiesta that included dancing and the singing of sacred songs. Direct access to a specific resource through alliance relations may have provided a means to alleviate shortages of that resource by obtaining more of the resource from another group. In addition, communities located in different environments and resource zones would have been able to obtain from each other what they themselves did not produce. Direct access to resources in the territory of another group is presumed to have involved: • a reciprocal lending of access to the host group at a later time; • a counter-gift of a portion of the resource procured to the host group at the time of the procurement; and • provision of some other good or resource to the host group, either at the time or later. Direct procurement means that goods are procured directly from areas outside the territory of the group by the members of the group. This is different than exchange between two groups that remain in their own territories or carriage of goods by specialist long-distance traders. It is less likely that higher weight or volume or lower value goods would have been transported over long distances by specialist traders. In addition, for goods that require considerable labor in procurement and transport, direct access by a group would be an advantageous solution. Thus, for procuring acorns or pine nuts, direct access would appear to have advantages. In addition, if goods and resources are found at their place of destination in an unprocessed state, like lithic raw materials, this would appear to make it less likely that these items had been conveyed by community to community longdistance exchange or by specialist long-distance traders. Gilreath and Hildebrandt (2011), for example, note a shift at the Coso Volcanic Field away from local workshop lithic reduction by the Late Prehistoric Period, raising the possibility of direct access of lithic raw materials by outside groups. Archaeological Research Design for the Antelope Valley Study Area 224 07A3822 Task Order 17 The identification of possible direct access and procurement in the archaeological record may be related to the following factors: • recovery of goods or resources that appear to be of non-local origin; • evidence of quantities of relatively high-weight or low-value goods, like foodstuffs, having been conveyed; and • evidence for procurement and processing of goods by their ultimate users. Exchange Between Groups Through Marriage Ties Moratto (2011:245) emphasized the importance of the role of females in the conveyance of goods. In southern California, this had to do in part with marriages between exogamous clan (sib) communities that resulted in inter-group linkages through marriages with women from outside the community. Among Takic-language groups, a female moved to the clan (sib) community of her husband upon marriage. This practice is attested ethnographically and was also recorded at Mission San Gabriel (Earle 2004:181-183; Kroeber 1925:617). This created the link for movement of female-produced or utilized goods like basketry between communities. In addition, among the Cahuilla, these affinal links were activated by hunting rules that specified that unmarried hunters would provide game meat to the family and clan group of their in-married mothers (Strong 1929:77-78). Once married, a man was obliged to alternate in providing game meat to his own clan and to the clan of his wife. Marriage ties also commonly occurred between different ethnic/language groups. It was common for clan communities located in the boundary regions between ethnic/language groups to be rather multi-ethnic and multi-lingual. This is evident in mission register information on personal names for these communities (Huntington Library 2006). Archaeological inferences about inter-ethnic marriage ties would depend in part on identifying the presence of ethnically distinctive items made by in-marrying females or brought by them from their area of origin. Basketry would be the most obvious material culture marker of ethnic origin of inmarrying females. Thus, for example, the presence of three-rod willow foundation and willow sewing-strand basketry in Serrano or Cahuilla communities in historic times could be, and often was, an indicator of in-marriage by Chemehuevi females (Earle 2010a). However, the archaeological recovery of basketry is limited to caves and shelters, pack rat middens, and rare cases of carbonized basketry from mortuary contexts. It is also possible that if ceramics could be identified as to specific localities of production (clay sources), within the Mojave Desert, for example, movement of ceramics between particular places might be associated with marriage ties linking these places. Conveyance Through Specialist Traders Another major possible modality of conveyance in southern California is that of long-distance trading specialists. The concept of specialization is used here to indicate long-distance travel by individuals carrying goods to and from pre-established remote destinations, interacting with preexisting trade partners, and following pre-existing networks that included intermediate hosts. Earle Archaeological Research Design for the Antelope Valley Study Area 225 07A3822 Task Order 17 (2005) has described long-distance exchange carried out by parties of Mojave traders who traveled from the Colorado River to the southern San Joaquin Valley or the Pacific Coast in the vicinity of Santa Barbara and Ventura. They exchanged goods brought from the Colorado River region for shell beads, and sometimes other items, such as Apocynum sp. (Indian hemp) textiles obtained in the southern San Joaquin Valley. They formed part of a network of conveyance that linked the Pacific Coast and the Colorado River with Pueblo groups of northeastern Arizona and New Mexico. Other traders of this kind carried goods from the western Pueblos to the Colorado River. Friar Francisco Garcés was told in 1776 that these latter long-distance traders operated under a safe conduct arrangement (Bolton 1930:381-382). Mojave traders appear to have stayed at known host villages during their travels, as indicated by Fr. Garcés (Coues 1900; Earle 2005). Arkush (1993) has argued that the Southern Valley Yokuts carried out the conveyance of goods through use of such specialist traders. This is also suggested by information collected by Frank Latta (1999:305-312) from Southern Valley Yokuts consultants. The latter had older relatives who had been long-distance traders, and they indicated that this activity had been a family specialty. Yowlumne Yokuts territory around modern Bakersfield had been a hub of such long-distance trade, as indicated by Friar Zalvidea in 1806 and other sources (Cook 1960). Latta was told that trails from Yowlumne territory led across the Tehachapi Mountains into the Antelope Valley and also via both Walker Basin and the South Fork of the Kern River to reach the Coso obsidian source. These traders carried loads of approximately 50 pounds. Thus a 50-pound load of deer hides would be carried across the southern Sierra to reach the Mojave Desert to exchange for obsidian, and on the return trip a 50pound load of obsidian would be carried. An important characteristic of this system of conveyance mentioned by the Yokuts consultants was the trader's use of standard commodity units or bundles (Latta 1999:306-307, 309). Thus, pigments or deer hides, for example, were made into standard-sized units for conveyance and exchange. Therefore, the archaeological recovery of such standard units, such as pigment balls, would suggest such long-distance trader activity. This could include standard-sized woven fiber containers to carry items such as carrizo grass sugar or salt. Conveyance of Subsistence Items This section discusses research strategies regarding identification of possible conveyance of subsistence resources between communities in the Antelope Valley region, as well as into the region from elsewhere. It focuses on conditions that prevailed after the shift from a mobile foraging adaptation to a more sedentary settlement system with food storage and longer-distance conveyance of food resources between groups. This shift is presumed to have been under way by the Gypsum Period (see the Settlement Systems Theme). For village groups occupying local territories in the Antelope Valley, identifying the movement of food resources within or between local group territories will help define the importance of local inter-group food conveyance. This issue is relevant to the local procurement of acorns, islay (hollyleafed cherry), and mesquite beans, for example. As discussed in the section dealing with Settlement Archaeological Research Design for the Antelope Valley Study Area 226 07A3822 Task Order 17 Systems Theme known village sites in the Antelope Valley in the Protohistoric Period were located in the desert margin at the base of the mountain foothills and the desert floor on the northwest and south sides of the Valley. At least two additional places were located at springs on the desert floor (Lovejoy Springs and Buckhorn Spring) that were or may have been village sites. With respect to the conveyance of subsistence resources used at specific sites, it is important to identify whether such resources were obtained locally and directly by those inhabiting the sites or were obtained from other groups. The second case, the conveyance of resources from other groups, as noted above, may have taken the form of procurement from the territory of another (allied) group with permission or receipt of the food resources from the hands of the group of origin of the resources, or from an intermediary. The distinction, of course, has to do with which group was collecting the resource on the landscape. In the case of the movement of acorns and pine nuts down the Mojave River, alluded to above, it is known that downriver groups did gather acorns in the groves of a river headwaters group in the mountains. Food resources may also have been moved ‘down the line’ through exchange between groups along the length of the river. A number of sources of inference are available for assessing the occurrence of inter-group food conveyance through one or the other of the above modes. In the first place, as described in the Subsistence Theme section, archaeological indicators of food processing and food use at a habitation site are derived from identifying types of processing tools, performing tool use wear and residue analysis, studying macrobotanical remains, and carrying out microbotanical analyses. This will indicate what was processed and consumed at a particular period of time in the past. Second, identifying localities where collecting and field processing activities may have taken place may provide indications about who performed the collecting and processing, and the degree of transformation of the items being processed, contributing to its greater or lesser portability. In addition, identifying the locations of possible village sites, temporary camps, and procurement and processing localities can contribute to the reconstruction of a temporally-relevant cultural landscape. An element of this reconstruction is an attempt to determine, for major settlement loci, equivalent to the winter village in Late Prehistoric and Mission Periods, the areal extent and environmental characteristics of the territory and resources habitually used by such a settlement. For the Mission Period, ethnohistorical data and inferences about community population size, resources exploited, and marriage and other alliance ties can help orient this reconstruction of group territory and cultural landscapes. It is emphasized that even approximate estimates of community population size, based on both archaeological and ethnographic inference, can be very helpful to this reconstruction (Earle 2004). An important question to consider is the possible presence of 'exogenous' or foreign-origin subsistence resources within given settlements or inferred community groups. However, given that a group’s territory likely included multiple habitats and rsource zones, it may not have been necessary to obtain foreign-origin subsistence resources. Inferences from ethnohistorical and ethnographic information for the Protohistoric Period in the Antelope Valley region indicates that local winter- Archaeological Research Design for the Antelope Valley Study Area 227 07A3822 Task Order 17 village based groups occupied defined and bounded local territories. Based on the location of ethnohistorically known settlements, these territories appear to have often encompassed areas of both upland and valley floor resources that were adjacent to these settlements. Thus, upland and foothill food resources such as canyon live oak (Quercus chrysolepis) and other oak species, yucca, holly-leafed cherry, and juniper berries, along with desert margin annual small seed resources (chia, atriplex, and wild buckwheat, for example) provided a floral resource base supplemented by desert floor hard seeds, Joshua tree blossoms, and mesquite pods and beans (in the center of the valley). If all these subsistence items occurred in a group’s territory, there may have been little need to obtain resources from outside the territory unless there was a shortage of a particular resource within the territory. It can be questioned how far into the past such a territorial settlement model can be projected. Two important archaeological indices of stability over time in practices of territorial occupation would be a) long-term continuity of occupation of a core settlement, and b) long-term continuity of the archaeological characteristics of satellite camps and procurement locations (Garfinkel 2007). In addition, Sutton (2017) has raised the question, for the Antelope Valley, of whether resource zones such as the mesquite woodland found in the center of the valley may have been shared among different groups. This follows Eerkens (1999) stressing the importance of shared resource zones in the Mojave Desert. The archaeological characteristics of procurement sites occupied roughly contemporaneously in possible 'joint use areas’ can also provide inferences about shared versus territorially claimed resource areas. Ultimately, a reconstructed layout of settlements and their territories within the Antelope Valley region should suggest when food resources may have been conveyed from one territory to another through either procurement by an allied group from outside the terrritory which then conveyed the resource back to their own territory, or through conveyance or exchange between groups. Thus, if a village site at the southwest margin of the Antelope Valley displays archaeological indices of processing mesquite pods and beans (which can only be obtained from areas around springs or high water table areas), a relatively long distance conveyance of this food by one or the other of these modalities can be suspected. A major case of movement of foodstuffs, at least during the Late Prehistoric Period, is the conveyance of acorns to habitation sites on the floor of the Antelope Valley. Whether this was mostly carried out by desert margin communities provisioning their own camps on the desert floor, or whether independent desert floor settlements obtained acorns through alliances with desert margin settlements, is not completely clear. A permanent desert floor settlement existed at Lovejoy Butte (CA-LAN-192) and others may have existed at Buckhorn Spring on Edwards AFB, and at Tropico, west of Rosamond. Archaeological Research Design for the Antelope Valley Study Area 228 07A3822 Task Order 17 Research Questions and Data Needs Lithics and Minerals Conveyance and Exchange Sections in this research design on the themes of ‘Lithic Technology’ and ‘Lithic Material Sources for Flaked Stone Tools and Other Artifacts’ contain questions and data requirements on changes in availability of both local and imported lithic materials that are relevant to the theme of conveyance of lithic materials. In addition, the following questions (and embedded data needs) also refer to specific topics within this broader theme. Obsidian and Steatite 1) Is there evidence, for sites in various localities within the Antelope Valley, of importation of obsidian from sources other than the Coso volcanic field? So far, only obsidian from the Coso source has been found in Antelope Valley sites. However, it is possible that obsidian from other sources was used. Determing whether other sources of obsidian were used would depend on chemical sourcing of obsidian samples, as is discussed in the section on the theme of ‘Lithic Material Sources for Flaked Stone Tools and Other Artifacts’. This would clarify the extent of dominance of the Coso volcanic field as an obsidian source in various localities of the Antelope Valley. 2) What are the chronologies for production of steatite bowls, as indicated by presence in Antelope Valley sites? Are there indications of export of stone bowls throughout the Antelope Valley or to other regions? Answering these questions would require the dating of the occurrence of these classes of lithic artifacts in Antelope Valley sites and determining the source of schist and steatite (using petrographic sourcing) and obsidian (using chemical sourcing) artifacts found in Antelope Valley sites. Asphaltum Conveyance and Exchange 3) Can asphaltum-treated objects (such as basketry and tarring pebbles) or raw asphaltum found in archaeological contexts in the Antelope Valley be chemically sourced to indicate region of origin? Is asphaltum found in standard-sized lumps or balls indicating conveyance by specialist long-distance traders? Principal sources of asphaltum in southern California include the Ventura-Santa Barbara coast and the McKittrick region of western Kern County. The extent to which the Kern County sources, as opposed to coastal sources, were used in different areas of the Antelope Valley is currently unknown. Chemical sourcing of asphaltum (Brown et al. 2014) from datable archaeological contexts in the Antelope Valley would help to answer these questions. Archaeological Research Design for the Antelope Valley Study Area 229 07A3822 Task Order 17 Pigments Conveyance and Exchange 4) Can a differential spatial distribution of either ochre or manganese pigments in lump form, pigments that appear to have been conveyed from distant sources, be identified in Antelope Valley sites? The discussion of pigments indicated that red ochre was obtained in the Tejon Ranchería area of the southern San Joaquin Valley and carried by the Mojave from the Colorado River region. Evidence of differences in the frequency of recovery of these pigments in different areas of the Antelope Valley might indicate paths of conveyance and exchange of these pigments. Identification of ochre or other mineral pigments in lump form would also be needed. 5) Is there evidence of an increase in importation and use of ochre or other pigments over time? The use of these pigments was especially important because of the cultural and ritual significance of body painting. This means that the obtaining of these pigments was necessary on a constant basis. Indications of the frequency of lump ochre in different archaeological strata could provide an index of intensity of importation and use during different prehistoric time periods. The presence of quantities of ochre might be considered one indicator of winter village ceremonial activity, for instance. To answer this question, recovery of ochre or other mineral pigments in stratified and dated archaeological contexts would be necessary. Shell Bead Conveyance and Exchange 6) What changes can be observed over time in the quantities of different types of beads and other shell ornaments being imported into the region? The discussion above has referred to a general pattern of long-distance conveyance or exchange of spire-ground Olivella, Olivella barrel, or whole Olivella shell beads from the southern California coast to the Antelope Valley prior to the Gypsum Period. During the Gypsum Period, Olivella saucer and wall beads become more common. The analysis of such shifts in the quantities of specific types of beads being exchanged into the region may reflect changes in types being fabricated (Arnold and Graesch 2001) and/or changes in demand at destination locations. Stylistic chronologies for the fabrication of Olivella and other shell beads have long been available and have been successively refined. In recent years, sophisticated application of AMS radiometric dating to shell samples has allowed cross-checking of these chronologies (Groza 2002; Milliken and Schwitalla 2012). The chronologies provide a means of developing analyses of temporal shifts in the intensity of utilization of specific bead types at archaeological sites of destination. This research problem permits the profiling of the emergence and maintenance of long distance conveyance and exchange systems for shell beads. A general trend of increase in rates of conveyance over time might be predicted, but variations in this rate would provide insights into the development of such long-distance movement of shell beads. 7) Given information available for the areas of fabrication regarding changes in bead types and styles over time at the localities of origin (Arnold and Graesch 2001; Milliken and Schwitalla 2012), are there Archaeological Research Design for the Antelope Valley Study Area 230 07A3822 Task Order 17 any apparent shifts in frequency for different kinds of beads in local archaeological sites that could be plausibly related to changes in the functions of specific types of beads? Change in the rates of fabrication of specific types of beads, for example on the Channel Islands, reflects changes in fabrication technology and, presumably, changes in demand for specific types of beads over time. For the Antelope Valley region, there may be changes in how shell beads are used in other words, changes in demand for specific kinds of beads. A shift from the use of spire-ground whole Olivellas to tiny saucer Olivella beads during the Gypsum Period would represent this kind of shift. It could be hypothesized that over time, functional specialization of specific types of beads - as objects of personal adornment, as objects of ceremonial prestation and counter-prestation, as mortuary goods, as objects destined for routine economic exchange, and as objects used for longterm storage of value - would tend to increase. The history of such developing specialization at the local level may be reflected in the local archaeological record. 8) What changes can be observed over time in the identifiable sources of different types of beads being imported into the region? For the Antelope Valley region, the Channel Islands and coastal southern California provide the principal source of Olivella, clamshell, Mytilus, and other shell beads and ornaments. The Gulf of California is also a possible source of Olivella dama beads. Importation of Olivella shell beads across the deserts from the Gulf of California would be important to document as an element of Mojave/Colorado Desert long-distance conveyance (Dahdul 2011). 9) Is there evidence that Antelope Valley sites participated in long-distance conveyance of coastal shell beads into the Great Basin or the Colorado River and the Southwest during various periods in the past? Antelope Valley native communities are known to have participated in such long-distance conveyance during the protohistoric period. Specifically, members of trading/traveling parties from the direction of the Colorado River, especially groups of young Mojave men, engaged in a trek taking approximately 15 days one way from the Colorado River to the southern California coast, and 10 days to the southern San Joaquin Valley (Earle 2005). Chemehuevis are also reported to have engaged in this kind of long-distance exchange. Such traders were dependent on the hospitality of host villages along the way. The amassing of bead wealth by Serrano-speaking chiefs along the Mojave River suggests that they benefited materially from their roles as hosts (Earle 2005:8). Identification of a similar pattern during earlier periods would involve several research strategies: first, the identification of an unusual abundance of specific types of beads that were being exchanged on the long-distance basis; and second, a comparison with other regions in Southern California in respect to different measures of general abundance of beads of different types at various time periods in habitation sites. In addition, it is possible that the presence of exotic items originating in the Colorado River region or the Southwest might provide an indication of such longdistance travel and exchange. Southwestern ceramics are known to have been imported into southern California from the Southwest, along with in exchange for shell beads (Earle 2005:13,15,32; Archaeological Research Design for the Antelope Valley Study Area 231 07A3822 Task Order 17 Ruby 1970). This type of exchange obviously has different social characteristics from an alternative type of 'down-the-line' exchange system where quantities of beads gradually move from hand to hand. 10) Are there variations within the Antelope Valley in the relative frequency of use of Olivella as opposed to clamshell beads? It is possible that the relative frequency of these two types of beads might contribute to distinguishing between populations based in the southern Sierras, Including the Tehachapi Mountains, and the south side of the Antelope Valley. Clamshell beads enjoyed some popularity among native people in the southern San Joaquin Valley and in the southern Sierras (Voegelin 19381940:50). This may have extended to the northern margins of the Antelope Valley. Shell beads from dated contexts identified using standard bead typologies. Beads should be measured to aid in identification. Stone Beads and Ornaments Conveyance and Exchange 11) What is the chronology for first appearance and later use of stone beads in the Antelope Valley? Can time periods be identified when these types of beads are particularly abundant? a) Are there differences in frequency of stone beads at sites in different areas within the Antelope Valley? b) What lithic raw materials were being used for fabrication of stone beads found at sites in the Antelope Valley? c) Is there archaeological evidence for stone bead manufacture at sites within the Antelope Valley? d) Chester King (1990) has suggested an association or co-occurrence of certain kinds of shell beads and stone beads in the Santa Barbara Channel region and hypothesized that the two types of beads were used together to make up bead strings. Is there evidence for a similar functional co-occurrence in the Antelope Valley? e) Is there evidence for the conveyance of stone beads from the Antelope Valley to other regions? To answer these questions, stone beads and pendants should be classified by material type and form. Chronological questions can be addressed if stone beads are recovered from dated stratigraphic contexts during site excavation in the Antelope Valley. Access to stone bead and ornament collections from areas outside of the Antelope Valley would be needed to answer questions about export of these artifacts from the Antelope Valley. In addition, identification of the chemical and physical characteristics of local stone sources (schist, for example) would be needed for identification of exported specimens. Archaeological Research Design for the Antelope Valley Study Area 232 07A3822 Task Order 17 Glass Beads Conveyance and Exchange 12) What does the possible presence, abundance, and chronological placement of glass beads as a temporal marker at sites in the Antelope Valley suggest about the chronology of occupation of these sites? a) What do both the possible presence of glass beads at sites in the Antelope Valley and their type suggest about the timing and intensity of Spanish or other European contact with native communities in the area? b) Does the possible presence of certain temporally late types of glass beads at archaeological sites in and around the perimeter of the Antelope Valley suggest that certain sites were occupied at late dates during the nineteenth century? Glass beads classified by form, color, and size. Chronological questions can be addressed if stone beads are recovered from dated stratigraphic contexts during site excavation in the Antelope Valley. Ceramics Conveyance and Exchange 13) What is the spatial and temporal distribution of specific types of ceramics within the Antelope Valley? In analyzing site collections in the Antelope Valley, it is assumed that ceramic materials will be scarce, especially in the southwestern part of the valley, and will be of Late Prehistoric date. Those assumptions need to be continually tested, particularly in respect to the appearance of ceramics of a Southwestern style at earlier dates. The question of distribution is related to the problem of identifying imported as opposed to locally made wares, as is discussed below. 14) Through analysis of ceramic technique and style, and through petrographic analysis of constituent clays, what exogenous localities of origin can be identified for ceramic materials found in the Antelope Valley region, possibly including Desert Cahuilla or Lower Colorado River sources? Scarce presence of ceramic materials at sites in the region has provoked the question of exotic origin. It is noted that ceramic materials appear to be more abundant in the eastern as opposed to the western Antelope Valley. It is known that the Desert Serrano of the Mojave River used ceramics during Late Prehistoric times. It is also assumed that some ceramics were locally fabricated by the Serrano, although ethnographic accounts or collections documenting this are unfortunately lacking. For the Desert Cahuilla, southeastern neighbors of the Serrano, ceramic production in Late Prehistoric and historic times is well attested, and workshop samples were collected from potters in the nineteenth century (Schumacher 1880). The Cahuilla wares reflected some similarities with those produced on the lower Colorado River by Yuman-speaking groups such as the Mojave and Quechan in Late Prehistoric times. Researchers interested in the cultural history of the Mojave Desert, such as Claude Warren (1984), have attempted to identify the timing and distribution of lower Colorado River origin ceramics as far west as the Antelope Valley (the Patayan influence). A concern driving this interest is the scenario of a possible occupation of the lower Mojave River and desert areas to the east by the so-called Desert Mojaves in Late Prehistoric times. Such an occupation may have been Archaeological Research Design for the Antelope Valley Study Area 233 07A3822 Task Order 17 reflected by the movement of lower Colorado River ceramics up the Mojave River and across the western Mojave Desert. 15) Where in the Antelope Valley region can Numic-style ceramics, brownwares and graywares, be found, and what dates can be assigned to these? Can these be identified petrographically as imported or locally made? This category of ceramics is found in late prehistoric contexts, especially on the north side of the valley. It would appear to have some utility as an ethnic marker for the presence of Numic-speaking groups. The archaeology and ethnohistory of Numic ceramic production in the southern Sierra region during the late prehistoric period has recently received research attention (Garfinkel 2007; Moratto 2011). 16) Can ceramic types stylistically linked to areas of production elsewhere in Southern California or to the east (Tizon brownwares or the Lower Colorado River wares) be identified as actually locally made? Suzanne Griset has discussed petrographic analysis aimed at differentiating between imported ceramics and items of similar style that were, in fact, locally made (Intermediate Desert Wares). This has been based on comparison of the characteristics of clays that were used. Of particular interest here would be the identification of ceramic craft specialization in the western Mojave Desert. Griset's identification of locally made, or relatively locally made, ceramics at Lovejoy Springs (CA-LAN-192) raises the question as to whether there were Serrano ceramics producers, on the upper Mojave River, for example, who may have been involved in producing relatively locally made ceramics. 17) Do we have evidence of the exchange or transport of Anasazi or other Southwestern ceramics into the Antelope Valley? As previously discussed, Anasazi or other Southwestern ceramic sherds have been found at sites in the Antelope Valley, for example, on Edwards AFB, at CA-LAN-192, and apparently at Barrel Springs (CA-LAN-82). Apparent Anasazi use of a turquoise mine at Halloran Springs, to the east of the Sinks of the Mojave River, indicates their presence in the central Mojave Desert region. This has pointed to the significance of Anasazi ceramics at Antelope Valley sites as possible indicators of exchange with Anasazi present in the Mojave Desert. Identification and analysis of ceramics from sites in the Antelope Valley. Recovery of ceramics from dated stratigraphic contexts will assist with chronological questions. Classification should be based on style, form and function, and analysis of ware and temper. Petrographic analysis will assist with questions about the source of clays used to make ceramics. Direct Access to Resources 18) What archaeological evidence exists in Antelope Valley sites for direct access to distant resources by inhabitants of these sites? Archaeological Research Design for the Antelope Valley Study Area 234 07A3822 Task Order 17 Evidence of direct access involves identifying non-local resources that may have been conveyed to Antelope Valley sites by this means. Direct access to resources can be seen as an efficient means of obtaining items of lower unit value, higher unit weight, or requiring higher investment in procurement or processing skills and labor. It is an extension of the fundamental family labor strategy of local collecting to more distant resources, rather than a procurement specialist strategy. The conveyance of high weight or volume resources, like food products, from distant places of origin implies a semi-sedentary settlement and social regime, such that distant bulk resources are carried to where groups reside (logistical mobility), rather than such groups moving to the resources (residential mobility). It also implies a ramping up of the intensity of application of family labor to meeting subsistence needs. This is presumably associated with population growth and consequent intensification of resource exploitation. Archaeological indicators of direct access in resource procurement may include evidence of use of craft or food resources that a) are of non-local-community origin (e.g., obsidian, acorns, pinyon pine nuts), b) are consumed on a large scale (like acorns), and c) are more effectively procured and conveyed through family labor rather than specialist labor. 19) Are conveyance items (e.g., acorns, lithic raw materials, etc.) found archaeologically at the point of destination in the Antelope Valley in the unprocessed state? These are possible indicators of direct access. Do we find evidence of such items or products at sites in the Antelope Valley region? Large amounts of craft or food resources of non-local origin (from outside the local community) that could be conveyed to the residential base through family labor. Some of the food items may be in an unprocessed state (back-loaded resources as described in the Subsistence section). Inter-Group Marriage and Exchange 20) Can we find archaeological evidence of inter-group exchange based on marriage ties? Such exchange may have linked both nearby and more distant communities in and outside the Antelope Valley. Such exchange may be difficult to distinguish from direct access with permission except that it might involve smaller quantities of goods or products and sometimes goods of higher value or of greater prestige. Non-local goods found at a particular habitation site originating in the habitat of an adjacent or nearby community might indicate exchange and social ties involving marriage links. In addition, inter-ethnic marriage links may be more visible in the archaeological record, due to the presence of artifacts and implements in sites of residence of in-marrying women that have ethnically different characteristics. Non-local goods found at a particular habitation site originating in the habitat of an adjacent or nearby community. Artifacts and implements in sites of residence of in-marrying women that have characteristics that are ethnically different from the site where the artifacts were found. Social Contexts of Direct Access with Permission and Inter-Group Exchange 21) Is there evidence in Antelope Valley archaeological sites for ritual mourning practices indicating ritual congregations of allied groups where direct access with permission may have taken place? Archaeological Research Design for the Antelope Valley Study Area 235 07A3822 Task Order 17 Archaeological indicators of feasting and ritual mourning behavior residential bases and villages, according to Gamble (2008), Hull et al. (2013), and Hayden (2001), may include: a) ritual plaza areas used for mourning ceremonies, including fire pits or platforms b) evidence of ritual destruction of property, perhaps through burning and subsequent pit burial c) shell beads that may be high-value or prestige items of non-local origin (possibly indicative of inter-group ritual exchange) recovered in the context of apparent mourning ceremonies or ritual destruction of property d) special steatite or other cooking vessels that may have been used in food preparation associated with ritual feasting Artifacts and features from excavation of residential bases or villages that have the characteristics of indicators of feasting and ritual mourning behavior (as indicated above). Conveyance by Long Distance Traders 22) What archaeological evidence exists for conveyance of goods by long-distance traders? Long-distance conveyance by traders is a specialist activity, involving higher-value items being conveyed. These may have been conveyed in units of standardized size and/or value. They also may have taken the form of 'finished goods’ that display already processed conventional characteristics, like asphaltum balls, finished obsidian bifaces, or shell beads. It is not expected that long-distance traders would have frequently conveyed lower-value bulk items like subsistence products. Items conveyed by long-distance traders would have the following characteristics: a) items of non-local origin; b) items with a standardized unit size or value; and c) items with the characteristics of 'finished objects' of relatively high value. 23) Does the possible geographical distribution of non-local high-value items that may have been conveyed by long distance traders at sites in the greater Antelope Valley region shed light on the spatial patterns and routes of conveyance that may have existed? Items from excavation of residential bases or villages that have the characteristics of goods conveyed by long-distance traders (as indicated above) and their spatial distribution. Local Conveyance of Subsistence Items As previously noted, local or intergroup conveyance of subsistence resources is archaeologically detectable where there is evidence of use of subsistence items that were obtained from outside the immediate territory of the local group. Either subsistence remains or residues themselves are detectable (see the Subsistence Theme section) or associated food processing or preparation implements are recovered for such subsistence items that can be inferred to be exogenous to a local community or group. Archaeological Research Design for the Antelope Valley Study Area 236 07A3822 Task Order 17 24) What archaeological evidence exists for inter-community or other local conveyance of specific subsistence resources, such as acorns or mesquite beans, for example? Answering this question involves identifying the presence of subsistence resources not obtainable within the territory of the local community. 25) What archaeological evidence exists for local processing of subsistence items imported from outside the local community? Based on the available archaeological evidence, what inferences can be made regarding relative quantities of imported and local subsistence resources being used, and about possible changes in these relative amounts over time? Evidence needed to answer these questions would include both the state of food remains and the presence of food-processing tools and implements. Such local processing may indicate direct procurement rather than conveyance through inter-community exchange. 26) Do changes in the relative importance of subsistence resources conveyed into local communities, such as acorns, for example, correlate with archaeological indicators of population increase over time? These indicators might include numbers of sites occupied or increases in artifact density or site size at habitation sites characterized by long term occupation. Subsistence remains (animal bone and macrobotanical remains) or residues on food processing tools, and the food processing tools themselves is also required to answer this question as well as others presented above. Archaeological Research Design for the Antelope Valley Study Area 237 07A3822 Task Order 17 Theme: Lithic Technology The culture history and chronology of the Mojave Desert and the rest of the Great Basin relies heavily on changes in projectile point style and inferred technological change (Coombs 1979; Stickel et al. 1980; Sutton 1996, 2016, 2017; Sutton et al. 2007; Wallace 1962; Warren 1984). While projectile points figure prominently in any attempt to examine culture history in the Great Basin, other forms of flaked stone tools provide key components as well. These include bifaces, unifaces, retouched flake tools, utilized flakes, and unmodified debitage including both flakes and shatter. The first section of this theme review describes each of these artifact categories, as well as relevant analytical approaches. The second section synthesizes the current understanding of how lithic technology varied over time in the Mojave Desert, and in the Antelope Valley in particular. Flaked Stone Tools and Debitage in the Western Mojave Desert Projectile Points Projectile points are commonly used as diagnostic artifacts in all regions of the Great Basin, with a consistent morphological classification system (Bettinger et al. 1991; Bettinger and Eerkens 1999; Flenniken and Wilke 1989; Messoudi and O’Brien 2008; Simms 2008; Sutton 1996; Sutton et al. 2007; Wallace 1962; Warren 1984). Attributes of projectile point morphological and stylistic composition lend themselves readily to analysis. Such characteristics as size, material, weight, stem treatment, hafting position, and shoulder angle are common variables examined in projectile point analyses. Projectile points are nearly universally viewed as key parts of weapons systems instrumental in hunting and sometimes conflict. Recent interpretations of projectile point technology have begun to also consider how these artifacts can reveal social reproduction and technological transmission (Bettinger 2015; Bettinger and Eerkens 1999, Bettinger et al. 1991; Flenniken and Wilke 1989; Walsh 2011), as well as climatic adaptation (Sutton et al. 2007; Sutton et. al 2010). Such approaches examine morphological change in variables such as projectile mass and length through time (Mesoudi and O’Brien 2008). Bifaces Bifaces were used by nearly all stone-tool using societies. Andrefsky (1998:172) defines bifaces as tools with “two sides that meet to form a single edge that circumscribes the entire artifact … both sides are called faces and both show evidence of previous flake removals.” Their most likely functions are cutting or chopping, but they frequently were used for multiple purposes. Bifaces often serve as cores as well. Some were hafted to a wooden or bone handle or shaft. Technically, projectile points are usually bifaces as well, but in the Great Basin projectile point styles are well known and consistent and are thus usually analyzed separately. Bifaces are often distinguished by the degree to which they Archaeological Research Design for the Antelope Valley Study Area 238 07A3822 Task Order 17 have been transformed from a core to a finished tool. This can be viewed as a continuum or as a series of stages (Andrefsky 1998:180). The stage concept is probably the most common analytical approach to bifaces among western Mojave archaeologists, with schemes of both four and five different stages of completion. Early stages (Stage I or II) on the continuum have fewer flakes removed from the edges and can have considerable cortex. Middle stage (Stage II, III, or IV) examples have been thinned significantly, with flakes removed across the center of the artifact, with some cortex possible, and nearly all edges worked. Late stage (IV or V) bifaces are considered final or nearly final products with refined flaking (usually pressure flaking) on all surfaces. Importantly, biface morphology is not diagnostic, as their forms are consistent across the long millennia of Great Basin prehistory. It is possible, however, that preferred material types or functions do change through time and or space. Unifaces Unifaces are stone tools that have only had smaller flakes removed on one side of a flake or core edge. Generally, they are thought to represent a more casual tool that is produced with less effort than bifaces. Even more so than bifaces, unifacially worked tools appear to be consistent in morphology over the entire span of prehistory in the Great Basin, though changes in material type do appear to change according to age and location. Cores Cores and core tools other than bifaces are commonly found in archaeological sites in the western Mojave, but seldom are present in large numbers. Cores are usually divided into two types: unidirectional and multidirectional. It is very rare to find cores of high quality material far from lithic sources. For example, obsidian cores are rarely found in the Mojave Desert. Debitage Debitage provides invaluable insights into stone tool technologies and economic systems (Andrefsky 1998, 2001; Sullivan and Rozen 1985). Intentionally produced flakes and pieces of angular shatter often reveal more detail about technology and economic behavior than can be recovered from finished, broken, or exhausted tools. Debitage has several inherent advantages over other classes of artifacts. First, it generally provides reliable sample sizes. This data set is also less likely to be compromised by artifact collectors. Another advantage is that debitage analysis can be performed quickly without expensive or destructive specialized analyses. Modified flakes, often referred to as expedient tools (Andrefsky 1998: 30, 213-214; Binford 1979; Parry and Kelly 1987), were likely produced for short-term use only. Debitage material can also shed light on the degree of mobility of prehistoric social groups. In general, a homogenous and local assemblage of lithic debitage suggests a high degree of sedentism, while greater mobility is likely indicated by varied resources that were imported over some distance (Parry and Kelly 1987). Debitage material can thus reveal long-distance procurement and conveyance Archaeological Research Design for the Antelope Valley Study Area 239 07A3822 Task Order 17 strategies based on either direct travel to lithic sources or through exchange systems (Hughes and Milliken 2007; Hughes 2011). Effective debitage analysis requires an appropriate classification system that will generate data relevant to research objectives. For the western Mojave Desert, important research questions include how raw material (cobbles or cores) was obtained and how raw material was transformed into desired blanks or tools. One such debitage classification system has a long history in the southern eastern Sierra and the western Mojave Desert. It was pioneered in the region in an early study of the Coso obsidian quarries by Elston and Zeier (1983, 1984), based on earlier work by Muto (1971). The typology was further developed by Allen (1986) in a study of the debitage at the Coso Junction Ranch Site (CA-INY-2284) just west of the Coso quarries. These were all attempts to distinguish stages of lithic production. Andrefsky (1998:111-114) has since categorized this approach as a triple cortex typology. Allen (1986:19) describes three stages of biface tool production: “first, the creation of a regular edge on a blank to permit controlled thinning; second, controlled longitudinal thinning; and third, the creation of final elements and final edge treatment.” Typically, such a stage concept distinguishes the production of primary, secondary, and tertiary flakes corresponding to three production stages. Primary flakes are large flakes removed in the initial reduction of a core and the preparation of regular edges suitable for more precise flaking. Secondary reduction can include the production of two kinds of flakes: secondary flakes suitable for further modification into tools and biface thinning flakes removed to create bifaces. Tertiary reduction represents final tool production and maintenance. In a study of two western Mojave archaeological landscapes, Allen further defined this classification system: Primary flakes are defined as having less than four flake scars on the dorsal surface and containing from 50% to complete cortex on the dorsal side of the flake, as well as greater thickness compared with length. Secondary reduction flakes have more than four flake scars on the dorsal surface. Secondary flakes could contain some dorsal cortex but comprising less than half of the surface. Also, secondary flakes can have a striking platform or a bulb of percussion. Biface thinning flakes are specialized forms of secondary flakes that are struck when producing bifacial tools. These flakes are mainly recognized by the longitudinal curvature, a feathering termination, a lip, a bulb of force, and thin lateral and distal edges. As with secondary flakes, biface thinning flakes can have little or no dorsal cortex. Unlike the other flakes that are made by percussion flaking, tertiary flakes are created by pressure flaking, and are often referred to as pressure flakes. Tertiary flakes are characterized by thin, almost parallel edges, few dorsal scars, no dorsal cortex, and small size. One other type of debitage used in this typology is shatter, the incidental pieces that result from less Archaeological Research Design for the Antelope Valley Study Area 240 07A3822 Task Order 17 controlled percussion, or with poor-quality material. These are usually angular and blocky (Allen 2013:91). There are other possible approaches to debitage analysis. The technological typology “refers to a debitage typology that separates detached pieces into groups based on some characteristic(s) of stone tool technology” (Andrefsky 1998:118). Examples of technological debitage types include biface thinning flakes, retouched scraper flakes, bipolar flakes, striking platform preparation flakes, and notching flakes (Andrefsky 1998:118). Attribute approaches seek to minimize analytical bias by relying on objective measurements of flakes (Railey and Gonzalez 2015; Sullivan and Rozen 1985). Aggregate analysis of debitage is another common approach (Andrefsky 1998:126-134; Hall and Larson 2004). In this form of analysis, a debitage assemblage is stratified by an attribute criterion such as weight or size, and then each subset is analyzed in comparison to the others by relative frequency. Lithics analyses conducted as part of future archaeological investigations in the Antelope Valley should utilize the triple cortex typology system modified by Allen (2013) from earlier typologies developed for the Coso volcanic field by Elston and Zeier (1984, 1985), as these are deemed most appropriate for answering the research questions at the end of this section. Use of this typology will also permit direct comparison with previous analyses of large debitage assemblages in the western Mojave Desert. See Attachment B for an example of the application of this typology system for a lithics analysis of four archaeological sites tested during the SR-138 Northwest Corridor Improvement Project. Lithic Technology in the Western Mojave Desert through Time This section reviews the current understanding of lithic technology through time in the western Mojave Desert and, more specifically, the Antelope Valley region (see the Chronology section). Pre-Clovis Period The earliest proposed cultural period, the Pre-Clovis Period (> 12,000 cal BC), is a hypothetical one. Thus far, no archaeological site has conclusively been assigned this age anywhere in the Mojave Desert. However, since early sites that date to this period are now fairly accepted elsewhere in North America and South America, it is certainly possible that one or more sites dating to this time period in the Mojave Desert will be identified in the future. If so, we might expect tool and flake assemblages like those of Paleocoastal Tradition sites on the Channel Islands or the Pacific coast, as there is evidence supporting the model that early coastal populations with stemmed projectile points migrated eastwards into the interior to exploit pluvial lakes, the so-called Western Pluvial Lakes Tradition (Beck and Jones 2010). Paleo-Indian Period The Paleo-Indian Period or Fluted Point Complex (12,000 to 9500 BC) is represented in the region by a few isolated fluted projectile points, mostly recovered from surface contexts near Pleistocene lakes Archaeological Research Design for the Antelope Valley Study Area 241 07A3822 Task Order 17 (Glennan 1971; Sutton 1988b, 1996; Sutton et al. 2007; Warren 1984). Clovis points have been found at China Lake in the western Mojave Desert, but a lack of other associated archaeological material means that our knowledge of human activity during the late Pleistocene in the region is minimal. Surface finds of fluted projectile points are found as isolates and in sites in the western Mojave Desert, but there is not yet a firmly dated Paleo-Indian site. The potential for such a site must be considered high, however, given the presence of several large Pleistocene lakes in and near the Antelope Valley, including Koehn Lake in the Fremont Valley to the north, Harper Lake to the east, and Rosamond Lake and Rogers Lake in the central Antelope Valley. Moreover, it has been postulated that these lakes may have at times been united as Lake Thompson (Dibblee 1960, 1967; Sutton 1988b:13-14; Thompson 1929). This would have been an attractive environment for PaleoIndian populations. Fluted points are usually interpreted as effective weapons for large game, likely launched as darts with atlatl spear throwers. Lake Mojave Period It is not until the Early Holocene geological period that archaeologists have identified definite archaeological evidence of human occupation in the western Mojave Desert. The Lake Mojave Period (9500 to 7000 BC) is identified by stemmed projectile points, flaked crescents, bifaces, and limited amounts of ground stone and cobble-core flaked stone tools. Lake Mojave and Silver Lake are two common types of stemmed points from this period, often categorized as part of the Great Basin stemmed series associated with the Western Pluvial Lakes Tradition found across the Great Basin (Warren 1984). Most archaeologists agree that this period had small populations of mobile foragers who moved throughout large ranges and had social networks across large areas, as indicated by shell beads and lithics found far from their point of origin (Beck and Jones 2010, 2011). Many sites dating to this period have been found around the playas of former Pleistocene and Early Holocene lakes, such as those on the Fort Irwin and China Lake Naval Air Weapons Station military installations, but with additional examples at Lake Mojave in the eastern Mojave, Twenty-Nine Palms, and Rosamond Lake in the Antelope Valley (Sutton et al. 2007:234-238). The stemmed points of the Lake Mojave Period lack regular edges or symmetry, have weak shoulders, and usually exhibit large flake scars. They were likely used as dart or spear points launched with atlatls, and were frequently resharpened, often resulting in short lengths at the end of their utility. In contrast to Late Holocene periods, a high percentage of flaked stone artifacts of the Lake Mojave Period are basalt or rhyolite rather than cryptocrystalline silica (e.g., chert, chalcedony, jasper, quartzite) or obsidian. The selection of less glasslike material suggests a preference for durability and long-term tool curation, congruent with high degrees of mobility (Sutton et al. 2007:237-238). Crescents represent an unusual tool type often interpreted as functioning in aquatic environments since they are commonly found along Late Pleistocene or Early Holocene shorelines. Lake Mojave flaked stone tool assemblages are usually interpreted as large-game hunting and butchering technology, but this is at odds with existing faunal profiles and protein residue analyses that indicate small or medium-sized animals were most frequently hunted. Interestingly, while projectile points are Archaeological Research Design for the Antelope Valley Study Area 242 07A3822 Task Order 17 often made of strong materials like basalt and rhyolite, unifacial tools, such as scrapers, that could have been used for butchering, were commonly made from cryptocrystalline materials. Pinto Period The lithic technology of the Pinto Period (8250 to 2500 BC) appears to overlap temporally with the Lake Mojave Period, and quite a few archaeological sites have evidence of both types of diagnostic artifacts. While Pinto sites first appear during the Early Holocene, the majority date to the MidHolocene. Pinto sites are much more common than Lake Mojave sites in the Mojave Desert (especially the central Mojave Desert) and they are found in a wide range of settings, including both lakeshores and uplands. The use of higher elevations is likely one response to increasing aridity and desiccation in the Middle Holocene. The biggest technological change seems to be increased use of ground stone tools, presumably reflecting a greater dependence on seed processing and decreased emphasis on hunting. This might explain the crudeness of many clearly finished specimens of Pinto points that have stemmed and indented bases. They are even less symmetrical than those of the Lake Mojave Period, perhaps functioning only as tips for thrusting spears rather than as atlatl darts (Sutton et al. 2007:238). However, it is likely that atlatl technology did not completely disappear during the Pinto Period as it certainly was well established during the early Gypsum Period. Perhaps more so than in the Lake Mojave Period, preferred materials for Pinto points and other flaked stone tools were fine-grained volcanic materials such as basalt and rhyolite, suggesting the importance of tool curation and durability, as these are strong tool materials (difficult to flake, but not brittle, resulting in less breakage). Retouched flakes, however, were often cryptocrystalline materials. It has been posited that local rhyolite sources in the Antelope Valley, especially Fairmont Butte in the southern part of the Antelope Valley, were most heavily exploited during the Pinto Period (Glennan 1970, 1971; Sutton 1988b), with the possibility of an early “Rhyolite Tradition” that nearly exclusively produced stone tools out of this strong material. Glennan (1970, 1971) based his interpretations mostly on surface materials at a large quarry site (CA-LAN-898) and a nearby habitation site (CALAN-298) at Fairmont Butte, with a heavy reliance on a single obsidian hydration reading from a surface collected Pinto point. Large early-stage (i.e., Stage I or II) ovoid rhyolite bifaces from Fairmont Butte were interpreted by Glennan as crude, but complete tools from the Middle Holocene (Sutton 1982a). Subsequent work, however, has suggested that these were preform tools or blanks, and that Antelope Valley rhyolite was mostly consumed during the Late Prehistoric Period (Scharlotta 2014; Sutton 1982a). This finding, however, does not preclude the possibility of a Pinto Period (or earlier) presence in the Antelope Valley which relied heavily on local rhyolite sources (Sutton 1982a, 1988, 1993). Clearly, the Fairmont Butte sites and other rhyolite sources in the western Mojave Desert, such as Rosamond Hills in the central Antelope Valley (Sutton 1993), are important for better understanding the earlier occupations of the Antelope Valley and the rest of the western Mojave Desert and adjacent regions. Archaeological Research Design for the Antelope Valley Study Area 243 07A3822 Task Order 17 Gypsum Period Major technological changes were introduced in the Gypsum Period (2500 BC to AD 225). Significantly more effort and time were invested in production of projectile points, and cryptocrystalline silica and obsidian were much preferred over stronger basalt and rhyolite. Three styles of typically well-crafted projectile points are characteristic of the period: Gypsum series (with well-shouldered contracting stems), Elko series (with corner-notched bases), and Humboldt series (with concave bases). These projectile points likely functioned as darts thrown with atlatls. Large bifaces used both as cores and as core tools are also much more common than in preceding periods. Small Gypsum Period sites are extremely common, ranging throughout the Great Basin. In the Mojave Desert, they are found far more often in the western and northern parts of the Mojave Desert, than in the eastern or southern areas of the Desert. The presence of sites in higher elevations, investment in well-made pressure-flaked projectile points, extensive use of bifaces, and the ubiquity of artiodactyl faunal remains during the Gypsum Period all indicate increased reliance on large-game hunting (Allen 2013; Hildebrandt and McGuire 2002; Sutton et al. 2007:241). This likely explains why sites from the Gypsum Period are more common in the western and northern areas of the Mojave Desert, as higher mountain ranges with better artiodactyl habitat are found in these areas. During the Gypsum Period there was an increased reliance on obsidian for projectile points and bifaces. Extensive research at and near the Coso obsidian quarries (Allen 1986; Elston and Zeier 1983, 1984; Gilreath and Hildebrandt 1997, 2011; Yohe 1992, 1998) shows that obsidian production for tool-making and trade increased dramatically during the Gypsum Period. In the western and northern Mojave Desert, several large residential bases or villages were established along the easiest line of travel from north to south along the eastern edge of the southern Sierra Nevada through the western Mojave Desert, sometimes referred to as the “Obsidian Highway.” The most important export product from this area during the Gypsum Period was obsidian biface preforms (Stage I or II bifaces). These were produced mostly at habitation sites in the region for exchange with groups in the Sierra Nevada, the Central Valley, and Southern California. Posited nodes in this production and exchange system include the Rose Spring Site (CA-INY-372) (Lanning 1963; Yohe 1992, 1998), the Coso Junction Ranch Site (CA-INY-2284) (Allen 1986), a large site on Koehn Lake (CA-KER-875) in Fremont Valley (Sutton 1991), and several large sites in the Antelope Valley (Sutton 1988b:74-76). These sites seem to reflect village-like sites situated to take advantage of the social and economic opportunities afforded by the growing importance of producing Coso obsidian artifact production and exchange. They may well reflect substantial sociopolitical transformations generated from the production of artifacts for exchange and other social purposes (Allen 1986, 2011, 2013; Bettinger 1982, 2015; Ericson 1977, 1981, 1982, 1984; Gardner 2007; Sutton 1988b, 1996, 2017; Sutton et al. 2007). Comparison of the frequency and sources of obsidian debitage assemblages across different areas of the eastern Sierra, the Mojave Desert, and Southern California is an effective means to examine exchange and direct procurement strategies and connections among various populations at different times (Allen 2013; Bettinger 1982, 1999; Scharlotta 2014). Archaeological Research Design for the Antelope Valley Study Area 244 07A3822 Task Order 17 Rose Spring Period The Rose Spring Period (AD 225 to 1100) saw the introduction of the bow and arrow at the beginning of the period. The Sutton et al. (2007) chronological framework has pushed the onset of this period a few centuries earlier than most previous schemes (i.e., Coombs 1979; Sutton 1996; Wallace 1962; Warren 1984), which usually set it as lasting from about 1,500 to 700 years ago. Rose Spring sites are the most common prehistoric sites in the western Mojave Desert. Probably the most significant prehistoric technological transformation of the Great Basin was the introduction of the bow and arrow at the outset of the Rose Spring Period, or shortly thereafter. It is generally accepted in the Great Basin that the appearance of smaller Rose Spring projectile points indicates the introduction of bow and arrow technology which replaced use of the atlatl. It is also common for specialists in the region to posit significant economic and social changes that were at least partially set in motion by this technological innovation, thus accelerating social and economic changes that began in the late Gypsum Period. Bettinger (2015:44-49) notes the superiority of bow and arrow technology over atlatl weapons systems led to profound changes in eastern California in hunting capability (success rate, increased range of prey), group size (requires fewer hunters and less meat sharing) and reduced residential mobility. These changes played a central role in the diversification of the Numic family of Uto-Aztecan languages, and increased plant procurement to offset greater sedentism and reliance on smaller game with less fat. Analyses of obsidian quarries along the eastern Sierra were used by Ericson (1977, 1981, 1982, 1984) to argue that the introduction of the bow and arrow in this area led to consequential shifts in both lithic production and exchange systems, including the transition from producing large bifaces for exchange to generalized flakes suitable for modification into arrow points. However, debitage studies conducted near the Coso obsidian quarries by both Allen (1986) and Yohe (1998) suggest that this new weapon system did not affect the obsidian and production system as drastically as Ericson posited. Still, there is no doubt that the bow and arrow was a transformative technology that reduced high quality lithic material needs and greatly enhanced the effectiveness of hunters and, possibly, warriors. It is commonly argued by archaeologists in the region that the bow and arrow had an immediate impact on populations of bighorn sheep and other artiodactyls, and that this led to a shift towards small game for most of the period’s time span (Allen 2013; Bettinger and Eerkens 1999; Gardner 2007; Yohe 1998). Rose Spring corner-notched projectile arrow points are considerably smaller than those of earlier pre-bow and arrow temporal periods and, further, they may have diminished in size through time as a conservation measure (Acebo and Allen 2012). Sutton and others have developed a model that postulates significant social, settlement, and economic changes in the western Mojave Desert due to the onset of the Medieval Climatic Anomaly around 1,000 years ago (Allen 2011, 2013; Gardner 2002, 2007; Jones et al. 1999; Sutton 1996; Sutton et al. 2007). A period of warmer and drier conditions might have been a major factor in the near collapse of the Coso obsidian production and exchange system. At Sage Canyon on the western edge of the Mojave Desert, an assemblage of obsidian Rose Spring projectile points indicates lower Archaeological Research Design for the Antelope Valley Study Area 245 07A3822 Task Order 17 mass and size through time (Allen 2013; Acebo and Allen 2012). Even more convincing, several regional obsidian hydration databases reveal that the Coso obsidian production and exchange systems were at their maximum during the early Rose Spring Period, followed by a precipitous contraction around 1,000 years ago (Allen 2013; Gilreath and Hildebrandt 1997; Sutton et al. 2007). Late Prehistoric Period In the subsequent Late Prehistoric Period (AD 1100 to AD 1769) archaeological sites are smaller with shallow middens. Diagnostic Desert Series points (Cottonwood Triangular and Desert Side-Notched) are considerably more conservative in terms of material. There is evidently an even greater focus on plant processing over hunting compared to earlier periods. One other key technological addition in this period is the use of ceramic vessels for cooking and storage. It is conceivable that this new technology had an impact on lithic tool production or use, though this has yet to receive much consideration. Sutton and colleagues have noted that regional differences developed across the Mojave Desert during the Late Prehistoric Period and have argued that these patterns may correspond to the boundaries among the ethnographically documented Takic and Numic groups in the region (Bettinger 2015; Bettinger and Baumhoff 1982; Earle 2004, 2005; Sutton 1991, 1994, 1996, 2009, 2010, 2017; Sutton et al. 2007). It is posited that Cottonwood Triangular projectile points are predominant in the western and southern Mojave Desert, possibly serving as a Takic ethnic marker, while Desert Side-Notched points are more frequent in the northern and eastern Mojave Desert, and are perhaps associated with Numic people (Sutton 1996). If this model is correct, Cottonwood Triangular points should be far more common than Desert Side-Notched points during the Late Prehistoric Period in the central and southern Antelope Valley. It would also be instructive to consider projectile point styles compared to cultural groups in adjoining areas such as Southern California and the Central Valley. Mission Period The Mission Period (AD 1769 to AD 1835) in the Mojave Desert and adjoining areas is woefully understudied (Arkush 1990; Allen 2010). For example, it is not addressed in the most authoritative synthesis of the region (Sutton et al. 2007). Access to new materials and artifacts no doubt preceded more direct impacts on the societies of the region that intensified after the establishment of the Spanish mission system. While glass beads are common in archaeological sites in the adjacent mountains and the western Mojave Desert (Allen 2013; Sutton et al. 2010), other European artifacts or materials are much rarer. Glass and metal are both possible materials that may have been introduced into the Antelope Valley and other parts of the western Mojave Desert during the Mission Period. It is possible that such materials had an impact on lithic technological systems. Archaeological Research Design for the Antelope Valley Study Area 246 07A3822 Task Order 17 Research Questions and Data Needs Questions 1) Was there specialized production of large fine-grained volcanic (rhyolite, basalt) bifaces during the Lake Mojave and Pinto Periods in the Antelope Valley? 2) Was there specialized production of cryptocrystalline silicate (chert, chalcedony, jasper) flake tools for activities such as butchering and plant processing during the Lake Mojave and Pinto Periods in the Antelope Valley? 3) Was there specialized production of large cryptocrystalline silicate bifaces, especially dart points, for hunting large and medium mammals during the Gypsum Period in the Antelope Valley? 4) Was there a reduction of biface production and an increase in the production of smaller flakes suitable for use as smaller arrow projectile points during the early Rose Spring Period in the Antelope Valley? 5) Did projectile point size continue to decrease during the late Rose Spring and Late Prehistoric Periods due to conservation of high-quality materials such as obsidian and/or changes to hunting smaller mammals in the Antelope Valley? Previous research in the western Mojave Desert and other areas of the southwest Great Basin has suggested changing patterns of specialized lithic production from the early Holocene to the Late Prehistoric Period. Specialized production can be detected by the preponderance of a tool or debitage type, such as the ubiquity of biface thinning flakes and the widespread distribution of large well-made atlatl spear points during the Gypsum Period which together point to specialized biface production. Another possible pattern is to find restricted production sites with unusually high frequencies of a debitage type or possible broken and rejected blank tool “preforms.” Such sites would likely be located in proximity to source material. 6) Do lithic reduction strategies become more efficient over time in the Antelope Valley? In addition to changes in specialization of types of tool production, it is likely that there were accompanying changes in lithic reduction strategies to more efficiently produce desired types of tools in the Antelope Valley. Increased efficiency could be discerned through less waste of material, less costly production techniques, or new approaches that generate products with less time or other cost. These could include changes in material selection, as well as the techniques used to reduce cobbles and cores into finished products. This would include changes such as direct versus indirect percussion, hard vs. soft hammers, and the use of bipolar reduction to exploit denser material such as fine grained volcanic rock or granite, or heat treating cryptocrystalline silicate material to make it easier to pressure flake. Related to this would be the degree to which lithic material was conserved. In general, bipolar reduction and biface production utilize far more raw material than production of flake tools from secondary flakes. Archaeological Research Design for the Antelope Valley Study Area 247 07A3822 Task Order 17 Data Needs The research questions provided above can be addressed through analyses of lithic tools and debitage assemblages from the Antelope Valley. Diagnostic artifacts such as projectile points directly reflect changes in technology and specialization through time. Unfortunately, these are often not present in large numbers at many sites in the region, particularly at lithic production sites located close to quarry or lithic sources. They are also the most commonly collected surface artifacts. Question 1E can only be answered by adequate samples of recovered projectile points. Biface and uniface tools provide another means to address the research questions as they reflect either preforms of projectile points or tools used for other functions such as cutting and chopping. While not as readily assigned to temporal period, because they are not diagnostic, artifacts found in context with dateable deposits can be used to assess specialization through time. Bifaces are particularly useful as they reflect stages of production of tools or preforms. Debitage assemblages have the highest potential for addressing the research questions, given their ubiquity and large sample sizes. The key challenge is temporal context. The debitage classification system developed by Allen (2013) for western Mojave Desert sites readily distinguishes production of bifaces from secondary flakes suitable for modification into expedient flake tools, more specialized flake tools, or smaller projectile points. It also permits the classification of flakes and shatter to reflect both early and later stages of tool production. Cores are important indicators of tool production sites and can often distinguish between the production of flake tools or large bifaces. Datasets of debitage and tools can also be combined to produce indices and ratios that can be compared to measure changes in lithic production. Changes in biface production through time or across different sites can be readily measured through a biface production index derived from the ratio of biface thinning flakes to secondary flakes (Allen 1986, 2013). Higher ratios reflect greater production of bifaces compared to flake tools. It is also possible to assess the production of biface blanks for exchange versus local consumption through a biface exchange index of dividing the number of biface thinning flakes by number of bifaces from a site. Changes in lithic reduction strategy can be reflected in debitage. Hammer stones, cores, primary flakes, large biface thinning flakes, shatter, and flakes with cortex are expected to be more common in quarries or initial production sites near quarries where conservation of raw material would not have been a concern. In contrast, reduction strategies favoring the conservation of material should be reflected in sites far from sources. Tertiary or pressure flakes and secondary flakes should be more common in such contexts. Archaeological Research Design for the Antelope Valley Study Area 248 07A3822 Task Order 17 Theme: Lithic Material Sources for Flaked Stone Tools and Other Artifacts Obsidian Obsidian was one of the most prized resources of western North America during prehistory (Shackley 2005). Based on geographic proximity and previous archaeological research on obsidian artifacts in the western Mojave Desert, the Coso Range sources provided almost all of the obsidian utilized by prehistoric populations in the Antelope Valley. These sources are located some 120 km north of the center of the Antelope Valley, likely a four to five-day trip on foot (somewhat longer for an encumbered traveler). Early studies of the Coso Volcanic Field were conducted by Elston and Zeier (1983, 1984), but the most authoritative archaeological analysis to date is that of Gilreath and Hildebrandt (1997). They have also produced a more recent study of production and exchange of Coso obsidian (Gilreath and Hildebrandt 2011). Other important studies focused on Coso Volcanic Field subsources were conducted by Hughes (1988) and Eerkens and Rosenthal (2004). The Coso Volcanic Field is described by Gilreath and Hildebrandt (1997:7) as: characterized by numerous explosion craters, rhyolitic domes, debris flows, and pyroclastic deposits, most originating from volcanic events that occurred between 1.5 million and 33,000 years B.P. ... naturally occurring obsidian is abundantly present throughout ... and available from a variety of contexts ... these include several primary outcrops of glass flowing from the sides of steep rhyolitic domes, with high quality obsidian often occurring as large boulders and slabs ... secondary quarries occur as obsidian float in major debris flows or in concentrations of air fall sporadically scattered across the land during volcanic eruptions ... the amount of useable obsidian in the most extensive secondary deposits, however, seems inconsequential when compared to the amount at extensive primary quarries. These secondary quarries occur on ridgetops, exposed as lag after fine-grained sediments have eroded away. Hughes (1988) examined ratios of rubidium (Rb) and zirconium (Zr) across the field and distinguished four major subsources: Sugarloaf, West Sugarloaf, West Cactus Peak, and Joshua Ridge. While these are chemically distinct, it appears that their hydration rates do not vary significantly (Gilreath and Hildebrandt 1997:11). This is important as it makes obsidian hydration values from different assemblages of Coso obsidian nonetheless comparable. Gilreath and Hildebrandt (2011:173-174) point out that, “the widespread distribution of Coso glass throughout southern California has led to much interest in determining a reliable hydration rate for it … for that reason it has the dubious distinction of having more hydration-rate formulations than any other geochemically distinct glass in the world ... no fewer than 20 rates have been proffered for Coso obsidian over the years.” The most accepted hydration rate is that of Basgall (1990), who accounted for effective temperature rates. More recent studies include those of King (2004) and Rogers (2007). Eerkens and Rosenthal (2004) Archaeological Research Design for the Antelope Valley Study Area 249 07A3822 Task Order 17 argue that of the four major subsources, West Sugarloaf was most suitable for trade as it was both accessible and readily provided large pieces suitable for biface blanks. Other major obsidian sources are located to the north of Coso along the eastern Sierra. Ericson (1977, 1981, 1982, 1984) compared these sources and analyzed their distributions. These include Fish Springs, Casa Diablo, Mono Glass Mountain, Mono Crater, and Bodie Hills, among others. His work would suggest that at least a small amount of obsidian from these more distant quarries penetrated the Coso region and was distributed into the Antelope Valley and other areas of the western Mojave Desert and adjoining regions. While Coso Range sources provided almost all of the obsidian found in archaeological sites in the Antelope Valley, small amounts of obsidian found on Edwards AFB have been positively sourced to Casa Diablo and the Queen source in the northern Owens Valley (Earle et al. 1997). Obsidian Butte material from the south end of the Salton Sea in the Colorado Desert is present within some archaeological sites in the Antelope Valley (Sutton 1989, 2009). Obsidian from this source is found in many sites in the Colorado Desert, but it was periodically unavailable due to episodic filling of Lake Cahuilla (Wilke 1978). There are other obsidian sources in Baja California (Panich et al. 2017), but obsidian from these sources does not appear to have been found in the Antelope Valley. Finally, small and relatively unknown sources of obsidian elsewhere in the Mojave Desert in California or Nevada may have also been minor suppliers to the Antelope Valley region, as might obsidian from sources east of California. Amounts from such sources should be minimal, and perhaps even nearly undetectable (Hughes and Milliken 2007). Obsidian is common in archaeological sites in the Antelope Valley, but in much more limited frequencies than in western Mojave Desert sites further to the north (Allen 2013; Kaldenberg et al. 2009; Sutton 1991). One robust study of obsidian sources for a site (CA-KER-7055) in the northern Antelope Valley that dates to the Gypsum and Rose Spring Periods was conducted by Scharlotta (2014:230). One hundred percent of 29 sourced artifacts were from the West Sugarloaf subsource of the Coso Volcanic Field. Given higher degrees of mobility in the earlier temporal periods of the Mojave Desert, and the peak use of the Coso sources during the Gypsum and early Rose Spring Complexes, it might be predicted that earlier sites in the Antelope Valley are more likely to exhibit more variable obsidian sources than later ones. Obsidian can be non-destructively sourced through portable x-ray fluorescence (PXRF), and this technique should be applied consistently in the Antelope Valley to better understand obsidian use through time. Obsidian evidently saw considerable changes through time in its desirability for particular tool types in the Mojave Desert region. In the Early and Middle Holocene Lake Mojave and Pinto Periods, it was not commonly used as a material for projectile points, but it is present in many sites as flake tools and sometimes bifaces. With the emphasis on hunting during the Gypsum Period, obsidian was frequently employed for large and carefully made projectile points and bifaces which served as both cutting and slicing tools as well as cores for flakes. With the transition to the bow and arrow during Archaeological Research Design for the Antelope Valley Study Area 250 07A3822 Task Order 17 the Rose Spring Period, smaller flakes were modified into arrow points and the frequency of obsidian biface cores decreased. Obsidian continued to be a material of choice during the Late Prehistoric Period, though point sizes decreased markedly. Rhyolite Rhyolite is frequently present in lithic assemblages from archaeological sites in the Mojave Desert and adjoining areas, though it is often argued that it is somewhat more common in deposits from the Early and Middle Holocene (during the Lake Mojave and Pinto Periods). Like basalt and other similar fine-grained volcanic materials, rhyolite is not very brittle (and is thus relatively difficult to flake) but is strong (and thus durable). Many archaeologists have postulated that it was particularly attractive for more mobile populations that moved at times far from lithic sources. The Fairmont Butte rhyolite source is one of the more well-known lithic material sources within the Antelope Valley (Glennan 1970, 1971; Scharlotta 2010a, 2010b, 2014; Sutton 1982a, 1988, 1989, 1993). The volcanic formation is located to the west of the city of Lancaster in the southern Antelope Valley. Dozens of recorded archaeological sites near the butte, particularly a large quarry site (CALAN-898), are part of a continuous distribution of rhyolite debitage and artifacts that extends several kilometers. Archaeological interest in this production center focused for a time on the model for an early Pinto Complex “Rhyolite Tradition” (Glennan 1970, 1971; Sutton 1982a, 1988). The focus was the possible antiquity of the quarrying activity or whether it was mostly conducted during the late Holocene. While much of it seems to date to late prehistory, there is evidence that rhyolite was exploited there at least as early as the Pinto Complex. Later, investigations in the Rosamond Hills in the northern Antelope Valley by Sutton (1993) documented a second major rhyolite source for the region. Smaller rhyolite quaries have been documented at Little Buttes in the central Antelope Valley, Red Hill on Edwards AFB, and Opal Mountain and Black Canyon to the east of the Study Area (Peck 1949; Giambastini et al. 2007: 212). Recent innovative research by Scharlotta (2010a, 2010b, 2014) has focused on the production and exchange of Antelope Valley rhyolite. His first major contribution (2010a, 2010b) was to develop a method for sourcing this material, “by microsampling the groundmass of rhyolite using laser ablation-time of flight-inductively coupled plasma-mass spectrometry” (Scharlotta 2014:224). Samples analyzed with this technique from four Antelope Valley archaeological sites were determined to be from Rosamond Hills (nearly 82%), Fairmont Butte (nearly 11%), and unknown sources (roughly 7%). Fairmont Butte exploitation, then, is somewhat exaggerated in the archaeological literature, with Rosamond Hills the more intensively utilized source of rhyolite. Scharlotta (2014) then examined available archaeological data and ethnographic and historical accounts to develop a model of stable resource procurement systems across the western Mojave Desert that lasted at least from 1500 to 300 BP. Scharlotta’s research provides an excellent means to investigate how sites in the Antelope Valley relate to long-term production and exchange systems, as well as dynamic ethnic boundaries and affiliations. The Fairmont Butte rhyolite source may have been Archaeological Research Design for the Antelope Valley Study Area 251 07A3822 Task Order 17 within the territory of a Serrano clan during the Late Prehistoric and Mission Periods (see the Ethnohistory section). This may have limited the distribution of rhyolite from the Fairmont Butte source to other areas of the Antelope Valley. Rhyolite was desirable as a material for projectile points during the Lake Mojave and Pinto Periods but was rarely chosen for later projectile points. It was more consistently used throughout all cultural complexes for flake tools and bifaces. Basalt Basalt is another potentially fine-grained volcanic material used for flaked stone tools in the Mojave Desert and adjacent regions that shares many of the characteristics and patterns of use with rhyolite. Basalt is more ubiquitous across the region, though its quality (i.e., grain size) for use as stone tools varies considerably. In general, basalt is more common in the central and eastern Mojave Desert than the western given the prevalence of more recent volcanic activity in these areas (Dibblee 1954, 1960, 1967; Noble 1954; Smith 1964; Troxel 1962). Like rhyolite, basalt was mostly desirable as a durable and strong material for tasks which did not require precise slicing or cutting. However, during the Lake Mojave Period, and especially the Pinto Period, it was widely employed for crude projectile points that might have functioned as stabbing spear tips (Sutton et al. 2007:238) in addition to atlatl darts or spears. It was occasionally used for bifaces in later time periods, but these are limited to early-stage bifaces since it is extremely difficult to remove small pressure flakes from basalt tools. Unfortunately, little progress has been made in identifying the sources of basalt tools and debitage within the central or western Mojave Desert. This would require a large program of research, given the ubiquity and diversity of basalt sources, each of which would have to be adequately sampled. At a larger scale, Jones et al. (2003), however, have mapped finegrained volcanic “conveyance zones” across the entire Great Basin. Cryptocrystalline Materials The grouping of materials known as cryptocrystalline silicates (CCS) (chert, chalcedony, jasper) is the most common lithic material for flaked stone tools and usually for debitage in the western Mojave Desert. These materials are locally available throughout the Mojave Desert and can be viewed as one of the region’s key resources for external exchange (Davis 1961). It is important to note that archaeological and geological taxonomies of CCS materials are often not congruent, but archaeologists frequently do share “folk categories” that are standardized within regions (Luedtke 1992:6). Generally, in the Mojave Desert most archaeologists can readily distinguish chert from chalcedony (usually translucent) and jasper (homogenous deep red and mustard colors), even if geologists would find considerable fault with the classification system. However, in this case, it is likely that the archaeological system is better attuned to the emic systems of past flintknappers than the geological one. Still, it is common for archaeologists to eschew the perceived differences among Archaeological Research Design for the Antelope Valley Study Area 252 07A3822 Task Order 17 silicates and simply lump them together as CCS. Luedtke (1992:8) notes that even this system is inaccurate, as most cherts defined by archaeologists have quartz grains so large they are technically microcrystalline (larger than 2µ and less than 50µ in diameter). Nevertheless, CCS is standard archaeological nomenclature, and it is used here. Unfortunately, sourcing CCS material in the region with accuracy is not yet possible. Attempts to do so essentially rely on macroscopic variables such as color and homogeneity. CCS sources are also extremely common in the Mojave Desert, and frequently particular sources are characterized by variation in material. To date, no attempts have been made to develop a comprehensive survey of available CCS sources in the region. Such a project would entail using geological maps and surveys (Dibblee 1954, 1960, 1967; Noble 1954; Smith 1964; Troxel 1962) to identify potential deposits with subsequent inspections. While the CCS sources are poorly documented thus far, there is little doubt that they were numerous in the Antelope Valley and adjacent regions. Sutton (1988:15) states, “sources appear to be located on the eastern fringe of the Antelope Valley ... these silicates include jasper, chert, chalcedony, and quartzite, and come in a variety of colors.” CCS sources are also common in the Rosamond Hills, Bissell Hills, Brown Butte, North Edwards Hills, Castle Butte north of the Study Area, and in the Kramer Hills east of the Study Area (Sutton 1993:1; Giambastini et al. 2007: 212). CCS was used extensively for a wide variety of tool types throughout the entire prehistoric sequence of the Mojave Desert, including projectile points, bifaces, unifaces, and retouched and utilized flakes. Macroscopic attempts to source CCS artifacts in the Antelope Valley have relied on color, luster, and homogeneity of the material to try and pinpoint quarries or outcrops. Each source contains material with a variety of colors and translucencies making macroscopic sourcing difficult (Earle et al. 1997). Despite this, various researchers have attempted to develop generalities for this process, but no chemical analyses have been conducted to verify the accuracy of these assertions. CCS categorized as a red to brown jasper is often attributed to the Kramer Hills CCS source to the east of the Study Area, although the Kramer Hills also contain a white/tan chert with vitreous to chalky luster (Perry 1989; Wessel 1990; Giambastini et al. 2007: 212). The Bissell Hills chert has been described as translucent to opaque and can be off-white to brown in color (Perry 1989; Wessel 1990). Heat treatment or thermal alteration of CCS “involves the intentional heating of chert to bring about desired changes, usually to improve its flaking properties . . . heat-treating also produces dramatic color changes, which in some cherts may have been a secondary, or even a primary goal . . . this process was used rather commonly by prehistoric people, at least in North America” (Luedtke 1992:91). Wood fires can easily generate temperatures sufficient to thermally alter chert, but thermal shock is possible if temperatures are too high, if the material being heated is too large (such as a cobble), or if the temperature changes are too rapid. Given these considerations, heat treatment of chert in the Mojave Desert would most likely be employed on flakes rather than large bifaces or cores. From a functional perspective, the most likely reason to heat treat chert is that it makes it “less tough, more elastic, and therefore much easier to knap, and that it responds especially well to pressure flaking” (Luedtke 1992:96). Since pressure flaked CCS projectile points and bifaces become Archaeological Research Design for the Antelope Valley Study Area 253 07A3822 Task Order 17 common starting in the Gypsum Period, heat treatment of CCS should have been more common in the last few thousand years in the Antelope Valley. Quartz Quartz is ubiquitous in both the Mojave Desert and surrounding mountain ranges (Dibblee 1954, 1960, 1967; Noble 1954; Smith 1964; Troxel 1962). Although quartz does not flake well, there is usually a small percentage of quartz debitage in the assemblages of archaeological sites, often with a high percentage of shatter rather than flakes. There are also small numbers of tools produced from quartz, including early stage bifaces, unifaces, cores, and even projectile points. The strength and durability of this material would have made it desirable, perhaps most often when finer-grained lithic materials were difficult to access. It is also possible that it was desirable as a material for aesthetic or other reasons since it usually exhibits marked translucence. Quartz crystals have been identified as serving a variety of functions including as pressure flakers for tool production, and as important items with ideological significance. Fused Shale and Related Materials Fused shale, a metamorphic rock that is semi-vitreous due to heat and pressure, was an important stone tool material for coastal southern California, particularly when obsidian was not easily accessible. It is often mistakenly identified by archaeologists as obsidian from Obsidian Butte in the Colorado Desert (Hughes and Peterson 2009). Firmly identified source areas are limited so far, with most coming from Monterey Formation sources in Ventura County (Grimes Canyon) and Santa Barbara County. Differences in trace elements permit fused shale to be sourced with x-ray fluorescence analysis (Hughes and Peterson 2009). The peak of use of fused shale seems to be during late prehistory and the protohistoric period, perhaps because available material is usually of small size, meaning that it was not as desirable until the advent of smaller projectile points after the development of the bow and arrow. Fused shale does not seem to have been commonly imported to the Mojave Desert, but given the proximity of the Antelope Valley to its source areas and trade routes through passes in the Transverse Ranges, it is possible that it exists in the region in limited quantities. Given its similarity to obsidian, it is quite possible that previous archaeological investigations failed to recognize fused shale at sites in the western Mojave Desert. Steatite and Schist for Groundstone Although it is unlikely that steatite (talc schist) or schist were utilized as flaked stone tools, they were utilized for a variety of ground stone tools and ornaments. An important source of both materials is found at a quarry in the Sierra Pelona, mountains located south of Leona Valley on the south side of the Antelope Valley (Eddy 2013; Landberg 1980; Rosenthal and Williams 1992; Sutton 1982a). Sutton (1982:15) describes it as “a large outcropping exposed in a cliff” ranging “from a poor-quality schist Archaeological Research Design for the Antelope Valley Study Area 254 07A3822 Task Order 17 to an excellent steatite.” Steatite was commonly used for the production of stone bowls and mortars, as well as for stone beads, effigies, charmstones, pipes, and other artifacts. Eddy (2013) pioneered research on conducting trace element analysis of talc schist sources and artifacts in southern California and the Mojave Desert, and his work shows that artifacts made from Sierra Pelona material are widely distributed. Steatite, and perhaps schist, from this quarry was an important raw material for both local consumption and trade outside of the Antelope Valley. Schist was often used to make flat ground stone artifacts that could serve as comals (griddles for cooking over open fires). It was more widely available than talc schist, and so might not have been exported to any extent. Hematite and Other Materials for Pigments Hematite, a red colored anhydrous iron oxide, is a major component of red ochre. Red ochre has a long use, dating back to the earliest art styles of the Paleolithic in the Old World. It was widely used for body painting, to decorate artifacts, and as a material for making pictographs. Red is not just a primary color, it is also commonly symbolically associated with themes such as life, blood, fertility, and power across human societies in the Old World, New World, and the Pacific. Hematite is common in areas with volcanic material, so it might be expected in the volcanic buttes of the Antelope Valley, as well as in geological formations in the adjacent mountains and the central and eastern Mojave Desert. Hematite has been identified within Anaverde Formation sedimentary rock units in the San Andreas Rift Zone (Padon 1997). Little archaeological research has yet been directed towards sourcing hematite or similar minerals in the western Mojave Desert, though these are known to be important materials through ethnographic accounts. Even the study of rock art, common in the region, neglects much discussion of the minerals used as pigments in the production of pictographs or other applications. More effort should be directed towards identification of sources, uses, and exchange networks of hematite and similar minerals in the study region. Research Questions and Data Needs Questions 1) Can the results of Scharlotta’s (2010a, 2010b, 2014) work in the region to source rhyolite and examine its distribution be confirmed through further application of laser ablation-time of flightinductively coupled plasma-mass spectrometry analysis? 2) Does the distribution of Antelope Valley rhyolite support Scharlotta’s findings of “stable populations and trade networks for more than 1,500 years, with possible disruptions during the Late Prehistoric Period around 300 BP.” (Scharlotta 2014:240)? The local abundance of rhyolite sources in the Antelope Valley (especially Fairmont Butte and the Rosamond Hills), and the prevalence of rhyolite in archaeological sites in the region should be a central focus of research. Archaeological Research Design for the Antelope Valley Study Area 255 07A3822 Task Order 17 3) Was fused shale an important alternative to obsidian in the Antelope Valley, and if so what were its sources and when was it used? Given its proximity to regions that utilized fused shale to a significant extent, its presence or absence in the Antelope Valley is of interest. 4) Did the use of CCS vary significantly through time in the Antelope Valley and to what extent were variations in its use due to availability of other materials such as obsidian? CCS was the most important material used to produce formal tools and expedient flake tools in the western Mojave Desert throughout prehistory. 5) In the Antelope Valley was there a peak of obsidian use during the late Gypsum and early Rose Spring Periods followed by a significant decline? Obsidian production and exchange has been subjected to far more analysis by archaeologists in the southwest Great Basin than any other lithic material. Archaeological research in the Antelope Valley can contribute significantly to these discussions. 6) Is obsidian from sources other than Coso restricted to certain time periods or certain geographic areas within the Antelope Valley Study Area? Obsidian from sources other than Coso is rare in the Antelope Valley. As more obsidian artifacts are sourced, patterns in their temporal and geographic distribution may become apparent. 7) Did residents of the Antelope Valley favor certain CCS sources over others? CSS can be found in a variety of locations throughout the Valley. The material varies in color, transparency, and luster within individual source locations making sourcing through macroscopic analysis difficult. Data Needs Chemical investigations of lithic materials found at archaeological sites are required to address most of the research questions posed here. Obsidian is the most understood material, and the sources of obsidian found in archaeological sites can be readily accomplished through x-ray fluorescence (XRF) or PXRF analyses to identify trace element composition. Each documented obsidian source has a different trace element signature. Obsidian also has the distinct advantage of also providing a time period of use through obsidian hydration measurements. Scharlotta’s (2010a, 2010b, 2014) analysis of Antelope Valley rhyolite sourcing and exchange networks suggest that these methods can be employed on this fine-grained volcanic material as well. Other more ubiquitous fine-grained volcanic materials such as andesite or basalt are not yet well enough documented to allow similar analyses. Fused shale has been shown by Hughes and Peterson (2009) to be another prehistoric and protohistoric lithic material that can be sourced through XRF analysis in southern California. Unfortunately, CCS sources are far more varied and to date no successful attempts to identify chemical signatures for these in the region are available. Archaeological Research Design for the Antelope Valley Study Area 256 07A3822 Task Order 17 Chemical investigations are not required for analysis of the relative importance of lithic material sources through time. These questions can be assessed through comparison of counts and frequencies of artifacts from surface collections and test excavations. Archaeological Research Design for the Antelope Valley Study Area 257 07A3822 Task Order 17 Theme: Prehistoric Population Movements The study of prehistoric population movements has historically depended on both archaeological and linguistic inference, and more recently on genetic analysis of population cladistics. The internal analysis of linguistic data in particular gleans clues about the patterns of dialectical and linguistic divergence between related languages that would provide indications about how long ago specific languages had diverged from a common ancestor, and thus inferences on population movement. Archaeological analysis of population movements has focused on evidence for the geographical displacement over time of the distinctive material culture signatures of cultural groups. Genetic analysis has attempted to identify cladistics relationships between living members of cultural groups, or between their ancestors - via work with archaeological genetic samples - to elucidate population relationships and population movements in the past. With respect to California and the Great Basin, because of the nature of the archaeological record generated by hunter-gatherer societies, the tracking of population movements has been a particular challenge. The relationship between long-term continuity in material culture features related to exploitation of the environment and an inferred history of population movements has not been easy to sort out. In addition, the nature of both the linguistic and archaeological analyses used in looking at population movement has tended to emphasize arrival rather than departure; specifically, a focus on time of arrival for indigenous populations in the region that were present at Spanish contact, rather than seeking an understanding of previous populations and what happened to them. In addition, the archaeological time scale developed for southern California and adjacent regions is fairly immense by the standards of some other archaeological regions in the world. The fact that the region has a continuous shell bead stylistic typology that commences at 8000 BP is an example of this deep-time archaeological continuity. Attempting to deal with population movements in this kind of prehistoric time scale is a challenge, in part because of the time depth limitations on the reconstruction of linguistic relationships between languages having a common origin. The discussion herein focuses on several presumed episodes of population movement into southern California, and consequently the Antelope Valley region, during the Middle and Late Holocene (after 8000 BC). These episodes are derived primarily from linguistic inferences, with some support from the few available studies of the archaeological record and genetic analysis. This is followed by a discussion of archaeological correlates that may possibly be used to track (or identify) such population movements through time. Archaeological Research Design for the Antelope Valley Study Area 258 07A3822 Task Order 17 Uto-Aztecan Speakers Theories on Origins of Uto-Aztecan Speakers Golla (2011) classifies Uto-Aztecan as one of five primary language families represented in aboriginal California, along with three linguistic isolate groups. It is one of the most geographically extensive in North America (Golla 2007). This language family consists of two divisions that generally correspond with the distribution of prehistoric human populations in the western United States (Northern UtoAztecan) and Mexico (Southern Uto-Aztecan). Specific to this discussion, the Northern Uto-Aztecan branch is further subdivided into east and west divisions known as Numic and Takic/Californian language groups, respectively. Linguists have disagreed about the origin and development of Uto-Aztecan populations found in the western United States. Hill (2003) has proposed that this language family originated in Mexico, at a place of origin where some of Uto-Aztecan groups had acquired agriculture and was transferred through population migration to the southwestern United States. This scenario was based on a theory developed by an archaeologist, Bellwood (2003), who had promoted the concept of ancient farming populations in different parts of the world simultaneously spreading agriculture and language families into new areas, driven by population pressure. The Mesoamerica origin theory has been critiqued by Merrill et al. (2009). They assert that Hill’s claim of true cognate terms related to maize existing for Southern Uto-Aztecan and Northern Uto-Aztecan languages is faulty, that the Southwestern sites where maize was first introduced were occupied by local foragers and not by inmigrating farmers, and that maize’s early Mesoamerican companion, squash, arrived in the Southwest much later than maize (Merrill et al. 2009:21023, 21024). They also criticize the argument that Uto-Aztecan farmers in northern Mesoamerica 4,000 years ago would have been compelled to migrate by population pressure. Other researchers have argued along with Merrill et al. (2009) that Uto-Aztecan speakers originated in the western United States, with some of the population subsequently migrating southward and southeastward towards Mesoamerica (Fowler 1983; Nichols 1981; Golla 2007, 2011). Fowler (1983) noted that the botanical lexicon of proto-Uto-Aztecan contained terms that located the Uto-Aztecan homeland in the western United States. This second scenario appears to be more accepted within the archaeological community based on the evidence gleaned from studies to date (see discussion below). Nichols (1981) placed the origin of proto-Uto-Aztecans in the territory of the Northern Paiute in the Great Basin. Nichols claimed, on linguistic grounds, that there was evidence of ancient linguistic borrowing between Hokan speakers—ancient Californians—to the west of the Sierra Nevada and the proto-Uto-Aztecans. He advanced the proposal that the Uto-Aztecans had come to occupy portions of the Sierra Nevada and the Central Valley before being pushed south by a movement of Penutian speakers in more recent times who were moving from Northern to Central California. Thus, the presence of Takic speakers in Southern California as part of this Uto-Aztecan community might be Archaeological Research Design for the Antelope Valley Study Area 259 07A3822 Task Order 17 seen in Nichols’ scenario as the result of them having been pushed southward and southeastward from the Central Valley. Sutton (2010) has also proposed that at around 3500 BP (1500 BC) Takic speakers were pushed out of the Central Valley by Penutian speakers and entered Southern California and the Study Area (Figure 11). There has been little archaeological support or further linguistic research bolstering this proposal. Fowler (1983) proposed a homeland for proto-Uto-Aztecans in an area encompassed somewhere between the eastern Mojave Desert and the Sonora and Chihuahua deserts to the south (Figure 12). Here, a linguistic antiquity time depth for the Uto-Aztecan language family has been placed on the order of about 5,000 years, similar to the time depth for Indo-European. According to this scenario, proto-Uto-Aztecans would have diversified into a western branch that would include seed-gathering foragers who would come to occupy portions of south-central and Southern California, and an eastern branch that would include agricultural populations such as the Hohokam and the Anasazi. According to this scenario, Yuman speakers later moved north up the lower Colorado River into the proto-Uto-Aztecan homeland area, creating a sort of split between the western and eastern divisions of this proto-Uto-Aztecan language family (Takic and Numic). This model involves the presence of Uto-Aztecan speakers in desert California at a relatively early date, although the exact scenario and timing for their expansion from the desert interior to the coast is open to interpretation. The notion that Tubatulabal speakers have been in place in the southern Sierra for thousands of years, appears to support a scenario for an early presence of Uto-Aztecans in interior California (Golla 2007:74) (also see below). Linguistic Interpretations of Diversification and Movement of Uto-Aztecan Groups Golla (2007, 2011) presents a reconstruction of the diversification and development of Uto-Aztecan that builds on Fowler’s (1983) interpretation of its origin. This reconstruction is adopted herein and is focused on the Mojave Desert and Antelope Valley. It includes discussion of when and where protoUto-Aztecan developed, the circumstances of the divergence between the Takic and Numic languages, and how long ago Serrano/Kitanemuk was established in place as a distinct language. However, many linguists recognize that the assumption basic to historical linguistics, that the rates of divergence of related languages are consistent, frequently does not hold true (Blust 2000; Gray et al. 2011). Thus, such estimates for the time scales of language divergence, if not corroborated by other lines of evidence, are open to debate. As of circa AD 1800, the southern Antelope Valley, southeast and northwest of Palmdale, was occupied by members of a desert division of the Serrano, a Takic-speaking population. A portion of the northwest side of the valley also corresponded to the territory of the Kitanemuk, who spoke a dialect of Serrano. The Numic-speaking Kawaiisu occupied the Tehachapi Valley and used desert areas to the east, on the north side of the Antelope Valley. Analysis of the process of divergence between the Takic and Numic languages, and of the development of Serrano, is key for understanding population movements in the Antelope Valley.

Proto-Uto-Aztecan Homeland Golla (2007, 2011) has provided a scenario for the presence of Uto-Aztecans in the Mojave Desert and the Antelope Valley. He proposed that between 3,500 and 2,500 years ago, emerging dialectical groups of proto-Uto-Aztecans were ranged between the southern Sierra and the Colorado River across the Mojave Desert. One of the locations of this range of emerging Uto-Aztecan languages would have been the Kern River drainage occupied by the Tubatulabal. The Tubatulabal language was treated in 2007 by Golla as a linguistic isolate in relation to both the Takic and Numic branches of Uto-Aztecans. In 2011, he tended to classify Tubatulabal as being more similar to most of the Takic languages than Serrano/Kitanemuk was. Under this scenario of the occupation of the Mojave Desert between the Colorado River and the southern Sierra, Golla treats the Tehachapi Pass area and the territory of the Kitanemuk just to the south of it, as an original homeland for the Takic languages. If this is indeed the case, then it can be assumed that this original location for what may be referred to as proto-Takic would include portions of the immediately adjacent Antelope Valley. In his 2007 discussion, and also in 2011, Golla treats the process of diversification of the Takic languages as taking about 2,000 years. He states that it is clear that the northern Takic languages, particularly Serrano/Kitanemuk in respect to Gabrielino, are the most highly diversified. That would mean that Gabrielino and Serrano/Kitanemuk had first diverged from one another. He notes that Jane Hill (2003) had proposed abandoning the Takic label altogether and creating a California branch of Uto-Aztecans that would consist of Serrano/Kitanemuk as a separate group and would lump Tubatulabal, Gabrielino, and Cupan together as languages that were more similar to one another than to Serrano. Golla states that the diversification of the Cupan languages, including Luiseño, Cupeño, and Cahuilla had occurred at a much more recent date, possibly within the last thousand years or so. This would suggest a late date for the merging or melding of Takic and Yuman cultural features among the Luiseño in Riverside and San Diego counties. Golla (2007:74) also notes that Moratto’s (1984) date of 3500-2500 years BP for the Uto-Aztecan arrival on the coast appears to him to be too early. It is noted that the relatively late dates for the spread of the Cupan languages to the south may fit with some archaeological findings for the San Luis Rey area (see discussion below). For the Antelope Valley region, the idea of proto-Takic speakers being in place in the western Antelope Valley as early as 3,500-2,500 years ago would suggest that whatever innovations in material culture were seen archaeologically after the middle Gypsum Period, circa 2,700 years ago, would not be indicators of the initial arrival of Takic-speakers. This would therefore call into question, for the Antelope Valley area, the validity of the late arrival scenarios associated with the introduction of the bow and arrow or Cottonwood Triangular points (circa AD 600 to 900). As discussed below with respect to theories about Yuman presence in the Mojave Desert, Golla also proposes a relatively shallow time depth for the diversification of the Yuman languages. His interpretation of the diversification of the Takic and Yuman languages as being relatively recent could be viewed as frustrating for archaeologists seeking to understand the distribution and Archaeological Research Design for the Antelope Valley Study Area 263 07A3822 Task Order 17 displacement of language groups within the deep time scale of Southern California prehistory. Golla limits the time scale of Yuman-Takic interaction to 1,000-1,200 years BP, and of Takic diversification to 2,000 years BP. This raises the question of whether linguistic analysis can shed any light on the interaction and displacement of language groups before those dates. It is noteworthy that the region where Golla’s language analysis is most friendly to archaeology in terms of maximally pushing back the dates for an in-situ presence of Proto-Takic is the region surrounding the Antelope Valley. The Numic Homeland and the Numic Expansion The geographic area where the split between the Takic and Numic branches of Uto-Aztecan occurred appears may have included the northernmost reaches of the Antelope Valley. Golla (2011:256) places the original Numic homeland in the eastern Sierra between Mono Lake in the north and Owens Lake in the south. The well-known theory of the Numic expansion proposes a radiation of Numicspeaking foragers eastward and northward across the Great Basin as early as 1,000 years ago. For the Antelope Valley region, the key issue has been how close the original Numic homeland may have been to the northern margin of the valley. This raises the question of whether the Kawaiisu of the Tehachapi region and desert areas to the north of the Antelope Valley were already there before the Numic expansion, or whether their arrival there was part of this process or even postdated it. Sutton has proposed that the occupation of the Tehachapi region by the historic Kawaiisu postdated the early Rose Spring/Saratoga Springs Period, and was a response to drought around AD 1000 displacing this group out of the Mojave Desert. It is not clear, however, that the arrival of the Kawaiisu in the region may not have dated to earlier Rose Spring/Saratoga Springs times. For the Late Prehistoric Period, Sutton (1989, 1991) referred to what he saw as archaeological evidence of a newly created ethnic boundary: A regional boundary of some sort, separating the southern Sierra Nevada/Fremont Valley and the Antelope Valley, appears to be reflected in the archaeological record (Sutton 1989). This boundary is delineated by the presence of considerable obsidian, brownware ceramics, and Desert Side-Notched projectile points in the north with less obsidian, fewer ceramics, and predominantly Cottonwood Triangular points to the south (Sutton 1991:23). It has been suggested (Sutton 1991) that the relative decline in Coso obsidian importation and the appearance of both Desert Side-Notched points and Owens Valley Brown Ware and other ceramics may be locally associated with Numic population movements in some way connected to the socalled Numic expansion or spread out of southeastern California. Sutton suggests, as noted above, that the archaeological evidence for a possible Numic presence, as defined by ceramics and Desert Side-Notched points, is stronger for the northern portion of the western Mojave Desert and Antelope Valley environs than for valley areas further south. This argument has yet to be fully confirmed archaeologically. Archaeological Research Design for the Antelope Valley Study Area 264 07A3822 Task Order 17 Movement of Hokan-Speakers/Yuman-Speakers in the Mojave Desert It had formerly been presumed that the arrival of Uto-Aztecan speakers in coastal Southern California displaced populations of Hokan-speakers, who represented a more ancient language family in central and southern California. Historic groups such as the Salinan and Esselen located to the south and west of the Central Valley, and Yuman-speakers in southern and southeastern California, the lower Colorado River, and Western Arizona, are recognized as having derived from this ancient Hokan linguistic stock. Chumash was also formerly classified as Hokan, although it is currently classified as an ancient isolate. It had also been proposed that a quite widely distributed proto-Yuman language community was in place in coastal San Diego County and in interior deserts further north at or before 3000 BP (Foster 1996:86-87). Hale and Harris (1979:174) suggested that the inhabitants of the Mojave Desert that created the Pinto Basin Complex belonged to the Yuman branch of the Hokan language family. Under these scenarios, Yuman-speakers were thought to have migrated to the east at the time of their displacement by Uto-Aztecans, reaching the lower Colorado River in the vicinity of modern Mojave territory, and migrating southward between 3000 and 2000 BP. However, Golla (2011:248) has provided a very different scenario for the movement of Yumanspeaking populations. He proposes a maximum time depth for Yuman linguistic differentiation of 2,000 years. He believes that this group of languages originated in Northeastern Baja California, and that the differentiation of the Yuman languages and a corresponding movement up the Colorado River dates from circa AD 700-1000. He emphasizes that this late movement included a presence in the Coachella Valley and in the Mojave Desert, and thus interaction with Takic and Numic groups during the Late Period. He further states: The Coachella Valley and the adjacent Santa Rosa Mountains are likely to have been occupied by Yuman speakers before the Cahuilla and Cupeño entered this area from the north and west, and River Yuman influences on Serrano and Kitanemuk testified to the presence of early Mohave or Maricopa speakers in the Mojave Desert as far west as Antelope Valley and the Tehachapi Mountains (Golla 2011:248). This intriguing statement may be related to a series of facts that could account for the linguistic influence cited here without the implication of a substantial occupation of the Antelope Valley or the Tehachapi Mountains by the Mojave. In the first place, in protohistoric and historic times, young male Mojave long-distance trader/travelers constantly visited both the Antelope Valley and the Tehachapi region, while engaged in the conveyance of shell beads from the Southern California coast to the Colorado River. It is known, in addition, that the Mojave claim, according to their traditional historical accounts, to have had a group of Mojaves living on the upper Mojave River for a time (Kroeber 1951). This account may or may not be connected to other native testimony, Chemehuevi and Mojave, about groups of so-called Desert Mojave occupying the Providence Mountains, the Old Woman Mountains, the Sinks of the Mojave River, and other central Mojave Desert localities at some recent time, apparently prior to the 1770s. The Mojave of the Colorado River also recognized Double Archaeological Research Design for the Antelope Valley Study Area 265 07A3822 Task Order 17 Peak, Avi Hamoka, south of the Tehachapi Valley, as one of their most sacred places, and Rogers Dry Lake at Edwards AFB is also a Mojave sacred place (Earle 2009a). The last Desert Serrano inhabitants of the Mojave River area were captured by Mojaves, circa 18351840, and taken to the Colorado River before some of them later went to settle with linguisticallyrelated Kitanemuk-speakers living southwest of the Tehachapi Valley. Kroeber and Harrington were given hints about some connection between the Mojave and the Tejón/Tehachapi area, apparently linked to the Mojave captives who moved to the latter region. These hints may form part of the basis of Golla’s statement about a Mojave presence in the Antelope Valley and the Tehachapi area. However, the Mojaves constantly visited these areas in historic times, recognized sacred places in them, and were hosted by local villagers. Thus, it is possible that there may have been episodes of longer-term presence. While the Colorado River Mojaves followed a flood-farming regime not adaptable to the desert, the so-called Desert Mojaves were claimed to have adopted the buckskin dress and hunting techniques of the neighboring desert Chemehuevi. That settlements of such Desert Mojaves would thus be easy to differentiate archaeologically from local settlements is open to question. Population Movements Westward to the Mojave River - the Anasazi Golla (2007, 2011) notes the possibility of a re-contact between the eastern and western divisions of the Uto-Aztecans after around AD 500. This would correspond to the expansion of the Anasazi into southern Nevada and, as Golla notes, as far westward as Halloran Springs and Soda Lake in the Mojave Desert of California. Also, as previously stated, there is evidence for Anasazi occupation of the Cronise Lake area even further west along the lower Mojave River. Golla believes that this spread of the Anasazi to the west may have involved some cultural transmission of Southwestern or Anasazi cultural characteristics to Takic-speaking groups in Southern California. This is supported by evidence that shows the presence of Anasazi or Anasazi-like groups living in southern Nevada, mining turquoise at Halloran Springs east of the Sinks of the Mojave, and even of carrying out horticulture in the vicinity of the lower Mojave River at Cronise Lakes (Lyneis 1995). Spindle whorls for spinning cotton thread were recently recovered at the latter location, and it is known that maize farming was also carried out there. The Anasazi cultural presence has been detectable archaeologically because the material technologies used by this group have been so distinctive and different in comparison to those of desert foraging cultures. Nevertheless, this archaeological evidence may either represent an Anasazi presence or the presence of local groups that adopted Anasazi material culture traits. To this latter point, it is important to keep in mind that this area of eastern California including the lower Mojave River was an important prehistoric route of communication with Yuman groups on the river in later times and may have been very important as a route of exchange and cultural communication at this earlier time as well. Archaeological Research Design for the Antelope Valley Study Area 266 07A3822 Task Order 17 The Chemehuevi Diaspora A late population movement bearing on the Antelope Valley, itself, is the arrival of Chemehuevi groups (Numic speakers) from the northeast during the early and mid-nineteenth century. Earle (2004, 2005) has described Chemehuevi movements southward and westward from their late eighteenth-century homeland in the deserts to the northwest and southwest of Colorado River Mojave territory. Their settlement on portions of the Colorado River to the south of Mojave territory is well known. The characteristics of the migration of small bands as far as the southwestern Antelope Valley foothills, the San Gabriel Mountains, the Coachella Valley, Yuma, and San Diego County is less well known. By the late nineteenth century, their camps on the north and south side of the Antelope Valley, at Lovejoy Springs (CA-LAN-192), Barrel Springs, Indian Water, Harold Foothills, and elsewhere, were the last manifestations of a purely traditional native way of life in the valley. Nevertheless, the archeological analysis of one of these Chemehuevi camps did not yield strikingly different material culture remains, including projectile point types, than what would be expected inseasonal camps of Takic-speakers prior to their removal from the Valley to the Franciscan missions before 1820. Applying Mitochondrial DNA Data to the Study of the Migration of Takic Populations Eshleman and Smith (2007) presented information about research on mitochondrial DNA clades of California Native Americans. Among other issues, they discussed research with samples of ancient human remains from the California Channel Islands that aimed to identify whether clades associated with Chumash ancestors and those associated with other populations, presumably ancient Takic UtoAztecans could be clearly distinguished. That turned out to be the case. They discussed a sample population on San Clemente Island dating from about 3,000 years ago that was clearly distinct from ancient Chumash and shared some characteristics with modern Takic populations. This information hinted at the possibility of a relatively early Takic presence on the coast, although internal genetic diversity among Takic populations makes the identification of a standard set of characteristic haplogroups difficult. They also discuss a Takic genetic marker found among living Takic populations by Johnson and Lorenz (2006) and in a Late Period, presumably Takic, burial near Palmdale (Kemp et al. 2005). In regard to the cladistic diversity of Takic populations, they also caution that human linguistic and cultural attributes cannot be treated as identical to human genetic inheritance. In other words, not all people who are affiliated to a group of closely related languages are going to enjoy relative genetic homogeneity. Thus, the mitochondrial DNA research as an approach is helpful, but not conclusive in elucidating ancient population movements in this case. Archaeological Correlates for Population Movements of Distinct Language Groups Identification of "ethnic markers" – archaeological features that could permit the identification of distinct language-ethnic groups and their movements through time –obviously has to do with Archaeological Research Design for the Antelope Valley Study Area 267 07A3822 Task Order 17 parsing out culture-specific objects and practices from those that are widely shared between different language/culture groups. The ethnography and ethnohistory of native Southern California provides a guide to potentially culture-specific objects and practices that have existed in Late Prehistoric times. The concept of a Uto-Aztecan intrusion in southern California figures prominently in the archaeological literature for the region in several different manifestations. First, there is the concept of the so-called Shoshonean wedge that refers to the initial arrival on the southern California coast of “Shoshoneans” or Uto-Aztecans. True (1966:291) suggested an association between the development of acorn processing after around 4000 to 3000 BP and the first appearance of cremations in coastal northern San Diego County, on the one hand, and the arrival of Shoshoneans/Uto-Aztecans. This “wedge” was viewed as splitting the formerly contiguous Millingstone Horizon cultures of coastal southern California, the Oak Grove Millingstone to the north, and the La Jolla Millingstone to the south. This version of the Shoshonean arrival on the coast was dated from 1500 to 1200 BC (3500-3300 BP). This scenario was based in part on Chester King identifying shell beads from the Terminal Early Period and Phase I Middle Period associated with cremations in northern Takic areas—the territory of the modern Tataviam, Gabrielino, and northern Serrano (Moratto 1984:165). Thus, Moratto places the Uto-Aztecan arrival on the coast in the 35002500 BP range. A key assumption made here was that cremations were a hallmark of the culture of the Takicspeaking groups at the time of their arrival. This cannot be assumed for a number of reasons. Among these is the fact that while linguistic evidence has been presented to suggest that Serrano speakers and/or other Takic speakers have been present in the southern Antelope Valley region at least for the last 1,500 years or so, interments postdating that date occur in the area. It is noteworthy that historically Numic groups of the southern Great Basin frequently did not practice cremation, but rather interment. In addition, the practice of cremation among the Cahuilla and Serrano, and its religious justification, appear to have links to late prehistoric Yuman cultures of the lower Colorado River. A second model of the timing of the ‘Shoshonean wedge’ involves a late coastal arrival—after AD 500, or even much later—with cremations, pottery, and small triangular arrow points. In the San Luis Rey River drainage this “Shoshonean intrusion” is placed at circa AD 500-1400 (Moratto 1984:158,161-162). This concept of a late date for a Shoshonean arrival, coeval with or following the introduction of the bow and arrow, is reflected in the former use of the term Shoshoni for the Late Period (post-AD 1200) in some Mojave Desert archaeological chronologies. Warren (1984:423-424, 426), for example, had rejected Bettinger and Taylor’s (1974) late date for the Cottonwood Triangular series at post-AD 1300 and the arrival of Takic-speakers in southern California at approximately the same date. In general terms, the search for archaeological continuities and discontinuities in settlement and in economic and social activities can provide solid inference about population movements. An Archaeological Research Design for the Antelope Valley Study Area 268 07A3822 Task Order 17 interesting comparative test of archaeological continuity and discontinuity evaluation was carried out by Alan Garfinkel (2007) at the very southern end of the eastern Sierra, north of the Antelope and Fremont Valleys. He compared sets of sites that had been occupied by the ancestors of the historic Tubatulabal in the Kern Plateau area, with sites further east at the eastern base of the southern Sierra around and south of Ridgecrest. His hypothesis was that the ancestors of the Tubatulabal had been living in place for at least 3,000 years. Thus, he could expect to find archaeological continuity in site occupation, in cultural ecological adaptations, in material culture inventories, in ideology as expressed in rock art, and so on. He also hypothesized that the inhabitants of the desert floor and foothills at the eastern base of the Sierra had undergone a "turnover", previous inhabitants having been replaced by Numic-speakers who had expanded southward from a homeland north of the Coso Mountains during the Numic Expansion. Garfinkel presented archaeological data that appear to confirm that the Tubatulabal occupation of the Kern Plateau reflected long-term occupational and cultural continuity, with discontinuity further east on the desert margin. He presented information supporting the idea that there had been population movement and replacement through the arrival of Numic speakers. This study is of particular interest for the Antelope Valley region because the archaeological variables that he analyzed are to a considerable extent applicable to the Antelope Valley case. Other archaeological studies of movements of native population in California to new locations highlight the challenges inherent in archaeologically identifying population movements or migrations by language/cultural groups. Morgan (2006, 2010) has studied the late prehistoric movement of the Western Mono across the Sierra Nevada from the Owens River region to the San Joaquin Valley foothills. Morgan notes the presumption (Bettinger and Baumhoff 1982) that migration entails competition between groups. He was able to archaeologically reconstruct distinctive features of western Mono adaptation to their Sierra environment. He noted that the dispersed distribution of upland summer camps was ethnically distinctive. This included the use of small bedrock milling features at camps above 7,000 feet. In addition, the use of distinctive acorn caches, key to the western Mono subsistence system, was a marker of the group ethnic identity and territorial occupation. Details of basketmaking, which combined both Yokuts and Numic features, are also an ethnic marker. The production of both sinew-backed bows and snowshoes, that were traded to San Joaquin Valley groups were also distinctive group traits. Thus, both cultural landscape features and cultural artifacts existed that identified the presence of the group. But Morgan also pointed out that the western Mono had also borrowed cultural and technological features from their new neighbors. Their movement across the Sierra from the Great Basin to the Sierra Nevada and eastern margin of the San Joaquin Valley entailed a shift in economic adaptation and, thus, a shift in cultural organization. The generalization can be drawn that cultural landscape features can serve as ethnic markers for the presence or movement of cultural groups. Technology and material culture also serve as cultural markers, but in the California context these markers are very frequently perishable. This leads to a Archaeological Research Design for the Antelope Valley Study Area 269 07A3822 Task Order 17 dependence on a fairly narrow range of imperishable artifacts, or on the layout of sites, camps, and activity areas as cultural landscape features, as indicators of cultural affiliation. Summary Linguists have debated the location of the original homeland of proto-Uto-Aztecan speakers. Victor Golla and others have argued for a location in interior California and the Southwest. Golla has further developed a scenario for a divergence between proto-Takic and Proto-Numic elements of the UtoAztecan language family in interior California, with a proto-Numic homeland located between Mono and Owens Lakes, and a proto-Takic homeland in the Tehachapi Pass region. Golla dates the establishment of Proto-Takic speakers in the Tehachapi region, bordering the northwest edge of the Antelope Valley, as between 3,500 and 2,500 years ago. He views the diversification of Takic languages as requiring about 2,000 years, with Serrano emerging first as a distinctive language within the northern branch of this language group. The diversification of Southern Takic languages he treats as a rather more recent process, within the last 1,500- 1,000 years. The proposed Tehachapi Pass location for the initial development of the Takic language group suggests an early date - soon after 3,500-2,500 years ago - for occupation of the nearby Antelope Valley by Takic-speakers. Golla also suggests a recent movement of Yuman-speakers upstream on the Colorado River during the last 1500 years. In the context of a discussion of traditional scenarios for the presumed arrival of Uto-Aztecan speakers in Southern California, Golla's reconstructions of Uto-Aztecan language divergence suggest a significantly later occupation of more southerly and coastal areas than of the Western Mojave Desert. Scenarios for the 'Numic spread' after 1,000 BP and a related Numic arrival at the northern margin of the Antelope Valley, as opposed to an earlier Numic presence there, have also been discussed. This section also reviews evidence for the reach of Anasazi settlement and influence westward to the lower Mojave River at circa 1500 years ago, and historic-era movement of groups of Chemehuevis into the Antelope Valley itself. It also discusses several cases of identification of archaeological material culture ethnic markers that may be useful in reconstructing prehistoric population movements. In this section, the importance of historical linguistic scenarios has also been emphasized. Proposed historical linguistic reconstructions for the movement of prehistoric populations depend on both spatial and temporal inferences. These inferences should be validated with archaeological corroboration. Reconstructing the sequence of geographical locations for language groups in the past depends ultimately on applying scenarios of language divergence to modern linguistic geography. This involves applying conservative assumptions about the frequency and scope of group movements over time. In addition, the assumption of an identifiable and constant rate of language diversification is essential to reconstructions such as Golla's, and these assumptions continue to be controversial for linguists. The analysis of language diversification and of population movements, becomes more difficult as the prehistoric timescale extends further into the past. Golla's Archaeological Research Design for the Antelope Valley Study Area 270 07A3822 Task Order 17 reconstructions for Takic and Yuman language diversification emphasize the relative recency of these developments. These interpretations by linguists diverge from the ideas of some archaeologists and some Native Americans about the antiquity of occupation of historic-era ethnic group territories in Southern California. It has been suggested that certain cultural features reflected in the archaeological record may be used to distinguish areas of occupation for Takic, Numic, or Chumash native ethnic groups in the greater Antelope Valley region in the Late Prehistoric and Mission Periods. Suggested ethnic markers for different groups include projectile point types, use of ceramics and certain ceramic types, rock art styles, basketry styles, mortuary treatments, and relative use of certain shell bead types or of raw materials like obsidian. With respect to the presumed initial occupation of the Antelope Valley by Takic speakers at 3,000-2,500 years ago, archaeologists have assumed that the transition from the mobile foragers of the Pinto complex to a more sedentary village-based settlement system by the end of the Gypsum Period reflects the arrival of Takic speakers. Thus, the presence of cemeteries, of permanent dwellings similar to those found at CA-KER-303, of elaborate assemblages of shell bead mortuary offerings, the use of the portable mortar and pestle, the development of a steatite and schist craft industry, and production of ornaments, as well as ground stone implements, are possible markers of Takic-speaking populations. The timing of the appearance of these cultural characteristics requires more archaeological study. Research Questions and Data Needs Questions 1) Do the archaeological characteristics of contact period or protohistoric sites in the Antelope Valley differ between regions or putative ethnic territories? In other words, for the protohistoric period, does the proposed geographic distribution of ethnic territories within the Antelope Valley region appear to correspond to differences in archaeological characteristics of settlements occupied by different ethnic groups? These differences might include different characteristics of rock art, differences in mortuary customs, different subsistence regimes, differences in types of shell beads being used, or differences in chipped stone tool types or materials. 2) Do archaeological characteristics of specific sites indicate long-term continuity of prehistoric cultural practice, and possibly of ethnic occupation? Robinson (1987) proposed that Antelope Valley sites exhibited marked cultural continuity from circa 500 BC to protohistoric times. Thus, from the middle of the Gypsum Period onward, the archaeological record would reflect a continuity in cultural practices, possibly associated with Takicspeaking ethnic groups. Principal characteristics that would have continued through these time periods include hard seed processing with handstones and millingstones, rhyolite and obsidian chipped stone tools, use of circular thatched dwellings, the use of imported shell beads, basketry, the fabrication of steatite and schist artifacts, and the persistent practice of inhumation. The evaluation Archaeological Research Design for the Antelope Valley Study Area 271 07A3822 Task Order 17 of continuity in cultural practices would obviously be an important objective in analyzing archaeological data from stratified sites. 3) Can a characteristic set of archaeological cultural markers be associated with the presence of Takicspeakers as opposed to Numic-speakers in the Antelope Valley in the Late Holocene? Sutton (1989) suggested that the presence of Cottonwood series projectile points, relative absence of ceramics, and use of lithic materials other than obsidian would help to distinguish areas of occupation of the Antelope Valley by Takic-speakers during the Late Prehistoric Period. He believed, on the other hand, that Desert Side-Notched points, brownware ceramics, and an abundance of obsidian would characterize sites occupied by Numic-speakers. In addition, analysis of basketry remains and identification of Late Period distribution of pictographic and other rock art can clearly differentiate presence of Takic and Numic speaking populations. 4) Does the possible identification of sites or site components associated with Numic-speakers shed light on the antiquity of their presence in the Antelope Valley region, as well as on the relationship of their presence to the chronology of the Numic Expansion? The issues of where the Numic homeland may have been situated in relation to the Antelope Valley, and how long the Kawaiisu had been occupying the Tehachapi region, are relevant to the history of Numic presence on the north side of the Antelope Valley. Alternative scenarios have been suggested for the Numic presence, including the presence of the ancestors of the Kawaiisu in the Tehachapis long before the Numic Expansion, or a later Numic arrival in the northern Antelope Valley at the time of the Numic Expansion (circa AD 1000). 5) Will the analysis of prehistoric mortuary practices in the Antelope Valley shed light on continuity or change in the relative distribution of ethnic groups? The attribution of both cremation and inhumation to Numic groups creates a confused picture about their mortuary customs, both ethnohistorically and prehistorically. In addition, the frequent presumption by archaeologists that Takic-speaking groups universally practiced cremation can be questioned. Some Takic groups, like those resident on the Pacific coast of Los Angeles County, practiced both cremation and inhumation. The interpretation of mortuary behavior in the Antelope Valley context presents a number of difficulties, but it also suggests some degree of continuity in the practice of inhumation, including by desert Serrano groups. 6) Can the characteristics of settlements in the southern Antelope Valley in the late Gypsum Period be treated as markers for the arrival of Takic-speakers? The presence at Antelope Valley sites of cemeteries and of permanent dwellings; the presence of elaborate assemblages of shell bead mortuary offerings; the use of the portable mortar and pestle; the development of a steatite and schist craft industry, producing ornaments as well as ground stone implements; and a significantly increased use and exchange of shell beads, are possible cultural markers for the arrival and establishment of Takic-speakers in the region. In addition, evidence of the utilization not only of acorns, associated with use of the mortar and pestle, but of mesquite and Archaeological Research Design for the Antelope Valley Study Area 272 07A3822 Task Order 17 juniper berries, would possibly signal a shift to a broader diet associated with the presence of more sedentary Takic populations. Mesquite processing is indicated by distinctively shaped stone pestles used with wooden mortars. Carbonized juniper berries are found frequently in Antelope Valley habitation sites with developed midden. These cultural characteristics are associated with habitation sites whose initial occupations appear to date to around 2,500 years ago. The appearance of these cultural features 2,500 years ago matches the time of the expansion of Takic speakers from the Southern Sierra through the southern Antelope Valley proposed by linguists. However, radiocarbon dating from archaeological investigations of sites with these proposed Takic cultural markers is needed to determine when these characteristics first appear in the southern Antelope Valley or in other regions of the valley. Data Needs Future archaeological research, including survey of archaeological landscapes and testing of sites using appropriate sampling strategies, should address the following data needs related to continuity or change in the ethnic/cultural affiliation of sites in the Antelope Valley region. • Analysis of both chipped stone and ground stone assemblages to identify continuity or change in tool type raw material, form, and function, including projectile points and ground stone food-processing tools. • Analysis of ceramics, including clay composition and source, form and decoration, and possible origin. • Analysis of the origin, form, and possible date range of shell beads, and analysis of form of schist and other stone beads and their temporal context. • Analysis of composition of plant and animal remains, and plant and animal processing tools, as noted above, indicating shifts in environmental adaptation related to population movements. • Identification of shifts in the frequency of imported items like asphaltum and mineral pigments. • Recovery of remains of basketry - including fragments preserved by charring, coating with asphalt, or caching in sheltered locations - providing useful information on cultural/ethnic identity. • Radiocarbon dating of shallow site deposits and site components of stratified sites. • Analysis of indicators of culturally distinct mortuary customs. • Identification of the distribution of both pictographic and petroglyphic rock art. • Analysis of assemblages of different classes of artifacts would permit quantitative intra-site temporal comparisons and comparisons between sites. Archaeological Research Design for the Antelope Valley Study Area 273 07A3822 Task Order 17 Theme: Social Differentiation The anthropological and archaeological literature, and consequent theoretical underpinnings, on mortuary practices and/or social differentiation in ancient societies is extensive and varied. This chapter, however, focuses specifically on the issue of mortuary analyses and the interpretation of associated shell beads as markers of social differentiation, particularly of social status. This narrow focus is deemed necessary in order to critically assess the validity of the repeated (and what appears to be exclusive) application of such an approach to mortuary studies in southern California. Mortuary Features and Associated Funerary Items: Cases from the Antelope Valley Several cases of inhumations involving significant quantities of mortuary goods, including shell beads, have been reported for the Antelope Valley region. These include human remains from cemetery contexts at five sites and two isolated burials at two additional sites in the Antelope Valley (Robinson 1987, Sutton 1988b:50-61). All of these were inhumations. As with cemetery contexts elsewhere in southern California, there is a contrast between typical inhumations featuring few or no accompanying grave goods, and a minority of cases where individuals, including females, children, and infants, are accompanied by large quantities of what might be called bead wealth. At CA-LAN-192 (Lovejoy Springs), five individuals, four adults and a child aged 6-8, were apparently buried together in a cemetery area. A double loop necklace of 2,135 Olivella saddle beads or tiny disc beads was placed around the neck of the child. The beads were likely accumulated (before being strung into a necklace and placed on the child) over time because some of the beads appeared to have been freshly drilled, while others had indications of string grooves worn in the center of the beads. The child had also been partially covered by a 10-string shroud composed of 1,101 spirelopped Olivella shells. An inverted milling slab was found with this burial group, but shell beads were not associated with the adults. Radiocarbon dating of human remains from this mass burial yielded the date of circa 2,700 BP. An adult male skeleton in this mass burial had a dart point characteristic of the Gypsum period embedded in one of its ribs. These date attributions for the mass burial were used to support the contention that CA-LAN-192 possessed a cemetery and was occupied as a village site during the Gypsum Period. Another site, CA-LAN-488, on the southwest margin of the Antelope Valley, contained a 3 m deep midden deposit. A radiocarbon date midway down in this deposit yielded a date of 770 +/- 90 BP (Sutton 1988b:55). Four burials were recovered during excavations at the site in 1969-1970. The burials of two adults and a child yielded only a few associated artifacts. The fourth burial was of an infant, and it contained over 5,000 tiny beads which were recovered using 1/16th inch screen. At CA-KER-303, an extensive village site on the northwest side of the Antelope Valley, a cemetery was excavated that had previously been vandalized (Sutton 1988b:58-60). Over 30 burials were recovered through controlled excavation, and the cemetery is believed to have contained a much Archaeological Research Design for the Antelope Valley Study Area 274 07A3822 Task Order 17 larger number of individuals. Excavation of the site also yielded the remains of three dwelling structures, which dated to the late Gypsum Period. One group burial yielded a flint-knapping kit. One unusual burial (Burial 24) included an adult female interred with her head down and her hips up. In addition, her legs had been severed at the knees and placed on top of her body. This burial was accompanied by a total of 1,526 Mytilus disc beads, 1,055 Olivella disc beads, 32 complete and 13 fragmentary Megathura [limpet] rings, 6 Haliotis ornaments, and 3 steatite beads. An isolated burial was also reported by Sutton (1988:60) that was found in the foothills of the Tehachapi Mountains on the northwestern edge of the Antelope Valley. The burial contained a middle-aged male with several strands of beads, including 886 Olivella wall disc beads, and a second strand of 236 beads of Mytilus, Tivela, Haliotis, Olivella, Columella, and stone. Shell Beads as Status Markers in Southern California The occurrences described above of notable differences in the quantity and quality of shell beads and other grave goods accompanying inhumations has been noted for various prehistoric cemeteries excavated in southern California, and have been attributed by some researchers to social differentiation within hunter-gatherer societies. Cemeteries in the Channel Islands have yielded infant and child inhumations. Arnold (1987:234-235), for example, described a late-period burial from CA-SRI-2, apparently the Santa Rosa Island village of Niaqla, where large quantities of tools and shell materials of bead-making specialists were interred with a six-year-old child (Rick et al. 2004). This settlement was part of a region in the northern Channel Islands where shell beads were produced by specialists (Arnold and Graesch 2001). Linda King (1969, 1983) analyzed the Medea Creek Cemetery in the territory of the Ventureño Chumash in order to investigate Chumash social organization. This was attempted, in part, based on the analysis of the type, quantity, quality, spatial distribution, and accompanying burial characteristics of shell bead lots found in the cemetery. It was concluded that the distribution of bead ‘wealth’ in the cemetery supported the idea that Chumash society was ranked or stratified in terms of differences in wealth and social status. More recently, Gamble et al. (2001) analyzed another Chumash cemetery at Malibu State Park. They also emphasized the concept of Chumash mortuary behavior reflecting the existence of a wealthy hereditary elite; an elite in both the sociopolitical and the economic senses of the word. Membership in this elite class was viewed as an ascribed status, inherited through membership in high-status kinship groups. The ascribed status of membership in such a group was contrasted with the kind of achieved status and achieved wealth associated with Big Men, where wealth and political power were not inherited. Gamble et al. described a distribution of funerary goods at the cemetery where some men, women, and children were accompanied by considerable funerary goods or offerings, often including shell Archaeological Research Design for the Antelope Valley Study Area 275 07A3822 Task Order 17 beads as well as fragments of plank canoes. Other individuals interred in the cemetery, accounting for the majority of burials, lacked this array of funerary goods. It was thus concluded that this inequality in funerary furnishings reflected a social and economic inequality in Chumash society that these researchers claimed had been ethnographically documented. For them, a key aspect of funerary behavior was the provision of elaborate funerary furnishings to females and also to children and young children. Their argument was that only with the existence of elite kin groups inheriting wealth and social position would females and especially young children have been provided with unusual quantities of grave goods. The investment of valuables in the funerary furnishings of young children in this case would be seen as a symbolic re-assertion of the prestige and authority of the elite kin groups to which the children belonged. Cannon (2016) has discussed the occurrence of shell beads at sites excavated as part of the Playa del Rey project, focusing especially on mortuary contexts. She compared the Playa del Rey project mortuary bead data for Gabrielino/ Tongva burials with those from cemetery contexts at several other sites in southern California, including the Malibu and Medea Creek cemeteries discussed by Gamble et al (2001). She also discussed a cemetery at the protohistoric Gabrielino/ Tongva village of Yaangnaˀ, near downtown Los Angeles (Goldberg 1999). At CA-LAN-62 at Playa del Rey, as at Malibu and Medea Creek, there were a minority of burials that contained much larger than average quantities of shell beads. This was not the case at the Yaangnaˀ cemetery, where interred beads were limited in quantity or absent for the range of burials recovered. The cemetery or burial ground excavated at CA-LAN-62, within the Playa del Rey Project area, included 307 burial features, many of which contained the remains of multiple individuals. The majority of the burials appeared to postdate 1769, although a number appeared to date from the Late or Proto-Historic Periods. Thus, inhumation rather than cremation was clearly practiced there prehistorically. A slight relative tendency was observed for infants and young children to have a greater frequency of large bead inventories in their burials than other age groups. It was reported that a small minority of burials had very abundant bead inventories- over 1,000 beads. In contrast to what was proposed for Medea Creek - that large burial lots of beads were restricted to a few typeslarge bead inventories found with inhumations at CA-LAN-62 were not limited to a narrow range of bead types. In addition, Chester King (1990) had hypothesized for the Medea Creek cemetery that high-value beads would be found mostly in elaborate or high-status burials. However, the analysis of burials and associated beads from CA-LAN-62 showed that this was not the case. High-value beads were relatively widely distributed among all burial types. In contrast, high-value shell beads do appear to be a marker for high status burials in coastal Gabrielino/Tongva cemeteries (Reddy et al. 2016). For both prehistoric Southern California, and California in general, archaeological evidence of "wealth"- its generation, its retention, and its display and prestation, especially in ritual settings, presents problems of interpretation. As previously noted, Gamble et al. (2001) believe that among the Chumash a hereditary economic and political elite retained wealth over many generations, in part through plank canoe ownership. However, in other foraging societies of California, the accumulation Archaeological Research Design for the Antelope Valley Study Area 276 07A3822 Task Order 17 of goods as wealth and the development of political elites were often constrained by social and cultural practices that discouraged the inter-generational retention of wealth. Important here was the widespread practice in California of destruction or disposal of property of the dead at funerals, wakes, and the periodic community mourning ceremonies. Some Chumash researchers have followed Chester King's (1990) argument that such destruction promoted economic and social stability by restricting the supply of valued goods like shell beads. The native California ethnographic record attests to various stages of a process of ‘ramping up’ of productive activities, including both food procurement and craft production, in part related to both destruction of goods and their prestation in the context of the annual and longer-term cycles of religious fiestas. Such a scenario has sometimes been referred to as the ritual mode of production, where household production is increased to underwrite the hosting of religious ceremonies and fiestas (Earle 2017, Spielmann 2002). This hosting involved ritual display and generosity to guests, as well as the maintenance of economic and political alliances between host and guest groups. Important in this social and religious context is the idea of disposal of wealth through gift or destruction as a conversion of wealth into prestige and alliance maintenance, rather than retention of material wealth over generations. Coastal Chumash communities that were dependent on marine resources, which supported populations of as many as 700 people or more, were among the most productive in California with respect to both food supply and craft goods. Nevertheless, while Harrington’ ethnographic information, especially from Fernando Librado, suggested the existence of political and religious elites among the Chumash, it is not clear to what extent these elites were based on a continuous generation and conspicuous disposal, circulation, or destruction of wealth, including ritual generosity, as opposed to long-term multi-generational retention of wealth, including bead wealth, through inheritance. It is also not clear whether inheritance was based on truly unilineal descent groups. Gamble (2007:55), for example, has indicated that our data on the actual organization of Chumash descent groups is limited. At issue here is the relative importance of accumulated wealth per se, as opposed to the occupation of political and economic ‘offices’ that themselves would have been inherited and that generated both economic wealth to be circulated and political and religious authority. Mortuary Practices and Social Differentiation in the Antelope Valley For the Antelope Valley, the ethnographic record on native mortuary customs and practices includes cremation and inhumation. The mountain Serrano arereported to have practiced cremation in protohistoric times. The Desert Serrano are believed to have also practiced cremation, although Benedict (1925) was told that only inhumation had been practiced since the early 19th century (Strong 1929:32). Kitanemuk consultants reported having practiced inhumation and to have used grave poles. These practices are similar to those of the Chumash and the Kastiq Chumash of the Castac Lake region were immediate southern neighbors of the Kitanemuk. Neighboring Southern Valley Archaeological Research Design for the Antelope Valley Study Area 277 07A3822 Task Order 17 Yokuts groups also practiced inhumation. The Kawaiisu and Chemehuevi are also believed to have practiced inhumation (Earle 2004, 2009). In the case of the Kitanemuk, we know that chiefs were accorded special treatment, including the use of grave poles, in their burials. These groups were not, however, described by native consultants or by ethnohistorical accounts as possessing a distinctive sociopolitical elite rank or class. In the case of the Mountain Serrano, cremation was associated with a funeral ceremony and mortuary ceremonies that involved destruction of personal property through burning. Such burning would usually include, for adult males at least, the house of the deceased, which was a widespread practice in southern California. This was followed by a periodic mourning ceremony commemorating all of the deaths of community members that had occurred since the last mourning ceremony. This ceremony was intended to provide an opportunity for the destruction of the remaining personal property of the deceased. In addition, kinfolk of the deceased would often contribute additional items of value to be destroyed - basketry or beads, for example - as an expression of their mourning. There may have been an element of status rivalry in the amassing of valuables for destruction by mourning families. Sometimes such items were reportedly given away rather than being destroyed. These cultural practices tended to limit the accumulation of inheritable wealth over generations within families or by chiefly family lines. Burial Treatment: Occurences of Inhumation and Cremation The mortuary practices reported for a number of Antelope Valley sites suggest that inhumation was practiced from Gypsum Period times or before until a relatively late date in the Antelope Valley. The implications of this regarding possible changes in ethnic affiliation of populations in the valley is unclear because of the assumption that Takic language affiliation groups had exclusively cremated their dead from the time of their arrival in Southern California. However, this assumption does not appear to be substantiated by the archaeological evidence. The assumption that Takic people cremated is based on Chester King’s proposition that cemeteries containing cremated remains came to predominate in historically Takic-speaking areas of Southern California after circa 1000 BC (King and Blackburn 1978:535). He has elsewhere dated this efflorescence of cremation among the Gabrielino at circa 700-500 BC (King 1994). Even at the time of Spanish contact, the practice of cremation appears to have been much more strongly established in interior southern California, as among the Cahuilla, for example, than among the Gabrielino, closer to the Pacific coast. Gamble and Russell (2002:118-124) provide an overview of thirteen cemetery sites in western Los Angeles County in Gabrielino territory mostly dating to the last 2,500 years. Nine sites reportedly contained both inhumations and cremations, three had inhumations only, and one had cremations only. Gamble and Russell note the relative distribution of inhumation and cremation in the region as complex. Cannon’s (2016) analysis for Playa Vista on the Los Angeles County coast also suggests the continued importance of inhumation there. Archaeological Research Design for the Antelope Valley Study Area 278 07A3822 Task Order 17 Mortuary Offerings The ethnographic record for southern California for Takic groups is not especially helpful in interpreting the social meaning of significant differences in mortuary goods in interments. For the Gabrielino/ Tongva we do have statements suggesting that traditionally it was desired to place some valued goods in the graves of the deceased, and that chiefs and shamans were interred with the largest quantities of grave goods (Geiger and Meighan 1976:97, McCawley 1996:157, Reid:1968:31). It can be concluded, as Cannon did, that in that social context some individuals or families were more capable of amassing and investing mortuary bead ‘wealth’ than others. But we can ask whether some ritual or mortuary displays involve a daunting sacrifice of property for the sake of either prestige or some valued religious objective rather than an affirmation of inherited status and wealth. In other words, there was likely an investment in mortuary goods independent of elite status. Binford (1971), T. King (1970), and others proposed that the presence of presumed status markers such as shell bead wealth with juvenile or infant burials would mark membership in a hereditary elite. Milliken and Baumhoff (2007:334-336) noted that objections had been made to this presumption, and alternative scenarios were proposed where non-elite groups would ‘invest’ in burial goods for juveniles and infants. They noted that only where a tiny minority of burials displayed great wealth could ascribed status be assumed. They assembled grave goods data on 46 sites in central California, finding that the percentage of burials collectively containing at least 90% of all cemetery bead wealth increased from four percent in the Early Middle Period to 20% in the second phase of the Late Period. In other words, the trend was for less concentration of wealth over time, rather than more. This ran counter to the presumption of a markedly increased concentration of bead wealth and social hierarchy over time. They also noted a surprising lack of difference between the total average size of juvenile and adult male mortuary bead lots, varying between approximately 1:2 and 1:1 (Milliken and Baumhoff 2007:334-336). As discussed earlier, southern California cases where 'ascribed status' burials, like those of juveniles and infants, appear associated with families or groups that were craft specialists. Arnold's (1987) bead-maker child burial is of that type. The bead-rich burials associated with canoe parts discussed by Gamble et al. (2001) can be argued as reflecting both economic specialization and elite social status. However, in the case of the Antelope Valley inhumations, it does not seem especially plausible to assume that ’wealthy’ child or infant burials are a sign that a separate economic elite class existed in a community of 60-100 foragers 2,000 years ago. We could alternatively propose that such mortuary treatment a) reflected economic specialization, as in regional bead exchange by a family group, b) reflected the political and ritual ascribed status of village hereditary chiefs, a status supported by the entire community, or c) reflected a major long-term effort by a particular non-chiefly family group to amass bead wealth for ritual purposes. The fact that, under either scenario, the amassing of such wealth was possible appears to be an indicator of a more sedentary village-based way of life. It also suggests that bead trading specialists and even hereditary chiefs may have been involved as Archaeological Research Design for the Antelope Valley Study Area 279 07A3822 Task Order 17 intermediaries in long-distance bead exchange from the southern California coast to the Southwest and the Great Basin. Earle (2005:12-17) has described, for the proto-historic period, the involvement of Mojave River Serrano chiefs in this kind of long-distance shell bead exchange. This allowed them to accumulate large quantities of beads that were used by them for ritual displays. Thus, even in communities with relatively small populations, the existence of hereditary political leadership based on descent could account for marked differences in mortuary wealth without the creation of a separate economic elite class. Research Questions and Data Needs Questions 1) Does the relative distribution of inhumations within or between sites during specific prehistoric time periods suggest differences in mortuary treatment (inhumation versus cremation, for example) due to a) occupation of different sites by different ethnic/groups, or b) occurrence of different mortuary practices for different categories of people within a given ethnic/cultural group? The relative occurrence of inhumation as opposed to cremation at sites within the region occupied by Takic-speakers in the protohistoric presents a rather complex picture. For example, some cemetery contexts attributed to the Gabrielino/Tongva involve inhumations rather than the cremations that some researchers might have anticipated from the ethnographic record. In the Antelope Valley, for the protohistoric period, it might be anticipated that some groups (Desert Serrano) practiced cremation and others (Kitanemuk) inhumation. Nevertheless, unless the arrival of the ancestors of the modern Serrano divisions - Mountain and Desert- in their respective areas of occupation was really recent, it is possible that cremation was not in fact an ancestral cultural marker for the Serrano. Inhumations are documented for the southern portion of the Antelope Valley with dates within the last thousand years. Thus, in evaluating what inhumations and their mortuary goods, including shell beads, can tell us about prehistoric social organization, we first have to consider how this particular mortuary practice fits into the bigger picture of treatment of the dead. Was the practice of inhumation in fact a cultural/ ethnic marker for specific groups and communities, or did different kinds of people receive different kinds of mortuary treatment? There are examples within the prehistoric Western United States where some people were subjected to inhumation and others were cremated within a given cultural group. For Numic groups, there are reports of inhumation as a standard practice, with cremation reserved for disposal of the bodies of witches or sorcerers. In other words, was the very fact of the use of inhumation, as opposed to cremation, a statement about the social status of the individual? Key in this regard is the identification of cases where inhumation and cremation appear to be practiced in the same communities during roughly contemporaneous time periods. 2) In analyzing the distribution of mortuary goods with specific inhumations, what evidence do we find that bead wealth is unevenly distributed in the cemetery population, and, if so, is that uneven distribution spatially organized within the cemetery? Archaeological Research Design for the Antelope Valley Study Area 280 07A3822 Task Order 17 As we have noted in our discussion of the analysis of native cemeteries in southern California, this is a fundamental question that investigators have posed. The characteristics of this uneven distribution include the degree of clustering of bead wealth among a relative minority of the population, and whether differences in distribution of wealth apply to the complete range of age and sex characteristics of the cemetery population. In other words, if we have a difference in bead wealth distribution among adult males, does this difference also apply to adult females, as well as juveniles and infants? Differential distribution suggests, of course, differential behavior by families of the deceased, if everyone has not been treated the same. Interpretation of this differential behavior is referred to in another question below. Analyses of differences in mortuary wealth in Southern California have usually attempted to determine whether burials containing abundant mortuary goods have tended to spatially cluster in certain parts of the cemetery. It is argued that such clustering would be a strong indicator of differences in social and economic status within the cemetery population. Obviously, the evaluation of both the distribution of bead wealth between different categories of burials and its spatial distribution in cemeteries is constrained in its significance by small sample size. 3) In analyzing bead wealth in mortuary contexts, can we determine whether it expresses elite status, reflected in immediate access to large lots of beads, on the one hand, or a gradual economic accumulation for ritual purposes by non-elites, on the other? A differential distribution of such wealth between individual burials could possibly reflect one of several scenarios. First, the capacity of 'wealthy' or 'elite' members of a community to routinely provide such mortuary goods, and their willingness to do so as an affirmation of their long-term elite economic/social standing. Second, the willingness of individuals or groups, not necessarily of elite economic status, to make an effort, even involving economic sacrifice, to provide substantial bead wealth or other mortuary goods. This effort would reflect a particular desire to honor the deceased, and thus also accrue associated prestige. Differentiating between these two scenarios archaeologically presents obvious difficulties. However, two lines of investigation that have been used in the past are relevant here. The first is the analysis of the characteristics of individual shell beads and classes of beads found as grave goods. Gamble et al. (2001) have argued that such shell bead assemblages that originate with elite families would reflect their procurement in large lots at one time from the fabricators. We could think of this as mass acquisition of bead lots. In contrast, we do have some ethnographic accounts of non-elite individuals saving up bead wealth and other items of value over long periods of time for use as mortuary goods. The concept here is that the items were not acquired as a lot, but painstakingly accumulated over many years, often reflecting previous use wear as well as greater variation in bead types, given the more fortuitous nature of their having been collected. Second, it would appear more probable that cases of the second type - long-term accumulation of wealth by non-elites for mortuary purposes - would be associated with adults rather than juveniles and infants. This would particularly appear to be the case given that in ethnographic descriptions of Archaeological Research Design for the Antelope Valley Study Area 281 07A3822 Task Order 17 this kind of long-term accumulation, adult males and females play a prominent role in promoting this accumulation for their own funerals. Thus, it is more clearly associated with adults. Infant burials associated with prominent bead wealth would appear less likely to have resulted from a long-term process of setting aside of bead wealth by non-elite people or families, and more likely to be associated with short-notice provision by families with more immediate access to wealth. In addition, King (1990) argued that bead wealth associated with elite groups should contain types of beads that were the most valuable in respect to the difficulty of their fabrication or in terms of their attractiveness as ornaments. Whether such apparently high value bead types can be identified as associated with conspicuously large bead assemblages (possibly indicating elite status) or whether they are broadly distributed as a mortuary good should be checked as part of a grave goods analysis. 4) What variations in the characteristics of bead wealth can be identified between different prehistoric time periods? Both within and between cemeteries, comparison of mortuary bead characteristics between inhumations dating from different time periods would shed light on the postulated development of social differentiation. The temporal data comparisons of Milliken and Baumhoff (2007) discussed above provide examples of this. They pointed out that such comparisons are constrained by sample size, since this requires a set of sufficiently large burial lots dating from different time periods. 5) In the Antelope Valley context, is there evidence of political elites (chiefs) or specialists like bead traders accessing bead wealth on account of long-distance exchange networks? In the case of the Antelope Valley, the availability of shell beads may have been enhanced by the area’s position as a link in long-distance exchange networks for shell beads, as previously discussed. A comparison of the quantities and types of shell beads from different time periods recovered at Antelope Valley sites, as compared with other regions of central and southern California, could illuminate the potential role that such exchange circuits played in increasing the availability of beads for mortuary use, especially by chiefs. Data Needs Any archaeological analysis of native human remains requires the approval and involvement of affected native communities and nations. Archaeological disturbance of human remains and burial contexts can be anticipated as occurring when no feasible alternative exists, and only after consultation with affected native parties. Thus, such work can be considered essentially of an emergency nature. In the event that such an archaeological contingency may arise, the research issues raised above regarding the interpretation of shell bead mortuary goods may be helpful in dealing with the resulting analytical tasks. However, other theoretical orientations should also be considered, particularly (and most importantly) approaches that incorporate perspectives from affected Native American communities. Archaeological Research Design for the Antelope Valley Study Area 282 07A3822 Task Order 17 Theme: Rock Art in the Antelope Valley Study Area Rock Art Types and Styles The concept of Native Californian rock art as a category of cultural or archaeological resources has been influenced by Euro-American ideas and cultural traditions regarding ‘artistic expression’ in painted or sculpted form. This characterization of rock art does not necessarily take into account a range of specifically Native Californian cultural/religious elements that might share either the outdoor landscape setting of rock art or its figurative or other symbolic features. These other elements, along with rock art itself, formed an interconnected sacred symbolic vocabulary for native religious ideas and ritual. These other elements included rock formations with visual features linked to supernatural events, ‘bell rocks’ used to create ritual sounds during ceremonies, caves used as offering and prayer shrines, and rock features related to solar observations. The creation of symbols, designs, or figures associated with rock art, was also found in other contexts, such as ritual face painting and sand paintings used as part of community rituals, for example, as described by Fr. Boscana for the Juaneño/Luiseño (Boscana 1933:38, 46). Rock art and rock art sites are important to Native Californians as expressions of native culture and religion and have been considered by them to be sacred places. California archaeologists have attempted to construct chronological frameworks for the temporal placement of rock art and interpretive frameworks for understanding its purpose in native culture. Analyses of both chronology and function have presented difficulties for some classes of rock art, especially rock art types not clearly associated ethnographically with late prehistoric native cultures. One prominent approach to the study of rock art in native North America and Native California has been to interpret rock art as the creation of ritual specialists or shamans transacting with the supernatural realm at locations removed from everyday activities. This shamanic practice has sometimes been viewed as involving personal pursuits of supernatural power, possibly involving altered states of consciousness such as shamanic trances (Whitley 2000). Thus, a fundamental question is posed as to whether specific types and cases of Native Californian rock art may reflect such personal shamanic activity as opposed to community ritual. The interpretation of native rock art in Southern California has been shaped by the fundamental differences between the archaeological and cultural contexts of painted pictographic and carved petroglyph rock art. Pictographic rock art was frequently created in relatively unsheltered locales, where its survival was likely to be relatively limited due to natural processes of weathering. Petroglyphic rock art in Southern California has tended to be much more durable, surviving in some places for many millennia. Thus, much of the surviving pictographic rock art of relatively recent date could be studied and appreciated in the context of living native cultural traditions and modern ethnographic information. Petroglyphic rock art present a greater challenge in understanding its Archaeological Research Design for the Antelope Valley Study Area 283 07A3822 Task Order 17 native cultural and religious context given the frequent linkage of such rock art with native groups occupying territories in Southern California as early as 5,000 or 6,000 years ago or more. The study of native rock art, including pictographs, petroglyphs, and cupules, in southern California, received considerable impetus in the late 1960s and early 1970s with the work of Campbell Grant, Robert Heizer, and Ken Hedges. Grant pioneered the systematic study of the polychrome pictographs of Chumash-speaking groups (Grant 1965). Heizer attempted a statewide survey of California rock art genres and styles (Heizer and Clewlow 1973) and defined a pictographic stylistic type - the Southern Sierra Curvilinear Style - that included interior Chumash, Yokuts, and other local styles. Ken Hedges, who headed a rock art research effort at the Museum of Man in San Diego, defined the so-called Southern California Rectilinear Abstract Style, a pictographic style believed to have been widely found among Takic-speaking groups such as the Serrano, Cahuilla, Gabrielino, and Luiseño (Hedges 1973). The Southern Sierra Curvilinear and Southern California Rectilinear Style classifications, as originally defined, generated some controversy as additional rock art sites were subsequently recorded. As knowledge of the full range of variation of southern California rock art grew, the original typologies were questioned, given the frequent presence of additional motifs. Thus, for example, it has been questioned whether pictographs from sites in protohistoric Gabrielino and Fernandeño territory are expressions of the Southern California Rectilinear Abstract Style (Knight 1993). Variations and inconsistencies could also be found in the Southern Sierra style, possibly attributable to differences between motifs and style used by different language groups in the region. Early stylistic comparisons were made as a mode of archaeological research without reference to ethnographic information about both pictographs and petroglyphs in Southern California collected by ethnographers which were not widely available to archaeologists and rock art researchers in the 1960s and 1970s. More recently, access to the field notes of John P. Harrington, Carobeth Laird, and Isabel Kelly, for example, has provided information about native religion, sacred places, rock art sites, and the creation of rock art in southern California. Rock art researchers sometimes encountered pictographic rock art sites located in places remote from native settlement and cited ethnographic information that suggested that these places were used as ritual locations which may have included the creation of rock art and the performing of astronomical observations by shamans. Thus, an interpretation of rock art sites as places for the deployment of esoteric knowledge and ceremonial by shamans developed. This focus included the interpretation of rock art motifs themselves as reflecting altered states of consciousness on the part of shamans or ritual specialists. It is possible that the more frequent long-term survival of pictographic rock art in cave sites that were sometimes spatially removed from native villages helped to stimulate the perception that painted rock art was usually found in remote and esoteric settings commanded by individual shamans. Ethnographic information for Southern California Takic language groups suggests, on the other hand, that a frequent setting for the creation of rock art was community initiation ceremonies Archaeological Research Design for the Antelope Valley Study Area 284 07A3822 Task Order 17 that were held in or near villages. The rock art associated with these ceremonies was often created on unsheltered rock surfaces, and was thus, from an archaeological standpoint, extremely impermanent. These possibly different cultural contexts for the creation of rock art are considered below in a review of currently available information about rock art in the Antelope Valley region. Pictographic Rock Art Styles and Culture in the Antelope Valley Region Ethnographic information about the religious and cultural context of rock art in Southern California suggests that several different pictographic rock art configurations and cultural traditions may have been found in different areas of the Antelope Valley. As noted previously, two major types of pictographic rock art in the region have been referred to as the Southern California Rectilinear Style and the Southern Sierra Curvilinear Style. The Southern California Rectilinear Style has been associated with southern California Takic groups. This is due not only to its late date and geographical distribution, but also on account of direct ethnographic testimony about this pictographic style. The Southern Sierra Curvilinear Style appears to have been related to an inland expression of a rock art style that originated among a number of Chumash language groups in south-central California. The two styles are quite distinct, and both styles are found within the Antelope Valley. Rock Art Traditions of Takic Groups A number of ethnographic sources for Takic language groups refer to the creation of pictographs as part of the ceremonial cycles of both male and female initiation. This is most fully documented in the case of the Luiseño, although there are also ethnographic references to females creating rock art as part of initiation ceremonies among the Cahuilla and Serrano. Luiseño initiation of boys into adulthood involved the drinking of a toloache or Jimson weed decoction, followed by ritual dancing, passage through a special ritual sand painting on the ground, and the imparting of instructions from elders. After further ritual activity, Du Bois (1908) states that the boys raced to a designated rock to create paintings. This was followed by an ant ordeal, which involved the initiate being covered by biting ants. After this ordeal was completed, the initiates passed through another sand painting. So-called 'bell rocks', large rock masses that rang or resounded when struck by a percussion rock, were then struck as songs were sung. Then the male initiates raced to nearby rocks, where the winner would paint a rock face with red and black paint. Female initiation involved being placed in a special pit with plant matting and warm rocks for several days. At the conclusion of the initiation ceremony, their faces were painted. Either at this point or a month later the face was painted with a particular geometric design, and the girls or adults painted corresponding designs on rock faces located near to the native settlements. Luiseño consultants provided the following information to Sparkman (1908): Archaeological Research Design for the Antelope Valley Study Area 285 07A3822 Task Order 17 At the conclusion of the period during which the girl remained in the pit, her face was painted, and a similar painting was also made on a rock. At the end of a month the girl's face was painted in a different manner, and a similar painting was added to the first painting made on the rock. This was repeated every month for a year, each month a different painting being placed on the girl's face, and a similar one added to the original one on the rock (Sparkman 1908:225). Kroeber (1908:174-176) noted that, “these paintings, some of which can still be seen especially near the old village sites, consist of geometrical arrangements of red lines…”. Cahuilla elder Katherine Saubel provided information about her grandmother having painted rock art as a young woman in connection with female initiation. J. P. Harrington's Serrano ethnographic consultant, Santos Manuel, also made reference to his female relatives (girls and women) painting rock art at sites in the San Bernardino Mountains (Harrington 1986:III:101:260). Benedict (1924:390) also stated that when both boys and girls were initiated among the Serrano, they used a red paint to create drawings on rocks. Pictographic Rock Art in the Antelope Valley Knight, Milburn, and Tejada (2009) list nine known pictograph sites within the Antelope Valley. One additional site at CA-LAN-192 (Lovejoy Springs) has been obliterated by weathering since the 1920s, and another reported for Piute Butte may also have been altered or destroyed. Five of these sites contain Southern California Rectilinear Abstract motifs. These include sites at Big Rock Creek (CALAN-447), Folgate Butte (CA-LAN-2368) (southeast of Lake Los Angeles and east of Lovejoy Buttes), Edwards AFB (CA-LAN-2200), Ritter Ranch (CA-LAN-947), (west of Palmdale), and Fairmont Butte (CA-LAN-298) (fourteen miles west of Lancaster). Two adjacent sites in the Tehachapi Mountains foothills west of Rosamond (CA-KER-273 and CA-KER-1193) contain pictographs that are of the Southern Sierra Curvilinear Style. A site at Shea’s Castle, several miles to the southeast of Fairmont Butte, contains pictographs of the Southern Sierra Curvilinear Style or a possibly related Tataviam style. One additional pictograph site in the Kern County portion of the Valley was too faded or damaged to classify. Southern California Rectilinear Style Pictographic Rock Art in the Antelope Valley The pictographic rock art sites within the Antelope Valley that appear to contain Southern California Rectilinear Style elements are briefly described below. Big Rock Creek – CA-LAN-477/723 This pictograph site consists of an exposed vertical panel containing pictographic elements painted in red paint. The panel is located at the base of a rocky ridge adjoining a small habitation site at the mouth of a relatively narrow canyon. California Rectilinear Abstract Style elements appear on the panel, including diamond chains. The site is known to have been associated with the territory of a Archaeological Research Design for the Antelope Valley Study Area 286 07A3822 Task Order 17 contact-era village called Amutskupeat, located further downstream on Big Rock Creek. This village appears to have been affiliated with the clan territory of Amutskupiabit, further east in Cajon Pass. Folgate Butte – CA-LAN-2368 This site is located approximately three miles [4.8 km] east-southeast of the large village site at Lovejoy Springs. Several different locations at the site contain pictographs. The most important array of pictographs is located in a shallow east-facing cave at the top of the Butte. This locus features classic red-pigment motifs associated with the Southern California Rectilinear Abstract Style. Traces of black and white pigment can also be seen. A shallow cave above ground level on the west side of the butte also contains vertical red line pictographs. On the east side of the butte at ground level, adjacent to a small habitation site, another shallow cave contained pictographs that were obscured during the last half-century by smoke from a bonfire built at the mouth of the cave. Ritter Ranch – CA-LAN-947 A panel of faded red pigment pictographs on a rock outcrop were found at this Transverse Range foothill site, at a spring in the Anaverde Valley, just to the west of Palmdale. Habitation sites are located in this general area. Knight, Milburn, and Tejada (2009:13) identify the pictographs as painted in the Southern California Rectilinear Abstract Style. Fairmont Butte - CA-LAN-298 Faint traces of white and red pigment pictographs, including a red pigment rayed disk, have been observed on an exposed rock face overlooking the habitation site at Fairmont Butte. This particular pictograph has been assigned to the Southern California Rectilinear Abstract Style by Knight (1993:57). Edwards Air Force Base - Ca-KER-2200 Red pigment pictograph elements have been found on the ceiling of a rock shelter on Edwards Air Force Base. They are rendered in red paint. A vertical diamond chain and irregular rectangularrectilinear elements, several large red dots, and an oblong circle were observed. This shelter was apparently not associated with a village site. These elements have been tentatively identified as related to the Southern California Rectilinear Abstract Style. The Southern Sierra Curvilinear Style Pictographs As previously noted, the Southern Sierra Curvilinear Style shares similarities with a pictographic style found in inland Chumash areas. Chumash-style rock art sites such as Painted Cave, Swordfish Cave, Burro Flats, the Sisquoc Creek sites, and interior Chumash sites in the San Emigdio region feature densely packed polychrome fields containing anthropomorphs, supernatural animals, and elaborate wheel-like ‘sunbursts’. The combination of colors in complex curvilinear forms is distinctive. The Southern Sierra Curvilinear Style is found in Kitanemuk, Kawaiisu, and Tubatulabal areas and appears to have been influenced by the Chumash style (Knight 1993, 2016; Knight, Milburn, and Tejada 2009; Archaeological Research Design for the Antelope Valley Study Area 287 07A3822 Task Order 17 Knight, Sprague, and Garfinkel 2011). The Tataviam appear to have had a pictograph style related to, but not identical to, the Southern Sierra Curvilinear Style. In the Southern Sierra Curvilinear Style, the similarities to the Chumash style are evident. The design elements are more elaborate than in the Southern California Rectilinear Abstract Style. Individual figures are often curvilinear and sometimes polychrome. Both anthropomorphic and animal figures appear, as well as abstract designs have curving shapes involving fine details. Sometimes multiple colors are used on a single figure. One can find, for example, stylized figures where red, white, and black outlining are all used in the same figure. Animal-like figures or sunbursts are more elaborate in their design elements than in the Southern California style. There is also a relative absence of the diamond chain and diamond net designs of the Southern California style. The Takic Kitanemuk of the Tehachapi Mountains region were clearly influenced by the culture of neighboring interior Chumash groups, including in their ritual and mortuary practices. The Tataviam, whose territory extended southward from the far western Antelope Valley, also borrowed cultural features from their Ventureño Chumash neighbors to the west. This cultural borrowing occurred within a zone of culture contact that formed part of what Hudson and Blackburn (1986a) called the Chumash Cultural Interaction Sphere (Knight 2016). Direct ethnographic testimony about the creation and religious associations of pictographs within the Chumash Cultural Interaction Sphere is not very abundant. Chumash Cruzeño/Ventureño consultant Fernando Librado did provide limited information on techniques of painting as well as on the meaning of several motifs. He mentioned painted representations of the "eight winds" and also the painting of sun disks (Steinberg 1994:74-75). Librado also mentioned some kinds of painting as being done by members of the 'antap? cult sodality. The ritual function and motif interpretation of painted panels in Chumash territory has continued to be a subject of some speculation. It is known that Chumash shaman Rafael Solares and another Chumash, Joaquín Ayala, were involved in traveling to the mountains behind Santa Barbara to make rock paintings at the time of the winter solstice (Hudson and Underhay 1978:58). Pictograph sites found in interior Santa Barbara County in the San Rafael Wilderness region may be associated with astronomical observatories connected with the Winter Solstice. This was the time of a major Chumash religious festival aimed at restoring the power of the sun. Among the Chumash, the Gabrielino/Tongva, and the Kitanemuk, cleared plaza spaces equipped with feathered prayer poles were used as shrines to leave offerings and direct prayers for community well-being. Such shrine spaces were found both in and adjacent to villages and at more remote landscape features such as mountaintops and springs. It is not clear to what extent rock art sites may also have served as shrines within this tradition of religious practice. For the Chumash and Kitanemuk, ethnographic information does not provide information on the creation of rock art as a regular part of collective community rituals such as initiation ceremonies. In the Tehachapi-Southern Sierra region there is rock art in the Southern Sierra Curvilinear Style at locations that were considered to be portals to an underworld where supernaturals would be Archaeological Research Design for the Antelope Valley Study Area 288 07A3822 Task Order 17 encountered. A cave containing rock art (CA-KER-508) located near Nettle Springs in the Cache Creek drainage (east of Tehachapi Valley) was considered to be such a supernatural portal and was associated with ‘Creation’ (Knight, Sprague, and Garfinkel 2011:112-113). Another cave rock art site in the vicinity (CA-KER-93) was also a place of ‘Creation’ associated with ‘the first people’. Another rock art site portal was located in Back Canyon (CA-KER-2412) further north in the Southern Sierras near Piute Mountain (Garfinkel et al. 2009). The CA-KER-508 and CA-KER-2412 ‘portals’ were believed to be linked by a supernatural subterranean passageway. It is significant that both Kawaiisu and Kitanemuk elders provided sacred stories and other information describing in some detail the religious significance of these rock art sites. Two sites, one in the southwest Antelope Valley and the other in the Tehachapi Mountains foothills west of Rosamond and Willow Springs, have Southern Sierra Curvilinear Style elements. These are described below. Temet Osraniek (Shea's Castle) - CA-LAN-721 Near a spring and habitation site located near the historic site of Shea's Castle, about twelve miles west of Lancaster on the southwest margin of the Antelope Valley, are several rock art panels. Geologist William Blake visited the place and described the rock art in 1853. Knight (1993) has suggested that these motifs could be associated with the Southern Sierra Curvilinear Style. At least one element clearly belongs to this style. It is possible that this motif may have been connected to use of the site or visits to it by Kitanemuk or Tataviam from the northwest and southwest margins of the Antelope Valley, respectively. Burham Canyon (CA-KER-273 and CA-KER-1193) Neighboring pictograph sites are located in a canyon on the southeastern slopes of the Tehachapi Mountains bordering the northwestern Antelope Valley. Elements painted in black, white, and red are found in a sheltered area underneath an overhanging boulder. This site also includes three rock outcroppings better covered with large and small circular pits, some of which appear to be large enough to have been used as bedrock mortars, while others are of cupule size. Sutton (1982b:29) and Knight and Sprague (2008:113) assigned the rock art of these sites to the Southern Sierra Curvilinear Style. The idea has been entertained by researchers writing on the rock art of the region that the Southern Sierra Curvilinear Style was associated with ethnic groups of the Southern Sierra and Tehachapi regions, and possibly the Tataviam, and that its presence could be used as a prehistoric ethnic marker. Further research regarding its spatial and temporal distribution, its internal stylistic variability, and its connection to ritual and religious practices, is needed to test the validity of this assumption. The relation of this type of rock art to ritual and religious practice has to do with whether the focus of this rock art was the activities of shamans as individual supernatural operatives or whether the creation of this rock art reflected the performance of community ritual. The remembered mythological associations of some rock art sites in the Tehachapi region hint at the possible importance of shared community religion and ritual in the creation of this type of rock art. However, Archaeological Research Design for the Antelope Valley Study Area 289 07A3822 Task Order 17 such community ritual contexts would appear to be distinct from those found among Takic groups, where elaborate initiation ceremonies are directly linked to the creation of pictographic rock art. Pitted-Rock Petroglyphs and Cupules Pitted Rock Petroglyphs are widely found in California and the Great Basin, having been reported for over 500 sites in Southern California alone (Meighan 2000:17). These consist of rock outcroppings, blocks, or boulders on which circular depressions or dimples have been excavated. Occasionally larger diameter cupules may be found located in the midst of a field of smaller ones. While an isolated cupule on a boulder may sometimes be encountered, it is typical to find a rock surface containing many of them relatively evenly spaced. On approximately horizontal surfaces of softer rock the diameters of the cupules may be larger. Vertical surfaces of harder rock may be covered with smaller-diameter cupules. Horizontal, vertical, and angled rock surfaces may be covered with cupules. In Southern California, cupules are often found on isolated rock outcroppings located near springs or habitation sites. Occasionally, cupules may also be located inside rock shelters or on cave walls (Smith and Turner 1975:10-11). The cupules tend to be uniformly circular and are shallow in depth in relation to their diameter. Cupules are often only a few centimeters in diameter, but scattered individual cupules may be as large as 15 cm across. The individual cupules may be scattered across a rock surface at random or may be aligned in linear or circular patterns. Individual cupules may also be connected by linear incisions, either deep or shallow, cut into the intervening rock surface. Deep grooves between cupules may require substantial removal of rock, while shallow ones may be created by superficial pecking of the rock surface. The linking of individual cupules by grooves may create complex curvilinear patterns within the cupule field. In addition, grooves may be incised on rock surfaces adjacent to cupule fields, but that do not connect individual cupules. Meighan (2000) has suggested that the creation of cupules involved acts of personal prayer: It is reasonably well documented that cupule rocks are places of supplication for some desired event, the pits being made as accompaniment to individual prayers. Repeated use may lead to covering the entire surface of the boulder with pits, sometimes arranged in circles or lines. This form of decorating the rocks must be considered a practice of the common people, rather than sacred or esoteric, since cupule rocks are usually in the middle of village middens and not in isolated or special locations (Meighan 2000:17). Serrano elder Manuel Santos related how Serrano hunters who wished to achieve success in the hunting of rabbits undertook rock carving as part of ritual to obtain supernatural aid (Bean et al. 1981:48-49, 78-79, 114-116). The creation of cupules on rock outcrops as an element of rain-making magic has also been suggested for other areas of California (Parkman 1993). It has also been Archaeological Research Design for the Antelope Valley Study Area 290 07A3822 Task Order 17 suggested that cupule boulders were markers delineating the routes of foot trails (Smith and Lerch 1984). Bean, Vane, and Young (1991:53) mention Cahuilla sacred story material making reference to rocks with small circular marks on them indicating trails. Cupules have also been described as associated with promotion of female fertility (Barrett 1952), as providing star maps for astronomical observations (Hedges 1980), and demarcation of territorial boundaries (DuBois 1908). Sutton et al. (2009) suggested that cupules were at least sometimes used as containers. Arguments have also been made that cupules were ‘functional’ rather than religious or ideological in origin on account of their having been used for sharpening personal implements. Cupules in the Antelope Valley Knight, Milburn, and Tejada (2009) list fourteen sites in the Antelope Valley where cupules on rock surfaces occur. Some seven of these sites consist only of cupule boulders and outcrops. These sites tend to be found in foothill areas along the southern and southwest margin of the Antelope Valley. Cupules have been recorded at the Big Rock Creek pictograph site (CA-LAN-447), and at sites CALAN-767, -768, and -3343 in the Ana Verde Hills just west of Palmdale on the north edge of Sierra Pelona ridge. In the Sierra Pelona ridge area to the southwest, Knight, Milburn, and Tejada (2009:14) report some 30 cupule sites. Cupules are also found at Fairmont Butte (CA-LAN-298 and 1789/H). Regarding the setting where cupule boulders were found in the Anaverde Hills area, Knight, Milburn, and Tejada (2009:14) comment: The Anaverde Hills cupule sites are all located on small knolls at the mouths of fairly small canyons that contain much greater native plant density and diversity than found at nearby areas. The plant species, which include elderberry, desert plum, and mariposa lily, are more robust than plants growing even short distances away. Many bird species are also present, which suggests that other kinds of animals would likely be attracted to the thickets of plants. These areas associated with the San Andreas Fault rift zone were favorable for human habitation at spring and creek sites along the fault, and sometimes featured relatively soft metamorphic rock associated with the fault system, such as steatite. Cupules have not received the archaeological research attention that they deserve because of the persistence of problems of interpretation of their cultural context and function. Petroglyphs in the Antelope Valley As indicated by Knight, Milburn, and Tejada (2009), petroglyphs are rare, as they identify only five clear cases of pecked, incised, or otherwise worked petroglyphs in the Antelope Valley area. Two of these (CA-LAN-3343 and a Forest Service site without a trinomial) have serpentine motifs, while a third is an apparent isolated example of a Great Basin Curvilinear style petroglyphs boulder, lacking any additional archaeological context. The contrast between this lack of petroglyphs in the Antelope Valley area and their greater frequency in the southern Sierra region as well as in other regions of the Mojave Desert is noteworthy. Archaeological Research Design for the Antelope Valley Study Area 291 07A3822 Task Order 17 Summary Both pictographic and petroglyphic rock art occur in the Antelope Valley Study Area. Two styles of pictographic rock art are found in the Antelope Valley area, the Southern California Rectilinear Style and the Southern Sierra Curvilinear Style. Possible cultural and ritual contexts for the creation of these types of rock art are discussed, based in part on ethnographic sources. The differences in styles may be related to different ethnic or cultural affiliations of native populations in different areas of the valley, although this remains only a hypothesis. The occurrence and characteristics of rock outcrop cupules, especially along the southern margin of the Antelope Valley, is also discussed. The scarcity of non-cupule petroglyphic rock art is noted, a situation which contrasts with that found in other regions of the Mojave Desert. Research Questions and Data Needs Research Questions 1) To what extent does the repertoire of pictographic motifs from Antelope Valley sites, conventionally classified as conforming to the Southern California Rectilinear Style, differ from motifs similarly classified that have been recorded from sites further south in Southern California? 2) Are the pictographic motifs in the Southern California Rectilinear Style found in the Antelope Valley similar to motifs found in areas occupied by various Serrano clan groups in and around the San Bernardino Mountains? 3) Is it possible to identify distinctive pictographic motifs found only in the Antelope Valley area, along with a choronological sequence and possible variation through time? 4) Does the hypothesis that Southern California Takic groups created pictographic rock art at locations proximate to village settlements, where initiation ceremonies were held, appear to be supported by the distribution and association of Antelope Valley rock art sites? 5) Will further documentation of pictographic rock art sites in and around the Antelope Valley support or contradict the concept that the geographical distribution of the Southern California Rectilinear Style and the Southern Sierra Curvilinear Style reflect cultural or ethnic differences between local groups in and around the Antelope Valley? 6) Based on their context and associations, are there pictographic rock art sites in the Antelope Valley that appear to have been used by ritual specialists such as shamans, rather than having been created as a result of community rituals? 7) Is there evidence that any Antelope Valley pictographic rock art sites were used as solstice or other astronomical observatories? Archaeological Research Design for the Antelope Valley Study Area 292 07A3822 Task Order 17 8) Is there archaeological evidence that Antelope Valley pictographic or cupule rock art sites were also being used as shrines where offerings such as beads were being placed? 9) Do the distribution, environmental setting, archaeological setting, and material characteristics of cupule rock art sites offer further insights into the cultural or religious motives for their creation? 10) Can the paucity of non-cupule petroglyph sites in the Antelope Valley be placed in a wider context of regional cultural prehistory in the Mojave Desert? How can regional variations in the occurrence of petroglyphic rock art in the Mojave Desert and adjacent regions (the Southern Sierra) be accounted for? Data Needs Data for these research questions consists of rock art classified by type and style. In addition, the distribution, environmental setting, and archaeological setting (type of site and location of the rock art within the site) must be recorded. More difficult will be to place sites with rock art into a chronological sequence. Reliable methods for dating rock art have yet to be fully developed.

Allen, Ph.D. April 2018 Lithic artifacts from four archaeological sites that were tested and evaluated as part of the SR 138 Northwest Corridor Improvement Project were re-analyzed following the research framework described in the Lithics Technology theme and the Lithic Material Sources theme of the research design. The sites were originally described and evaluated in the Archaeological Evaluation Report for the Project (Mason and Blumel 2015). Lithics Analysis of SR-049 (P19-004620, CA-LAN-4620) SR-049 (P19-004621, CA-LAN-4620) has been identified as a dense prehistoric lithic scatter located approximately 500 meters north of the Fairmont Butte rhyolite source and a major quarry and occupation site (CA-LAN-1789/H). The site was likely disturbed by historic agricultural activity which potentially mixed the top 20-30 cm of soil, which may have resulted in damage to some of the artifacts. It is also close to Highway 138 and may have been subjected to considerable artifact collection. Artifacts were surface collected and 12 shovel test pits (STPs) were placed within the site during Extended Phase I investigations in 2014. Eight of the STPs yielded artifacts and/or charcoal, with low density of artifacts to a maximum depth of approximately 50 centimeters (cm) below the surface. No intact features were noted on the surface or in the STPs. During Phase II testing, two 1x1 meter test units were excavated in 10 cm levels to 1 meter in depth with all removed deposits screened through 1/8-inch mesh. Test Unit 1 was sterile was terminated because of a sterile hard pan at 40 cm. Test Unit 2 was excavated to 60 cm after excavating into the hard pan for 5-20 cm. Three flakes were found in this unit in the 50-60 cm level. Recovered Lithic Assemblage The total lithic assemblage from the investigations of SR-049 is presented in Table 1. There is a total of 388 artifacts, with 262 resulting from the surface collection, 43 from the STPs, and 43 from the test units. A total of 99.5% of the artifacts were rhyolite, with 2 sandstone primary flakes (catalog# 35 and 51) recovered from the surface. A total of 10.8% (42/388) of the assemblage is shatter, 85.1% (300/388) are flakes, 2.1% (8/388) are cores, and 2.1% (8/388) are lithic tools. Most of the cores and tools were recovered from the surface with a total of one each from the subsurface. 2 Table 1. Lithics from SR-049.

Biface thinning flakes are the most common, comprising 76.7% (230/300) of all flakes and 59.3% of the entire lithic assemblage. Secondary flakes were the next most common with 22.0% (16/66) of all flakes and representing 17% of the entire lithic assemblage. Primary flakes (11.0% of flakes, 33/300) and tertiary flakes (0.3%, 1/300) were less frequent with the latter nearly absent from the assemblage. This strongly suggests that the primary lithic reduction activity at the site was the reduction of rhyolite cobbles into bifaces and other blanks. There was very little initial decortication going on at the site; this likely occurred at the source itself. There was also very little tool manufacture or maintenance at the site, as indicated by the low frequency of tertiary flakes. Table 1 also presents the frequency for each type by context (surface, STPs, test units). Shatter is most common in the STPs. Primary flakes comprise a significantly higher percentage of the surface artifacts than the subsurface contexts. Secondary flakes and biface thinning flakes are fairly consistent among the contexts. As noted above, tertiary flakes are nearly absent from the assemblage, even in the deposits screened with 1/8-inch mesh. The interpretation that the site was predominantly a locus for producing bifaces for exchange or use elsewhere is supported by calculation of a biface production index based on the ratio of biface thinning flakes to secondary flakes (230/66 = 3.48 biface thinning/secondary flakes). Lithic Tools Eight lithic tools were recovered from SR-049 (Table 2). Seven of the recovered tools in the assemblage are rhyolite bifaces, seven from the surface and one from the 20-40 cm level of STP 3. One of the surface bifaces is a relatively finished tool (stage III), but the other seven are early stages of manufacture (stage I). A biface exchange index for the entire assemblage (total 3 number of biface thinning flakes/total number of recovered bifaces) is 37.5:1. While the sample size is small, and bifaces could have been removed from surface contexts by collectors, this is nonetheless suggestive of modest levels of biface production for use elsewhere or for exchange. The other recovered lithic tool is a rhyolite uniface (catalog # 42). It is a blade modified on both lateral edges, a rather rare artifact type for the western Mojave Desert. Table 2.

Cores Eight rhyolite cores were recovered from SR-049 (Table 3). Seven were from the surface, and included two unidirectional and five multidirectional cores. A single multidirectional core was recovered from subsurface context, from the 30-40 cm level of Test Unit 2. Cores at the site, though few, do suggest that flakes suitable for use as tools were being produced at the site, along with bifaces. Table 3. Cores Recovered from SR-049 (All artifacts are rhyolite).

Early stage biface production is suggested by the high percentage of biface thinning flakes and the presence of several possibly rejected or discarded stage I biface tools which may have broken during manufacture. In addition, the presence of a significant percentage of secondary flakes and cores suggests that production of flakes suitable for expedient tools or more finished flake tools was another activity practiced at SR-049. Other than a single stage III biface recovered from the surface, there is essentially no evidence of other lithic reduction activities at the site. Since there are no diagnostic artifacts in the assemblage and no chronometric dates, it is currently impossible to assign a temporal period to the site. The site is one of numerous sites near Fairmont Butte where rhyolite was being reduced into at least two products: early stages of bifaces and generalized flakes suitable for modification into other tools, apparently over a long period of time dating back to at least the Pinto Period. Lithics Analysis of SR-051 (P19-004621, CA-LAN-4621) SR-051 (P19-004621, CA-LAN-4621) has been identified as a large temporary campsite with a low density of artifacts. It is located near the Fairmont Butte rhyolite source. The site was likely disturbed by historic agricultural activity which likely mixed the top 20-30 cm of soil, and which likely resulted in damage to some of the artifacts. It is also close to Highway 138 and may have been subjected to considerable artifact collection. Artifacts were surface collected and 33 STPs were placed within the site during Extended Phase I investigations in 2014. Fifteen of the STPs yielded artifacts and/or charcoal, with a low density of artifacts to a maximum depth of approximately 70 cm below the surface. No intact features were noted on the surface or in the STPs. During Phase II testing, three 1x1 meter test units were excavated in 10 cm levels to 1 meter in depth with all removed deposits screened through 1/8-inch mesh. Test Unit 1 was sterile at 70 cm, Test Unit 2 was sterile after 50 cm and Test Unit 3 had a single artifact in the 70-80 cm level and only charcoal in the last two levels. Two radiocarbon dates of charcoal samples tentatively place the site in the Late Prehistoric Period and possibly the Mission Period, though context of these samples is not solid. Recovered Lithic Assemblage The total lithic assemblage recovered from the investigations of SR-051 is presented in Table 4. There is a total of 94 artifacts, with 62 resulting from the surface collection, 19 from the STPs, and 13 from the test units. All artifacts were rhyolite. A total of 21.3% (20/94) of the assemblage are shatter, 70.2% (66/94) are flakes, 4.2% (4/94) are cores, and 4.2% (4/94) are lithic tools. 5 Table 4. Lithics from SR-051.

Biface thinning flakes are the most common comprising 60.6% (40/66) of all flakes and 42% of the entire lithic assemblage. They were the most common type of flake in all three recovery contexts (surface collection, STPs, and test units). Secondary flakes were the next most common with 24.2% (16/66) of all flakes and representing 17% of the entire lithic assemblage. Primary flakes (9.1% of flakes, 6/66) and tertiary flakes (6.1%, 4/66) were less frequent. This strongly suggests that the primary lithic reduction activity at the site was the reduction of rhyolite cobbles into bifaces and other blanks. There was very little initial decortication going on at the site; this likely occurred at the source itself. There was also very little tool manufacture or maintenance at the site as indicated by the low frequency of tertiary flakes. The interpretation that the site was predominantly a locus for producing bifaces for exchange or use elsewhere is supported by calculation of a biface production index based on the ratio of biface thinning flakes to secondary flakes (40/16 = 2.50 biface thinning/secondary flakes). Lithic Tools Four lithic tools were recovered from SR-051 (Table 5). Three of these were utilized flakes and a single uniface collected from the surface, and one was a biface recovered from STP 29 at a depth of 50-53 cm. None of the surface artifacts were extensively modified, all three likely were for expedient use only. The biface was stage I, representing a very early stage of reduction. It was likely found to be an unpromising specimen and discarded. A biface exchange index for the entire assemblage (total number of biface thinning flakes/total number of recovered bifaces) is 40:1. While the sample size is small, and bifaces could have been removed from surface contexts by collectors, this is nonetheless suggestive of modest levels of biface production for use elsewhere or for exchange. 6 Table 5.

Three were from the surface: a possible bipolar reduction core that was exhausted, and two multidirectional cores. One of these two (#97) was likely used expediently as a hammer stone and/or as a heavy chopping tool. A single core was recovered subsurface, at a depth of 60-70 cm in Test Unit 3. It was an exhausted multi-directional core. Cores at the site, though few in number, do suggest that flakes suitable for use as tools were being produced at the site along with bifaces. Table 6.

The primary activity at the site was likely the reduction of local rhyolite cobbles from the nearby Fairmont Butte that had already been significantly assayed with most cortex removed (since the assemblage has few primary flakes, and most flakes have little observed cortex). Early stage biface production is suggested by the high percentage of biface thinning flakes and the presence of one possibly rejected stage I biface tool. In addition, the presence of a significant percentage of secondary flakes and exhausted cores suggests that production of flakes suitable for expedient tools or more finished flake tools was another activity practiced at SR-051. There is very limited evidence of other activities at the site, consisting solely of a few tools for expedient use, one core, and a small number of tertiary flakes. Though there are no diagnostic artifacts in the 7 assemblage, the two radiocarbon dates offer modest support that the site dates to the Late Prehistoric and possibly the Mission Periods. This is an important finding that supports earlier work by Sutton (1982, 1988) and Scharlotta (2010a, 2010b, 2014) that argues that the Fairmont Butte rhyolite source was not restricted to early temporal periods such as the Pinto Period. It also could reflect use of this source by ethnographically known populations in the region during the Late Prehistoric Period and possibly the Mission Period. Lithics Analysis of SRAS-003 (P19-004640, CA-LAN-4640) SRAS-003 (P19-004640, CA-LAN-4640) has been identified as a large temporary camp with a low density of artifacts located on top of a steep hill near Quail Lake. Artifacts were surface collected and 28 STPs were placed within the site during Extended Phase I investigations in 2015. Nineteen of the STPs yielded artifacts and/or charcoal, with a low density of artifacts to a maximum depth of approximately 80 cm below the surface. During Phase II testing, two 1x1 meter test units were excavated in 10 cm levels to 1 meter in depth with all removed deposits screened through 1/8-inch mesh. Artifacts were recovered to a depth of 90-100 cm in both units. Recovered Lithic Assemblage The total lithic assemblage from the investigations of SRAS-003 is presented in Table 7. There is a total of 165 artifacts, with 23 resulting from the surface collection, 81 from the STPs, and 61 from the test units. A total of 35.2% (58/165) of the assemblage are shatter, 62.4% (103/165) are flakes, 1.2% (2/165) are cores, and 1.2% (2/165) are lithic tools. Table 7. Lithics from SRAS-003.

Chalcedony is the most common material (57/165, 34.5%). Chert is the second most common material (23/165m 13.9%). Basalt, fused shale, jasper, obsidian, quartzite, and rhyolite are similar in frequency, ranging from 11-17% of the assemblage. Andesite is rare, with only one artifact. 8 Table 8.

Biface thinning flakes are the most common comprising 54.3% (56/103) of all flakes and 33.9% of the entire lithic assemblage. They were the most common type of flake in all three recovery contexts (surface collection, STPs, and test units). Secondary flakes were the next most common with 20.3% (21/103) of all flakes and representing 12.1% of the entire lithic assemblage. Primary flakes (8.7% of flakes, 9/103) and tertiary flakes (16.5%, 17/103) were less frequent. The material types of flake types show significant differences. Table 9 shows the frequency of flake types by material type. Shatter is represented mostly by chalcedony, chert, and jasper. Primary flakes are represented by basalt, chalcedony, and quartzite only. Secondary flakes are represented by all materials except andesite, fused shale, and jasper, but the majority are chalcedony, chert, and obsidian. Biface thinning flakes are represented by all nine material types, with chalcedony and fused shale the most important materials. Tertiary flakes are CCS and obsidian exclusively. 9 Table 9.

But clearly secondary flakes suitable for use as flake tools are also an important part of lithic production at the site. Pressure flaked tools seem to be confined to CCS and obsidian materials only. Lithic Tools Only two lithic tools were recovered from SRAS-003 (Table 10). Both were recovered at a depth of 0-20 cm in STPs. One (catalog #32) is a stage II obsidian biface medial fragment. The second (catalog # 181) is a jasper uniface with one worked edge. A biface exchange index for the entire assemblage (total number of biface thinning flakes/total number of recovered bifaces) is 56:1. While the sample size is small, and bifaces could have been removed from surface contexts by collectors, this is nonetheless suggestive of modest levels of biface production for use elsewhere or for exchange.

A wide range of materials including CCS, fine grained volcanic material, obsidian, fused shale, and quartzite were used to produce or maintain biface cores or tools at the site. Flakes were also produced at the site, mostly from CCS and obsidian. Pressure flaking was minimal and restricted to CCS and obsidian only. The lack of diagnostic artifacts or chronometric dates prohibits assignment of chronological period. The presence of fused shale has the potential to address research questions involving the use and exchange of this material in the Antelope Valley. Lithics Analysis of SR-101 (P19-004632, CA-LAN-4632) SR-101 (P19-004632, CA-LAN-4632) is in the Antelope Valley. It was subjected to surface collection and six STP units, although lithic artifacts only came from STP 2, 3 and 6. The greatest recorded depth for any artifact is 30-35 cm in STP 6. Recovered Lithic Assemblage The total lithic assemblage from the investigations of SR-101 is presented in Table 12. There is a total of 53 artifacts, with 48 resulting from the surface collection, and 5 from the STPs. A total of 28.3% (15/53) of the assemblage are shatter, 56.6% (30/53) are flakes, 11.3% (6/53) are cores, and 1.9% (1/53) are lithic tools, and there is one unmodified cobble of vitreous basalt that was collected as a possible artifact (this is not likely, however). 11 Table 12.

The most common material is basalt, with 67.9% (36/53) artifacts. Vesicular basalt makes up 28.3% (15/53) of the total assemblage. Chalcedony is relatively uncommon, comprising 3.8% (2/53) of the assemblage. Table 13. Types of Lithics by Material Type for the SR-101 Assemblage.

Secondary flakes are the most common comprising 50% (15/30) of all flakes and 28.3 of the entire lithic assemblage. They were the most common type of flake in both recovery contexts (surface collection and STPs). Primary flakes were the next most common with 43.3% (13/30) of all flakes and representing 24.5% of the entire lithic assemblage. Biface thinning flake are relatively infrequent (6.7%, 2/30) in the assemblage. Tertiary flakes are not present in the assemblage. This strongly suggests that the lithic reduction activity at the site was the initial reduction of basalt and vesicular basalt cobbles into cores or small flakes. A single secondary flake (catalog #47) of chalcedony is in the debitage assemblage, recovered from STP 2 at a depth of 0-20 cm. 12 Lithic Tools One lithic tool (catalog # 44) is in the SR-101 lithic assemblage. It was recovered from the surface and is a basalt primary flake with retouch or modification on two sides. It weighs 49.2 g and is 61.5 x 4.5 x 2.0 cm in size. Cores Six cores are in the lithic assemblage from SR-101 (Table 14), comprising 11.3% of the lithic assemblage. Five multidirectional cores were recovered from the surface, two are basalt, two are vesicular basalt, and one is chalcedony. One basalt multidirectional core was recovered from the subsurface in STP 3 at a depth of 0-20 cm. Cores at the site, though few, do suggest that flakes suitable for use as tools were being produced at the site. Table 14. Cores from the SR-101 Lithic Assemblage.

There is very limited evidence of other activities based on this assemblage at least, consisting solely of a single expedient use modified basalt flake. It is not possible to assign a chronological period for this site based on the lithic assemblage. Although SR-101 has limited information, it is nonetheless important as one possible source for basalt tools and debitage found at other sites in the Antelope Valley. Research Questions Research Themes 5 (Lithic Technology) and 6 (Lithic Material Sources for Flaked Stone Tools and other Artifacts) developed for the Antelope Valley Highway 138 project contain a number of research questions. This section evaluates the significance of the findings from the lithics analyses for SR-049, SR-051, SRAS-003, and SR-101 for each research question. 13 Theme 5 (Lithic Technology) Research Questions There are five related questions dealing with specialized production (1A-1E), and one question on the efficiency of lithic reduction strategies through time. Question 1A. Was there specialized production of large fine-grained volcanic (rhyolite, basalt) bifaces during the Lake Mojave and Pinto Periods in the Antelope Valley? None of the four site assemblages can be dated to the Early or Middle Holocene, and thus none are as of now pertinent to this research question. Question 1B. Was there specialized production of cryptocrystalline silicate (chert, chalcedony, jasper) flake tools for activities such as butchering and plant processing during the Lake Mojave and Pinto Periods in the Antelope Valley? None of the four site assemblages can be dated to the Early or Middle Holocene, and thus none are as of now pertinent to this research question. Question 1C. Was there specialized production of large cryptocrystalline silicate bifaces, especially dart points for hunting large and medium mammals, during the Gypsum Period in the Antelope Valley? While none of the four site assemblages can be dated with confidence to the Gypsum Period (and SR-051 is provisionally assigned to the Late Prehistoric or Mission Periods), there is considerable evidence of biface production at all four sites. SR-049 and SR-051 are both in proximity to the Fairmont Butte rhyolite source and both reflect production of early stage bifaces from this material rather than CCS. A limited number of biface fragments and relatively high frequencies of biface thinning flakes yield biface exchange index values of 37.5:1 and 40:1 for the two sites, which indicates modest levels of production of Stage I bifaces for either exchange or for further modification and/or use elsewhere. While non-bifacial cores and secondary flakes at each site indicate that generalized flake tool production took place, the data do suggest specialized early stage rhyolite biface production. If subsequent investigations can assign these or similar sites near Fairmont Butte to the Gypsum Period or later, it would suggest that in the Antelope Valley CCS did not completely replace fine grained volcanic biface production. Site SRAS-003 in the western Antelope Valley shows evidence of biface production of a wide range of material including CCS. Unlike SR-049 and SR-051, final stage biface production with pressure flaking is present, but only with CCS and obsidian materials. Better chronological information for the site could make it an important site for showing differences in biface production through time and by material type. Site SR-101 does not seem to be a biface production site. 14 Question 1D. Was there a reduction of biface production and an increase in the production of smaller flakes suitable for use as smaller arrow projectile points during the early Rose Spring Period? This question requires more secure chronological control than is available for these four lithic assemblages. Nevertheless, the sites do reveal different levels of biface production and different source materials. Site SR-051, moreover, has some evidence for dating to after the introduction of the bow and arrow. If this temporal assignment is correct, the site shows that rhyolite biface production continued after the technological transition to the bow. Question 1E. Did projectile point size continue to decrease during the late Rose Spring and Late Prehistoric Periods due to conservation of high quality materials such as obsidian and/or changes to hunting smaller mammals? Since no projectile points were recovered at any of the four sites, this question cannot be addressed. Question 2. Do lithic reduction strategies become more efficient over time? The lack of chronological control for the assemblages means that they cannot be directly examined to better answer this question. Theme 6 (Lithic Material Sources for Flaked Stone Tools and other Artifacts) Research Questions This theme has six research questions. Question 1. Can the results of Scharlotta’s (2010a, 2010b, 2014) work in the region to source rhyolite and examine its distribution be confirmed through further application of laser ablationtime of flight-inductively coupled plasma-mass spectrometry analysis? Sites SR-049, SR-051, and SRAS-003 all contain rhyolite artifacts. These source of these materials could be determined by ablation-time of flight-inductively coupled plasma-mass spectrometry analysis and the resulting data would contribute to the dataset compiled by Scharlotta (2010a, 2010b). Question 2. Does the distribution of Antelope Valley rhyolite support Scharlotta’s findings of “stable populations and trade networks for more than 1,500 years, with possible disruptions during the Late Prehistoric Period around 300 B P.” (Scharlotta 2014:240)? This question cannot be answered without chronological control of assemblages. Thus, only data from SR-051 can potentially address this question. It does seem to indicate continued production of early stage rhyolite bifaces in the Late Prehistoric or Mission Periods, suggesting continuity from earlier such sites dated to older time periods. Question 3. Was rhyolite an important resource that was controlled by ethnic groups during the Late Prehistoric and perhaps Mission Periods? Site SR-051 suggests that rhyolite was an important resource for the Antelope Valley into the Late Prehistoric or Mission Periods. Analysis of the distribution of similar sites could be applied to this research question. 15 Question 4. Was fused shale an important alternative to obsidian in the Antelope Valley, and if so what were its sources and when was it used? Only one of the assemblages, SRAS-003, shows evidence for the use of fused shale (for the production of bifaces). The site is the only one of the four that is in the western Antelope Valley nearest to the posited exchange routes for fused shale. Unfortunately, the site cannot be assigned a temporal context, but the fused shale could nevertheless be assessed by PXRF analysis to try to determine its source. Question 5. Did the use of CCS vary significantly through time in the Antelope Valley and to what extent were variations in its use due to availability of other materials such as obsidian? The four assemblages are relevant to this research question as they do indicate quite different frequencies of CCS across the region. Better chronological information would permit this question to be further explored. Question 6. In the Antelope Valley was there a peak of obsidian use during the late Gypsum and early Rose Spring Periods followed by a significant decline? Site SRAS-003 is the only site with obsidian artifacts (2 shatter, 13 flakes which were mostly biface thinning and tertiary, and one biface fragment). These artifacts could be sourced by PXRF and then subjected to hydration rim analysis for an estimate of time period. The assemblage could then be compared to other obsidian samples across the Antelope Valley to help reconstruct changing patterns of source, access, and use of obsidian through time.
