Holocene Vegetation Cycles, Land-use and Human Adaptations to Desertification in the Gobi Desert of Mongolia

The 81st Annual Meeting of the Society for American Archaeology, 2017

Vegetation communities have responded to these changes according to temperature shifts and northward to southward movements of the edges of East Asian monsoonal systems. Human groups have lived, foraged, and traveled through the landscape of the Gobi for millennia, adapting their technologies and systems of plant and animal use with the dramatic changes of flora and fauna, and likely contributed to the character of the vegetation communities in the region today. Pastoral nomads living in semi-arid regions are sometimes implicated as contributors to desertification. However, our research at the Ikh Nart Nature Reserve, Dornogovi Province, Mongolia has yielded geoarchaeological and phytolith data which show the opposite effect. Changing landscape and vegetation patterns from the Middle to Late Holocene suggest that early pastoralists might have contributed to a shift away from halophytic desert vegetation, and an increase in semi-arid desert-steppe grasses. We suggest that the halophytic succulents growing around saline ponds during the Mid-Holocene wet phase, were replaced by Stipa and other steppic grasses after pastoralists entered the region, increasing hillslope erosion which covered the saline sediments of the valley floor, and encouraged the growth of grass seeds carried in the dung of herd animals.

$Table 1 Geoarchaeological field description of the EW-14-01 geo-section from each sample. Phytolith counting was conducted at 400 x magnification. Single-cell phytolith morphotypes were counted to 300 or more individuals. Single-cell phy- toliths are morphotypes which originate when silica in solution fills in individual cells of plant epidermal tissue. When this silica hardens, it takes on the shape of that indi- vidual cell. Sometimes silica forms a cast of whole sec- tions of adjacent cells. These become multi-cell phytoliths (Rosen 1999). Because multi-cell forms are composed of varying numbers of cells, they were tallied separately. Multi-cell phytoliths were counted up to 100. The aim was to record absolute counts of phytoliths expressed as “number per gram sediment”. The number of phytoliths on the slide was calculated using the following algorithm: to the laboratory S Standard protocol using gravity sedi- mentation, dry-ashing, and heavy liquid floatation. A ca 800 mg sub-sample of the < 250 micrometer size fraction was weighed out. These sediment aliquots were treated with 15 ml of 10% HCl to remove any pedogenic calcium carbonates. The HCl solution was then removed by wash- ing in reverse osmosis water (R/O water) and centrifuging three times. Clays were dispersed by adding 20 ml of a5% solution of Sodium hexametaphosphate and distilled water in a tall 400 ml beaker. Water then was added to a height of 8 cm. After 70 min the water was poured off, and the cylinder was refilled with R/O water, which was left to set- tle for 60 min and then was poured again. This process was repeated until the suspension was clear, separating out the clay-size fraction. The organic matter in the residue was removed by heating to 500 °C in a muffle furnace for 2 h. The samples were transferred into 15-ml centrifuge tubes. Then 3 ml of Sodium polytungstate solution calibrated to 2.3 specific gravity was added to each tube. The sample was centrifuged at 800 rpm for 10 min. The tubes were removed, and the suspension containing the phytoliths was poured into clean 15-ml tubes. Distilled water was added to the tubes to reduce the specific gravity, and then the tubes were centrifuged at 2,500 rpm for 5 min. After two such treatments, the clean phytoliths were transferred into beakers, dried, and weighed. Entellan (Merck) was used to mount a weighed aliquot of circa 2 mg of residue$

This volume illustrates how significant opportunity and chance are in peoples' projects and careers. Paraphrasing Goebel (Chapter 8), although archaeologists have superpowers, we do not have X-ray vision with respect to being able to predict everything surrounding a project, and most of the authors stress that one should always be prepared to adapt. Nothing within archaeology is particularly simple or easy but it is very much worth doing, which is evident in wonderfully described scenarios that are problematic or unexpected but seem to turn out mostly okay, if not better, in the end. This book is a welcome addition to the academic literature because of its meaningful insights into the actual practice of archaeology. Because of its structure and content, I could envision it being utilized effectively in a variety of archaeological courses, including introductory, methodological, and prehistory-oriented. Beyond formal coursework, the volume provides inspiration through stories of trailblazing, coming back stronger from adversity, and the passion that leads archaeologists to success.

Mojave River and Archaeology: Desert and River in the Mojave

The Antelope Hill Project, Part 1: A Class Ill Archaeological Survey and Treatment Plan of the Wellton-Mohawk Irrigation and Drainage District Quarry at Antelope Hill, Yuma County, Arizona

Antelope Hill (AZ X:8:7 ASM) is a well-known archaeological site in the lower Gila River valley. ... more Antelope Hill (AZ X:8:7 ASM) is a well-known archaeological site in the lower Gila River valley. The hill is located approximately 50 km east of Yuma, Arizona, on the southern terraces of the Gila River. As early as the late 1920s, the various prehistoric and historic cultural elements of the prominent landform had already been recorded by archaeologists. But even prior to this time, explorers had visited or heard tales of the hill beginning with Father Garces in 1775. Both the archaeological evidence and the historical record are consistent. They document use of the hill by various Native Americans, of which the primary groups were the Quechan, Cocopa, Kamia, Pima, and Maricopa. Economic use centered on quarrying and production of milling implements. But the hill also carried a wider cultural significance. The large number of petroglyphs found on the hill have been variously interpreted as territorial markers or as symbols used in ceremonies associated with quarrying activities. Later use of the area by Euro-Americans is also abundant. Military encampments, a Butterfield Stage Station, irrigation works, and transportation corridors were all located on or near Antelope Hill. Clearly, this prominent point was a vital location in the history of the lower Gila River.

Students can access extensive resources that far exceed the collections in their classrooms or school library. Especially with the rapid growth of the Internet during the last decade, the gateway to a rich array of sophisticated resources is literally a click away. Curriculum content can be differentiated by complexity and depth, and those gifted students with the ability to process large amounts of information quickly (Siegle, 2004) can race down the information highway at breakneck speeds. “The Internet is the single most significant technology available to gifted and talented students” (Siegle, 2005, p. 30).

On the Shores of Silver Lake, Mojave Desert, California: Late Holocene Shoreline Features and Functional Hypotheses

California archaeology, Jul 3, 2017

Along the western and northern margins of Silver Lake (one lobe of remnant late Pleistocene Lake ... more Along the western and northern margins of Silver Lake (one lobe of remnant late Pleistocene Lake Mojave) near Baker, California, there are three locations where groups of circular/oval and linear stone features constructed of local cobbles and boulders extend from the latest Holocene shoreline out onto the playa. At two of these locations, other stone features on talus slopes just above the playa seem to be associated with the features on the playa. We hypothesize that the playa features functioned to facilitate resource procurement during times when the playa was flooded from the middle to late Holocene. We further hypothesize that the ring-shaped or arc-shaped features on the talus slopes were temporary dwellings, windbreaks, or storage units used concurrently with the playa features.

Prehistoric Bighorn Sheep Procurement Tactics in the Colorado Desert: A Hypothesis for a Stone-Feature Complex in Yaqui Pass, Anza-Borrego Desert State Park, California

The stone-cairn line features are sometimes associated with stone walls, either natural or built, which may represent hunting blinds. The stone features are within or adjacent to areas known to be regularly used by groups of bighorn sheep (Ovis canadensis). Here, we argue that the lines of rock cairns and associated structures form complexes that were both built and used by indigenous people for procuring bighorn sheep. Several lines of evidence support this hypothesis, including behavioral characteristics of bighorn sheep, locations where stone-feature complexes have been recorded, ethnographic accounts, biological observations, and data from radio-collared bighorn sheep in Anza-Borrego Desert State Park. R o c k c a i r n s a r r a n g e d i n l i n e s a n d regularly spaced have been recorded in several areas of Anza-Borrego Desert State Park (ABDSP) and elsewhere in the region. The function of these linear features has remained an enigma. Here, we focus on one feature complex in Yaqui Pass, 1 and consider ethnographic, archaeological, historical, and wildlife conservation data to support our hypothesis that this, as well as other similar stone-feature complexes, were used in prehistoric times to procure bighorn sheep.
