The horse is central to many Indigenous cultures across the American Southwest and Great Plains. However, when how horses were first integrated into lifeways remain contentious, with extant models derived largely from colonial records. We conducted an interdisciplinary study of assemblage historic archaeological remains, integrating genomic, isotopic, radiocarbon, paleopathological evidence. Archaeological modern North show strong Iberian genetic affinities, later influx British sources, but...
Abstract At an altitude of 2705 m in the Colorado Rockies (USA), Ziegler Reservoir fossil site gives a rare look at high-elevation ecosystem from late Pleistocene (especially MIS 5) North America. Remains more than four mammoths and about 35 mastodons dominate macrofossil assemblage. Mammoth remains are attributed to Mammuthus columbi , mastodon referred well-known, continent-wide Mammut americanum . Mastodon occur within between several lake-margin slump deposits. Their deposition must...
Understanding the trajectories of culture change Plains Indian groups western Great immediately prior to contact is crucial developing a true understanding impacts European technologies and peoples. This article analyzes late precontact movement using Comanche as case study in order better understand this portion indigenous history so critical proceeding postcontact processes. The ramifications expansionism are subject considerable scholarship, but first historical documentation group 1706,...
Abstract In North America, terrestrial records of biodiversity and climate change that span Marine Oxygen Isotope Stage (MIS) 5 are rare. Where found, they provide insight into how the coupling ocean–atmosphere system is manifested in biotic environmental biosphere responds to change. 2010–2011, construction at Ziegler Reservoir near Snowmass Village, Colorado (USA) revealed a nearly continuous, lacustrine/wetland sedimentary sequence preserved evidence past plant communities between ~140 55...
Abstract The vertebrate record at the Ziegler Reservoir fossil site (ZRFS) near Snowmass Village, Colorado ranges from ~140 to 77 ka, spanning all of Marine Oxygen Isotope Stage (MIS) 5. contains least 52 taxa macro- and microvertebrates, including one fish, three amphibian, four reptile, ten bird, 34 mammal taxa. most common is Ambystoma tigrinum (tiger salamander), which represented by >22,000 elements representing entire life cycle. mastodon, Mammut americanum , mammal, documented...
We argue that variation in Younger Dryas-aged fluting the Great Plains and Rocky Mountains was primarily conditioned by cold-mediated time budgeting concerns. Foragers lived cold environments had more to flute projectile points during prolonged periods of downtime relative those warmer, southerly environments. show meets expectations a model because (a) its frequency is negatively correlated with temperature (b) it most often executed interior spaces, presumably downtime. Aided channel flake...
The postcontact period on the western edge of Central Plains was a dynamic technological and territorial change for Indian groups that began with acquisition European-derived goods equines often long before actual physical contacts Europeans or Euroamericans. These highly mobile adaptable maintained many traditional precontact subsistence practices despite procurement these materials animals. Understanding changes wrought by introduction European technologies contact groups, along...
This article analyzes the unusual trading post concentration—Fort Vasquez, Fort Jackson, Lupton, and St. Vrain—that operated simultaneously along South Platte River during late 1830s. These posts, or forts, dealt almost exclusively in bison robes provided by Sioux, Cheyenne, Arapaho hunters. The reasons behind this locus, which was unique to fur trade era of western Great Plains, are examined context indigenous instrumentality ecological factors. Heretofore unexamined environmental...
Comparison of Late Paleoindian sites the Great Plains and Rocky Mountains reveals 36 site components from 28 containing ground stone tools, including nine Cody Complex examples. Much use appears related to generalized activity, as few items have functionally specific forms. However, an unexpectedly higher number grooved abraders compared other complexes. We note that examples contain wider u-shaped grooves Prehistoric/Protohistoric arrow production. argue represent shaft abraders, used in...
