These lacustrine environments provide a predictable water source and are ecological hubs for many species of mammals, waterfowl, and vegetation. The availability and abundance of resources create an environmental pull within the Plains that is ideal for ancient hunter-gatherer site choice in a region where resources are relatively scarce. This thesis provides an ecological and human behavioral approach to analyze the ancient history of mobile peoples by examining 18 archaeological playa site assemblages totaling 5,052 artifacts from the Central Plains. The lithic assemblages are placed within a geographic and environmental context, taking into consideration elements of site choice such as distance to playa, topographical location, and playa size. The data reveal that site selection includes many complex factors not always determined by resource acquisition or the surrounding environment. The results also illustrate regional differences in playa occupation, specifically that occupations in the South Platte River Basin are more diverse and continuous when compared to playas elsewhere in the Great Plains. The findings from this research casts light on overall hunter-gatherer lifeways and reveals the importance of playas to indigenous groups in the Central Plains over a 12,000-year history.born digitalmasters thesesengCopyright and other restrictions may apply.
