Intrasite spatial analysis, ethnoarchaeology, and Paleoindian land-use on the great plains: The Allen Site

This paper examines the way in which patterns of human occupation and geomorphic processes interacted to produce a highly structured distribution of artifacts and hearths over a period of over 3,000 years at the Allen site (25FT50), a Paleoindian campsite in southwestern Nebraska. Despite accumulation of roughly a meter of sediment, artifact concentrations remained in almost exactly the same horizontal locations throughout the period of site occupation. Hearth locations varied considerably, but were virtually always located in areas of low artifact density. Considered in light of ethnoarchaeological studies of hunter-gatherer site structure, our data indicate that the excavated portion of the site was at the periphery of a domestic area and was used for secondary discard and other purposes. Trash appears to have been collected and discarded onto previously existing and continuously visible middens throughout the occupation, and new hearths appear to have been located to avoid these middens. We discuss the implications of these patterns for current models of Paleoindian landuse on the Plains and for studies of hunter-gatherer site structure in general.
