Abstract
48SW2302 is a prehistoric site located in the Bridger Basin of southwestern Wyoming and is associated with a stabilized sand dune. Archaeological investigations were conducted here in 1980 and 1981 as part of the Mid-America Pipeline Co. (MAPCO) Project to mitigate the impact of pipeline construction and gather information about regional aboriginal settlement patterns. Five natural strata were defined, six cultural features were exposed, and hundreds of chipped stone artifacts and animal bones were collected. Charcoal from two features returned radiocarbon assays whose calibrated calendric ranges overlap between ca. A.D. 615 and 755. All evidence indicates that 48SW2302 was occupied by Late Prehistoric peoples who hunted artiodactyls and rabbits, cooked and ate those animals, and manufactured or modified their lithic tool kit. They responded to local climatic variations by dietary changes. The site is representative of a ubiquitous and relatively stable pattern of prehistoric settlement and subsistence in southwestern Wyoming.
