In 1982, the contracting division of the Office of the Wyoming State Archaeologist conducted archaeological investigations at four prehistoric sites, 48CR3812, 48CR3813, 48CR3814 and 48CR3815 in southcentral Wyoming. Archaeological assemblages from these sites range from the Paleoindian Period to the Late Prehistoric Period. Analysis of these assemblages permitted inferences to be made concerning aspects of the settlement and subsistence patterns of prehistoric populations in this area. Investigations at 48CR3812, 48CR3813 and 48CR3814 were confined to surface recording only. The Sage Creek site, 48CR3815, provided most of the information on which the interpretations were based. This site, a stratified multicomponent site, was occupied on a number of occasions between 9,000 and 1,200 years ago.
