Abstract
Located on the West Tennessee Coastal Plain, Pinson Mounds is one of the largest Middle Woodland ceremonial centers in eastern North America. The site includes at least 12 mounds, a geometric embankment, and associated temporary habitation areas within an area of approximately 160 ha. Of particular significance is the presence of five large platform mounds ranging in height from 3 to 22 m. A series of two dozen radiocarbon determinations indicate that the Pinson Mounds site was constructed and used between approximately A.D. 1-500.
