Description : The Mann Site (12 Po 2) is a Crab Orchard culture site located off Indian Mound Road in Mount Vernon, Posey County, Indiana. It was placed on the National Historic Register on October 1, 1974. Exotic ceramics and other artifacts found at the site reflect contact with Ohio Hopewell and Swift Creek culture people of the Georgia Piedmont and Gulf Coastal Plain. The site is a large late Middle Woodland period multicomponent complex of mounds, geometric earthworks and habitation sites near the confluence of the Wabash and Ohio Rivers in extreme southwestern Indiana dating between about 100 and 500 CE. It is located on a high river terrace. The scale and complexity of mounds and other earthworks at the Mann site is rivaled in the Midwest only by the Hopewell sites of southern Ohio and whose population size may have been on a scale unparalleled by any of the Ohio centers and perhaps by any other Hopewell site in the Midwest.
