Just in case someone really likes that kind of thing:
Pinson Mounds, one of two state archaeological parks, is a special park, set aside to protect the prehistoric remains found there. Managed by the Tennessee Department of Environment and Conservation's Division of State Parks, the Pinson Mounds grouping consists of at least 15 earthen mounds, a geometic enclosure, habitation areas and related earthworks in an area that incorporates almost 1,200 acres. Pinson Mounds is a national historic Landmark and is listed on the National Register of Historic Places.
