SEIP EARTHWORKS HOPEWELL CULTURE NATIONAL HISTORICAL PARK
Seip Mound is the central mound in a group of geometric earthworks. Farming and erosion have degraded the surrounding earthworks leaving the central mound an outstanding feature. It is 240 feet long, 130 feet wide, and 30 feet high.
Excavations have revealed that prehistoric Indian buildings existed near the earthworks. Today, visitors can see the location of some of these buildings as they are outlined by short posts in the ground. The Hopewell Indians (100 BC-AD 500) built Seip Mound for burials. This culture had a highly developed craft industry, as is evidenced by artifacts found with bodies in the burial site.
