Mounds State Park, located off I-69 east of Anderson, features 10 unique earthworks built by prehistoric Indians known as the Adena-Hopewell people. The largest earthwork, the Great Mound, is believed to have been constructed around 160 B.C. Archaeological surveys indicate the mounds were used as gathering places for religious ceremonies, from where astronomical alignments could be viewed.
