Recent radiocarbon dates of the effigy mound called Serpent Mound indicate that it was built by the Fort Ancient people of the Mississippian civilization, between AD 1170 and 1270. It had previously been thought to be Hopewell. Serpent Mound is over 1300 feet long and includes a later village and burial mound site.
