The Miamisburg Mound served as an ancient burial ceremonial site. Archaeologists partially excavated the mound in 1869. A vertical shaft was sunk from the top to the base, with two tunnels extending horizontally from it. While digging, the investigators found one skeleton covered with bark about eight feet down. A second log vault was discovered 36 feet below the top. The vertical shaft passed through layers of ashes and stone implying that the Mound was built in several stages. No other parts of the mound have been excavated since.
