Toolesboro Mounds State Preserve is located in the Southern Iowa Drift Plain landform region and contains a cluster of 7 ancient Indian mounds, a Visitors Center and Museum and a reconstructed prairie. The mounds were built by the prehistoric Hopewell culture, who established villages near rivers and streams from 200 BC to 400 AD. Known for their mound-building, art, and extensive trading, this culture also grew crops, hunted, and fished for their food. The mounds on the preserve were built for ceremonies and burials. Bodies were placed in log tombs and covered with dirt, before being burned and covered again with dirt. They are protected by law. Displays in the Visitors Center include photographs of the Hopewell culture.
The mounds were all acquired in 1976 by the State Historical Society from the Mosier family and the area became an archaeological state preserve in 1981.
