Woodland Mounds State Preserve is a 185-acre area featuring a group of five conical burial mounds dating from the years a.d. 400 to 1100. It is located 7.5 miles east of Indianola in Warren County. In 1981, the Warren County Conservation Board purchased the woodland from the Gilbert family, who had owned the property since the late 1800s. In 1983, the property was dedicated as an archaeological preserve and named after the Woodland Indian culture that built the mounds.
