Located on the eastern bank of an old river bed, and among the park's thick native oak trees, the effigy mounds once included a community area with 30 circular huts, inhabited by the mound builders.
The 12 (possibly 13) effigy mounds at the site are what survive of this village today.
Entrance into the Effigy Mounds Park is free and open to the public daily.
The Potawatomi people, after being displaced from their native lands further east, most likely in the mid-17th century during the Beaver Wars, settled in the area now known as Indian Mounds Park and near the Whitewater River, now Whitewater Creek.
Recent plans for the west side of Whitewater by the Whitewater Community Development Authority]show a possible expansion of the park that would include an area north of the park and south of West Main Street.
