The two large earthen mounds, traditionally known as the Indian Mounds, are among the oldest man-made edifices in North America.
These mounds were constructed approximately 6,000 years ago by the Native Peoples and are older than the Egyptian pyramids. A hunting- gathering society constructed these sacred structures and met here periodically for ceremonial activities and secular events.
Please help us preserve these ancient structures by refraining from gathering on or sliding down the mounds.
