Located on Bluff Road between Prairie du Rocher and Modoc, Illinois, this great sandstone bluff provided shelter for Native American groups beginning shortly after the Ice Age.
As early as 8000 BCE, these nomadic people, who lived by hunting animals and gathering plants for food and fibers, came here regularly for 6000-8000 years. Later Native American groups, who began to settle in villages, used the rock shelter occasionally when hunting. The pioneers and their descendants continued to make use of the shelter in historic times. Periodic floods from the Mississippi River and nearby Barbeau Creak buried the abandoned camps, creating 25-feet of layered archeological deposits.
