The Modoc Rock Shelter is a rock shelter or overhang located beneath the sandstone bluffs that form the eastern border of the Mississippi River floodplain at which Native American peoples lived for thousands of years. This site is significant for its archaeological evidence of thousands of years of human habitation during the Archaic period in the Eastern United States. It is located on the northeastern side of County Road 7 (Bluff Road) southeast of Prairie du Rocher in Randolph County, Illinois, United States. It was declared a National Historic Landmark in 1961.[2]

The site has over 28 feet of sediment that contains artifacts. Evidence from the site, including four separate periods of Archaic occupation and one of a later period, suggests that the cultures of the Eastern Woodlands may have been comparable in age to the big game hunting cultures of the Great Plains. Based on the analysis of artifacts, archaeologists discovered that 9,000 years ago this rock shelter was used as a short-term camp by small hunting groups; by 6,000 years ago this rock shelter was used for long-term based camps by several families which were involved in activities of everyday life; and, by around 4,000 years ago evidence found in the sediment layers suggests the site was again used by small hunting parties as a short-term camp.[3] Their tools included concave projectile points, scrapers, choppers, hammer stones, and bone awls. Evidence has shown that during occupation, the inhabitants had a diet that consisted of deer, raccoon, opossum, birds, and fish.
