Modoc Rock Shelter: Time-Tucked Under Illinois Cliffs

Tucked away beneath the towering sandstone cliffs, the mighty Mississippi River snakes its way, forming a lucky semiwall that guards the unsuspecting Modoc Rock Shelter. This cosy nook has been a popular habitat spot for eons, quite the treasure trove for understanding the lifestyles of old cultures. Deep under its 28-foot layers of sediment, there's something of a timeline, showcasing leftovers and artifacts that reveal the progression of human life.

The first digs back in the '50s by Melvin Fowler and Irvin Peithman unearthed evidence of four Archaic periods of occupation, capped off with a single later-period stake. These precious findings shed light on how earlier folks lived, offering some fascinating insights into their tools, diets, and routines. This National Historic Landmark from '61 carries with it an even greater significance thanks to its captivating array of archaeological evidence of human habitation.

The site's earliest evidence dates back about 9,000 years to a temporary hunting camp. By 6,000 years ago, families started hanging out here for extended periods. Surprisingly, the site was revisited some 4,000 years ago by small hunting parties. The tools used by these curious folks included concave projectile points, scrapers, choppers, hammer stones, and bone awls. Their diets mainly consisted of deer, raccoon, opossum, birds, and fish.
