Near Prairie du Rocher in Randolph County, Illinois — The American Midwest (Great Lakes)
Modoc Rock Shelter
Excavations uncovered well-preserved hearths, tools, and food remains (animal bones, shells, and plant remains). Archaeologists, botanists, zoologists, and geologists studied these remains to determine how the environment and culture of the Native Americans changed through time.
Projectile Points - These points were fastened on shafts and thrown with a spear thrower.
Perforator - This deer bone perforator was used to punch holes in hide and other materials.
Freshwater Mussel Shell - Native Americans ate mussel meat and sometimes used the shells for spoons and scrapers.
Bannerstone - Made from banded slate, this tool was used as a weight on a spear thrower
Pitted cobble - Native Americans used these to make stone tools
Preforms - These flaked-chert preforms would later be modified into projectile points and other tools.
The shelter has a long history of archaeological research. Archaeologists from the Illinois State Museum and the University of Chicago excavated here in the 1950s. The Museum and the University of Wisconsin-Milwaukee returned to carry out additional work in the 1980s
