MURPHSYBORO, ILLINOIS—A survey ahead of road construction near Southern Illinois Airport revealed a village between 700 and 900 years old. Pots, tools, mussel shells, and deer and fish bones have been recovered, and charcoal in the soil suggests that some of the homes burned down. “It’s sort of unclear if these groups spread out and became parts of what we know as the tribes today. Or if they stayed in this location and became something else, or if they moved away entirely,” Patrick Durst of the Illinois State Archaeological Survey told KFVS 12.
