ABSTRACT Geophysical survey and excavations from 2010–2016 at Lawrenz Gun Club (11CS4), a late pre-Columbian village located in the central Illinois River valley Illinois, identified 10 mounds, plaza, dozens of structures enclosed within stout hectare bastioned palisade. Nineteen radiocarbon ( 14 C) measurements were taken single entities wood charcoal, short-lived plants, animal bones. A site chronology has been constructed using Bayesian approach that considers stratigraphic contexts feature formation processes. The was host to hundreds years continuous human activity during Mississippi Period. Mississippian is estimated have begun cal AD 990–1165 (95% probability) , ended 1295–1450 lasted 150–420 yr primary model with similar results obtained two alternative models. palisade 1150–1230 continuously repaired rebuilt for 15–125 probably 40–85 (68% . Comparison other studies demonstrates one earliest midcontinental United States.
