There is history beneath St. Louis that most of us drive over every day without a second thought. Not abandoned tunnels or lost breweries, but something far older. Entire landscapes were shaped by people whose presence here predates the city by centuries, and their story is still unfolding.

Kyle Olson, an archaeologist and historian who teaches the archaeology of the St. Louis region at Washington University in St. Louis, will be this month’s presenter. His field school—where he first learned to excavate—was at Cahokia’s Mound 66 (“Rattlesnake Mound”) with Dr. Tim Pauketat, one of the leading Cahokia scholars.
