America Unearthed (2012)

Scott Wolter investigates a 3000-pound boulder hidden inside the Chicago History Museum's secret storage location. The Waubansee Stone used to be even bigger when it sat along the Chicago River outside Fort Dearborn. Known as the city's oldest piece of art, the stone features the face of a man with closed eyes, parted lips and a chin beard. Some think it was an homage to a local Native American chief, but others believe the stone may have had a more sinister use hundred of years earlier. Scott's search for the truth about the Waubansee stone results in a wild romp through important events in the history of Chicago--from ancient to modern times--in which the Waubansee Stone always seems to have played a role.
