Copper Culture State Park

The park contains an ancient burial ground used by the Old Copper Complex Culture of early Native Americans, between 5,000 and 6,000 years ago during the Copper Age. It was rediscovered in June 1952 by a 13-year-old boy who unearthed human bones while playing in an old quarry. By July the first archaeological dig had commenced, as part of the program of the Wisconsin Archaeological Survey.^[4]
