Old Copper Sites
The Reigh site in Winnebago County and the Oconto site in Oconto county are two cemeteries of the Old Copper Culture. They date to between 3000 to 1500 BC. They were
excavated in the 1940-1960's by archaeologists. Many human burials with stone, copper and bone artifacts were found here. Many of the artifacts were used for daily
activities, such as points, fishing hooks, and woodworking
and wedges. But many others were special kinds of artifacts that may have been related to ritual or status.
For instance, one whistle was made from the wing bone of a swan. Other copper artifacts include bracelets, rings, pendants, and beads.
