Copper Culture State Park

Copper Culture State Park is a 42 acre Wisconsin state park in Oconto, northeastern Wisconsin, United States. The park has natural areas, farmlands, archaeological sites, and a Native American museum.

Archaeological site
The park contains an ancient burial ground used by the Old Copper Complex Culture of early Native Americans, between 5,000 and 6,000 B.C.E. 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.

Artifacts
Utilitarian products were much more numerous than ornamental items in the grave goods found, and the ancient artifacts were created from various materials.
 * Copper: awls, crescents, clasps; and a spear-point, fishhook, bracelet, spirally-coiled tubing, rivet, and a spatula.
 * Chipped stone: scraper, projectile points.
 * Bone: awl (fish jawbone), and a "fine specimen of a whistle" (leg bone of a swan).
 * Antler: possible flaking tools.
 * Shell: pond snail (Campeloma decisum) beads.

The ancient burial ground is a National Historic Landmark, on the National Register of Historic Places listings in Wisconsin, and protected within Copper Culture State Park.

Charles Werrebroeck Museum
