About Keweenaw Copper Country — Lake Superior Copper Collecting
The Keweenaw Peninsula is the only place in the world where pure native copper float boulders are found loose on the surface and in stream gravels. The ancient Lake Superior copper culture collected this copper for 5,000 years. Today, rockhounds collect native copper nuggets, prehnite, thomsonite, and epidote from the Lake Superior basalt flows. Several mine dumps allow public collecting.
