The Calumet and Hecla (C&H) Mining Company grew from humble beginnings into the largest and most successful copper mining company in the Lake Superior region. C&H's success and fortune was due mainly to it's location on the copper-rich Calumet Conglomerate Lode. C&H's mine shafts and surface operations were constructed to effectively extract the copper-bearing ore.
Though quiet today, numerous structures remain in this former industrial landscape that allow visitors to connect with the stories of the people who once worked here. The former C&H General Office Building now serves as the Keweenaw National Historical Park Headquarters. The National Park Service also owns the former C&H Public Library and the former C&H Warehouse Number 1.

The largest known quantities in the world of pure, native copper were found on Michigan's Keweenaw Peninsula. In some cases, the deposits were up to 97% pure, requiring little chemical processing to produce ingots of pure copper.
