Industrial Calumet

Calumet & Hecla Mining Operations from Swedetown Hill circa 1900

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 National Park Service also owns the former C&H Public Library and the former C&H Warehouse Number 1.
