The greatest copper mine in the Copper Country (and probably the world) was born from pure happenstance. While surveying the military road running between Fort Wilkins at Copper Harbor and Fort Atkinson in central Wisconsin, a man by the name of Hulbert stumbled across a peculiar find. It was an ancient Indian storage pit, left by native miners from Isle Royale. The pit was filled to the brim with a copper treasure, and prompted Hulbert to secure the land around it. Purely by chance, those ancient miners placed their copper storage pit directly atop the great Calumet Conglomerate lode, which it didn’t take Hulbert long to discover. The Calumet Mine was born.
Just to the south of the Calumet Mine a second mine opened on the same lode – the Hecla Mine. The lode proved just as productive as the Calumet to the north, and soon the two mines (along with two other minor mines) combined to form the Calumet and Hecla Mining Company. Though now one mine, the two parts of C&H regained their original identity. North of Red Jacket Road were shafts of the old Calumet Mine (labeled Calumet #1-5), and south of the road sat the shafts of the old Hecla Mine (labeled Hecla #1-8).”
