Calumet & Hecla Industrial Core: "The Footprints of a Giant" Walking Tour #1

They sparked the creation of villages like Calumet and Laurium, housing locations like Hecla, Yellow Jacket, and dozens more. At their heart was the Calumet Conglomerate, a copper-bearing rock formation angled from southwest to northeast along Mine Street.
