    After visiting Colorado in the mid-1860s, Hill recognized that miners in the region needed a new extraction method to separate metals from ore. He turned to smelting and secured investors to build a smelter in Black Hawk (pictured here), which opened in 1868 as Colorado's first successful smelter. It revitalized the territory's mining industry.

    In 1879 Hill decided to move his Boston and Colorado Smelting Company from Black Hawk to a more central location in Denver. His company built the Argo Smelter (depicted here) two miles north of Denver. The surrounding area was listed as a Superfund site in 1999.
