Calumet

The Calumet and Hecla Mining Company built a substantial complex of buildings around the Red Jacket and their other mines early in the twentieth century. Those buildings, now the heart of the Keweenaw National Historical Park, are a truly impressive monument to the miners who toiled far beneath the surface in what was then the planet's deepest mine.

This building, according to the site's map (available at the park but not on their website), was the Drill Shop.
