1894 Map of Hermosa

About this map

Mining and early Black Hills settlements dominate this late-nineteenth-century survey of the rugged territory spanning the border between Pennington and Custer counties. The map documents a critical era of extraction, centering on the Etta Mine near Keystone, and smaller outposts like Rockerville, Hayward, and Sheridan. These camps were the lifeblood of the local economy before the advent of modern tourism, established along the steep drainages of Battle Creek and Spring Creek.
