1894 Map of Hermosa

About this map

Gold mining operations and early Black Hills settlements define this 1894 survey of the borderlands between Pennington and Custer counties. The landscape is marked by the industrial footprint of the Etta Mine and the clustering of mountain communities like Keystone, Sheridan, and Rockerville. These high-country settlements, often tied to the mineral wealth of the gulches, contrast with the valley outposts of Hermosa and Fairburn situated along the Missouri River and Northwestern Railroad.
