About this map

Mountain Boy Range and the northern reaches of the Fish Creek mountains dominate this high-desert Nevada landscape, where historical mining activity is etched into the steep canyons. Significant silver and base metal operations appear as clusters of activity, including the Mountain Boy Mine, Kentucky Mine, and Silver Conner Mine near the northern boundary. The terrain is marked by a network of unimproved roads and trails that connect isolated water sources like Josephine Spring and McCulloughs Spring to high-elevation points such as Spring Valley Summit and Atrypa Peak.

Evidence of historical prospecting is widespread, particularly around Prospect Mountain and Mahogany Hills. The transition from the flat expanse of Stevens Basin and its Dry Lake to the complex drainage systems of Reese and Berry Canyon and Dugout Canyon illustrates the challenging geography that mineral seekers navigated. This survey captures a specific era of Nevada's resource extraction history, documenting the exact locations of shafts, tunnels, and remote claims.
