1952 Map of Twin Adams Mountain

About this map

Beaverhead National Forest defines this high-elevation landscape in the early 1950s, where mining activity and water management intersect in the Pioneer Mountains. The survey identifies a clear transition in land use, showing an active Mine on the slopes of Twin Adams Mountain alongside numerous inactive sites like the Greenstone Mine and Indian Queen Mine. The network of steep drainages, including Farlin Gulch and Greenstone Gulch, feeds into the Birch Creek system, where the Birch Creek Ranger Station and a nearby Gaging Station monitor the flow. This era of resource extraction is further evidenced by a Lime Quarry, various Mine Shafts, and Mine Tunnels. Agricultural infrastructure is visible in the lower elevations through the Beaverhead Water Co Ditch, which redirects mountain runoff to the surrounding valley floor.
