Beaverhead National Forest land defines the western landscape of this high-elevation mountain quadrangle, where resource extraction and water management are the primary human signatures. The map highlights the industrial history of the region with labeled mines and the specific Monument Mine located along Sullivan Gulch. A network of pack and jeep trails provides access to the remote terrain, connecting water sources like Houlihan Springs to the wider drainage system. The complex hydrology is further marked by the Bloody Dick Ditch, an artificial watercourse running parallel to Bloody Dick Creek, which illustrates the era's reliance on irrigation and water diversion for downstream valley use. In the south-central portion of the map, the Horse Prairie Guard Station stands as a focal point for forest management and local administration amidst the numerous named gulches and creek drainages.
