About this map

Bishop Mountain serves as a prominent vantage point within the Targhee National Forest, crowned by a documented Lookout Tower that overlooked this high-country landscape during the mid-1960s. The topography is defined by a series of significant drainages including Porcupine Canyon, Cooney Canyon, and Smead Canyon, which carve through the high ridges of Thurmon Ridge and Big Bend Ridge.

Water management and natural springs are central to the area's geography, evidenced by several small impoundments such as Sagebrush Spring Reservoir, Wet Weather Reservoir, and Hidden Lake Reservoir. A complex network of backcountry routes, including the Bishop Mountain Road and various jeep trails, provided access for forest management and local travel near the Island Park Reservoir spillway. The map captures the specialized mountain terrain before modern recreational development, noting specific landmarks like Moonshine Mtn and the passage through Green Canyon Pass.
