The Salmon National Forest and Bitterroot National Forest converge at the high-altitude boundary between Idaho and Montana. The terrain is defined by dramatic elevation changes, where features like Blue Nose and Beartrap Ridge loom over deep drainage systems. The small settlement of Shoup is positioned along the Salmon River near the junction of China Gulch, serving as a remote outpost in this mountain landscape. In the southern portion of the quadrangle, water resources such as Horsefly Spring and the headwaters of Boulder Cr underscore the area's hydrology. The map captures a complex network of forest roads, including Nat For Dev Rd 044 and Salmon River Rd, which trace the difficult topography of Boulder Basin and Horsefly Gulch. This 2013 survey provides a clear view of the jurisdictional overlaps between Ravalli Co and Lemhi Co.
