About this map

Mt McGuire dominates this high-altitude landscape in the heart of the Salmon National Forest. The topography is defined by the sharp, glaciated terrain of the Bighorn Crags, a region where massive granite formations like Cathedral Rock and Beehive rise above deep basins. These basins cradle a high concentration of subalpine lakes, including the large Ship Island Lake and smaller bodies such as Shoban Lake, Sheepeater Lake, and Airplane Lake.

The map reveals a wilderness shaped by geological ridges and drainages rather than human settlement. Distinctive spines like Fishfin Ridge, Fishing Ridge, and Gant Ridge separate the various watersheds. Major drainages such as Roaring Cr, Clear Cr, and Goat Cr descend from the peaks, illustrating the complex hydrology of the Salmon River mountains. The lack of roads or structures emphasizes the primitive character of this Idaho backcountry in the early 21st century.
