1962 Map of Mt Mc Guire

About this map

Mt McGuire towers over a complex landscape of the Salmon River Mountains, where the 1962 field check recorded a dense concentration of high-elevation water bodies and granite formations. This area of the Bighorn Crags is defined by its glacial morphology, featuring numerous cirque lakes such as Ship Island Lake, Airplane Lake, and Barking Fox Lake. The terrain is characterized by sharp ridgelines including Fishfin Ridge and Gant Ridge, which separate the various drainages of Roaring Creek and Clear Creek. The map reveals a network of primitive paths designated simply as Trail, providing the only access through the Crags during the early 1960s. Notable landmarks like the Beehive and Cathedral Rock serve as distinct navigational points within the Salmon River Mountains, illustrating the geologic character of the Idaho and Lemhi County border region.
