1958 Map of Isolation Peak

About this map

Isolation Peak stands as the central landmark for this high-altitude 1958 survey, where the Continental Divide creates a sharp boundary between the watersheds of Rocky Mountain National Park, Arapaho National Forest, and Roosevelt National Forest. The map documents a strictly non-vehicular landscape, defined by established pack routes such as the East Inlet Trail and the St Vrain Creek Trail. These paths connect a dense network of alpine water bodies, including Thunder Lake, Lake Verna, and Bluebird Lake. The mapping reveals the complex glacial topography of the Wild Basin area, featuring named formations like The Cleaver and the Moomaw Glacier. A lone Patrol Cabin near Thunder Lake represents the only indicated structure, emphasizing the wilderness character of the terrain during the late 1950s.
