1964 Map of Trapper Peak

About this map

Trapper Peak rises as the dominant landmark of this high-elevation terrain in the mid-1960s, anchoring a landscape defined by glacial cirques and alpine lakes. The area is split by the Wilderness Boundary, which separates the managed lands of the Bitterroot National Forest from the protected Selway Bitterroot Wilderness. Access through this steep terrain is primarily limited to narrow routes like the Tin Cup Pack Trail, which follows the course of Tin Cup Creek. The map documents a complex system of drainage and storage, with numerous high-country water bodies such as Chaffin Lake, Tamarack Lake, and Baker Lake feeding the eastward-flowing creeks. Distinctive features like the ridge known as The Lonesome Bachelor and the prominent Sugarloaf Peak provide essential orientation for navigation through this backcountry.
