1962 Map of Proposal Rock

About this map

Beaverhead National Forest encompasses the entirety of this 1962 field-checked terrain, where the landscape is defined by the branching tributaries of the Big Hole River system. The drainage patterns are clearly delineated, with Salefsky Creek and Shaw Creek cutting through the northern reaches, while the North Fork, Middle Fork, and South Fork converge centrally. The topography is anchored by the eponymous Proposal Rock in the southwest, a distinct landmark for those navigating the high country. High-altitude water bodies like Stone Lake and Lily Lake are accessible only by a network of pack trails and jeep trails, illustrating the era's limited motorized access to these remote Montana highlands. This survey provides an exact record of the primitive transportation routes and hydrography as they existed before modern forest management updates.
