1957 Map of Edie Ranch

About this map

The Continental Divide defines the high ridgeline where the Beaverhead Mountains form the border between Idaho and Montana in the late 1950s. This high-altitude landscape is split between the Beaverhead National Forest and Targhee National Forest, featuring towering summits like Heart Mtn and the Red Conglomerate Peaks. The map records a transition from these steep peaks to the drainage basins below, where Medicine Lodge Creek and Lodge Creek provide critical water sources for the remote Edie Ranch. A network of canyons and gulches, including Cole Canyon and McNeary Gulch, reveals the complex hydrology of the region. Local springs such as Robertson Spring and Big Spring serve as important landmarks for navigation through the mountainous terrain.
