About this map

The Continental Divide serves as the prominent physical and political spine of this high-elevation landscape, where the border between Idaho and Montana separates the Salmon National Forest from the Beaverhead National Forest. This 1965 survey area is defined by the headwaters of numerous drainages, including Pioneer Creek and Nugget Creek, which flow through the mountainous terrain. Exploration and mineral interests are evident through several marked prospects scattered near Morgan Mtn and along the drainages of Thompson Gulch.

Logistics in this remote mountain pass are represented by a network of pack trails and a jeep trail that follow the natural contours of the land, providing access to Big Hole Pass and the secluded Morgan Jones Lake. The map details the complex drainage patterns of the region, from the West Fork Nez Perce Creek in the west to Rabbit Creek and Cow Creek in the east, illustrating a landscape primarily managed for forest resources and wilderness access.
