2024 Map of Bannock Pass

About this map

Bannock Pass serves as a critical geographic marker along the Idaho-Montana border, where the Continental Divide winds through the high peaks of the Beaverhead Mountains. This recent survey documents a landscape defined by significant national heritage corridors, including the Continental Divide National Scenic Trail and the Nez Perce (Nee-Me-Poo) National Historic Trail. The terrain transitions between the Beaverhead National Forest and Salmon National Forest, revealing a network of remote springs such as Wagonbox Spring and Boche Spring. Transportation history is visible in the naming of Railroad Canyon and various access routes like S Divide Creek Rd, while the hydrology is dominated by the headwaters of North Fork Divide Creek and Canyon Creek.
