Continental Divide crests through this mountain landscape, serving as the high-altitude border between Idaho and Montana and separating the Salmon National Forest from the Beaverhead National Forest. This remote corridor is defined by its dramatic relief and significant mountain passes, most notably Big Hole Pass, which provides a crossing point through the high ridges. The map reveals a network of gulches and drainages, including Thompson Gulch and Bradley Gulch, which feed into various creeks like Nez Perce Cr and Dahlonega Cr.
