The Continental Divide forms a sharp natural boundary through this high-altitude landscape, separating the Beaverhead National Forest in Montana from the Salmon National Forest in Idaho. This 2014 survey documents the complex hydrological patterns of the Bitterroot Range, where numerous glacial cirque lakes such as Slag-a-melt Lakes, Rock Island Lakes, and Albino Lake feed into diverging drainage systems. To the west, the N Fork Kirtley Cr and E Fork Kirtley Cr flow toward the Salmon River, while to the east, waters from Kelly Cr and Little Lake Cr contribute to the Big Hole River basin. Significant summits including Homer Youngs Peak, Sacajawea Peaks, and Ajax Peak provide the primary landmarks for this largely roadless area, with Freeman Creek Rd serving as one of the few managed access points into the backcountry.
