Bitterroot National Forest and its high-elevation sister forests meet along the jagged border of Idaho and Montana in this 2013 survey. The terrain is dominated by a succession of granite summits, including Blodgett Mountain and Shattuck Mountain, where glacial activity has carved deep cirques now filled by alpine water bodies. The hydrological pattern is defined by east-flowing drainages like Mill Creek and Blodgett Creek, which descend from the crest toward the Bitterroot Valley. High-altitude crossings like Blodgett Pass provide the primary transit points through this wilderness landscape. This survey documents the intersection of the Clearwater, Nez Perce, and Bitterroot forests, reflecting the complex management of this contiguous mountain wilderness. Small, isolated lakes such as Lockwood Lake and Frog Lake dot the basins below Frog Peak, illustrating the remote character of the Bitterroot Range at the start of the twenty-first century.
