Lolo National Forest and Clearwater National Forest converge at the high-altitude divide of the Bitterroot Range, marking a significant stretch of the Montana-Idaho state line. This 2014 survey documents a landscape defined by dramatic elevation changes, where peaks like Lightning Peak and Crater Mtn overlook a complex network of alpine water bodies. The presence of French Lake, Hidden Lake, and the clustered Trio Lakes suggests a terrain shaped by glacial activity, providing a detailed record of the wilderness hydrology at the turn of the 21st century.
