The Bitterroot Range forms a high-altitude border between Idaho and Montana, defining the topographical character of this remote backcountry. Managed as part of the Lolo National Forest and Clearwater National Forest, the area is punctuated by significant summits including Straight Peak and Lightning Peak. The hydrological landscape is dominated by glacial basins and alpine waters, with French Lake, Goose Lake, and Crater Lake providing the source for numerous drainages like French Cr and Goose Cr. Named topographic features such as Buckos Pocket and Louisiana Gulch hint at the local history of prospecting and backcountry travel within Shoshone County and Clearwater County. This survey documents the network of ridges and drainages where the state line follows the divide, including the steep corridors of Snowy Gulch and Fletcher Gulch.
