About this map

The settlement of Adair sits at a critical junction of mountain transport and forestry, where the Hiawatha Rail Trail follows the historic rail grade through the Bitterroot Mountains. This 2020 map documents the high-altitude terrain along the Montana-Idaho state line, marking the divide between the Lolo National Forest and St. Joe National Forest. The landscape is defined by a dense network of high peaks including Dominion Peak, Storm Peak, and Grays Peak, which overlook deep drainage basins for Burke Creek and Silver Creek.

Loggers and recreationalists navigate this area via a system of forest development roads, such as National Forest Development Road 391, which connects various lookouts and ridge points like Bernier Point and Malin Point. The presence of Silver Lake and numerous named water bodies like Olentange Creek and West Fork Big Creek illustrates the complex hydrology of the Shoshone County backcountry, where mountain ridges like Malin Ridge separate several major creek systems.
