Sylvia Lake sits at the heart of this high-elevation mountain terrain within the Flathead National Forest, reflecting a landscape defined by its watersheds and ridge-top divides. The map documents the complex boundary between Lincoln and Flathead counties, a line that follows the crests of the Salish Mountains and the Brush Creek Divide. This geography creates a natural separation between the Kootenai National Forest to the west and the Flathead lands to the east.
