Mt Douglas anchors this high-altitude landscape along the border of Park and Sweet Grass Counties, where the Custer National Forest and Gallatin National Forest meet. The terrain is defined by dramatic elevation changes across the East Boulder Plateau and Breakneck Plateau, featuring a dense network of glacial lakes and mountain peaks. The drainage system is particularly intricate, with Rainbow Creek and Upsidedown Creek carving through the granite before feeding into the Boulder River.
