Keystone and Donlan sit within the high-relief landscape of the Lolo National Forest along the border of Mineral and Sanders Counties. The Clark Fork river cuts a deep path through the northern section of the map, flanked by State Hwy 135 and the level terrain of Donlan Flats. This area is defined by its dramatic drainage networks, where numerous creeks and gulches feed into the river system from surrounding heights.
