Selway-Bitterroot Wilderness
The Bitterroot Mountains form a rugged, glacier-carved border between Idaho and Montana. On both sides of this border is the Selway-Bitterroot Wilderness, the third largest Wilderness in the Lower 48. Only the 600-foot-wide Nez Perce Trail (The Magruder Corridor), an unimproved dirt road, separates the Selway-Bitterroot from the Frank Church-River of No Return Wilderness.
