This unspoiled land of breathtaking beauty confounded the Lewis and Clark expedition in 1805. Created with the passage of the 1964 Wilderness Act, the 1.3 million acre Selway-Bitterroot Wilderness has been a designated wilderness longer than any other part of Idaho. This is the third largest roadless area in the lower 48, surpassed only by Death Valley and the Frank Church River of No Return wilderness. In fact, only a dirt road called the Magruder Corridor separates the Selway from the Frank.
Included in the Selway-Bitterroot wilderness is the Moose Creek ranger station, which packhorses and airplanes can access, along with rafters on the Selway River. Some of the nearby towns are Grangeville, Idaho, and Darby, Montana.
