Bitterroot National Forest

This spectacular 1.6 million acre forest straddles Idaho and southwest Montana. Half of the forest is dedicated to the largest expanse of continuous pristine wilderness in the lower 48 states - the Selway Bitterroot, Frank Church River of No Return, and the Anaconda Pintler in Montana. Its includes the rugged peaks of the Bitterroot Range and drainages carved by glaciers that form steep canyons. Elevation ranges from 3,200 feet at the north end of the Bitterroot Valley to Trapper Peak at 10,157 feet in the mountains on the south. In the Idaho portion of the Forest, elevations drop to about 2,600 feet along the Selway River and 2,200 feet on the Salmon River.
