EIGHTEENMILE WILDERNESS STUDY AREA

 

Values

The Eighteenmile Wilderness Study Area (WSA) in north-central Idaho is remote, rugged and mountainous - moving from foothills to grassy meadows to the steep scenic cliffs along the Continental Divide, which forms a significant portion of the eastern boundary of the WSA. The vegetation varies from sagebrush-grass communities at lower elevations to forests of Douglas fir, lodgepole pine, and whitebark pine, and to alpine tundra at the highest elevations. The WSA is a popular area for non-motorized big game hunting in the fall. Visitors also enjoy excellent opportunities for solitude and for hiking, backpacking, rockhounding and wildlife viewing. The Continental Divide National Scenic Trail follows a portion of the eastern border of the WSA between the Pass Creek and Chamberlain Creek drainages.
