William O. Douglas Wilderness: Okanogan-Wenatchee

The William O. Douglas Wilderness was designated in 1984 and now encompasses 169,081 acres. Named for the late U.S. Supreme Court Justice William O. Douglas who was noted for his concern for civil rights and environmental protection. Douglas made his home adjacent to the Wilderness near Bumping River, and immortalized the area in his popular book, Of Men and Mountains.

The western peaks are characterized by high elevation lakes in forests and the eastern slopes drop to mid-elevation pine forest, alpine peaks, and exposed basalt tables and points. The southern portion of the Wilderness spreads out into a large plateau, where the forest thins and lakes collect. The western side receives as much as 120 inches of precipitation per year, while the eastern side may get as little as 20 inches. Snow usually starts to fall by November and often lingers in patches in higher elevations until mid-summer. 

Many trails cross the William O. Douglas Wilderness which ranges in elevation from 3,000 to 7,000 feet. The Pacific Crest National Scenic Trail (PCT) runs along the 27-mile crest of this Wilderness.

Help protect your wilderness by following wilderness regulations and using Leave No Trace principles.
