Mount Baker Wilderness



Mount Baker Wilderness is a 119,989 acre wilderness area within the Mount Baker-Snoqualmie National Forest in the western Cascade Range of northern Washington state. Its eastern border is shared with the boundary of the Stephen Mather Wilderness and North Cascades National Park for a distance of 40 miles (65 kilometers). The wilderness extends from State Route 20 north to the Canada–US border. On the west, it is bounded by the foothills of the Puget Sound lowlands.

Almost entirely within Whatcom County, the wilderness lies on the western slopes of the Cascade Mountains. The three forks of the Nooksack River and the Baker River are the major drainages of the wilderness.

Ecology
Vegetative cover is typical of the west slopes of the Cascades including western redcedar, coast Douglas-fir, noble fir, Pacific silver fir, subalpine fir, western hemlock and mountain hemlock, and at higher elevations, alpine meadows. Animals include mountain goats and hoary marmots. On mountains and higher ridges, considerable areas of rock and permanent glaciers (over 10,000 acres (40 km2)) occur.

Geology
The terrain is rugged, with steep slopes and numerous ridges dissected by small intermittent or permanent drainages. Mount Baker (10420 ft48.77734°N, -121.8132°W), an active volcano, is one of the area's most distinctive features. The mountain periodically exhibits thermal activity. The most northern of Washington's volcanoes it stands at 10778 ft. Other major mountains include:
