Wilderness Categories Information Specific to this Wilderness Year Established 1964 Establishment Notes 90-544, The Wilderness Act of September 3, 1964, Washington State Wilderness Act of 1984 Designation Clean Air Act Class 1 Administrative Mount Baker-Snoqualmie National Forest, Okanogan-Wenatchee National Forests Unique Landscape Features Glacier Peak Wilderness, which shares its northern border with North Cascades National Park, has few equals in terms of sheer ruggedness. Glacier Peak, the highest summit in the area at 10,541 feet, is more remote than any of the state's other famous old volcanoes. Above the tree line (5,000 feet to 6,000 feet), lovely meadows stretch out below the tattered ridges and the dozen or so summits draped with active glaciers, while below the tree line you will wander through dense forest cover. Ultimately, the steep fractured walls and ragged peaks lead to deep U-shaped valleys tangled with huckleberry and other woody plants. Numerous ice-cold creeks splash gloriously through the valleys from their sharp drainages. Other bodies of water include more than 200 lakes, many unnamed and tremendously difficult to access, in various cirques and hidden basins. Wildlife species include several that epitomize Wilderness: grizzly bears, wolverines, gray wolves. Snows accumulate to depths of 45 feet on the west side of the crest. The paths of old avalanches mark some of the forested hillsides. Climbers have put up routes on at least 140 peaks and faces in the area, and the rock climbing rates among the best in America. Blue Mountain, for example, in the northern portion of the area, boasts a 700-foot granite face with routes rated as high as 5.10. Some of the faces in the Wilderness exceed 1,000 feet.
