Glacier Peak Wilderness

Glacier Peak Wilderness is a 566,057-acre , 35-mile-long , 20-mile-wide wilderness area located within portions of Chelan, Snohomish, and Skagit counties in the North Cascades of Washington. The area lies within parts of Wenatchee National Forest and Mount Baker National Forest and is characterized by heavily forested stream courses, steep-sided valleys, and dramatic glacier-crowned peaks. The dominant geologic feature of the area is 10,541-foot Glacier Peak. It is the most remote major volcanic peak in the Cascade Range and has more active glaciers than any other place in the lower forty-eight states. Glacier Peak is a volcanic cone of basalt, pumice, and ash which erupted during periods of heavy glaciation.
Glacier Peak Wilderness was created by the U.S. Forest Service in 1960 through the efforts of the North Cascades Conservation Council, four years before the 1964 wilderness legislation of the Congress.
