Mount Rainier Wilderness

Mount Rainier Wilderness is located on the west side of the Cascade Range, approximately 50 miles southeast of the Seattle-Tacoma metropolitan area. At 14,410 feet, Mount Rainier itself is the most prominent peak in the Cascade Range. It dominates the landscape of a large part of western Washington State. The mountain stands nearly three miles higher than the lowlands to the west and one and one-half miles higher than the adjacent mountains. Twenty-six named glaciers spill down the slopes, covering approximately 37 square miles, making it the most heavily glaciated peak in the contiguous United States. Mount Rainier is an active volcano that last erupted approximately 150 years ago.
