Diamond Peak Wilderness: Willamette

  

Image of Diamond Peak Wilderness

Diamond Peak Wilderness straddles the Cascade Mountains. Diamond Peak was formed as the entire land mass of the Cascades was undergoing volcanic activity and uplift. Great glaciers carved the large volcanic peak and when they receded, the bulk of the mountain remained, with snowfields near the summit and dozens of small lakes surrounding the peak.

Lakes are one to 28 acres in size.Diamond Peak Wilderness area covers 52,611 total acres. Approximately 14 miles of the Pacific Crest National Scenic Trail pass through this wilderness. Another 38 miles of trail, including the 10-mile Diamond Peak Trail, stretches the length of the west side of the peak.

Nearly the entire area is covered with mixed stands of mountain hemlock, lodgepole and western white pine, and silver, noble and other true firs.
