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.
