Mount Thielsen Wilderness and the Winema National Forest define this high-altitude landscape along the crest of the Cascades. The 1999 revision captures a territory dedicated almost entirely to conservation and recreation, where the Pacific Crest National Scenic Trail winds through the southwestern corner near Miller Mountain. This area serves as a critical headwaters region, with the Little Deschutes River and Big Marsh Creek draining the complex volcanic terrain.
