Geographic Profile and Landscape Mapping for the Mount Thielsen Wilderness in Oregon
This geographic dataset provides an overview of the Mount Thielsen Wilderness in Oregon, covering a recorded land area of 223 square kilometers. The profile includes elevation measurements spanning from 1500 meters to 2799 meters, alongside a catalog of mapped natural features including glacial landscapes, forested terrain, peaks, lakes, and rivers.
A Cascade Range wilderness centered on Oregon's 'Lightning Rod of the Cascades.'
Mount Thielsen Wilderness
Mount Thielsen Wilderness is a congressionally designated wilderness area in the southern Cascade Range of Oregon, built around the volcanic peak of Mount Thielsen. The wilderness spans across portions of three national forests: Deschutes, Umpqua, and Fremont-Winema, and was established in 1984 as part of the National Wilderness Preservation System. The landscape rises from forested foothills to a sharply pointed mountain summit, with elevations spanning roughly 5,000 feet to over 9,000 feet. Glacial carving has sculpted much of the terrain, producing a mix of rolling ridges, steep dissected mountainsides, alpine lakes, and high-country forests. The wilderness is recognized as one of the more compact and dramatic Cascade Range protected areas in Oregon. To the south, the wilderness borders Crater Lake National Park, linking Mount Thielsen to a broader corridor of protected Cascade landscapes. Within the wilderness, the headwaters of the Wild and Scenic North Umpqua River begin at Maidu Lake, adding significant hydrological value to an already striking mountain environment.
