Mt. Thielsen Wilderness: Umpqua
Mt. Thielsen Wilderness encompasses 54,914 acres and runs along the crest of the Cascades 80 miles east of Roseburg and just north of Crater Lake National Park. Elevations range from 5,000' to the 9,182' summit of Mount Thielsen. Born of the same volcanic activity that created Crater Lake, this is the land of fire and ice.
Much of the Mount Thielsen Wilderness is made up of high alpine forests and open meadows. The terrain is moderate but becomes very steep toward the crest of the Cascade Mountains. Timberline stands at about 7,200 feet, just above a forest of mountain hemlock and fir mixed with whitebark pine. Lodgepole pine dominates the vegetation at lower elevations. The many streams in the area carry a substantial amount of snowmelt in spring.
The Pacific Crest National Scenic Trail winds through the Mount Thielsen Wilderness for 26 miles along the summit of the Cascade Range. For a more serene wilderness adventure, hike into Lake Lucille or Maidu Lake on the North Umpqua Trail #1414. The trail passes over deep pumice that was deposited when Mt. Mazama erupted to form Crater Lake. The famed North Umpqua Wild and Scenic River begins at Maidu on its long trek to the Pacific Ocean.
For the more experienced, the climb to the top of 9,182 foot Mt. Thielsen is a nice challenge. The Mount Thielsen Trail enters for approximately five miles from the west to rise above the tree line and, after 200 feet of hand-over-hand scrambling, finally reaches to within 80 feet of the summit and a breathtaking view. The summit itself requires a short technical climb. Sitting at the top of the sharp volcanic pinnacle, it is easy to see why Thielsen has been called "the lightning rod of the Cascades.
