Nine days after this hike, I hiked over the Sawtooth Ridge and across Cottonwood Creek Basin to Cottonwood Creek Springs and Cottonwood Creek Falls, as described HERE.
The 55,151 acre Mount Thielsen Wilderness runs along the crest of the Cascades from the southern end of the Oregon Cascades Recreation Area to just north of Crater Lake National Park. Elevations range from 5,000 feet to the 9,182 foot summit of Mount Thielsen. Born of the same volcanic activity that created Crater Lake, this is an area with a seriously tortured geology. Last year, we did two hikes in this wilderness, one a loop from the Howlock Mountain trailhead (USFS), up the Howlock Mountain trail (USFS #1448) to the Thielsen Creek trail (USFS #1449) and up that to the Pacific Crest Trail (PCT). We then took the PCT south to the Mount Thielsen trail (USFS #1456), followed the #1456 west to its junction with the Sprague Ridge trail (USFS #1458) and took the #1458 back to the Howlock Mountain trail and the trailhead. It was screaming hot that day, so this became known as the Beau Geste hike (post). About a month later (and on a much cooler day), I did a trail and cross-country hike to Tipsoo Peak (USFS #1472) and the eastern summit of Howlock Mountain, again using a piece of the PCT to make a loop (post). An upshot from this hike was a question about the spring (what we’re calling “Cottonwood Creek Spring” since it appears to be the source of Cottonwood Creek) in the large pumice basin immediately east of Mount Thielsen.Continue reading “Thielsen Creek Divide (Mt.
