Oregon trails · Surveyors Ridge
A 17.5-mile out-and-back in Oregon, with 2,327 ft of climbing. Reaches Bald Butte and other spring/summit/viewpoint destinations. Managed by the U.S. Forest Service.
Most of the climbing sits in the first third — 56% of the ascent, between mile 0.0 and mile 5.8. It gives back about 2,536 ft along the way, so it rolls rather than climbing steadily.
