Wyoming trails · Lowline
A 15.9-mile out-and-back in Wyoming, with 597 ft of climbing. Reaches Poston Lake and other lake destinations. Managed by USFS 040307.
The climbing leans toward the first third: 48% of the ascent falls between mile 0.0 and mile 5.3. It gives back about 1,398 ft along the way, so it rolls rather than climbing steadily.
