New Mexico trails · Tusas Loop
A 12.0-mile out-and-back in New Mexico, with 939 ft of climbing. Reaches Road Tank Number One and other lake destinations. Managed by the U.S. Forest Service.
The climbing leans toward the first third: 53% of the ascent falls between mile 0.0 and mile 4.0. It gives back about 1,189 ft along the way, so it rolls rather than climbing steadily.
