J91

J91 runs 1.7 miles south to north through the Jawbone trail system, starting with a steep, rocky, and rutted climb from the south end. Expect loose rocks, debris, and gradual switchbacks on a sustained grade through dense forest. The trail then follows a narrow ridge before dropping onto a wide, smooth powerline road that passes oil and gas infrastructure. Most of J91 is easy and well-maintained, but a few rocky and steep climbs make it a moderate overall route.
