Jenkins Mountain alone is a Class 2 hike that utilizes the old mining road to the Pieplant Mine for some distance before heading off cross country through forest and up steeper tundra and a rocky ridge to the summit. No particular challenges are encountered. Jenkins combines well with UN13,140 and Grizzly Peak following a ridgeline to the south for a much longer day that does involve some obstacles like a difficult ridge section, talus-filled gully and relentless boulder-talus. Lidar measurements added 8 feet of elevation.
