West Ridge Route, Class 2 by Livingston Douglas
Middle Fork Little Timber Creek Trail [(A)(8.2)(a) on Page 314]
Hike up the Middle Fork Little Timber Creek Trail for 3.75 miles to a well-marked trail junction at a pass (9,500 feet). From the pass, scramble east across an open grassy field briefly. Then enter the steep, mostly-open forest. Climb northeast up through the forest, staying to the climber’s right/east of the ridge crest.
Higher up, the climb becomes more of a face climb than a ridge climb. At approximately 10,000 feet, climb east up a mix of talus and boulders. Finally, at 10,200 feet, the west ridge becomes well defined. Follow the ridge crest east over a false summit to gain the summit of West Rocky Peak.
