This is a short but stout climb in a fairly remote area of the Sierra Nevada Mountain Range. While we think the sign at the beginning of the climb is an exaggeration (26% grade), this climb will test you in a few spots, including 10%+ grades at the very beginning for 1/2 mile. Miles .5-3.0 average 10.0%, and there is a 3/4 mile stretch from 6.0-6.75 that averages 12.3%. As can be seen from theYouTube Playlist the views along this climb of high sierra forest and granite rock faces are spectacular. The climb can be done as an out-and-back 2 climber by going down the east side of Highway 108, then back up Sonora Pass East.
This climb is fairly distant from other Top 100's with the nearest climbs being #77 Monitor East 47 miles north and the Owens Valley climbs starting with Pine Creek 120 miles south. The Pacific Coast Trail crosses the summit of Sonora Pass East/West.
