Ride Description

 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.

     Traffic and Roadway report:  The roadway surface is excellent throughout this ride and  although there is minimal shoulder, traffic is light and this seems to be a safe ride.
