This route has a "classic" rating in Roach's guide book. Although this route has a rating of "3rd-4th" class in most guidebooks, it might be tough to kept it at that level without huge rope drag (if you have one). A direct line up the 600 foot ridge line would probably be in the 5.2-5.4 range, due to 2-3 large steps/overhangs encountered on the way.
P1: Start at the low point and head 200feet to a tree belay on the ridge.
P2: This pitch involves 150feet of scrambling to another tree belay.
P3: This pitch angles up to the right and passes the last of the overlaps on the right near a weakness. Work out a belay above the overhang or simul-climb the last 100 feet to the summit.
Descent: Down climb to the north and do a one rope rap to the west.
Light rack to 2 inches.
