In my opinion, Half Ascent is the best route on the left side of the cable platform. It's rating is somewhere around 5.5/5.6 and it's currently a bit runout. There are 2 existing bolts (circa 1970) but one of the hangers is missing. If the bolts were replaced, I'd give it a 5.6 PG Rating. Begin directly below the tree and the corner of the big overhang. Look for the clean rock and the rusty, old 1/4" bolt (w/Leeper Hanger). Head straight up toward the sharp(!), yucca thing, then work your way left till you get to the belay tree. Rap here (off 2 ropes) or work your way up and left.
