This is the most obvious and best problem on the west face of the Left Plethora Boulder. It starts with a hard move, followed by an easier crack section, and then a difficult top out. Start this problem sitting in the obvious hueco and make a funky move up to the crack. Stand up to the horzontal crack and find a few edges over the bulge, rock your feet up start grabbing desperately for whatever you can hold on to.
This is route #4 in the second Left Plethora/Left Gonad picture.
A pad or two and a spotter are nice.
