Sit on the boulder and match the obvious rail to start. Make a right hand move to a decent crimp at the lip. Cut your feet and suck your legs up, so you don't dab on the boulder. Throw a toe hook out right and maneuver through a full 360 spin on the lip crimps (I really think that is the easiest way). Then move right to a jug and top out.
This is just to the right of the Crack Mantle, the overhanging face that faces the road.
