Start left of the arete and just left of the "9" carved into the rock above. Start on a couple of wide alright pocket/edge and climb up through another crimp into the seam and up into the "9" carving, finishing on the ledge. This is the highest boulder problem and is typically done on a rope. Topping out onto the ledge is easy enough but there is still some choss to be climbed after that to get all the way on top and a fall could easily be lethal.
