|Pirhana boulder: Traverse starting at the far RH-side of the lip of the boulder. Traverse L-R along the lip through heel-hooks and a great array of holds. Ascend the vertical face of the boulder diagonally to the apex, missing out the obvious large ledge for feet. See link below at 1:18 for a better look. The video also contains footage of the other new problems on this boulder.
