Climb Y Fonts to get onto the wide traverse ledge. About halfway along the ledge is a shallow seam in the upper part of the wall, which should have a peg in it. Gain and climb the seam. The route involves putting both legs deep into the horizontal break, and then making a huge lurch for a distant jug. You need a big cam (F4 or bigger) for the break and a long sling.
