Establishing at the start is tough. Pull on with left hand on a good sidepull and right hand on a tiny thumb-catch knob and fire for the slopey lip, hang on tight to match and crank out the rad sloping topout. There are some sharp little crozzlies on the lip that help you stick, but tear the crap out of your fingertips.
Location
On the mostly blank side of the Whale Shark Boulder, left of the V3 arete, starting on a sidepull that seems to be the wall's sole feature. Walk off the other end.
