Scramble uphill between Pedestal and Gill's buttresses. The route starts from the flat detached block that forms a platform below Gill's buttress. From the platform, step across gap on the right side of the thin face. Make several moves up and then a powerful move left on microscopic feet: the iron cross. Your goal is to stick the "Crouton Check valve" (a "crouton" being an old Lake term for a gumby). Now the difficulties have started! Move up the center of the face, avoiding the left edge if possible. May not be quite 40', but it feels like an entire rope length. Beta-intensive.
The story of the first lead
is in the MP Forum.
