This tricky little aid line follows the thin seam between the routes 'Gullwing' and 'Seam'. Free climb up the beginning of Gullwing to a ledge with a small tree. Step to the right side of the ledge and aid up the seam to an ancient bolt (A2+ R). Very delicately continue up the seam in a constant state of wide-eyed fear, precariously placing an intricate series of marginal body-weight pieces with increased bamboozling, mind-boggling difficulty, whilst trying not to load your pants or think about the rather serious ledge fall potential below, until finally it is possible to place a small cam at the top (A3R). Pull up onto the ledge and rappel from the bolted anchors of Zimbra.


A few nuts and cams up to 2", beaks, RURPs, heads, thin blades, hooks, micro nuts, helmet.

There is no fixed gear on this route, and it is possible to hand-place almost all of the pitons.

I think it could go free at a much harder grade than I can climb, perhaps hard 5.12. The rock isn't as solid as you might like it to be and it would definitely be X-rated. Jan 2, 2011

How hard would this be as a free climb? Any guesses? Jan 2, 2011

It is legal as long as nothing is left "fixed" in place. Jan 1, 2011
