This is a really good crack problem. It starts out as an overhanging finger crack in a hallway, then you can either step off on the rock behind you or for full value, top out the easy 5.8 above. From the top, an easy corridor leads back down to the base. For extra value, sit start the problem, which provides a definite starting point, and bumps the grade to V9. There are many different interpretations of the stand start, with varying grades. This is a very fun, thin finger crack, bring tape.


This is the tall crack splitting the back (south) wall of the formation, the bottom finger crack hidden behind a slab.


A pad, though for the crux start you can just step back if you are going to fall, and after that a pad would be useless.

[Hide Comment] I did this problem in Fall 1986. At the time, I was sure it was a first ascent having cleaned all the critical holds. I called it "Lattice Action". The name had a double meaning, being a term from theoretical physics (I was working on my PhD thesis at CU Boulder) and the action of one's lats as one does two finger pullups on the micro-jams.

In the spring of 1987 I did "Nat's Three Star Roof" which I called "Tunnel Vision". I also believed that was a first ascent. The name refers to the vision of the blue Wyoming sky looking up through the last pod as you approach the lip. Jul 24, 2011
