This is a pretty fun route. It is a little crumbly down low, but it won't slow you down. This route had a strange, alternating height-dependence to it. At first, I felt too tall and cramped under a bulge followed by a big reach and hard to reach clips. This odd pattern continued right through the improbable looking roof near the top. After heaving myself over the lip, I looked down and noticed two jugs that had hidden from me. Anyway, the crux overhang is fun, and there is certainly more than one way to do it even though it looks hard from the ground. It might even be easier if you are short??


This one starts in the middle of the left crag. There is a giant boulder across the trail from the base.... It's the first steep bolt line left of the huge Hummingbird dihedral.


About 6 bolts, and a 2 bolt anchor (Metolius rap hangers).

[Hide Comment] Most fun route on the wall but still on the crumbly side. Not as bad as the others. Sep 19, 2012
