Clamshell Crack is obvious corner crack on the far left side of the wall. Great climbing for the grade, and a nice feeling of exposure at the end.

Climb through a short vertical section of hand and fist crack (crux) then up a lower angle face to the wide crack in the dihedral. Airy moves exit up and left to the anchor.


Start from the left side of the upper tier, near the namesake cave.


Standard rack. A 3.5" piece can be nice for the wide crack in the dihedral.

Though there are bolts to build your anchor on, be careful with your anchor length/placement, as the rope gravitates toward the crack as you lower. Jul 6, 2008

There were no links to rap off so I left some carabiners. Oct 2, 2017
