Great OW climbing on slightly grainy rock. The crux in my opinion is where the cheater flake on the right wall ends and the crack widens momentarily. Once you pull through this (stacking helps) the climbing is sustained but secure.

The finish is an easier wide squeeze.


This left facing corner can be seen from Ivory Tower Center. It is approximately 100 feet right of the Ivory Tower. To get off, you can walk climbers left about 40 feet to a rap station.


If you want to sew it up, bring a 6 C4, 2 #5 C4s, and 2 #4 C4s.

Two bolt anchor.
