A good climb for beginning crack climbers because the crack is pretty smooth on the inside and is easy on the hands.


On opposite side of boulder from the Y crack, big crack running up right hand side to the right of two bolt Corona Club climb. North side of boulder.


medium cams, neighborhood of .75 C4 I think. Two rap anchors, two hangers on top of boulder so you can set a top rope if you lead one of the other climbs on the boulder.

This climb was a bit awkward for me both times I've done it. Fun jams to a jug up high, but the feet are a little weird if you are trying to avoid having to jam them deep into the crack.

Couldn't help but laugh when I read the suggested 5.5 rating. Climb is awkward and fairly stout. Don't be fooled. Protects well and good jams can be found. I used a #4 C4 at the last wide section. Bring singles of .5 - #4 C4 and double up on .75/1 sizes.

Hardest 5.5 I think I've ever climbed. Gets a bit off-widthy in sections. The gear is good, and i even managed to get a couple medium sized nuts in. Hard climbing for about the first half, then it turns into a hike.
