Created about a year ago


A cool free-standing chert cube with faces up to about 20' high. Some nice boulder problems on the left hand side (V0-V5) and possibly some futuristic projects under the big overhang. The tall, clean right hand side has a handful of 5.8+ top rope problems.

There's one manky hangerless bolt above the right hand wall, but it's best to bring a lot of long slings or a 2nd rope to sling a block way back from the edge. There's also a 1" - 2" cam flake immediately behind the bolt, but it's exceptionally loose - don't use it!

Note that the rock is exposed to the wind howling up from Rodeo Beach - it can be pretty unpleasant on cold, windy days.
