Rob Vaterlaus and I drove to Castle Rock and did a good day of climbing. We started at Cow Face (?) and did the cave on the left; 5.10A, maybe. Then we moved on to the Underworld, did the main cave with the difficult start (undercling), then did a couple of 10D or 11A routes around to the left.

We planned on camping but the campgrounds all closed at sunset so we just drove back to Berkeley.
