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.
