I was in the party of three that same day, and a beautiful day it was, we decided on climbing that open book on the right, it was farily exposed to get into the crack and had a nice 5.8+ boulder move at the top, but it was clean and had good protection.
We also climbed a variation out to the left at the last pitch right before the third class scramble finish. It was a 15-20 foot crack that was fun climbing. All in all a great day of climbing.
