A friend pointed out a few routes at castle rock that they had mixed up between beta photo and description. There is a trail that is either incorrectly drawn, or just very good at hiding from me at pine creek, mt diablo. I remember finding a few in the north bay as well. Nothing terrible or anything, but can be a bit confusing for someone new to the area. I'll try to be better at documenting them. Or maybe the author has posted them online somewhere.
The book covers most of the good stuff in the area and the pictures are really nice. I'm happy to find some good beta on Pine Canyon but the trail certainly was not in the same spot as on the map. I'd say the trail map for that area in general was pretty poorly done. Over all though the book is one of better ones I've seen for SF Bay.

The trail for Pine Canyon certainly wasn't done in great detail. There are many alternate paths and trails not shown but for the most part, it's all there with the exception of the trail to Deliverance Rock.
To get to Deliverance (which a keen eye can spot on the approach as the only North facing wall below and to the right of the Teeth) get to the notch between the Castle Wall and Castle Rock. You should be at the base of the route know as "the Castle Rock Arete". At this point there is a trail just up hill that heads north toward Deliverance and the Teeth. Follow the trail staying left and very quickly you'll drop down into a wooded gully with no real trail. Walk down hill and follow a short wall (maybe 15ft tall) until you can find a way to scramble and claw your way up to it's arete. Walk left (west) along this sorta ridge top where you'll have to bushwack or crawl through a tunnel in the bushes. At the tunnels end begin looking to your right for the top of deliverance rock and it's steep drop off. It's not super obvious but if you find yourself crawling through bushes and poison oak again, you went too far. You don't need to crawl through any Poison oak if you go the right way. It kinda points the way. Go the wrong way and you'll be confronted with walls of the stuff.
