This long awaited edition has gotten a little thicker with the addition of over 700 new routes. The drawn topos appear to be all re-drawn and the extensive use of photo-topos are a great addition. New visitors to the park should have no problem finding the route of their choice. The bouldering section of the book has been expanded quite a bit (45 pages total) and now includes photo-topos and V-scale ratings for problems. This edition is broken down into the same logical area specific chapters.
Disappointingly, many of the route and area descriptions have been toned down. For instance, gone is the classic Shiprock description "Only blockheads with enough experience to know better should try." Am I nit-picking at this point? Yes. There isn't much to criticize about the 2nd edition. Get this book and feel free to leave the 1st edition, Smith Rock Select, and all the supplements at home.
