I just bought the new guidebook at Hyperspud Sports (Yakima) and it is excellent. I have been waiting for a comprehensive Tieton guide with awesome photos/beta/ and more for awhile. Ford and Yoder wrote this guide in the same style (fonts, get located crag topos., and great photos.) as the Frenchman Coulee guidebook.
I want to thank Jim Yoder and Marlene Ford for their hard work. "andyf" (ccc.c) has "created and/or assisted with 147 of the 356 routes there (Tieton)" p. 8. "joepuryear" ( ccc.c) has put up many multi-pitch routes up Goose Egg and he has added a few routes to The Talon. Thank you Andy, Joe, and others for making/developing the Tieton into an incredible climbing heaven.
BUY THE BOOK!
Yes, there really is a reason to live in Yakima: the crags are only 30 minutes away, they are always dry, and there is rarely wind.
