Some of the canyon hikes are technical in nature with rappelling through some of the best slot canyons in the world (some of these technical slots are new to this book and aren’t in the author’s other book, Technical Slot Canyon Guide to the Colorado Plateau). The last third of the book concentrates on the history of Indians, early white explores, ghost towns, ranches (including the Robbers Roost Ranch), miners, and a chapter on the Life & Legend of Butch Cassidy. It also has sections on Geology, wild horses & burros, plus the latest on the Henry Mountains wild buffalo herd. 288 pages, 308 mostly color photos, 15 cm x 23 cm (6"x9")
