I updated a few of my posts today to note that there were alternate descriptions in the latest book about canyoneering in Arizona:
Arizona Technical Canyoneering - by Todd Martin (you may know his website - Todd's Desert Hiking Guide - lots of good information and hike/trip reports)
The other book that is not to be missed in this category is: Canyoneering Arizona - by Tyler Williams (revised edition)
I have not done enough of the hikes in either book to offer a review - but I have had a few good adventures with Canyoneering Arizona and am already excited about some of the destinations in Arizona Technical Canyoneering.
Enjoy! CM
