I recently heard from the Summit Hut Book Buyer that both Todd Martin’s Arizona Technical Canyoneering and Tyler Williams’ Canyoneering Arizona are both out-of-print. Of the two Arizona Technical Canyoneering is more relevant to the Santa Catalina Mountains covering 6 different routes – Canyoneering Arizona only contains limited information on Sabino Canyon in the Revised Edition.
It is worth noting that Canyoneering Arizona was first published in 1998 when canyoneering was exponentially less popular than it is today!
I don’t know if either these books are going to be reprinted – or if new editions might be forthcoming…
