No recent info, but I’d strongly recommend reading the book Gila Descending: A Southwestern Journey by M.H. Salmon if you can find a copy. It’s an account of a 200 mile descent down the Gila and really gives a flavor for the flora and fauna of the area.
Thanks Mick. I found it (and ordered a copy) on Amazon.com Looks intriguing: the cover sports a dog and a cat in the bow of the boat.
