Where we went in Arizona is right at the northern edge of the Sonoran Desert. This is the desert that covers most of the American southwest and is associated the 'fork-like' classic American saguaro cactuses. Our place is situated at the base of the foothills that mark the northern boundary of the desert. Once you climb up into the foothills all the saguaros cactus disappear and you start to see cottonwoods, grasslands, and, even higher up, pinyon pine.
Where we were staying you looked out of the flats of the Sonoran desert - all catclaw mesquite, palo verde trees and saguaro cactuses. Look the other way and you saw low mountains and foothills. It was a very interesting place to be - right on the edge of 2 ecotones.
