Photos taken in 2007/8 during my stays in the Sonoran Desert across the mountains west of Tucson, Arizona USA, the Photo Odyssey's 136th and 141st camps.

More specifically, the photos here were taken in the northeastern region of the desert, which extends much further west into California and south into Mexico and, as can be seen in these photos, the Sonoran Desert is not a barren wasteland like some deserts, but is actually teeming with life, both flora and fauna, at least in this region of it.
