A spectacular dawn sky silhouettes a Giant Saguaro cactus in Tucson's Sonoran Desert. I literally stumbled out of bed and out the door of our beautiful Bed & Breakfast digs to snap one or two frames of this sublime dawn. I had intended to snap some postcard scenics of silhouetted Saguaro Cactii and the jagged Tucson ridges, but was quite pleased to encounter such an intense sky.
