The decaying saguaro cactus stands like an ancient Samurai warrior fighting to the death. A decaying saguaro provides food, shelter and moisture to a plethora of insects that slowly devour the plant, leaving only a sun bleached skeleton. The photo was taken in Sabino Canyon, Tucson, AZ. Nikon D810, Tamron 16-300 mm lens, ISO 500, 1/200 sec, f 8.0, focal length 16mm.
