Light pollution from Douglas, Arizona lights the undersides of orographic clouds over the Chiricahua Mountains, competing with the subtle glow of Zodiacal Light (at left) and the Milky Way (at right) in the clear sky to the west above the clouds. A small footlight illuminates the cactus. Taken from the Painted Pony Resort in New Mexico, north of Rodeo, December 4, 2013.
