It is hard to believe that the first photo has been made forty minutes before the second one. A storm front moved out of the area at the Black Canyon of the Gunnison the second night we stayed there. What first looked like an early sunset was just a brief episode in the constant change of light. Looking down the canyon from one of the view points along the south rim and watching the development of the weather was as exciting as watching a movie. "Killer light" at its best, with the bonus of a rainbow... :-)
