Double Rainbow at Devils Tower

Yesterday I finished a road trip that covered 1,800 miles through six states in six days.  Along the way I stayed a night at Devils Tower in northeastern Wyoming, and just before I arrived, I caught this off the highway.

I dropped the sound for the first several seconds because a Marvin Gaye song was playing on the car stereo in the background, and YouTube sends me these threatening e-mails whenever I post something that has external music on it.  You know, because YouTube is a champion of copyright honesty.
