A trip to Yellowstone National Park in Wyoming isn’t complete without viewing the majestic Lower Falls. When visiting the park in 2012, Stuart Burnett and his wife Patti captured this shot of Lower Falls legendary rainbow thanks to detailed research and planning. Of the experience, Stuart says, “You could hear the gasp from the other viewers as the rainbow formed. It was just magnificent!! It lasted for about 10 minutes … 10 minutes that I will never forget!!” Photo courtesy of Stuart Burnett. Posted on Tumblr by the US Department of the Interior, 7/3/16.
