Below is a Fire Rainbow - The Rarest of all naturally occurring atmospheric phenomena. The picture was captured on the Idaho, Washington Border. The event lasted about 1 hour. Clouds have to be Cirrus, at least 20K feet in the air, with just the right amount of ice crystals. The sun has to hit the clouds at precisely 58 degrees.
Again, I don't know what date this was taken. I just think it's beautiful! :)
