This was taken at Cumberland Falls, Kentucky and is a pic of 1 of natures rarest and freakiest events...a Moonbow.
A moonbow id a rainbow from moonlight. It can occur naturally anywhere but is exceedingly rare. Only two places on Earth have Moonbows which occur on a regular basis and this is one of them, the other being Victoria Falls in Africa. Nobody knows for sure why these two places are it, but in part at least it is because they both are a good amount above sea level with fairly pristine waters and at a good distance from major smog or night light concentrations (cities).
To view a Moonbow requires clear skies and a full Moon plus a little patience. It takes a while to get your night vision up to speed so that you can see it at all, once you can it is a magical sight of beauty that is not easily put into words.
It is devilishly difficult to photograph as well. This is my third attempt and each time I seem to get a little closer. If you ever want to try it let me tell you that the long exposures required eliminate modern electronic cameras and digital is a waste of time.
