Moonbows

Everyone knows that just the right combination of sunlight and water will create a beautiful rainbow. But I'm sure not everyone knows that there is such thing as a moonbow. In Corbin, Kentucky Cumberland Falls sometimes interacts with lunar rays from a full moon in such a way that a colorful bow is formed at the base.

There are only a few places in the world where a moonbow might form; Victoria Falls in Africa, Yosemite Falls in California, Waimea Canyon, Hawaii, and a much lighter one at the New York side of Niagara Falls. The moonbow is still a rare occurrence, where several factors must line up just right. Factors needed for a moonbow? A full moon, cloudless sky, and misty falls. Cold nights in the fall and winter often create good conditions. The internet is full of calendars predicting the best night to observe a moonbow. If you can't make it to these falls on just the right night, you could just scroll down and take a look at a few pictures.
