Cumberland Falls is 68-foot-tall (21 m) located in Kentucky's Daniel Boone National Forest. The falls are one of the few places in the western hemisphere where a moonbow can frequently be seen on nights with a full moon.
Cumberland Falls, sometimes called the Little Niagara, the Niagara of the South, or the Great Falls, is a waterfall on the Cumberland River in southeastern Kentucky. Spanning the river at the border of McCreary and Whitley counties, the waterfall is the central feature of Cumberland Falls State Resort Park and is part of the Office of Kentucky Nature Preserves designated Wild River System.
It is believed the current falls formed as the result of erosion from its original starting place at an escarpment far downstream. The site of the falls was occupied in pre-modern times by a variety of indigenous peoples, and more recently has passed through multiple private owners until eventually being donated, along with surrounding land to Kentucky in 1930.
It is the only site in the Western Hemisphere where a moonbow is regularly visible.
