|Moonbow captured by time exposure|
It is also one of only two water falls on earth that exhibit the phenomena known as a "moonbow." The only other naturally occurring moonbow happens at Victoria Falls on the Zambezi River in Africa. Now to capture a photograph of the rare event one must be at the falls on the nights of a full moon. The skies have to be clear and the mist has to be rising over the falls as the water plunges into the deep pool below the falls. And the moon has to be at the just the right angle that the view can see the event. To photograph the pale rainbow (same effect as a rainbow) a tripod and time exposed shot are required. I have noted that the very best months of the year are February, March and April. It is during these months that the moons location in the sky places the angle of refraction close to the falls. This allows for those great photos of the moonbow hovering over the falls and both can be photographed.

There have been reports of placer type gold and silver found in the sands and gravel of the Cumberland River in the area of the Falls. The Swift legend has also been tied to this area of the state. Many of the alleged rock formation landmarks can be identified in this region. The proximity to the Pine Mountain, aka as Jellico Mountain in this area.
Make no mistake the Falls are still actively retreating upstream. In February 1972 a huge section of the cliff fell into the river just below the Falls. The rock fall took out a large section of the Eagle Falls Trail and was certainly a massive rock fall. Thousands of tons of rock and debris fell into the river and ever so slightly widening the river valley. When one stands near the falls joint fractures can easily be seen. Water continually erodes these joints and the underlying rock until eventually another section of the rock creating the falls breaks away. Then the massive water fall retreats a bit further upstream.

|Down the Cumberland River below the Falls are the remains of eroded rocks many of which were once part of the Falls.|
