Kaieteur falls over a 6 - 10 m thick layer of conglomerate which overlies softer layer of sandstone. Rebounding water is eroding the softer sandstone thus creating an overhang. Over the time overhang falls down - thus the front of the waterfall is slowly retreating. Major part of the enormous escarpment has been created by this process - it is possible that waterfall has retreated in such a way for several kilometres.
