Niagara Falls is constantly moving backward due to erosion. The force of water wearing away the rock beneath causes the falls to retreat upstream by several feet per year. This geological process has been documented for over a century, with the falls having moved significantly backward from their original position. The rate of erosion has been reduced by diversion of water for hydroelectric power.
