Vast Landslides At Niagara Falls

The American side of Niagara Falls recently experienced a significant change when a large rock mass broke away from the crest, altering its appearance. This event is part of the natural erosion process, which geologists explain causes the American Falls to recede by one inch annually and the Horseshoe Falls on the Canadian side to recede by two to four feet. Over time, this erosion will transform the majestic falls into a series of rapids.
