Niagara Falls is a product of erosion. The force of the water tumbling over the Horseshoe Falls continually causes large sections of rock to erode and fall away.
In 1938, the deepest flow of water, which is located at the crest of the Horseshoe Falls, was recorded at 7.6 meters (25 feet). Hydro diversion has reduced the water flow rate.
800 - 600 years ago the Niagara Falls existed as a single water fall. The separation of the water fall into the two water falls: the American & Horseshoe Falls is relatively new in its 12,000 year history.
Recession of the waterfall brought the cascading water to the brink of the bedrock sill known as the Lyell / Johnson Ridge at Hubbard Point. At the Lyell/ Johnson Ridge the cap rock reaches it maximum height above sea level. From this point the height of the Falls diminishes to the site of the current location of the Falls.
