American Falls, Bridal Veil Falls and Canadian Falls on the USA and Canadian border are collectively known as Niagara Falls. One fifth of all the fresh water in the world lies in the four Upper Great Lakes of Michigan, Huron, Superior and Erie. All the outflow empties into the Niagara river and eventually cascades over the Falls.
At the bottom of the Falls the water travels 24kms over many gorges until it reaches the fifth Great Lake-Ontario. The land between the lakes does not slope at an even grade, but forms a spectacular drop approximately the same height as a 20 story building and this is known as the “Niagara Escarpment”.
American Falls is the second largest of the three falls with a height of 34m and a total length of 290m.
