The American Falls is one of three waterfalls that together are known as Niagara Falls on the Niagara River along the Canada–U.S. border. Unlike the much larger Horseshoe Falls, of which two-thirds of the falls is located in Ontario, Canada, and one-third in the US state of New York, the American Falls is entirely within the United States and New York.
The falls receive approximately 10% of the flow from Niagara River, with most of the rest going over Horseshoe Falls, from which it is separated by Goat Island. It has a straight line crest width of about 830 feet (250 m). If measured along the jagged lip of the falls, the crest is about 950 feet (290 m) long (but see coastline paradox). The torrent of water passing over the crest of the falls is about 2 feet (0.61 m) deep.
The height of the American Falls ranges between 70 to 110 feet (21–34 m). This measurement is taken from the top of the Falls to top of the rock pile (talus). The height of the Falls from the top of the Falls to the river is 188 feet (57 m).
The falls are viewable from a steep angle on the American side, where it is possible to approach to within several meters of the edge of the falls. One can view the falls from the bank of the river, as well as on Goat Island and Luna Island, which are accessible by a pedestrian bridge that crosses the rapids of the Niagara River upstream from the falls. The falls are viewable head-on from the Canadian side in Niagara Falls, Ontario.
The ledge of the American Falls is shaped in a modified "W" form, caused by numerous rock falls over the past 150 years which have resulted in the huge mound of rock at its base. The most notable recent rockfall occurred in 1954 with the collapse of Prospect Point to the north.
