Niagara Falls (French: les Chutes du Niagara) are massive waterfalls on the mighty Niagara River, straddling the international border separating the Canadian province of Ontario and the United States State of New York. The falls are 17 miles (27 km) north-northwest of the City of Buffalo, New York, 75 miles (120 km) south-southeast of the City of Toronto, Ontario between the twin cities of Niagara Falls, Ontario, Canada and Niagara Falls, New York, USA.
Niagara Falls is composed of two major sections separated by Goat Island: Horseshoe Falls on the Canadian side of the border and the American Falls on the United States side. The smaller Bridal Veil Falls also is located on the American side, separated from the main falls by Luna Island. The Niagara Falls were formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age ), and water from the newly-formed Great lakes carved a path through the Niagara Escarpment en route to the Atlantic ocean. While not exceptionally high at 167 feet, the Niagara Falls are very wide and scenic. Source: adapted from Wikipedia
