The word "Niagara" is derived from the Iroquois Indian word "Onguiaahra" meaning "the strait". Niagara Falls is composed of two major sections separated by Goat Island: the Horseshoe Falls on the Canadian side and the American Falls on the American side.
The Niagara Falls are huge waterfalls on the Niagara River, across the international border between the Canadian province of Ontario and the U.S. state of New York. The falls are 17 miles (27 km) north-northwest of Buffalo, New York and 75 miles (121 km) south-southeast of Toronto, Ontario, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York.
Niagara Falls were formed when glaciers flow away at the end of the Wisconsin glaciations (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, the Niagara Falls is very wide. More than 6 million cubic feet (168,000 m3) of waterfalls over the crest line every minute in high flow, and almost 4 million cubic feet (110,000 m3) on average. It is the most powerful waterfall in North America.
The Niagara Falls is renowned both for their beauty and as a valuable source of hydroelectric power. Managing the balance between recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 19th century.
