Niagara Falls

A group of three waterfalls on the border between the Canadian province of Ontario and the U.S. state of New York. Together they have the highest flow rate of any waterfall in North America.

Niagara Falls is a group of three waterfalls at the southern end of Niagara Gorge, on the border between the Canadian province of Ontario and the U.S. state of New York. The largest, Horseshoe Falls, straddles the border, while the smaller American Falls and Bridal Veil Falls lie within the United States. Goat Island separates Bridal Veil Falls from Horseshoe Falls, and Luna Island separates it from American Falls.

The falls are formed by the Niagara River, which drains Lake Erie into Lake Ontario, and together they have the highest flow rate of any waterfall in North America. They lie 27 km (17 miles) northwest of Buffalo, New York, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York. The falls were formed when glaciers receded at the end of the last ice age.
