Niagara Falls
Niagara Falls is a group of three waterfalls on the border between Ontario, Canada, and New York, USA, among the most powerful waterfalls in North America by flow rate.
The falls formed at the end of the last Ice Age as glaciers retreated and water from the Great Lakes carved a path to the Atlantic Ocean through the Niagara River. The falls consist of Horseshoe Falls, American Falls, and the smaller Bridal Veil Falls.
Horseshoe Falls, mostly on the Canadian side, carries the majority of the water flow and is considered the most spectacular of the three. The falls have long been harnessed for hydroelectric power on both sides of the border.
Niagara Falls has been a popular tourist destination since the 19th century and remains one of the most visited natural attractions in North America.
