Niagara Falls is the collective name for three waterfalls which are located on the border between Canada and the United States. The three falls – Horseshoe, American and Bridal Veil Falls, form the southern end of the Niagara Gorge.
The Horseshoe Falls, also known as the Canadian Falls, is one of three falls that make up Niagara Falls. Approximately 90% of the Niagara River flows over Horseshoe Falls.
It is the most powerful waterfall in North America, as measured by vertical height and also by flow rate. The falls are located 17 miles north-northwest of Buffalo, New York.
The Niagara River flows from Lake Erie to Lake Ontario. The Niagara Falls creates the highest flow rate of any waterfall in the world, with a vertical drop of more than 165 feet.
The Niagara Falls International Rainbow Bridge was built in 1941 near the site of the earlier Honeymoon Bridge, which had collapsed on January 27, 1938, due to an ice jam in the river. It is estimated that six billion pounds of water cross under the Rainbow Bridge every minute.
