Niagara Falls, Canada and United States


Niagara Falls isn't just one, but three waterfalls between the twin cities of Niagara Falls, Ontario, Canada, and Niagara Falls, New York, United States. From largest to smallest, the three waterfalls are the Horseshoe Falls, the American Falls and the Bridal Veil Falls.

Niagara Falls was formed when glaciers receded at the end of the Wisconsin glaciation at 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. Over 12,000 years ago, Niagara Falls extended seven miles down river to what is now Lewiston, New York and Queenston, Ontario. Over the years, the brink has eroded, sometimes as much as six feet per year, to its present site.

Interesting Facts:

  • 3,160 tons of water flows over Niagara Falls every second. This accounts for 75,750 gallons of water per second over the American and Bridal Veil Falls and 681,750 gallons per second over the Horseshoe Falls.
  • The water falls at 32 feet per second over the Falls, hitting the base of the Falls with 280 tons of force at the American and Bridal Veil Falls and 2,509 tons of force at the Horseshoe Falls.
  • Niagara Falls is capable of producing over 4 million kilowatts of electricity, which is shared by the United States and Canada.
  • Four of the five Great Lakes (Superior, Michigan, Huron, and Erie) drain into the Niagara River before emptying into Lake Ontario. These five Great Lakes make up almost one-fifth of the world's fresh water supply.
  • The first person to see and describe Niagara Falls in depth was Father Louis Hennepin, a French priest who accompanied LaSalle on his expedition to the Niagara region in 1678.
  • In 1969, an earthen dam was built across the head of the American Rapids, de-watering the American Falls. For six months, geologists and engineers studied the rock face and the effects of erosion. It was determined that it would be too costly to remove rock at the base of the American Falls, and that nature should take its course.
