context_page_description: Niagara Gorge is an 11 km canyon carved by the Niagara River along the Canada–United States border, between the U.S. state of New York and the Canadian province of Ontario. It begins at the base of Niagara Falls and ends down river at the edge of the geological formation known as the Niagara Escarpment near Queenston, Ontario, where the Falls originated about 12,500 years ago. The position of the Falls have receded upstream toward Lake Erie due to the falling waters slow erosion of the riverbed's hard Lockport dolomite, combined with rapid erosion of the relatively soft layers beneath it. This erosion has created the Gorge.
  The force of the river current in the gorge is one of the most powerful in the world; because of the dangers this presents, kayaking the gorge has generally been prohibited. On multiple occasions, the rapids of the gorge have claimed the lives of people attempting to run them. However, on isolated occasions, world-class experts have been permitted to navigate the stretch.

  Tourists can bounce and splash through the rapids of the Niagara Gorge on commercial tours in rugged jetboats, which are based at Niagara-on-the-Lake, Ontario, at Lewiston, New York, at Youngstown, New York, and in midsummer at Niagara Glen Nature Center on the Niagara Parkway in Ontario.
