Niagara Gorge is a 11 km (6.8 mi) gorge carved by the Niagara River along the US-Canadian border in New York and Ontario.^[1] As Niagara Falls recedes upstream toward Lake Erie, the river has gouged the hard dolomitic limestone of the Niagara escarpment to form the gorge.^[2] The gorge begins at the base of Niagara Falls and ends near Queenston, Ontario where the escarpment ends (and the falls began their long journey southward toward Lake Erie).^[3]

The force of the river current in the gorge is one of the most powerful in the world. It has been whitewater kayaked by world class experts on isolated occasions, but has generally been illegal to run due to lethal hazards if things go wrong.
