#USA, #Canada, Niagara falls
Niagara falls-a cascade of waterfalls on the border of America and Canada, between the state of new York and the province of Ontario. Perhaps, Niagara falls can be called the most effective natural fault of the earth's crust. The Niagara river, which connects lake Erie and Ontario, falls from a 50-meter-high cliff more than 1,000 meters wide. This waterfall is considered to be the most amazing natural wonder of North America.
