Niagara Falls, located at the junction of Ontario, Canada, and New York State, is the world's first large-span waterfall. And with Iguazu Falls (located on the border between Argentina and Brazil), Victoria Falls (located on the border between Zambia and Zimbabwe) known as the world's three large-span waterfalls. The Niagara River, which connects Lake Erie and Lake Ontario, is only 56 kilometers long, but drops from 174 meters above sea level to 75 meters above sea level. There is a limestone cliff across the river. The Niagara River, with an average flow rate of 2,407 cubic meters per second, suddenly falls and forms Niagara Falls. The water of Lake Erie flows into the United States and Canada through Coat Island on the cliff of the riverbed, separated into two parts. Within the United States, including American Falls and Veil of the Bride Falls, the waterfall is 55 meters high and its bank length is 328 meters. Note: The bride's veil is separated by the Moon Island beside the broad American Falls. Although it's only a thin strand, it's its own. In Canada, waterfalls are called Canadian waterfalls or Horseshoe Falls. They are shaped like horseshoe and are 56 meters high. The waterfall bank is about 675 meters long. However, the height and width of the waterfall vary with the amount of water. Waterfalls in the United States and Canada come from the same source of water, but only 6% of the water flows from American waterfalls and 94% from horseshoe waterfalls. Horseshoe-shaped waterfalls have a large amount of water. The water rushes into the river in a blue color, while the waterfalls in the United States are in a blue color. Waterfall viewing process in the United States: each person receives a raincoat, puts it on, boards a special waterfall viewing cruise ship: Maid of the Mist. A cruise ship passes through the American Falls and the Bride Falls, enters the Horseshoe Bay, and then returns on its way. When the cruise ship entered the horseshoe-shaped bay, the whole cruise ship was covered with water mist from the waterfall, and it was white. Note: At the edge of the horseshoe-shaped waterfall, there is a viewing platform (located on Goat Island). If you go there and watch the horseshoe waterfall, it will surely work well. Next, the second photo was taken on board the Misty Girl cruise ship (ordinary tourists, who would concentrate on boarding the boat while ignoring the shooting) with a panoramic view of Niagara Falls. Nearby is the American (and bride's veil) waterfall, and in the distance is the horseshoe-shaped waterfall.
