........Niagara Waterfall....






Niagara Waterfall

Located between New York and member of Ontario, Niagara Falls is one of the most spectacular natural miracles of the North American continent. It is located on the Niagara river, which flows between the United States and Canada from Lake Erie to Lake Ontario.
Niagara Falls was formed 12,000 years ago, when glaciers retreated to the north, allowing water from Lake Erie to flow over Niagara slopes. Since then, erosion has pushed slightly waterfall about 11 km upstream, forming the Niagara Gorge. 
In 1954, a considerable portion of the U.S. broke away, creating a huge slope in the waterfall.
It is divided into two parts of Goat Island. The greater part of the left (Canadian) is called Horseshue Falls and has a height of 56 feet and the ridge length is approximately 670 meters. The other side, American Falls, from the right half has a height of 58 meters, but  the ridge length is just of 320 meters.
Because of the strong drop of water it forms a mist which, together with sunlight, gives rise to a large number of rainbows.
The huge flow of Niagara Falls is about five and a half million liters per second.
Niagara Falls is a major tourist attraction, bringing millions of visitors each year. Falls can be seen in parks located on both sides of the river, from observation towers, from boats, from Goat Island and Rainbow Bridge, located a short distance downstream. Also, visitors can enter the Cave of Winds, located behind a curtain of water near the waterfall. At night, the waterfall is lit by powerful spotlights, colored, offering tourists a unique spectacle of lights and music.
