Niagara is the group name of three. The three waterfalls are the Horseshoe waterfalls (sometimes called Canadian waterfalls), the American waterfalls, and the smaller Bridal Veil waterfalls that are separated by a Luna Island island from the main waterfall.
Although not too high, Niagara is a waterfall that is very wide and most popular in the world. More than 6 million cubic feet (168,000 m3) of water per minute was dropped and this is the most powerful waterfall in North America.
The morning of March 29, 1948, was a special day. The tourists who visited Niagara Falls on the American-Canadian border were amazed when the waterfall stopped flowing.
They watched the waterfall dry out, leaving only rocks with several puddles at the bottom of the stream. What makes Niagara dry? Strong winds and large chunks of ice have apparently blocked the flow of Danai Erie that is the source of Niagara Falls, so the waterfall becomes "lost".
Approximately thirty hours after Niagara stopped flowing, the chunks of ice had broken, and then the watery streams were flowing again, and Niagara Falls again rumbled, to this day.
