I love this video. My buddy Ravi has an even better one. You can actually see into the water, and get an idea of the massive amount of water falling over the falls. The drop is about 170 feet and on the Canadian Horseshoe side, it's about a 1/2 mile across. Imagine 6 million cubic feet of water every minute. Yes, every minute. One fifth of all fresh water in the world is in 4 Great Lakes. Huron, Superior, Michigan and Erie. The outflow of those lakes all goes over Niagara falls. Amazing.
