Niagara Gorge looks like the track eaten into an apple by a worm. Niagara differs from the waterfalls you find in mountains, where a thin stream of water comes down a mountainside, half-flying. Some of them are much higher than Niagara, and perhaps more beautiful, but they lack mass and cutting power. Niagara belongs to the heavyweights, where a whole solid river plunges bodily over a cliff. The real sight from above is the gigantic movement of the falls themselves, digging the gorge. The falls are still moving today. However, our century has tamed it a bit. A lot of water that used to plunge down now goes through the electric power stations, both American and Canadian.
