7.Niagara Falls-Something Completely New 　　

Niagara Falls has become a tired old tourist sight. But if you look it over in an airplane, it becomes something completely new. You realize that it is not tired; only our way of looking at it is tired.

　　Most visitors go as close to the falls as possible, and watch the waters thundering down. It is fascinating, in a stupefying way. You stand there, hyptonized by the sheer force, the untiring action that goes on and on. But afterward you have a feeling - "So what, really? The water comes to the cliff and, naturally, it falls down."

　　But at altitude you see it all at once. You see Lake Ontario on one side and Lake Erie on the other, and linking them the 34-mile Niagara River. Then, coming down lower, you see the falls themselves, along a front almost a mile wide, plunges over a 182-foot cliff and flows off through a deep, narrow gorge. And right away, with a flash of understanding, you see the main fact about the Niagara Falls. The falls are moving, the seven-mile-long gorge is merely the track the falls have made as they move along. This instantly reverses all your ideas. On the ground it seemed that the water fell because there was this low place for it to fall into the gorge. Now you see it is the other way round. The falls are the cause, and the gorge is the result. 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.
