尼亚加拉瀑布属于重量级——一股巨流全部从悬崖上冲泻下来。从上往下看到的现实景像是瀑布自身的强烈运动在凿峡谷。

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.

Of all the wonders left on earth and formed through movement of nature and living matters, Niagara Falls are one of the most profoundly affecting and magnificent.
