From Yahoo! Australia:
With more than 2.2 million litres of water plunging over its edge each second, the sheer power of the Niagara Falls is humbling to behold. However, while I expected to be awed by such a tremendous force of nature, I was ill prepared for the full extent of its beauty. Clear and glacial green, the Niagara River falls in curtains to Whirlpool Bay. Its lace border of white, foamy spray, in juxtaposition to the massive falling river, is nature conforming to the aesthetic rules of feng shui. The delicacy of the foam is accentuated by the contrast to the thundering torrents beneath it.
