I strongly suspect most of these pics are of a "tidal bore" in China; there is a river in China where due to geography the tide comes in as an actual wave or "bore" during high tides. On a few days of year during Spring tides it's exceptionally strong and people come to watch. I've seen video footage on some documentaries and it looks very very similar.

I do not know the truth of the matter, however this was my exact thought. I'm almost sure I've seen at least one of these before.

Have we seen a photo yet with the guy from the observation deck of the WTC?
