I don't know if this was the largest. Both the mediterranean and the Black sea, each a lot larger than any water body in America.
Anyway, both of those were dry at one point and the water of the oceans broke through. The Black sea went from low lying valley (akin to the dead sea valley, but much bigger) to open sea in less than a week.
I don't know, but that even seems to me must have been pretty spectacular (to watch from a SAFE distance).
That was exactly what I thought about when I read the title. It may have been a very temporary waterfall, but it must have been enormous.
So does the Black Sea waterfall not count because it was so temporary? Was it still somehow smaller than the one from the article? Or has its size not yet been verified?
I think there's a definition of waterfall that includes a longevity requirement; i.e. as there are some "waterfalls" which only exist shortly after rainfall, then dry up again, and thus can't be called waterfalls. I'll try to dig up a reference for that half-recalled fact...
