It might be the largest falls in the world if we will extend the time span. Dry Falls in Washington, U.S.A.
Nearly twenty thousand years ago, cataclysmic floods from gigantic glacial lakes made this falls.
I bet you can not imagine, how huge it is, what is the power of the planet called Earth, until you see by your own eyes. I made a figure for comparison to Niagara Falls.
The view of it with imaginary water flow which was there at one time is breathtaking.
