Never Ending Flow
Experts say that the flow of water tumbling down Niagara Falls never stops. Even when temperatures drop to freezing point and parts of the Falls freeze, a large quantity of water still cataracts over the edge. Some of the water even evaporates before reaching the basin.
Grounding To A Halt
There was a time in history where it was ground to a halt because of the rocks that accumulated at its base. Well, at least part of it was. Niagara Falls is made up of three waterfalls namely, Horseshoe Falls, Bridal Veil Falls, and American Falls.
