   How did Niagara Falls form?

   • As these huge chunks of ice melted away, the falls formed gradually over time. The water that filled the Niagara River was a result of melting glaciers and it took many years for erosion to shape the cliffs into what we know today as Niagara Falls. For centuries, Niagara Falls has been a natural border between Canada and the United States.

   When did the Niagara River come into existence?

   • The river came into existence late in the Pleistocene Epoch, before about 11,700 years ago, when the margin of a great continental ice sheet melted back and exposed the escarpment of Niagaran dolomite rock of Silurian origin (about 415 to 445 years old), allowing the discharge from the Lake Erie Basin to pour over it.
