The Niagara Falls were formed, when ice melted, the Great Lakes drained over the Niagara Escarpment by way of the Niagara River. The drainage initially cut a gorge through the escarpment but since the top rock of the gorge was soft it was eroded living the hard rock at the bottom. The unsupported top rocks gave way from time to time creating a sharp edge for the falls.
