where does the water come from at niagra falls
Niagara Falls Niagara Falls was formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly formed Great Lakes carved a path through the Niagara Escarpment en route to the Atlantic Ocean. While not exceptionally high, Niagara Falls is very wide. More than six million cubic feet (168,000 m3) of water falls over the crest line every minute in high flow,[4] and almost four million cubic feet (110,000 m3) on average.[citation needed]
