Niagara Falls

From Klara and Karina

Nigara Falls…… Nature is amazing and on the move.

Niagara Falls were 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, the Niagara Falls are very wide. More than six million cubic feet (168,000 m³) of water falls over the crest line every minute in high flow, and almost 4 million cubic feet (110,000 m³) on average. It is the most powerful waterfall in North America.

The Niagara Falls are renowned both for their beauty and as a valuable source of hydroelectric power. Managing the balance between recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 1800s.

Today the falls has moved more than seven miles upstream due to erosion. Erosion continues today, but the rate has been slowed by the diversion of water upstream for the generation of electricity. We can temporarily maintainthe shape of the falls by slowing erosion, but even modern technology can’t stop geological activity. Niagara Falls is a living, constantly evolving example of the processes that formed it.
