NATURE
A Natural Wonder or Not?
Niagara Falls is known for it’s large continuous flow of water and
beauty. The waterfall formed naturally, so why isn’t it considered a
natural wonder?
The Horseshoe Falls was the beginning of the Falls. About 12,500 years
ago near the ending of the Ice Age, recession began at the Niagara
Escarpment. There the gorge was being cut out by undermined dolostone
pieces as they fall from the falling waters of the Horseshoe Falls and
winter ice. The Horseshoe Falls also eroded a thick layer of soft shale
from the underlying bedrock. This all formed the Niagara Falls.
Father Louis H. Hennepin, a Roman Catholic priest, discovered the
waterfall in 1678 with the navigation of the Native Americans. When he
had been on a quest with Explorer Robert LaSalle. Niagara Falls is from
an aboriginal name. Native Americans say “Niagara” means “neck” or
“split in the flatland”.
The Americans and Canadians have been working together to preserve the
natural beauty of the fall. In doing so they’ve dewatered the Falls
before, slowed it’s erosion, and controlled lots of change in the
feature with the help of a hydroelectric dam. Diverting water intake
from the hydroelectric power plants controls the Niagara River. In
order to dewater the Falls a cofferdam was built on the main lands of
Goat Island. Slowing its erosion from 3 to 8 feet per year in modern
times with the help of the hydroelectric power. Also, the fresh lake
water flowing over has been slowed down by 50% to 75%. All of this has
kept surrounding islands from being washed away and kept water flowing
over every fall.
Niagara Falls is the beautiful, naturally formed waterfall that can be
seen from a boundary of Canada and the United States. It carries water
from the Great Lakes that eventually travels into the Atlantic Ocean.
