Niagara Falls

The US Army Corps of Engineers once stopped water from flowing into Niagara Falls to prevent long-term erosion.

Niagara Falls consists of three different waterfalls

The famous landmark is made up of the American, Canadian, and Bridal Veil falls. Of the three, Bridal Veil is the smallest and forms the other boundary of a small slice of area known as Luna Island, where tourists can view the scene.

Water from four Great Lakes feeds Niagara Falls

Niagara Falls is powered by water from Lakes Superior, Michigan, Huron, and Erie. The Great Lakes basin spans over 260,000 square miles and holds nearly 20% of the world's surface freshwater—about two-thirds of which passes over the falls.

Whirlpool Rapids formed in a matter of days during the last ice age

Niagara Falls' dramatic whirlpool rapids were created in a matter of weeks when the retreating Falls intersected a buried ice age riverbed—generating North America's largest standing waves.

For centuries, Niagara Falls has been a magnet for daredevils seeking to conquer one of nature's most powerful wonders, with its 200-foot drop and water rushing at 32 feet per second with 280 tons of force.

Niagara power helped electrify early New York City

Tesla's AC system at Niagara Falls was so successful that electricity generated there lit up Broadway theaters and powered NYC's subway system in the early 1900s.

A pet turtle survived a fatal barrel plunge over the falls

In 1930, George Stathakis died attempting a barrel stunt over the falls—but his 150-year-old pet turtle "Sonny" survived 24 hours trapped behind the cascade.

Niagara Falls generates its own microclimate

Constant mist from the Falls produces localized weather effects, including rare ice formations that can rise over 100 feet high in winter.

Engineers shut off Niagara's American Falls for six months in 1969

In June 1969, the US Army Corps of Engineers diverted the Niagara River to halt flow over the American Falls. The dry riverbed allowed geologists to study erosion and remove dangerous rock buildup.

Niagara Falls is slowly eroding backward toward Lake Erie

At its current erosion rate of roughly one foot per year, Niagara Falls is expected to retreat all the way to Lake Erie in about 50,000 years.
