Niagara Falls Facts and Trivia

In 1969, the American side of Niagara Falls was dried for six months to study erosion. The falls consist of three waterfalls: Horseshoe Falls, American Falls, and Bridal Veil Falls. A dam was built to divert water, raising concerns about tourism and potential flooding. The falls are not the tallest but are known for their water volume. The Niagara River formed after the last ice age, contributing to the Great Lakes. The river supports hydroelectric power, thanks to Nikola Tesla's innovations. In 1848, the falls stopped due to ice blockage, causing panic among locals.
