Niagara Falls has been transformed into a frozen winter wonderland thanks to recent sub-zero temperatures.

Over the Christmas holiday, western New York was shut down by a storm that was so bad that it was called the “blizzard of the century” by the authorities. Extreme weather that hit the United States for several days shut off power to many people, slowed down travel, and killed a few people. Several pictures and videos have been posted to social media that show how bad the weather is, especially in Buffalo, where bodies have been found in cars and under snow banks.

Now, a video of Niagara Falls covered in ice has shown up on the internet. The recent wave of sub-zero temperatures that has hit the area has turned the falls into a partially frozen winter wonderland. The New York Post said that even though some parts of the falls were frozen, they almost never completely freeze because of how much water goes over and how the water is always moving.

“When it is very cold, the mist and spray start to freeze on top of the rushing water, making it look like the Falls have stopped. But water keeps flowing underneath the sheets of ice, “The website for Niagara Parks says this.

The Niagara Falls New York State Park says that about 3,160 tonnes of water flow over the falls every second. It’s falling at a rate of 32 feet per second.

Before 1964, ice could block the flow of water further upstream, which would freeze the amount of water on the US side of the Falls. Before steel ice-booms were put in place to stop big piles of ice, this happened five times.

During very cold winters, ice and snow often build up over the Niagara River at the base of the falls, making a “ice bridge.” The Post says that on February 4, 1912, three people died when a piece of ice broke off and threw them into the Niagara River. After that, people were not allowed to walk on the ice bridge.
