There have been messages and images shared across the Internet and Social Media about Niagara falls being frozen but that is not the case as of now. It can be clearly seen on the live cam that the falls are not in a state as shown in images circulating the Internet. Every winter, the Niagara Falls do get covered by ice and the same thing has happened this year. Most of the images that we see on the Internet are taken from the year 2007.
Here are a couple of images which clearly show that the falls are covered in ice and snow but still have water flowing.
