(CBS NEWS) -- While the polar vortex and record-breaking low temperatures arecausing all sorts of environmental phenomena, in this case, the cold may havegone to our heads.

Photographs of NiagaraFalls have circulating the internet with captions claiming that the historicsite is completely frozen over. In reality, Niagara Falls is not frozen over, as you can see from the live webcam.

The falls arepartially covered in ice, which happens every year. In fact, some of thephotographs gaining popularity online, like this one, are not even from2014 (it was taken from the Canada side of the Falls back in 2007).

According to Reuters, during the recent polar vortex, "parts of the 176foot American falls were covered in ice and the area below theconservation area was frozen over. The cold weather caused the Niagarariver to form an 'ice bridge," and "large amounts of ice up river fromthe falls lead authorities to issue a flash flood warning for twoislands in the area."

Here are some scenic photos of NiagaraFalls from this year, which clearly show that the falls is covered inice and snow, but still flowing as usual.
