Frozen Niagara Falls? OK, partially frozen.

Frozen Niagara Falls came as a 'polar vortex' hit much of the US with extreme, low temperatures. Photographer Aaron Harris captured a partially frozen Niagara Falls for Reuters.

The 'polar vortex' hitting the U.S. with insanely-low temperatures has also offered the opportunity for some incredible photos — and now we've got some from the frozen Niagara Falls.

At the falls, where the temperature has been hovering in the low teens, Reuters photographer Aaron Harris took these shots of a partially frozen area of the falls on the U.S. side on Wednesday.

While there is some misinformation floating around, it's worth noting that the falls are not completely frozen over. You can see them flowing as usual on the live webcam.

 Still, the photos are worth taking a look at.
