These images show the US side of the three waterfalls straddling the border between Canada and America after they were frozen in time by the Arctic chills.
In these pictures taken on Wednesday the water can be seen after it has been replaced by icicles dangling from its precipice. The Midwest of America, home to the Niagara Falls, has experienced temperatures plummeting as low as -37°C.
Yet the freezing weather failed to deter visitors eager to see the effects of the polar vortex, which affected approximately 240 million people, on the falls.
Tourists were out in force with their cameras yesterday at the Prospect Point at Niagara Falls State Park and Rainbow Bridge where frozen mist and solid ice was visible below.
The weather conditions produced by this polar vortex have been so severe that even polar bears at the Lincoln Park zoo in Chicago were brought inside as the weather dropped to a record low of -26°C.
Residents were warned their skin may freeze if they leave their homes when wind and Central Park broke a 118-year-old record when the temperature dropped to -15°C.
But residents in the US and southern Canada can lookforward to a reprieve from the subzero conditions later this week, when the frigid air and polar vortex departs and a far-reaching January thaw begins, AccuWeather.com have predicted.
