It's so cold in America, Niagara Falls has frozen over!

North America is experiencing its harshest cold snap in 24 years, so cold in fact that Niagara Falls has frozen over.

Photos of the falls on the American and Canadian sides have become a world attraction in recent days as wind chills there fell to as low as minus 14 degrees, according to the National Weather Service.

And it’s unlikely the falls will thaw anytime soon: freezing conditions are expected to remain through the rest of the week.

A quick look at the amazing pictures.
