How cold is too cold?

Tolerances vary from person to person. For some, it’s too cold if they can see their breath. For others, anything below freezing where precipitation comes in the form of a beautiful white snowfall is too cold. And for the truly brave out there, nothing short of the polar vortex is considered too cold.

But what about when it gets so cold that it can freeze running water? That’s exactly what happened to the majestic Niagara Falls. According to weather.com, a massive cold front has hit the Great Lakes region and the waterfalls between Canada and New York have become frozen.

Water still flows underneath the ice, so it’s not as if “hell has frozen over,” but it’s an awesome sight to be sure.
