Niagara Falls Freezes Over
A sight to behold if you can stand the cold.
The extreme weather in North America and Canada have provided plenty of photographic opportunities but those people visiting these waterfalls have had a sight to behold, that is if they can stand the cold, because parts of Niagara Falls have become frozen.
Braving temperatures as low as -19 with the wind chill, these visitors have been rewarded with spectacular sights and a photo gallery to tell the tale.
Images of water turning ice to before it reaches the bottom creating an ice jam and subsequent flooding on two islands were also captured.
The US and Canada have been suffering from a Polar Vortex that has brought freezing air and Arctic temperatures down past -60 in parts. Temperatures are expected to rise this week with a thaw that millions will be grateful for.
It's predicted the cold could switch to relative warm of 12 degrees celsius an extreme change from what the US and Canada are currently experiencing.
