Niagara Falls frozen 2015: American Falls reduced to icicles as polar vortex hits East Coast
The Niagara Falls has frozen for a second time as the East Coast shivers in record-breaking sub-zero temperatures.
The American Falls has been reduced to icicles and a trickle by the polar vortex on Thursday, February 2015.
Incredible pictures show Niagara Falls partially frozen as chilly temperatures continue to bring snow and ice across the US-Canada border.
Similar images emerged last year when the falls, which usually see the passage of 567,811 liters per second, partially froze twice in a few weeks as temperatures fell to a record-breaking low.
Pictures taken this year show some parts of the falls and surrounding areas covered in sheets of ice.
