The frozen waterfall
Considering the sheer size of Niagara Falls, the notion that the river would freeze might seem ridiculous, but it’s actually a lot more common than you might think. Throughout history, large parts of the river and falls had become frozen due to extremely low temperatures.
However, with so much water flowing every minute, Niagara Falls has never completely frozen over. Still, with several inches of ice sitting atop a seemingly infinite pool of frigid water is a mightily impressive feat, even for Mother Nature. You might catch a glimpse of miniature glaciers in the river if you visit Niagara Falls in January.
