The famous falls were the subject of a social media debate as to whether the falls froze completely or not during the recent cold snap which affected some 240 million people in the US and southern Canada.

Niagara Falls hasn't frozen over, but it has become an icy spectacle, thanks to a blast of arctic wind and cold that blew around and froze the mist on surfaces and landscaping. Despite the urban legends, Niagara Falls doesn't freeze solid in the winter, tourism officials say. A section of the American Falls, one of three waterfalls that make up the natural attraction, has frozen. The Niagara River rapids and larger Horseshoe Falls continue to flow unimpeded.
