Frozen Falls: Niagara Falls before & after freezing

The low temperatures across Canada (about -14 degrees Celsius) include the Niagara Region in Ontario, where the greatest tourist treasure shared by Canada and the U.S., Niagara Falls, has once again frozen over. The icy spectacle presents a very different picture for some of the site's annual 20 million visitors: Whoever sees the falls now, while they're frozen, can enjoy an added dimension to the existing wonder of nature.
