1911 Photo of Niagara Falls

This interesting set of photographs of a frozen Niagara Falls circulates via email and has been posted to various blogs and online forums. There is no reason to doubt the authenticity of the photographs. While the falls almost never freeze solid, it is not uncommon for mounds of ice to form a thick crust that covers the running water beneath. Strange and beautiful ice formations can be formed as mist and falling water freeze over.
