The winter storm that has blanketed parts of Midwestern and Northeastern United States in snow has now brought the rushing waters of Niagara Falls to a halt in places.
Stunning photos show how the waterfall has been transformed into a frozen wonderland.
Parts of the waterfall still continue to flow, but are surrounded by huge blocks of ice.
