The American side of the falls looked really rather spooky.
Multi-coloured lights helped create the alien-looking scene.
These beautiful pictures were taken on Monday evening.
The American Falls and Horseshoe Falls looked remarkably different in the bitter temperatures.
The falls also partially froze back in January when the US East Coast was hit by a 'polar vortex'.
Despite the conditions, the falls are still attracting numerous visitors keen to witness the incredible sight.
