Very rare photos (Frozen Niagara Falls)

This image is displayed on the Niagara Falls Public Library website with the title "American Falls Frozen over with People on the Ice". According to information associated the image, it began circulating on the Internet in 2003 but the original source and date is not known.

The image is also featured on Niagara Falls live.com, and its position in the text suggest that it may be future to show an event in 1848 when the river really stopped flowing completely for a few hours due to an ice jam upstream. Though, it is unclear if the image depicts the actual event describe, or is only used as a general illustration of an ice bridge.

This image was apparently derived from an original color postcard titled "Cave of the Winds in Winter Niagara Falls" which was mailed in August 1911. Accurately when the image was created is unclear. The image is also featured on the website of Ellis House, a Bed and Breakfast at Niagara Falls.

This image seems to be a cropped version, of a photograph titled "American Falls frozen over" that was taken in 1936. Comments with the uncropped image explain "The miraculous result of a cold winter, the American Falls totally froze in 1936. Notice the tiny human forms at the base of the Falls giving an idea of the density of the ice."

This image is also included on the Niagara Falls Public Library as well as titled "Great mass of frozen spray and ice-bound American Falls Niagara", by a date of 1902. It originally formed part of a stereo image, a popular medium at the time.
