Niagara Falls in Winter, c. 1900

Historical Context
While Niagara Falls does not freeze in winter, an ice bridge forms at the bottom of the falls with water flowing underneath.  It has been reported that up to eighty feet of thick ice has formed across the base of the falls in the past.  Until 1912, visitors were actually allowed to walk out on the ice bridge; however, on February 4, 1912, the ice broke up, and three tourists died.
