Frozen Niagara Falls

A few times in its history, Niagara Falls has frozen solid. And people, being naturally crazy and curious, have walked out over the unstable edge and snapped photos.

Here people walk on billows of ice that formed from the mist below the base of the falls.

An urban legend website debates when these photos were taken. Various claims have been made: 1848, 1890, 1911, and 1936. Another website, Environmental Graffiti, lays out the evidence, and says, "In 1912, an ice bridge broke apart as several people were crossing it, sending three to their deaths as the ice on which they stood plunged them into oblivion."
