Useless But Compelling Facts – January 2008 Answer

Last issue we asked if you can tell us how many times, since official records have been kept, Niagara Falls has frozen over completely. Congratulations to Shari Gottesman, one of our loyal readers and a past prize winner, who very quickly responded by correctly telling me that the flow of water is too great for all of Niagara Falls to completely freeze—although there have been ice bridges that have formed and the American Falls were stopped six times since records have been kept because of ice jams. There are claims that the Falls completely froze in 1911, and in 1912, people were allowed to walk across the ice bridges even though water was still flowing underneath. Unfortunately, the bridges broke and the practice halted. Congratulations Shari, and I’m going to figure out a bigger prize for your loyalty!
