PowerPoint: Niagara Falls - Photo or Hoax?

  1. 1. Rare Photo Or Hoax
  2. 2. Although we don’t really have any doubts that the photograph in question is agenuine image produced at a time when much of the water around the AmericanFalls was frozen, we don’t know the original source of this picture and thus can’tverify the year in which it was taken. Although the text that accompanies theimage in email forwards usually states that the photo dates from 1911, othersources assign a variety of different dates to it. Much of the Niagara Riveraround the falls was frozen in 1912, which resulted in a tragic accident when anice bridge across the river broke free from its shoring as several people were traversing it. Three people were unable to make it back to shore in time andwere killed as the loosened ice plunged down the river. CLICK here for information (",)
  3. 3. What are the “Niagara Falls”? Niagara Falls (actually the collective name for a set of three waterfalls along the Niagara River that forms the border between New York and Ontario: the American Falls, The Bridal Veil Falls and the Canadian/Horseshoe Falls) is the celebrated natural phenomenon that has awed generations of honeymooners. Although it may seem astounding to contemplate, the tremendous volume of rushing water (hundreds of thousands of gallons per second)l that is Niagara Falls does “freeze” from time to time, although not quite “completely” as suggested in the photograph.

  4. 4. Does the Falls freeze in Winter? The Niagara River handles 212,000 cubic feet of water per second. The average depth is approximately 16 feet with a flow rate of 4 to 8 miles per hour. The Niagara River does not freeze over. The Falls of Niagara and the river below the Falls does not freeze either. The volume of water going over the Falls, the depth and speed of the water below the Falls also precludes freezing. The water will not be stopped or frozen solid. 
  5. 5. Only once! During occasional periods of prolonged cold weather falling water and spray from Niagara Falls may freeze into ice formations, and ice mounds or flows may form in the Niagara River (sometimes creating ice bridges that stretch across the width of the river), but only once in recorded history has freezing weather actually stopped water from flowing over the falls. This instance occurred in March 1848 when a preponderance of ice above the falls reduced the flow of water over the falls to a trickle. 
