In 2009, Russ Glasson found an abandoned shoebox with photos inside of a "dewatered" Niagara Falls. The Daily Mail has the story:
In June 1969, U.S. engineers diverted the flow of the Niagara River away from the American side of the falls for several months.
Their plan was to remove the large amount of loose rock from the base of the waterfall, an idea which they eventually abandoned due to expense in November of that year.
During the interim, they studied the riverbed and mechanically bolted and strengthened a number of faults to delay the gradual erosion of the American Falls.
The team, made up of U.S. Army Corp of Engineers, blew up their temporary dam in November 1969 and six million cubic feet of water once again thundered over the falls' sides every minute.Now, after lying unseen for more than four decades, a set of images showing the eerie calm at the American Falls that year have been unearthed by a man from Connecticut.
