Niagara Falls Dried Up!!

Niagara Falls

In June 1969, U.S. engineers diverted the flow of the Niagara River away from the American side of the falls for several months.

American Falls

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.

Dried up

Russ Glasson recently stumbled across the pictures, which were taken by his in-laws, and had been left in an old shoebox in their garage for over four decades.
