In June 1969 the U.S. Army Corp of Engineers diverted the flow of water over the US side of Niagara Falls causing it to dry up for several months in an effort to remove loose rocks from the base of the waterfall. The plan became too expensive, so they returned the flow of water over the falls in November 1969.
In 2009 Russ Glasson found a bunch of amazing photos his in-laws shot of the dry falls in a shoebox. Here’s an interview CNN did with Russ about the photos he discovered which are now being shared around the world.
