When engineers made the American falls run dry in 1969, Chris Hemedinger was there.
Just an infant at the time, he sat in a stroller near the brink while his father, Duane, filmed the scene at Niagara Falls with a Super 8 camera.
The film shows the rocky landscape of the American falls and onlookers gathered to take in the sight.
Chris Hemedinger put the video on YouTube in 2011.
"I figured it contained footage of a scene that not many people know about or have seen before," he wrote in an email. His family lived in Tonawanda at the time it was shot. He now lives in Raleigh, N.C., and works for a software company in nearby Cary.
Here's the video:
He said the footage was shot in August 1969. His father had returned a couple months prior from serving in Vietnam; Duane Hemedinger served in the Air National Guard out of the Niagara Falls base.
The film's final images include Chris, who was about 1 year old, and his mother, Sue.
Chris Hemedinger said he still has family in the area, including his parents, who still visit Niagara Falls on occasion.
And just a note -- the song playing in the video is "Cool Water" by Sons of the Pioneers.
