The day Niagara Falls ran dry

A view from the top of the de-watered Niagara Falls in 1969 in New York. Unearthed after 41 years by American Russ Glasson, they were taken by his mother and father in law and show when the famous waterfall was turned off for almost six months. For six months in the summer and autumn of 1969, Niagara’s American Falls were “de-watered”, when the Army Corps of Engineers conducted a survey of the falls’ rock face, concerned that it was becoming destabilized by erosion.
