It appears that cracks at the site were first noticed by a nine-year old child the day before the failure.
The 1954 Prospect Point Rockfall at Niagara Falls is shown in this amazing video below:
The rockfall left a large debris pile, which then became a tourist attraction in its own right – and was then removed by the U.S. army in 1969.
In the aftermath of the collapse, the Niagara Frontier State Parks Commission undertook blasting to remove rock left in a precarious position. Thereafter the site was deemed to be safe.
According to scientists, the rockfall had a mass of about 168,000 tonnes (185,000 tons). More history news on Strange Sounds and Steve Quayle. [Youtube]
