It’s May, 30th 1889, and the South Fork Dam in Western Pennsylvania is in danger. After nearly a month of hard rain, eight inches have fallen in one day, filling the lake behind the dam to capacity.

It’s threatening to break, which would unleash 20 million tons of water on the people in the valley below, including everyone living in the steel city of Johnstown.
