Johnstown Flood National Memorial

National Memorial — PA

The South Fork Dam failed on Friday, May 31, 1889, and unleashed 20,000,000 tons of water that devastated Johnstown, PA. The flood killed 2,209 people but it brought the nation and the world together to aid the "Johnstown sufferers." The story of the Johnstown Flood reminds us all, "...that we must leave nothing undone for the preservation and protection of our brother men."
