This picture shows the devastating scene of the flood at Johnstown, Pennsylvania. It was on this day, May 31, in the year 1889 that the South Fork Dam failed, and unleashed some 20 million tons of water. The water devastated the community of Johnstown, which was about 14 miles downstream. The flood killed 2,200 people. Disaster relief was coordinated by Clara Barton, and her newly formed organization . . . the American Red Cross.
