The Johnstown Flood (1889): A Rich Men's Dam Killed 2,200

On 31 May 1889, a wall of water and wreckage about 36 feet high rolled into Johnstown, Pennsylvania. It came from Lake Conemaugh, 14 miles upstream, held back by an old earth dam owned by the South Fork Fishing and Hunting Club, a private retreat for some of the richest men in America. More than 2,200 people died. Nobody was ever held legally responsible. This is the story of the Johnstown Flood: the warnings nobody believed, the telegraph operator who sent her last message, the engineer whose whistle saved lives, the fire at the Stone Bridge, and the question that still divides people today. Was it an act of God, as the club's lawyers argued, or the work of man?
