Slag Pile Annie is the name of a ghost reputed to haunt the former Jones and Laughlin Steel Corporation mill in Pittsburgh, Pennsylvania. According to the story, she appeared as a rough-looking woman wearing a red bandana, [1] working or just standing in a remote and hard-to-access part of the mill. The steelworkers who warned her of danger did not know she was a ghost, until she replied, "I can't get killed, I'm already dead." [2] [3] [4]
The tale may have developed from the true experiences of women working dangerous jobs in the Pittsburgh steel mills during World War II. [1]
