The Carnegie Steel Ohio works on the banks of the Mahoning River around 1910.
This mill became part of U.S. Steel later and was closed in 1979.
Starting with the “Black Monday” in September 1977, the closure of Youngstown Sheet And Tube, the once thriving valley of steel was gutted within just one decade.
A recommendable book telling the story of this decline is John Russo’s “Steeltown U.S.A. – Work And Memory In Youngstown” published by the University Press Of Kansas.
