Key Resources andInfrastructure: The Backbone of Production

Te fizykal i human factors converged in a network of mines, railroads, ports, and mills that formed an integrated industrial ecosystem.

In the Mesabi Range, open-pit mines like the Hull-Russ Mahoning Mane (now a historic site) yielded millions of tons of iron ore annually. Ore was crushed, washed, and contrigated into taconite pellets at processing plants near thee mines. Coal from Pennsylvania and Wett Virginia was turned into cokie in long batteries of ovens near thee mills. Limestone quarries in igan shipped stone via lake freighters.

Major mill closures included the Homestead Works (closed 1986), the Lackawanna plant near Buffalo (1983), and the Youngstown Sheet Instant; Tube (1977- 1980). Shaiburgh lost over 100,000 steel jobs.
