Industrial Geography

The main iron and steel industries of the U.S.A. are located in Pittsburgh and the Great Lakes region, including cities like Cleveland, Gary, and Detroit. These regions developed due to availability of iron ore from the Mesabi Range, coal from the Appalachian region, and water transport routes through the Great Lakes. The industries grew with strong markets, skilled labour, and excellent transport networks. Pittsburgh is also known as the "Steel City" for its long history in steel production.
