== Why Pittsburgh is the steel capital of PA == 

 Pittsburgh is the steel capital of PA for more reasons than just coal. First, it was easy to ship in iron ore from the Great Lakes by way of canals and rivers. Second, bituminous coal is plentiful.  Third, access to the "three rivers" Ohio, Allegheny, and Monongahela Rivers provided a way to transport the finished steel to the Mississipppi and into the growing country i.e. "Mid West".  Remember, America was moving westward at the same time Pittsburgh was becoming a major steel producer. The combination of ore, coal and easy transportation made the Pittsburgh area ideal.
