The Monongahela River carves a deep industrial corridor through this landscape, anchoring steel-town centers like Glassport, Clairton, and Dravosburg. By the early 1960s, the plateaus above the river show significant suburban expansion into West Mifflin and Brentwood, while the southern reaches of the map near Gastonville and Finleyville retain a more rural character. This survey highlights the region's diverse economic footprint, from the specialized research at the U S Bureau of Mines Experimental Sta and the logistical hub of the Allegheny County Airport to the numerous mines and slag dumps lining the riverbanks.
