The Monongahela River carves a deep industrial corridor through this 1960s landscape, bordering the heavy manufacturing centers of Glassport, Clairton, and McKeesport. The map illustrates the region's post-war transition, where traditional river-and-rail infrastructure meets expanding residential suburbs like Pleasant Hills and Brentwood. Significant land-use features include the Slag Dump and Settling Basin near West Mifflin, highlighting the massive scale of the local steel industry's waste management during its peak years.
