The Monongahela River carves the eastern boundary of this industrial and residential landscape south of Pittsburgh, where the topography transitions from the river valley to the hills of Jefferson Hills and Baldwin. This 2010 survey shows the intense infrastructure supporting the Mon Valley, including the Allegheny County Airport and the concentrated riverfront settlements of Glassport, Clairton, and Elizabeth.
