The confluence of the Allegheny River and Monongahela River forms the Ohio River at the very edge of this 1960 revision, highlighting the industrial heart of western Pennsylvania. The urban landscape is dense with institutional history, featuring the Western State Penitentiary on the riverbank and the Allegheny Observatory overlooking Riverview Park. To the west, the winding path of Chartiers Creek serves as a geographic anchor for numerous boroughs and neighborhoods, including McKees Rocks, Ingram, and Carnegie.
