About this map

Industrial centers and river valleys anchor the landscape of Western Pennsylvania in this late-1960s revision. The confluence of the Allegheny River and Monongahela River marks the core of Pittsburgh, while the Youghiogheny River and Kiskiminetas River serve as arteries for coal and steel towns like Mc Keesport, Vandergrift, and Ford City. The map documents a mature transportation network where the Pennsylvania RR and Baltimore and Ohio RR parallel historic corridors like the Lincoln Highway and the Pennsylvania Turnpike.

Beyond the urban corridors, the Allegheny Mountains rise to the east, defined by the prominent Laurel Hill and Chestnut Ridge. This period highlights the development of regional flood control and recreation, visible in the Conemaugh River Reservoir and Loyalhanna Lake. From the northern reach of Punxsutawney to the southern hub of Connellsville, the map captures the transition from heavy industrial riverfronts to the highland ridges of the Rothrock State Forest.
