Industrial centers and river valleys anchor this 1951 Army Map Service study of Eastern Ohio and Western Pennsylvania. The heavy industry of Canton and Pittsburgh is linked by a dense network of transit, including the Pennsylvania RR and the Baltimore & Ohio RR. The landscape is defined by the winding course of the Ohio River and the complex drainage of the Tuscarawas River, which by mid-century was increasingly managed through a series of massive flood control projects. Numerous basins like Tappan Reservoir, Clendening Reservoir, and Senecaville Reservoir appear as established features of the regional topography. This map documents a post-war period of high activity, where historic thoroughfares like the Lincoln Highway and National Road intersected with the rising dominance of steel manufacturing and rail transport in the Appalachian foothills.
