About this map

The Allegheny National Forest dominates the heart of this North Central Pennsylvania landscape, a region defined by the deeply dissected Allegheny Plateau and the winding course of the Allegheny River. Revised in 1969, this survey captures the industrial and natural geography of the region just as I-80 was reshaping connectivity across the southern tier. The map highlights the vast timber and wilderness preserves of the Susquehannock State Forest and Elk State Forest, punctuated by established industrial hubs like Warren, Bradford, and Oil City.

The railroad network remains extensive, showing the operational lines of the Penn Central, Erie Lackawanna, and Baltimore & Ohio during a transitional era for American rail. Notable water management features, including the Allegheny Reservoir and Tionesta Reservoir, illustrate mid-century infrastructure projects designed to control the watershed of the Clarion River and West Branch Susquehanna River.
