About this map

The Allegheny National Forest dominates this mid-century portrait of northwestern Pennsylvania, a region defined by its deep timberlands and the legacy of the American petroleum industry. Centered on the city of Warren, the map captures the vast industrial landscape of Oil City and Titusville as they appeared following the 1957 photogrammetric surveys. The hydrology of the area is prominently marked by the Allegheny Reservoir and Tionesta Lake, providing a clear look at the water management and recreation infrastructure of the era.

Transportation networks including the Penn Central and Erie Lackawanna railroads crisscross the plateau, connecting established mountain towns like Kane, Ridgway, and Saint Marys. Extensive state forest lands such as Susquehannock State Forest and Elk State Forest are documented alongside numerous state parks, illustrating the balance between extraction and conservation in the late 1950s and 1960s. Genealogists will find many small settlements and mountain junctions preserved here, from Marienville to Port Allegany.
