About this map

Bald Eagle Mountain and Blue Mountain dominate this mid-century view of the Ridge-and-Valley province, where the Susquehanna River cuts through series of parallel ridges. The industrial heart of Central Pennsylvania is visible in the coal-region towns of Shamokin, Mount Carmel, and Ashland, while the agricultural valleys surrounding State College and Harrisburg show the extent of mid-twentieth-century development.

Major transportation and military corridors are a hallmark of this era, featuring the Pennsylvania Turnpike and extensive rail networks like the Penn Central and Reading. Significant military installations, including the Fort Indiantown Gap Military Reservation and the Mechanicsburg Naval Supply Depot, underscore the region's strategic importance. The map also documents extensive public lands across the ridges, such as Tuscarora State Forest and Rothrock State Forest.
