1955 Map of Portland

About this map

Kittatinny Mountain dominates the northern horizon of this landscape, where the Delaware River carves a dramatic passage between Pennsylvania and New Jersey. This mid-century update captures the region's complex infrastructure, from the heavy rail lines of Conrail following the riverbanks to the high-elevation path of the Appalachian Trail tracing the ridge. The settlement pattern is defined by river-crossing points like Portland and Columbia, while smaller hamlets like Vail and Polkville occupy the inland valleys. Industrial signatures including a Powerplant, Conveyors, and several Quarry sites sit alongside rural landmarks such as St James Ch and the Knowlton Frame Cem. The map documents the area during a period of transition, showing the intersection of long-standing agricultural communities and newer recreational developments like Camp Mohican and Lake Susquehanna.
