1955 Map of Portland

About this map

The Delaware River carves a dramatic passage through Kittatinny Mountain at The Gap, anchoring a landscape defined by sharp elevation changes and the historical movement of goods and people between Pennsylvania and New Jersey. On the Jersey side, the townships of Knowlton, Blairstown, and Pahaquarry are marked by early industrial and transportation nodes like the Hainesburg Sta and the Old Railroad Grade. Industrial activity is evident at the Powerplant and various Gravel Pits, contrasting with the recreational development of the Delaware Water Gap National Recreation Area and the high-elevation Sunfish Pond. Genealogists will find interest in several established burial grounds, including St Vincent Cem and Knowlton Frame Cem, while the Appalachian Trail traces the ridgeline near Mt Tammany, overlooking the twin riverside settlements of Portland and Columbia.
