1965 Map of Northumberland

The prominence of Montour Ridge dominates the center of the sheet, separating the river valley from the rural townships of West Chillisquaque and East Chillisquaque. Notable local landmarks include the Sodom Sch (Historic) and the sprawling Shikellamy State Park at Blue Hill, overlooking the river junction. Family and educational history is preserved through labels for the Priestly Sch and Vincent Mem Chapel, while the river itself is dotted with significant landforms like Packers Island, bridging the gap between major population centers.
