1977 Map of Indiantown Gap

About this map

Indiantown Gap serves as the focal point of this 1970s orthophotograph, where the dense woodland of the Appalachian ridges meets the developing valley of northern Lebanon County. The imagery, produced by the Geological Survey in cooperation with the Soil Conservation Service, provides a detailed visual of the land use patterns surrounding the gap. Small crossroads settlements like Harper Tavern, Ono, and Bordnersville are clearly visible, tucked between expansive agricultural fields and the burgeoning interstate highway corridors. To the west, the waters of State Memorial Lake stand out against the terrain, while the parallel ridges of Blue Mountain, Second Mountain, and Sharp Mountain dominate the northern landscape. This perspective captured in 1977 documents the transition from traditional rural farmsteads to a modern transportation hub near Lickdale.
