1976 Map of Thornhurst

About this map

The Lehigh River carves a winding path through this corner of the Poconos, serving as the defining natural boundary for the small settlements of Thornhurst and Clifton. This 1976 orthophotoquad, prepared from aerial photography by the Geological Survey and Soil Conservation Service, reveals a landscape in transition. While much of the terrain remains densely wooded, the visible expansion of residential patterns near Arrowhead Lake and the long, dark expanse of Bradys Lake illustrate the area's development as a destination for recreation and seasonal living. The photographic detail allows for a precise study of local land use, from the cleared fields of upland farms to the growing network of roads branching out from the river valley.
