South Mountain and Furnace Hill define the northern highlands of this mid-century survey, where the borders of Berks, Lehigh, and Montgomery counties meet. The landscape is a network of small, established villages including Old Zionsville, Bally, and Hensingersville, many of which developed along early corridors like the Kings Highway. In the southeast, the urban centers of East Greenville and Pennsburg show significant detail, including the grounds of the Perkiomen Preparatory Sch and the New Goshenhoppen Ch. The Reading railroad line cuts through these towns, following the valley of the Perkiomen Creek. Cultural updates from the 1970s are visible in purple, highlighting the development of the Green Lane Reservoir and the expansion of residential clusters near Perkiomen Heights. This sheet captures a transition from traditional agricultural settlements and isolated country churches like St Peters Ch to modern infrastructure like the Drive-in Theater near Shimerville.
