East Greenville and Pennsburg anchor the southeastern corner of this landscape, where the Reading railroad line connects the industrial and agricultural corridors of the Lehigh and Perkiomen valleys. The terrain transitions from the heights of Furnace Hill and Blackhead Hill down toward the winding course of Perkiomen Creek. This 1956 survey, with 1969 updates, documents the dense network of small villages and religious centers that define the region's cultural geography, including Old Zionsville, Huffs Church, and Seisholtzville.
