The industrial and agricultural heart of Lehigh County is defined here by the winding Lehigh River, which separates the townships of North Whitehall and Allen. In the mid-1960s, the region was characterized by the intensive excavation of its namesake industry, evidenced by the Dewey Heights Quarry and numerous other unnamed pits near Cementon and Egypt. These operations are interspersed with established community landmarks like the Mary Immaculate Missionary College and several historic burial grounds, including Old Union Cem and Egypt Cem.
