Allentown dominates the eastern edge of this landscape, its urban grid and corporate boundaries reaching toward suburban clusters like Sterlingworth and Dorneyville. The mid-century development patterns are evident in the sprawling Crest Plaza Shopping Center and residential expansion near Ancient Oaks, while the western reaches retain a more varied landscape of small settlements and industry. The industrial heritage of the region is anchored by the Lock Ridge Park and Furnace Museum near Alburtis, a reminder of the iron-producing past of the Lehigh Valley.
