The U S Naval Air Development Center dominates the central landscape of this 1952 study, marking a period of significant military and suburban expansion in the Philadelphia suburbs. This survey captures the transition of the region from agrarian townships like Warwick and Northampton into a dense network of residential developments and industrial centers. In the southern portion, the spiritual and educational center of Bryn Athyn is visible near the banks of Pennypack Creek, including the Bryn Athyn Academy and The Chapel of the New Lords.
