Perkiomen Creek and its many tributaries, including Unami Creek and Swamp Creek, define the rolling Montgomery County landscape shown here. The area is characterized by a dense network of early settlements and historic church sites, including the Old Goschenhoppen Cem near Woxall and the Salford Mennonite Cem in Harleysville. The elevation is punctuated by Spring Mountain near Delphi, while the Green Lane Reservoir provides a major geographic anchor to the northwest near Red Hill and Green Lane.
