The Mason and Dixon Line serves as a primary geographic anchor on this survey, marking the intersection where Pennsylvania, Maryland, and Delaware meet. The landscape is defined by the converging drainages of Big Elk Creek and the West Branch Christina River, which supported early industrial pockets like Elk Mills. To the southeast, the growing footprint of Newark is evident, centered around the University of Delaware and the heavy rail corridors of the Baltimore and Ohio and Penn Central railroads.
