Edgewood Proving Ground dominates the southern landscape of this coastal Maryland region, where the Gunpowder River and Bush River meet the Chesapeake inlets. This 2011 survey captures a complex suburban and industrial corridor defined by heavy transportation infrastructure, including the I-95 and the historic B And O RR. The transition from old industrial sites like Harford Furnace to modern residential developments like Abingdon and Joppatowne is evident across the terrain.
