About this map

The Potomac River bisects this mid-century landscape, separating the rural tobacco lands of Maryland from the emerging military presence in Virginia. On the Virginia shore, the U S Naval Proving Ground dominates the peninsula, centered around Dahlgren and the coastal defenses near Machadoc Creek. This region shows a transition from a traditional agrarian economy to one influenced by federal infrastructure, evidenced by the proximity of established county seats like King George to modern naval installations.
