About this map

The Potomac River carves a winding path through the heart of this mid-1980s landscape, serving as the jurisdictional boundary for Maryland, Virginia, and West Virginia. This region is defined by its significant historical preserves, including Antietam National Battlefield and Harpers Ferry National Historical Park, where the Shenandoah River meets the Potomac. The map illustrates a period of significant suburban expansion along the Interstate 270 corridor, connecting Gaithersburg and Rockville to the rural north.

Strategic infrastructure and transport networks are prominent, from the massive Fort Detrick complex in Frederick to the historic C & O Canal National Historical Park tracing the riverbanks. The Baltimore and Ohio RR and Western Maryland RR provide a look at the rail economy of the era, while the rising waters of the Triadelphia Reservoir and the ridgelines of the Blue Ridge and Catoctin Mountain frame the diverse topography of the Piedmont and the Valley.
