1908 Map of Seneca

About this map

The Potomac River corridor dominates this 1907 survey, illustrating the complex transportation network shared between Maryland and Virginia. The Chesapeake and Ohio Canal parallels the riverbank, passing through key crossings like Whites Ferry and Edwards Ferry, while islands such as Harrison Island and Van Deventer Island divide the waterway. Inland, the agricultural and industrial landscape of Montgomery County is defined by the Baltimore and Ohio RR and its Metropolitan Branch, which connects established settlements like Poolesville, Germantown, and Barnesville Station. This period shows a transition from river-based transport to rail, with the Southern Ry (Bluemont Branch) carving through the Virginia side near Ashburn. Topographic details reveal the drainage patterns of Great Seneca Creek and Dry Seneca Creek, which carve through the uplands before reaching the Potomac at Seneca.
