1956 Map of Mount Vernon

Across the river in Maryland, the landscape remains markedly more rural, centered around the Marshall Hall amusement site and the agrarian stretches of Accokeek. The mapping reveals a complex riverfront economy and defense network, with Fort Hunt and Fort Washington facing each other across the water, and the established community of Gum Springs persisting as a focal point of local heritage. Waterways such as Piscataway Creek and Little Hunting Creek define the jagged shoreline, still largely used for navigation and transport as indicated by various landings and flats.
