The Potomac River corridor south of Darnestown serves as the primary focal point of this mid-century survey, illustrating the complex riverine boundary between Maryland and Virginia. The Chesapeake and Ohio Canal parallels the river's northern bank, passing landmark features like Blockhouse Point and the village of Seneca. On the Virginia side, the landscape is defined by the headwaters of Sugarland Run and the presence of the Leesburg Turnpike passing through Dranesville.
