The Potomac River serves as the central artery of this mid-1940s landscape, marking the historic boundary between Maryland and Virginia. Along its northern bank, the Chesapeake and Ohio Canal winds past landmarks like Blockhouse Point and a series of river islands including Watkins Island and Katie I. The Maryland side is defined by the drainage systems of Seneca Creek and Muddy Branch, supporting small upland settlements like Quince Orchard, Darnestown, and Travilah.
