Potomac River crossings and historical land boundaries define this landscape at the border of Maryland and Virginia. The river corridor is dominated by the Chesapeake and Ohio Canal National Historical Park, where numerous islands such as Watkins Island and Clagett Island divide the waterway. On the Maryland side, the suburban expansion of Gaithersburg and North Potomac meets the preserved woodlands of Blockhouse Point and the Seneca Creek Greenway Trl.
