The Potomac River forms a dominant boundary along the western edge of this Montgomery County landscape, mirrored by the structural legacy of the C & O Canal National Historic Park. Following the river's curve, the Towpath and the historic Chesapeake and Ohio Canal pass notable engineering features like the Monocacy Aqueduct at the confluence with the Monocacy River. The interior transitions from the river valley into a mosaic of rural settlements and agricultural corridors, including Poolesville, Dickerson, and Barnesville.
