The North Branch Potomac River serves as the winding boundary between Maryland and West Virginia, anchoring a landscape where aviation and industrial history meet. The Allegany Ballistics Lab occupies a significant portion of the riverbend near Pinto, reflecting the region's mid-century role in defense and aerospace engineering. This modern survey tracks the evolving suburban footprint of Cresaptown, Bel Air, and Bowling Green, while maintaining the corridor of the Chesapeake and Ohio Canal National Historical Park along the northern banks.
