The North Branch Potomac River defines the state boundary between Maryland and West Virginia, carving a winding path through a landscape of prominent ridges like Irons Mtn and Warrior Mtn. This area is characterized by narrow hollows and high ground, including the distinctive Death Valley and Frog Hollow. Parallel to the river, the Chesapeake and Ohio Canal National Historical Park preserves a critical piece of 19th-century transportation history, now shadowed by modern CSX Transportation rail lines.
