The Potomac River corridor at the meeting of Maryland, Pennsylvania, and West Virginia is defined by a dense network of early transportation routes. The Baltimore and Ohio Railroad and the Western Maryland Railway parallel the river, while the Chesapeake and Ohio Canal (Abandoned) traces the northern bank, marking the transition from water-borne commerce to the rail era. Small riverfront communities like Millstone and Cherry Run serve as anchors in a landscape dominated by dramatic ridges, including Tuscarora Mountain and Orchard Ridge.
