Cacapon
Cacapon is a Shawnee name meaning “medicine water.” This shallow river winds among the Appalachian ridges to meet the Potomac. Its headwaters, near Mathias, are known as the Lost River: the stream disappears underground at the Sinks and reappears near Wardensville as the Cacapon. Farther downstream it receives the North River, its largest tributary, before continuing through the mountain valleys.
