I have seen this river at Harpers Ferry, West Virginia. It's beautiful.

Wikipedia: The Shenandoah River is a tributary of the Potomac River, 55.6 miles long with two forks approximately 100 miles long each, in the U.S. states of Virginia and West Virginia. The principal tributary of the Potomac, the river and its tributaries drain the central and lower Shenandoah Valley and the Page Valley in the Appalachians on the west side of the Blue Ridge Mountains, in northwestern Virginia and the Eastern Panhandle of West Virginia.
