The Massanutten Mountain System in Virginia, lying between the Blue Ridge on the east and the Alleghenies on the west, divides the Shenandoah Valley into two parts for a distance of about 49 miles. Along the western base of the Massanutten mountains meanders the beautiful north fork of the Shenandoah River. Equally lovely and equally meandering, the south fork of the Shenandoah flows along the eastern base of the mountains.
