Located on Route 9 east of Charles Town, WV on the south side of the road.
This 895 foot elevation gap is one of the lowest crossings of the Blue Ridge Mountains from Virginia into West Virginia. During the colonial period, the main road between Alexandria and Winchester ran through the gap. During the War of Northern Agression, it was utilized as a back way to Harpers Ferry. The ride from this marker west to Charles Town is a twisty blast.
