Dam 5, C&O Canal towpath along the Potomac River. Built in 1835, the dam raised the river level enough to fill 22 miles of the canal. It's a great place to stop and rest after a day of biking the towpath!
Potomac River, C&O Canal
Dawn along the C&O Canal towpath. The Potomac River is still, just above Dam 5. This is looking south into West Virginia, from Maryland.
