Hemlock Run, the small artificial stream that flowed through the cabin area was created by a small diversion dam. This dam was built upstream from the cabin area across Laurel Prong. Laurel Prong and Mill Prong join just below the President’s Cabin to form the Rapidan River which is a tributary of the Rappahannock River which flows southeast into the Chesapeake Bay.

Marker can be reached from Rapidan Road, on the left when traveling west.
