Remnants of the Georgetown Inclined Plane along the Chesapeake and Ohio Canal, Washington DC.
This was once the longest of its kind, with a forty foot drop to the Potomac River.
The first boat passed over the plane in 1876, and 1,918 boats went over it in 1878.
This plane used counterweights but was originally built to operate on Canal water power with a turbine.
Use of the plane declined, and it was not repaired after the 1889 flood.
The Georgetown Branch of the Baltimore and Ohio Canal was established and cut through the middle of it by 1909.
