Great Falls Park - History

History

Native American petroglyphs have been discovered within the park on cliffs overlooking Difficult Run.{ }

The Patowmack Canal, which George Washington partially funded, was a one-mile (1.6 km) bypass canal that began operating in 1785 to give small barges the opportunity to skirt around the falls and to distribute manufactured goods upstream and raw materials downstream. The park visitor center has the bottom portions of two wooden canal lock gates excavated in the 1980s from the canal. The gates survived from at least the 1830s and were found during restoration projects on stonework which were erected for the canal locks. Stonemason marks found on the stones are unique to each artisan and are identical to some found in foundation stones of the White House and the U.S. Capitol.

During the construction of the canal, blasting powder, which at the time was essentially gunpowder, was used to blast through solid rocks. This is one of the first known examples of blasting powder being used for engineering purposes anywhere in the world. The canal was never a profitable enterprise. With the completion of the Chesapeake and Ohio Canal on the opposite side of the river, and the oncoming age of railroads, the project was abandoned in 1830. The canal is a Civil Engineering Landmark as well as a Virginia Historic Landmark. Along the trails, the ruins of the small town of Matildaville, Virginia can also be found.

Between 1906 and 1932, the Great Falls and Old Dominion Railroad and its successor, the Washington and Old Dominion Railway, operated an amusement park (trolley park) at the falls. Located at the end of an electric trolley line that began in Georgetown, Washington, D.C., the park contained picnic grounds, a dance pavilion, and a carousel. In the evenings, a searchlight illuminated the falls. The park continues to provide picnic grounds and a visitor's center but the carousel that operated between 1954 and 1972 was destroyed by a flood caused by Hurricane Agnes.

The George Washington Memorial Parkway was developed to ensure the easy linkage of George Washington's most visited places. Great Falls Park was a part of the Northern Virginia Parks system and was transferred to the NPS in 1966. A proposed bridge to span the falls was also considered but, due to a strong lobby to eliminate additional bridges over the Potomac and concerns over environmental impacts, the project was never undertaken.
