Difficult Run

The Madeira School (simply referred to as Madeira School or Madeira) is an elite, private, day and boarding college-preparatory school for girls in McLean, Virginia, United States. It was established in 1906 by Lucy Madeira Wing.

Bear Island is an island located in Potomac, Montgomery County, Maryland between the Potomac River and the Chesapeake and Ohio Canal near the Great Falls. It is managed by the National Park Service as part of the Chesapeake and Ohio Canal National Historical Park and is co-owned by The Nature Conservancy. One of its most popular attractions is the Billy Goat Trail. Pets are not allowed on Bear Island, nor is smoking.

Mather Gorge is a river gorge south and just downriver of Great Falls in the state of Maryland bordering Virginia. The Maryland land side of the gorge is Bear Island, part of the Chesapeake and Ohio Canal National Historical Park, and the Virginia side is part of Great Falls Park. Both parks are National Park Service sites. The gorge is named after Stephen Mather, the first director of the National Park Service. The gorge is cut by the Potomac River and is, for the most part, lined on both sides by cliffs. Towards the southern end of the gorge, the cliffs become tree-lined bluffs as the gorge widens out into the wider and larger Potomac Gorge. At Little Falls, the Potomac River crosses the Fall Line as it leaves the Appalachian Piedmont and enters the Atlantic Coastal Plain. Hiking is a common activity with many trails along and near the gorge. On the Maryland side, in the C&O Canal National Historical Park, Section A of the Billy Goat Trail follows the gorge—from below Great Falls to above the Anglers Inn river put-in. The River Trail in Great Falls Park follows the gorge on the Virginia side. It is also a popular rock climbing attraction as the cliff heights and terrain lend themselves well to top rope climbing. Generally, most of the rock climbing occurs on the vertical cliffs of the Virginia side of the gorge, below the Observation Decks and above the 90 degree river bend. Whitewater kayaking and canoeing is also very popular within the gorge. From Great Falls to the Difficult Run Rapids (Maryland Chute, Virginia Chute, and Center Chute), the gorge contains Class I to Class VI whitewater rapids.

The Patowmack Canal, sometimes called the Potomac Canal, is a series of five inoperative canals located in Maryland and Virginia, United States, that was designed to bypass rapids in the Potomac River upstream of the present Washington, D.C., area. The most well known of them is the Great Falls skirting canal, whose remains are managed by the National Park Service as it is within Great Falls Park Virginia, an integral part of the George Washington Memorial Parkway.The first section of the canal opened in 1795, and the canal ended operations in 1828.

The Billy Goat Trail is a 4.7-mile (7.6 km) hiking trail that follows a path between the C&O Canal and the Potomac River within the Chesapeake and Ohio Canal National Historical Park near the Great Falls in Montgomery County, Maryland. The trail has three sections: Section A, the northernmost, is 1.7 miles (2.7 km); Section B is 1.4 miles (2.3 km); and Section C, the southernmost, is 1.6 miles (2.6 km)

Olmsted Island is a small island in the middle of the Potomac River in the U.S. state of Maryland, near Great Falls which is a part of C & O Canal National Historical Park, located across the river from Great Falls Park. It is a part of Potomac, Maryland. Named for Frederick Law Olmsted, Jr., the landscape architect and preservationist whose famous father designed New York's Central Park, the small island is a bedrock terrace forest that supports rare, threatened and endangered plant species.The island is very rocky and has steep cliffs that face the river, where it has been eroded over time. It also has trees and vegetation. One might also spy a heron, small lizard or wild goose here. The total area of the island (estimating from calibrated satellite footage) is no more than 0.2 square kilometers. A fenced-in wooden tourist walkway winds along the southern part of the island. For the purpose of protecting the island's natural wildlife, visitors are not allowed to leave the tourist walkway. The tourist walkway eventually ends in a scenic overlook platform (see images 1 and 2) that has a beautiful view of the Great Falls of the Potomac River. "Hurricane Agnes washed away all the woody shrubs and trees in 1972," says R. Harrison Wiegand, a regional ecologist for the Wildlife and Heritage Service of the Maryland Department of Natural Resources. "The next big flood will wash them away again. The floods constantly change things. You may see a rare species in one area, then the floods will come through and wash it out. Some other plants will grow there instead. This is one of the most biologically diverse habitats within the whole national park system."The trail leading to Olmsted Island is handicapped accessible and has wheelchair ramps, but dogs are not permitted.

Great Falls is a series of rapids and waterfalls on the Potomac River, 14 miles (23 km) upstream from Washington, D.C., on the border of Montgomery County, Maryland and Fairfax County, Virginia. Great Falls Park, managed as part of George Washington Memorial Parkway, is on the southern banks in Virginia, and Chesapeake and Ohio Canal National Historical Park parkland is along the northern banks of the river in Maryland. Both are operated by the National Park Service. The Potomac and the falls themselves are legally entirely within Maryland, with the state and county boundaries following the south bank of the river. Scenic views are offered on both the Maryland side and the Virginia side. The Billy Goat Trail on Bear Island, accessible from Maryland, offers scenic views of the Great Falls, as do vantage points on Olmsted Island (also accessible from Maryland). There are overlook points on the Virginia side. The Great Falls area is popular for outdoor activities such as kayaking, whitewater rafting, rock climbing, and hiking. Great Falls and Little Falls (about 5 miles downstream) are named in contradistinction to one another.

Great Falls Park is a small National Park Service (NPS) site in Virginia, United States. Situated on 800 acres (3.2 km2) along the banks of the Potomac River in northern Fairfax County, the park is a disconnected but integral part of the George Washington Memorial Parkway. The Great Falls of the Potomac River are near the northern boundary of the park, as are the remains of the Patowmack Canal, the first canal in the United States that used locks to raise and lower boats.

Carderock Recreation Area is a 100-acre park in Carderock, Maryland, part of the Chesapeake and Ohio Canal National Historical Park. The area is well known as a destination for its outdoor activities of rock climbing, hiking and biking. It is bounded by the Potomac River on the south and the Chesapeake and Ohio Canal on the north, and it is accessed from Clara Barton Parkway from the same exit as Carderock Division of the Naval Surface Warfare Center. The Recreation Area includes a picnic shelter, section C of the Billy Goat Trail, convenient access to the Chesapeake and Ohio Canal, and popular rock cliffs. The area has a long history of climbing and is notable for being the closest significant climbing area to Washington, D.C. As such, it is one of the most climbed cliffs in the eastern United States. There is no fee to enter the park.

Towlston Grange is an 18th-century plantation in Great Falls in Fairfax County, Virginia, United States. The estate served as a residence for several prominent members of the Fairfax family. Towlston Grange is located at 1213 Towlston Road in Great Falls. There is a photograph of Bryan Fairfax's Towlston Grange in its unrestored state, taken by "The Rambler" of the Washington, D.C. Evening Star newspaper in 1918, that shows a 1+1⁄2-story clapboarded house built in the English tradition.[4]

Matildaville is a ghost town located along the Patowmack Canal near present day Great Falls, Virginia, United States. It was named for the wife of Light Horse Harry Lee, on 40 acres of land owned at the time by Bryan Fairfax, 8th Lord Fairfax of Cameron, and served as headquarters for the Patowmack Company from 1785 until 1799. Now, all that remains of the town are a series of ruins on the grounds of Great Falls Park.

The Kemper Open was a golf tournament on the PGA Tour from 1968 to 2006. Perhaps more so than any other "regular" PGA Tour stop, the event wandered about, not just from course to course within a given metropolitan area, but along the East Coast. Originally sponsored by the Kemper Corporation, the inaugural event was played in 1968 at Pleasant Valley Country Club in Sutton, Massachusetts, before moving to the Quail Hollow Club in Charlotte, North Carolina the following year, where it stayed through 1979. (The Wells Fargo Championship is now held in Charlotte.) The event moved in 1980 to Congressional Country Club in Bethesda, Maryland, a suburb northwest of Washington, D.C., and to TPC at Avenel in 1987 in neighboring Potomac. Kemper Insurance dropped out as sponsor after the 2002 edition and was replaced by Friedman Billings Ramsey, which renamed the event the FBR Capital Open for a single year in 2003. Booz Allen Hamilton became the main sponsor in 2004, with the tournament being titled the Booz Allen Classic. The event returned to Congressional for a year in 2005 to accommodate renovations at Avenel. The purse in 2006 was $5.0 million, with $900,000 going to the winner; due to rain delays it concluded on Tuesday without a gallery. In 1992, Washington Redskins quarterback Mark Rypien, the reigning Super Bowl MVP, was given a sponsor's exemption into the tournament, but shot rounds of 80 and 91 and missed the cut by 28 strokes. As the Kemper Open, it was often played two or three weeks prior to the U.S. Open, making it a prime tune-up event; later it was either the week prior or after and many top players skipped it.. For 2007, the PGA Tour announced that it would reschedule the event for the fall, and Booz Allen declined to renew its sponsorship. The fall date was in turn canceled to make way for the new AT&T National, to take place at the same time as the Classic had. Also in 2006, the tournament ended on Tuesday due to persistent storms in the D.C. area. The conclusion of what turned out to be the final Booz Allen Classic was not televised. A new format (invitation only), new host for the tournament (Tiger Woods), and a return to Congressional Country Club marked the July 2007 stop in Washington for the FedEx Cup, the AT&T National. For record-keeping purposes, it is not a "successor" tournament officially, even though it is the "new" tour stop in the same region. During the 1970s, the Kemper Open was among the highest purses on tour, exceeding the majors.
