Clarke's Gap, also known as Clarks Gap, is a pass through Catoctin Mountain west of Leesburg, Virginia. The gap has an elevation of 643 feet (196 m). The gap is not a true wind gap, but rather a man-made railroad cut through a local saddle point between two ridges to the southeast and northwest created by the drainage of Dry Mill Branch of Tuscarora Creek to the east and an unnamed tributary of Catoctin Creek to the west. The original road between Alexandria and Winchester, known as Vestal's Gap or Braddock's Road passed through the gap beginning in the middle 18th century. Later, in the 1860s the Alexandria, Loudoun and Hampshire Railroad, predecessor of the Washington and Old Dominion Railroad was routed through the gap. The railroad christened the gap when it established a station there, naming it after a nearby landowner, Addison H. Clarke. Today, Dry Mill Road (Virginia State Route 699 (VA Route 699)) and the Washington and Old Dominion Trail still pass through the gap. VA Route 7 and VA Route 9 pass just to the north of the gap, through a man-made highway cut, which the Virginia Department of Transportation has mistakenly signed as "Clarks Gap".

Fort Johnston, also known as Fort Geary, is a Civil War era earthen fort atop a 670 feet (200 m) peak of Catoctin Mountain just west of Leesburg, Virginia. Constructed in the winter of 1861-62 following the Battle of Balls Bluff, it is one of three forts constructed to defend the town from the threat of possible invasion. The fort was built in the design of a four-point star with arm of each point measuring roughly 110 feet (34 m) in length. The fort was only sporadically occupied by Confederates, as the main threat of invasion came from the east across the Potomac. In 1862, when Loudoun County was invaded by the Union army, the fort was abandoned and later occupied by the Federals who rechristened it Fort Geary in honor of their commander. Throughout the war, Leesburg was rarely held in force by either side of the conflict and the fort saw little use. Today, parts of the earthworks of the fort still exist, and are located on private property on Fort Johnston Road.

Catoctin County is the name of a proposed new county in Northern Virginia that would be formed from the western portions of Loudoun County. The movement to form the new county began in 2005 with a letter to The Washington Post.Under the proposal, the area of Loudoun County west of the Catoctin Mountain watershed, known as the Loudoun Valley would be separated from the portion of the county east of that watershed. The eastern portion of Loudoun would retain its name and county government. Purcellville would become the seat of the new county's government. Its name is derived from the Catoctin Mountain whose watershed would make its eastern border and Catoctin Creek which flows through its proposed boundary.The idea of Catoctin County began as a movement to combat the rapid development of the historically rural western region of Loudoun County, one of the fastest-growing counties in the United States in the 1990s. In general though, the heaviest development has been to the east of Catoctin Mountain in eastern Loudoun. Support for the movement waned, though it resurfaced in 2012 with the proposed extension of the Metro Silver Line, resulting in increased taxation on Loudoun residents.
