Clarke's Gap
Clarke's Gap, also known as Clarks Gap, is a pass through Catoctin Mountain west of Leesburg, Virginia. The gap has an elevation of . 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 ...

Saddle Point
In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function. An example of a saddle point is when there is a critical point with a relative minimum along one axial direction (between peaks) and at a relative maximum along the crossing axis. However, a saddle point need not be in this form. For example, the function f(x,y) = x^2 + y^3 has a critical point at (0, 0) that is a saddle point since it is neither a relative maximum nor relative minimum, but it does not have a relative maximum or relative minimum in the y-direction. The name derives from the fact that the prototypical example in two dimensions is a surface that ''curves up'' in one direction, and ''curves down'' in a different direction, resembling a riding saddle or a mountain pass between two peaks forming a landform saddle.

Washington And Old Dominion Railroad
The Washington and Old Dominion Railroad (colloquially referred to as the W&OD) was an intrastate short-line railroad located in Northern Virginia, United States. The railroad was a successor to the bankrupt Washington and Old Dominion Railway and to several earlier railroads, the first of which began operating in 1859. The railroad closed in 1968. The Railroad's oldest line extended from Alexandria on the Potomac River northwest to Bluemont at the base of the Blue Ridge Mountains near Snickers Gap, not far from the boundary line between Virginia and West Virginia. The railroad's route largely paralleled the routes of the Potomac River and the present Virginia State Route 7. The single-tracked line followed the winding course of Four Mile Run upstream from Alexandria through Arlington to Falls Church. At that point, the railroad was above the Fall Line and was able to follow a more direct northwesterly course in Virginia through Dunn Loring, Vienna, Sunset Hills (now in Rest ...

Wind Gap (topography)
A wind gap (or air gap) is a gap through which a waterway once flowed that is now dry as a result of stream capture. A water gap is a similar feature, but one in which a waterway still flows. Water gaps and wind gaps often provide routes which, due to their gently inclined profile, are suitable for trails, roads, and railroads through mountainous terrain. Examples of wind gaps in the Blue Ridge Mountains of Virginia include Swift Run Gap, Rockfish Gap, and Buford's Gap. The last was the original crossing of the Blue Ridge Mountains near Bedford for the Virginia and Tennessee Railroad, later the Norfolk and Western Railway, a precursor of today's Norfolk Southern Railway system. Another wind gap with substantial importance in U.S. history is the Cumberland Gap near the junction of Kentucky, Virginia, and Tennessee.
