Wind gap

From Wikipedia, the free encyclopedia

A wind gap is a mountain pass through which a stream, now abandoned as a result of stream piracy, once flowed[1]. A water gap is a similar feature, but one in which a waterway still flows. Water gaps and wind gaps often offer a practical route for roads and railroads to cross a mountain ridge.

Examples of wind gaps in the Blue Ridge Mountains of Virginia include Swift Run Gap, Rockfish Gap, and Buford's Gap. The latter 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.
