Topographic gap made by a former waterway
A
wind gap
(or
air gap
)
[1]
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.
