Allegheny Mountains

A mountain range comprising the western part of the Appalachian Mountains. The range extends about 805 km (500 mi) from northern Pennsylvania to southwest Virginia and rises to approximately 1,483 m (4,862 ft) in northeast West Virginia. The eastern Alleghenies, also called the Allegheny Front, form a steep escarpment and are more rugged than the western portion, known as the Allegheny Plateau, which extends into Ohio and Kentucky.
