Allegheny Mountains, mountainous eastern part of the Allegheny Plateau in the Appalachian Mountains, U.S. The Allegheny range extends south-southwestward for more than 500 miles (800 km) from north-central Pennsylvania to southwestern Virginia. Rising to Mount Davis (3,213 feet [979 metres]; highest point in Pennsylvania) and Spruce Knob (4,863 feet [1,482 metres]; highest point in West Virginia), the mountains consist of nearly parallel northeast–southwest ridges that are drained through the gorges cut by the North Branch of the Potomac and the New rivers. Parts of the Monongahela, George Washington, and Jefferson national forests encompass the mountains, which are noted for their scenic beauty. Once forming a barrier to western communication, they are now crossed by many railroads and highways. The name Alleghenies is also used in reference to the Allegheny Plateau.
