Spruce Mountain, located in eastern West Virginia, is the highest ridge of the Allegheny Mountains. The whale-backed ridge extends for only 16 miles (26 km) from northeast to southwest, but several of its peaks exceed 4,500 feet (1,400 m) in elevation. The summit, Spruce Knob (4863 ft; 1482 m), is the highest Allegheny Mountain point both in the state and the entire range, which spans four states.
