WHAT MOUntain range extends into alabama?

The Appalachian Mountains (French: les Appalaches) are a vast system of North American mountains, partly in Canada, but mostly in the United States, forming a zone, from 100 to 300 miles wide, running from the island of Newfoundland some 1,500 miles south-westward to central Alabama in the United States (with foothills in northeastern Mississippi), although the northernmost mainland portion ends at the Gaspé Peninsula of Quebec. The system is divided into a series of ranges, with the individual mountains averaging around 3,000 ft (900 m). The highest of the group is Mt. Mitchell in North Carolina (6,684 ft or 2,037m), which is the highest point in the United States east of the Mississippi River as well as the highest point in eastern North America.
