The Appalachian Mountains (French: les Appalaches) are a large group of North American mountains. They are partly in Canada, but mostly in the United States. They form an area from 100 to 300 miles wide, running 1,500 miles from the island of Newfoundland in Canada to central Alabama in the United States. The individual mountains average around 3,000 ft (900 m) in height. The highest is Mt. Mitchell in North Carolina (6,684 ft or 2,037m). Mt. Mitchell is also the highest point in the United States east of the Mississippi River as well as the highest point in eastern North America.
The term Appalachia is used to refer to regions associated with the mountain range. It refers to the mountain range and the hills and plateau region around it. The term is often used to refer to just areas in the central and southern Appalachian Mountains. These areas usually include parts of the states of Kentucky, Tennessee, Virginia, West Virginia, and North Carolina, and sometimes extending as far south as northern Georgia and western South Carolina, as far north as Pennsylvania, and as far west as southeastern Ohio.
