The Appalachian Mountains, often called the Appalachians, are a

system of mountains in eastern North America. The Appalachians

first formed roughly 480 million years ago during the Ordovician

Period. It once reached elevations similar to those of the Alps and

the Rocky Mountains before naturally occurring erosion. The

Appalachian chain is a barrier to east-west travel, as it forms a

series of alternating ridgelines and valleys oriented in opposition

to most roads running east or west. The system is divided into a

series of ranges, with the individual mountains averaging around

3,000 ft (910 m). The highest of the group is Mount Mitchell in

North Carolina at 6,684 feet (2,037 m).
