The Appalachian Mountains extend from central Alabama around 1,500 miles north to Canada. Mt. Mitchell, located in North Carolina and rising 6,684 feet, is the highest point in the Appalachians.
A series of ranges make up the Appalachians, with the most significant being the Cumberland Mountains in Tennessee, Blue Ridge Mountains in Virginia, the Catskills in New York, the Alleghenies in Pennsylvania, the White Mountains in New Hampshire and the Green Mountains in Vermont.
According to geologists, the Appalachians were formed more than 470 million years ago. The Appalachians are among the oldest mountains on the planet, and it is thought that at one time, they were as tall as the Himalayas of today. Wearing away of the mountains has left them much shorter today than they were when they originally formed.
