The Appalachian Mountain Range is the largest and longest in the eastern part of North America. This mountains range is also one of the oldest in the world. Because of its size and geology, the Appalachians are divided into multiple mountain ranges, including the Alleghenies, Catskills, Green Mountains, White Mountains, and many more.

The Alleghenies occupy territory from western Pennsylvania to eastern West Virginia, the Catskills in New York, the White Mountains in New Hampshire and Maine, and the Green Mountains in Vermont.

The Adirondacks are often considered as part of the Appalachians, but they are actually belonging to a totally different orogenesis and are not connected geologically.
