The Appalachian Mountains run almost diagonally across the state, extending from New York through West Virginia and Virginia. Note within the Appalachian range are several separate areas called by other names such as the Allegheny Mountains, The Pocono Mountains, and The Blue Ridge Mountains (which extend into Virginia).
