The Alleghanian orogeny, which occurred during the late Carboniferous period, is believed to have formed the largest mountain range in the Appalachian system. This orogeny resulted from the collision between North America and Africa, which created the supercontinent of Pangaea. The resulting mountain range stretched from Newfoundland to Alabama and was over 5000 km long.
