The chain of appalachian mountains clash forms a barrier to travel east-west 480 million years ago as it forms a series of alternating edges and valleys that extend across from any road that extends from east to west. It is a wide mountain range that extends in the eastern parts of the North American continent parallel to the shores of the Atlantic Ocean. It has been subjected to carving operations since its formation.
