Are the application mountains located

I am almost 100% sure there is no such thing. However, the APPALACHIAN Mountains are located near the Eastern coast of the United States, stretching along most of it, atleast, they are smaller and less jagged than the Rocky mountains (West coast of U.S. and Canada), because the Appalachians have been exposed to more erosion, because they are older. The Rockys are newer, bigger, and jaggeder.

There you go!
