I would have thought that the Appalachian Mountains would have more than the relatively flat areas of those 2 cities, especially since they are so old. The area of San Diego I live in now has very old fault lines and you can see them just driving to the local stores since there are certain roads that are so hilly and steep while the surrounding areas are flat.
