Relief Map: Cumberland Plateau, West Virginia and "Ridge and Valley" region of Virginia

On the southeastern portion of this map is the folded Appalachians of Virginia, also known as the Ridge-and-valley Appalachians, which are the roots of true ancient mountains, uplifted once again, with the harder rock layers forming ridges and the more erodable rocks becoming valleys.

A major fault line runs from southwest to northeast dividing the folded mountains from the Cumberland Plateau of West Virginia, a dissected plateau that forms the majority of the image. This area of sedimentary rock (including many coal) veins is, geologically speaking, not true mountains, but merely was uplifted and eroded. Note that the area is actually more rugged than the folded mountains, though not as high.
