"Spanning a vast area from Virginia to Georgia, the Southern Appalachians are some of the oldest mountains on Earth. Molded and shaped over eons by volcanism, erosion, glaciation, and other geologic forces, these mountains are known worldwide for their unusual beauty and rich biological diversity. The geological events that shaped this region influenced the landscape, climate, soils, and living things that we see today. An increased understanding of the Earth and its geologic history enhances our appreciation of the world around us and allows us to act in harmony with natural processes."--Container.
