Plate T-12: Folded Appalachians

Abstract:: The mental picture of the Appalachian Mountains most of us have is that of long linear ridges and valleys that form a belt some 25 to 100 km wide through Pennsylvania/Virginia/West Virginia and the Carolinas. With relief of 300 to 1000 m or more, these ridges stand out as distinct mountains. This page describes the general geomorphology and geology of the Appalachian Mountains with the use of text and remotely sensed imagery. It is part of 'Geomorphology from Space', an out-of-print NASA publication on the use of remote sensing to study landforms. A link to the rest of the publication is provided.
