The Chattanooga 1°x2° quadrangle is the westernmost of four adjacent quadrangles that transect the southern Appalachians. It includes, from east to west, parts of five physiographic provinces or sections—Blue Ridge, Valley and Ridge, Cumberland Plateau, Highland Rim, and Nashville Basin. These provinces or sections reflect differences in the underlying bedrock. Includes two plates. By S.H.B. Clark, G.T. Spanski, D.G. Hadley, and A.H. Hofstra, 1993. 35 pages.
