Valley of East Tennessee bear Jonesboro, looking southeast. This valley is composed of many rounded hills, characteristic of Knox dolomite, with red clay soil and some chert. The summits rise in general to elevations of 1,700 to 1,800 feet and are remnants of an ancient plain that extends to the foot Cherokee Mountain, in the background. This mountain rises abruptly about 1,000 feet above the limestone hills. Beyond, a peak of Buffalo Mountain and the high dome of Unaka Mountain are visible. Washington County, Tennessee. 1907. Figure 16 in U.S. Geological Survey. Folio 151. 1907.
