Abstract The Appalachian Highlands consist of the Piedmont, Blue Ridge, Valley and Ridge, and Appalachian Plateau physiographic provinces (Fenneman, 1938) (Fig. 1). The Interior Low Plateau province is also included with this discussion of the Appalachian Highlands. The Quaternary geology of the unglaciated Appalachians is challenging because of the complexity of its montane landscapes and limited datable deposits. Surficial deposits in the Appalachians are difficult to date by radiocarbon because of relatively low sedimentation rates that, together with a high oxidation rate, result in poor preservation of organic material except below the water table. Only a handful of numerical dates older than late Wisconsin exist from deposits of alluvium and colluvium. Moreover, alluvial terraces, as well as colluvial deposits, are generally discontinuous in distribution, poorly exposed, and have considerable soil and vegetation cover, hindering reliable stratigraphic and morphologic correlation. Beyond the range of radiocarbon dating, correlation is even more tentative owing to postdepositional erosion and dissection of geomorphic surfaces, and to the lack of numerical-age-dating techniques applicable to these surficial deposits. Tephra are unknown. Knowledge of late Quaternary climatic changes in the Appalachian region, from palynological study and radiocarbon dating of lacustrine and peat deposits, is relatively more advanced than stratigraphie investigations. Sinkholes formed in carbonate terrains provide continuous paleoenvironmental and paleovegetation records extending back through middle Wisconsin time. This paleoecological knowledge provides a tentative framework for interpreting landscape development during the Quaternary. However, well-dated palynological sequences from lacustrine sites commonly cannot be correlated directly with nonlacustrine

Abstract During the first several decades of the twentieth century, there was much interest in the geomorphology of the Appalachians. When con-cern with erosion cycles and long-term drainage evoldtion gave way to concern with processes and mechanics in the late 1940s, however, geomorphic research in the Appalachians dropped off precipitously. With the notable exception of John Hack, relatively little work in this area was carried out in the 1950s and 1960s. In the past decade, however, interest in the geomorphology of the Appalachian region has revived considerably. This annotated bibliography of 1,200 items is published in the hopes that it will both stimulate interest as well as facilitate research in the region. The area covered most thoroughly by the bibliography is the unglaciated Appalachian Highlands (i.e., the Piedmont, Blue Ridge, Valley and Ridge, and Appalachian Plateau provinces). Some articles from the northern Appalachians are included, but not those concerned primarily with glaciation.The Interior Low Plateau and the Ozark Plateaus are also covered, but in a less thorough manner. Papers from the Coastal Plain province that appear to bear on the geomorphology of the adjacent Piedmont province are included. For the most part, only papers that I was able to obtain to read, or at least inspect, are included. Only selected published abstracts are included, with emphasis on those abstracts for which no paper by the same author(s) dealing with the same subject has been published. In selecting papers for the bibliography, the criteria for appropriate papers were difficult to decide upon

Abstract William Morris Davis (1888) considered the Appalachians to have had an important role in the development of geomorphology. He saw the systematic study of topography as largely of American origin, and suggested that there were two steps in its development. The first began about 1840 with the founding of the Eastern state surveys, during which geologists such as Lesley (1856) established the intimate relationship between topography and structure (in the broad sense) in the Appalachians. During this first step, according to Davis, topographic form was regarded as a completed product of extinct processes. Topography revealed structure, but it did not then reveal the long history that the structure has passed through. … The systematic relation of forms to structure, base level, and time; the change of drainage areas by contest of headwaters at divides; the revival of exhausted rivers by massive elevations of their drainage areas; all these consequences of slow adjustments were then unperceived (Davis, 1888, p. 14). The awareness of such principles, the second step in the advancement of the study of topography, came about largely as a result of the geological exploration of the western U.S., exemplified by the work of Powell (1875, 1876) and Gilbert (1877). Once this awareness came about, however, these principles were applied to the Appalachians; Davis (1888, p. 15) stressed the importance of the Appalachians in this second phase as well as the first: If it be true that the greater part of this second advance is American like the
