Excerpt from Geomorphology of the Central Appalachians The number, origin, age, and correlation of peneplains Within the area traversed present a problem concerning Which there is still much difference of opinion. Although a larger number of erosion levels may be represented, the evolution and topography of the Appalachian region will be described With reference to the five most prominent peneplains and to altitudes above and below them. These peneplains, named in the order Of their age, are the pre-triassic, the Fall Zone (jura-cretaceous), the Schooley (tertiary), the Harrisburg (probably late Tertiary), and the Somerville (possibly Pleistocene). The authors hope that this guidebook Will be regarded, not as a statement of facts to be accepted Without question, but merely as a guide to field dis eussions of problems encountered on the journey.

Excerpt from Geology and Geomorphology of the Southern Central Blue Ridge: An Indexed Bibliography Much research has already been done on the geology and geomorphology of the Blue Ridge. The purpose of this bibliography is to provide researchers access to these accumulated references. The emphasis of the bibliography is on the geology of the region, for there appears to be relatively little scientific literature written on the geomorphology of this portion of the Blue Ridge. This bibliography covers the Central and Southern Blue Ridge physiographic provinces from southcentral Pennsylvania to northeastern Georgia. Along this corridor the Blue Ridge ranges from five miles to more than 50 miles in width (hunt However, the geologic processes which generated the Blue Ridge were also responsible for the stratigraphy and structure of the rocks in the remainder of the Appalachian belt, namely the Piedmont, Valley and Ridge, and the Appalachian Plateaus. Although the Blue Ridge terminates in Georgia, the rocks, stratigraphy, and structural trends continue into Alabama and in fact may be continuous with the Ouachita Province farther to the west. Because of the intimate geologic relationship of the Appalachian physiographic provinces, the author has included selected references on Piedmont and Valley and Ridge geology representative of this relationship (thomas et al. 1980; Thomas 1973; Milici 1970, The earliest works in geology appeared to have two functions: to describe the geology of an area (kieth 1903, 1904, 19058; Hitchcock 1885; Jones 1923; etc.) or to determine the economic importance of mineral deposits (emmons and Laney 1926.

In 1889 William Morris Davis offered in his paper The Rivers and Valleys of Pennsylvania'' an elegant set of arguments for the origin of the ridges and gaps, and went on to propose a model for the drainage development and geomorphic evolution of the Appalachians. His work served to focus the geomorphic community into an intense, extended debate on the nature and fundamental controls of the long-term erosion of the Appalachians. The 100th anniversary of Davis' provocative paper prompted the convening of a symposium to address some of the fundamental questions about the Appalachians, the 1989 Geomorphology Symposium. The theme of this symposium was the geomorphic evolution of the Appalachians. This volume brings together a collection of papers from the symposium, to provide a summary of the current state of knowledge.
