Dennison spent his career studying the Appalachians, teaching and mentoring his students and professional colleagues, publishing papers, leading field trips, and presenting ideas at regional, national and international conferences. This volume is a collection of papers contributed by former students and colleagues to honor his memory. Learn about and paleontology ranging in age from to in Kentucky, , Tennessee, Virginia, and West Virginia; airfall tephras throughout the eastern ; a Devonian lonestone; a Middle bentonite in North Carolina and its relationship to a volcanic swarm in western Virginia; and a 3D model of a ductile duplex in northwestern Georgia. The stratigraphic and geologic diversity of the papers reflects Dennison’s many interests and relationships with a large of geoscientists”— Provided by publisher.
