ABSTRACT This field guide describes three accessible sites along the Dandridge-Vonore fault zone in the Eastern Tennessee seismic zone. These sites reveal bedrock faulted against Quaternary river sediments, including (1) a thrust fault on the Little River near Alcoa, Tennessee; (2) a series of thrust faults exposed in a drainage ditch that thrust Conasauga Shale against Quaternary colluvium in the footwall; and (3) a normal fault at Tellico Lake near Vonore, Tennessee, with Quaternary sediments faulted against Conasauga Shale.
