Abstract This set of three outcrops is located south of the city of Knoxville, on the east side of Alcoa Highway (U.S. 129) one mi (1.6 km) south of the James E. Karnes Bridge over the Tennessee River (Fort Loudon Lake). The northernmost of the three outcrops is directly across Alcoa Highway from the Naval Reserve Station. The locality is in the southern part of the Knoxville 7½-minute Quadrangle (Fig. 1). The site is easily accessible, although Alcoa Highway is heavily traveled, and you are cautioned to cross the highway with great care. Parking is available on the east side of the highway just south of the Naval Reserve Station.
