The Rankin Rock Wall

The rock wall includes 107 rock specimens documenting the geologic history of the Appalachian region, including examples of igneous, sedimentary, and metamorphic rocks as well as diverse geologic structures. The specimens are framed by "Elk Stone," part of the Cranberry Gneiss, one of the oldest rocks in North Carolina. The wall is on the ground floor of Rankin Science West, just outside the main office of the Department of Geology.
