 Shelving Rock is located along TN-143 just outside Roan Mountain State Park.In 1826, Josh, Ben, and Jake Perkins — three brothers from Crab Orchard, Tennessee — were searching for ginseng on the North Carolina side of Roan (possibly evading an arrest warrant in Tennessee) when they noted deposits of iron ore near Cranberry Creek.This led to the discovery of a massive iron ore deposit known as the Cranberry vein and the establishment of the Cranberry Mine, which extracted the ore for nearly a century until being forced to close by the Great Depression.
