Formed approximately 500 million years ago by accretion along the Gondwanan tectonic plate, they are thought to have once peaked at some 20,000 feet,[2] before eroding to a maximum of just over 1,100Â ft. The range's high point is High Rock Mountain (1,188 feet/362 meters as measured by the NC Geodetic Survey), in southwestern Davidson County.
