I can't find anything about it specifically, but it seems very similar to Stone Mountain which is a good 70 or 80 miles to the east. There's a lot written about Stone Mountain:
"Stone Mountain is a pluton, a type of igneous intrusion. Primarily composed of quartz monzonite, the dome of Stone Mountain was formed during the formation of the Blue Ridge Mountains, part of the Appalachian Mountains. [2] It formed as a result of the upwelling of magma from within the Earth's crust. This magma solidified to form granite within the crust five to ten miles below the surface."
Whatever it is, it is pretty cool.
