This article will examine the origins and geology of the Stone Mountain Monolith in North Georgia, the history of the area, and the people and groups who used the site for social and commercial purposes. Stone Mountain is an igneous intrusion often referred to as a geologic pluton. The granitic pluton is part of the Piedmont Plateau region of the Appalachian Mountains and formed along the same geologic fault line that created the Blue Ridge Mountains but is not part of the Blue Ridge Range. Northern and eastern Georgia have relatively frequent seismic activity with ten earthquakes recorded in 2013. These earthquakes occurred at an average depth of 9.6 km, making them less noticeable and causing less property damage. This same seismic activity created Stone Mountain 300 million years ago during the final stages of the Alleghenian orogeny, when massive shifting of tectonic plates allowed a large mass of magma from beneath the Earth's crust to rise. Signs of flow structure on the mountain show that the stone formed underground after several eruptive pulses failed to break through and then cooled to form, ultimately creating a mass of granite that rises 825 feet above the ground, it extends 9 miles underground and has a circumference of 5 miles at its top. base, making it the largest exposed dome in the world. The top of the dome, which rises 1,683 feet above sea level, is bare stone with rock pools and an unobstructed view that extends to Kennesaw Mountain, Amicacola Falls and Mt. Yonah state parks, including an overlook breathtaking view of the Atlanta skyline. contrast with the surrounding flat and rolling landscape which creates a geomorphic monadnock.
