Stone Mountain is the granite dome monadnock located in Stone Mountain, Georgia, a suburb of Atlanta. At its summit, the elevation is 1,683 feet (513 m) amsl and 825 feet (251.5 m) above the surrounding plateau. The mountain extends underground to several surrounding counties. Stone Mountain is claimed by some to be the largest exposed granite 'stone' in the world.[1]. By comparison, however, it is only about one fourth the height of El Capitan in Yosemite (3,000 feet above valley level), the tallest known exposed granite monolith on earth. [2]. Stone Mountain is well-known not only for its geology, but also for the enormous bas-relief on its north face, the largest bas-relief in the world.[1] Three figures of the Confederate States of America are carved there: Stonewall Jackson, Robert E. Lee, and Jefferson Davis.
