Stone Mountain is a quartz monzonite dome monadnock and the site of Stone Mountain Park in Stone Mountain, Georgia. At its summit, the elevation is 1,686 feet (514 m) MSL and 825 feet (251 m) above the surrounding area. Stone Mountain is well-known not only for its geology, but also for the enormous rock relief on its north face, the largest bas-relief in the world. The carving depicts three Confederate figures during the Civil War: Stonewall Jackson, Robert E. Lee, and Jefferson Davis.

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 around 300–350 million years ago (during the Carboniferous period), part of the Appalachian Mountains. 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. Stone Mountain pluton continues underground 9 miles (14 km) at its longest point into Gwinnett County.

The top of the mountain is a landscape of bare rock and rock pools, and it provides views of the surrounding area including the skyline of downtown Atlanta, often Kennesaw Mountain, and on very clear days even the Appalachian Mountains.

The clear freshwater pools of the summit form by rainwater gathering in eroded depressions, and are home to unusual clam shrimp and fairy shrimp. The tiny shrimp appear only during the rainy season. Through the process of cryptobiosis, the tiny shrimp eggs (or cysts) can remain dormant for years in the dried out depressions, awaiting favorable conditions.
