Through the process of cryptobiosis, the tiny shrimp eggs (or cysts) can remain dormant for years in the dried out depressions, awaiting favorable conditions. The rare Georgia oak was first discovered at the summit, and several specimens can easily be found along the walk-up trail and in the woods around the base of the mountain.
In the fall, the extremely rare Confederate yellow daisy (Helianthus porteri) flowers appear on the mountain, growing in rock crevices and in the large wooded areas.
The largest bas-relief sculpture in the world, the Confederate Memorial Carving depicts three Confederate leaders of the Civil War: President Jefferson Davis and Generals Robert E. "Stonewall" Jackson (and their favorite horses, "Blackjack", "Traveller", and "Little Sorrel", respectively).
The entire carved surface measures 1.57 acres (6,400 m).
Over time, erosion eventually exposed the present mountain of more resistant igneous rock.
This intrusion of granite also gave rise to Panola Mountain and Arabia Mountain, both in De Kalb County, smaller outcroppings farther south of Stone Mountain.
Numerous reference books and Georgia literature have dubbed Stone Mountain as “the largest exposed piece of granite in the world".
This misconception is most likely a result of misrepresentation by granite companies and early park administration.
The granite intruded into the metamorphic rocks of the Piedmont region during the last stages of the Alleghenian Orogeny, which was the time when North America and North Africa collided.
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.
On some days, the top of the mountain is shrouded in a heavy fog, and visibility may be limited to only a few feet.
Stone Mountain is a quartz monzonite dome monadnock and the site of Stone Mountain Park near Stone Mountain, Georgia.
At its summit, the elevation is 1,686 feet (514 m) MSL and 825 feet (251 m) above the surrounding area.
