Stone Mountain is a quartz monzonite dome monadnock in Stone Mountain, Georgia. At its summit, the elevation is 1,686 feet (513 m) amsl and 825 feet (251.5 m) above the surrounding area. Stone Mountain granite extends underground 9 miles (14 km) at its longest point into Gwinnett County. Numerous reference books and Georgia literature have dubbed Stone Mountain as “the largest exposed piece of granite in the world". This misnomer is most likely a result of advertisement by granite companies and early park administration. In actuality, there are larger exposed granite landscapes throughout the world including the Sierra Nevada mountain range in California. Stone Mountain, though often called a pink granite dome, is actually a quartz monzonite rock when described in geologic terms and is therefore not technically granite. 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. Three figures of the Confederate States of America are carved there: Stonewall Jackson, Robert E. Lee, and Jefferson Davis.
The mountain is more than five miles (8 km) in circumference at its base. The summit of the mountain can be reached by a steep walk-up trail, which starts near the Confederate Hall and West gate entrance. Alternatively, the summit is reachable by the Skyride.
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 maybe limited to only a few feet. 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, and it is believed that the adult shrimp die when the pools dry up, leaving behind eggs to survive until the next rains.
The mountain's lower slopes are wooded. 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.
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. 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.
The "granite" is composed of quartz, feldspar, microcline and muscovite, with smaller amounts of biotite and tourmaline. Embedded in the "granite" are xenoliths or pieces of foreign rocks entrained in the magma.
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. Over time, erosion eventually exposed the present mountain of more resistant igneous rock, in processes similar to those that have exposed Devils Tower National Monument in Wyoming.
The mountain's composition was described by one political commentator—and used as such as a simile for racial segregation in the 1950s—as "soft, exfoliating rock [which] turns to dust under the hammer."
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. Lee and Thomas J. "Stonewall" Jackson (and their favorite horses, "Blackjack", "Traveller", and "Little Sorrel", respectively). The entire carved surface measures 3 acres (12,000 m2), about the size of three football fields. The carving of the three men towers 400 feet (120 m) above the ground, measures 90 by 190 feet (58 m), and is recessed 42 feet (13 m) into the mountain. The deepest point of the carving is at Lee's elbow, which is 12 feet (3.7 m) to the mountain's surface.
In 1912, the carving existed only in the imagination of Mrs. C. Helen Plane, charter member of the United Daughters of the Confederacy (UDC). The Venable family, owners of the mountain, deeded the north face of the mountain to the UDC in 1916. The UDC was given 12 years to complete a sizable Civil War monument. Gutzon Borglum was commissioned to do the carving, and he with the Stone Mountain project.
In 1958, at the urging of Governor Marvin Griffin, the Georgia legislature approved a measure to purchase Stone Mountain for $1,125,000. In 1963, Walker Hancock was selected to complete the carving, and work began in 1964. The carving was completed by Roy Faulkner, who later operated a museum (now closed) on nearby Memorial Drive commemorating the carving's history. The carving was considered complete on March 3, 1972.
Stone Mountain is where the second KKK was formed in 1915. It has also been used as a site for Klan rallies throughout the years.
On many summer nights the mountain is home to the Laser show Spectacular which uses popular and classic music to entertain park guests with a large fireworks and laser light display. The American Civil War is acknowledged, but the strength of a reunited country concludes the message, with Sandi Patti singing the Star Spangled Banner. There are still old favorites included with the show, “Devil Went down to Georgia”, “Celestial Soda Pop”, and “Trilogy”. There have been several additions to the show for its 25th anniversary.
Carving and the Ku Klux Klan
Ku Klux Klan activities at Stone Mountain are deep-rooted, although the original conception of the memorial pre-dates the 1915 revival of the Klan. The revival of the Ku Klux Klan was emboldened by the release of D. W. Griffith's Klan-glorifying film The Birth of a Nation, and by the lynching of Leo Frank, who was convicted in the murder of Mary Phagan. On November 25, 1915, a group of robed and hooded men met at Stone Mountain to create a new incarnation of the Klan. They were led by William J. Simmons, and they included a group calling itself the Knights of Mary Phagan. A cross was lit, and the oath was administered by Nathan Bedford Forrest II, the grandson of the original Imperial Grand Wizard, Gen. Nathan B. Forrest, and was witnessed by the owner of Stone Mountain, Samuel Venable.
Fundraising for the monument resumed in 1923, and in October of that year, Venable granted the Klan easement with perpetual right to hold celebrations as they desired. Because of their deep involvement with the early fund-raising and their increasing political clout in Georgia, the Klan, along with the United Daughters of the Confederacy, were able to influence the ideology of the carving, and they strongly supported an explicitly Confederate memorial. Of the $250,000 raised, part came directly from the Ku Klux Klan  but part came from the federal government, which in 1924 issued special fifty-cent coins with Robert E. Lee and Stonewall Jackson on them.
Dr. Martin Luther King, Jr. mentioned the monument in his 1963 "I Have a Dream" speech in Washington, D.C., when he said "let freedom ring from Stone Mountain of Georgia!" Ironically, granite suppliers in Georgia sent samples cut from Stone Mountain to the Martin Luther King, Jr. Memorial Foundation to be considered for use in a planned monument in King's honor; the Foundation later chose to use granite imported from China.
Aviation Accidents on Stone Mountain
According to George Weiblen's annotated calendar for Monday, May 7, 1928: "Mail plane crashed on mountain at 8:00 P.M."
Around dusk on September 16, 2003, a small airplane crashed into the back of the mountain, a remote cliff area which is not normally accessible. The pilot, the airplane's only occupant, was confirmed dead. Although the official accident report notes no probable cause, a witness stated that the pilot threatened on multiple occasions to commit suicide by flying into Stone Mountain. Firefighters took the Skyride up and then rappelled down to the site of the plane's wreckage.
Stone Mountain Park, which surrounds the Confederate memorial, is owned by the state of Georgia and managed by the Stone Mountain Memorial Association, a Georgia state authority. The Herschend Family Entertainment Corporation currently has a long-term contract to operate park attractions while the Stone Mountain Memorial Association retains ownership and the right to reject any project deemed unfit.
During the 1996 Summer Olympics, Stone Mountain Park provided venues for Olympic events in tennis, archery and track cycling. The venues for archery and cycling were temporary and are now part of the songbird and habitat trail.
