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 was once owned by the Venable Brothers and was the site of the founding of the second Ku Klux Klan in 1915. It was purchased by the State of Georgia in 1958.
Stone Mountain is more than 5 miles (8 km) in circumference at its base. The summit of the mountain can be reached by a walk-up trail on the west side of the mountain or by the Skyride aerial tram.

Geology
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. 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. Stone Mountain, though often called a pink granite dome, actually ranges in composition from quartz monzonite to granite and granodiorite.
The minerals within the rock include quartz, plagioclase feldspar, microcline and muscovite, with smaller amounts of biotite and tourmaline. The tourmaline is mostly black in color, and the majority of it exists as optically continuous skeletal crystals, but much larger, euhedral pegmatitic tourmaline crystals can also be found in the mountain's numerous, cross-cutting felsic dikes. 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. This intrusion of granite also gave rise to Panola Mountain and Arabia Mountain, both in DeKalb County, smaller outcroppings further east of Stone Mountain.

Natural history
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. 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.
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.
Confederate Memorial
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 1.57 acres (6,400 m2). The carving of the three men towers 400 feet (120 m) above the ground, measures 76 by 158 feet (23 by 48 m), and is recessed 42 feet (13 m) into the mountain. The deepest point of the carving is at Lee's right elbow, which is 12 feet (3.7 m) to the mountain's surface.
The carving was conceived by Mrs. C. Helen Plane, a charter member of the United Daughters of the Confederacy (UDC). The Venable Brothers, 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. Borglum abandoned the project in 1925 (and later went on to begin Mount Rushmore). American sculptor Augustus Lukeman continued until 1928, when further work stopped for thirty years. 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.
Carving and the Ku Klux 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 coincided with the August 1915 lynching of Leo Frank. On November 25 of the same year, a small group, including fifteen robed and hooded "charter members" of the new organization, met at Stone Mountain to create a new iteration of the Klan. They were led by William J. Simmons, and included two elderly members of the original Klan. As part of their ceremony, they burned a crude cross.
Fundraising for the monument resumed in 1923. In October of that year, Venable granted the Klan easement with perpetual right to hold celebrations as they desired. The influence of the UDC continued, in support of Mrs. Plane's vision of a carving explicitly for the purpose of creating a Confederate memorial. The UDC established the Stone Mountain Confederate Memorial Association (SMCMA) for fundraising and on-site supervision of the project. Venable and Gutzon Borglum, who were both closely associated with the Klan, arranged to pack the SMCMA with Klan members. The SMCMA, along with the United Daughters of the Confederacy continued fundraising efforts. Of the $250,000 raised, part came from the federal government, which in 1925 issued special fifty-cent coins with the soldiers Robert E. Lee and Stonewall Jackson on them, but would not allow the politician Jefferson Davis to be included. When the state completed the purchase in 1960, it condemned the property to remove Venable's agreement to allow the Klan perpetual right to hold meetings on the premises.
Confederate Memorial controversy
After the Charleston church shooting in the summer of 2015, Stone Mountain was the subject of a political debate related to the removal of symbols of the Confederacy. This controversy was stimulated by a movement in other states to remove the Confederate battle flag from public areas.
A proposal was made to remove the Confederate carving from Stone Mountain Park. However, according to Georgia state law, no one is allowed to alter the figures carved upon the stone face. Any changes within the state park would require approval by the state legislature. Removal would be seen as destruction of art history, due to the beginning of the carving by Gutzon Borglum, who later went on to begin Mount Rushmore.
On October 11, 2015, The Atlanta Journal-Constitution reported the park is considering a proposal of a permanent "Freedom Bell" honoring Martin Luther King, Jr. and the line "Let freedom ring from Stone Mountain of Georgia" as part of King's "I Have A Dream" speech of 1963. The proposed monument is inspired by a bell-ringing ceremony held in 2013 honoring the 50th anniversary of King's speech.
History
Human habitation of Stone Mountain and its surroundings date back into prehistory. When the mountain was first encountered by European explorers, its summit was encircled by a rock wall, similar to that still to be found on Georgia's Fort Mountain. The wall is believed to have been built by early Native American inhabitants of the area, although its purpose remains unclear. By the beginning of the 20th century the wall had disappeared, the rocks having been taken away by early visitors as souvenirs, rolled down the rockface, or removed by the commercial quarrying operation. The mountain was as well the eastern end of the Campbellton Trail, a Native American path that ran through what is now the Atlanta area.
Europeans first learned of the mountain in 1597, when Spanish explorers were told of a mountain further inland which was "very high, shining when the sun set like a fire." By this time, the Stone Mountain area was inhabited by the Creek and (to a lesser extent) Cherokee peoples.
In the early 19th century, the area was known as Rock Mountain. After the founding of DeKalb County and the county seat of Decatur in 1822, Stone Mountain was a natural recreation area; it was common for young men to take their dates on horseback from Decatur to the mountain.
Entrepreneur Aaron Cloud built a 165 feet (50 m) wooden observation tower at the summit of the mountain in 1838, but it was destroyed by a storm and replaced by a much smaller tower in 1851. Visitors to the mountain would travel to the area by rail and road, and then walk up the 1.1-mile (1.8 km) mountaintop trail to the top, where Cloud also had a restaurant and club.
Granite quarrying started at Stone Mountain in the 1830s, but became a major industry following the completion of a railroad spur to the quarry site in 1847. This line was rebuilt by the Georgia Railroad in 1869. Over the years, Stone Mountain granite was used in many buildings and structures, including the locks of the Panama Canal, the steps to the East Wing of the United States Capitol and the Imperial Hotel in Tokyo. In recent years, granite suppliers in Georgia sent stone 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. Unfortunately, quarrying during earlier periods also destroyed several spectacular geological features on Stone Mountain, such as the Devil's Crossroads, which was located on top of the mountain.
In 1887 Stone Mountain was purchased for $45,000 by the Venable Brothers of Atlanta, who quarried the mountain for 24 more years, and descendents of the Venable family would retain ownership of the mountain until it was purchased by the State of Georgia in the 1950s.
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!"
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.
Some of the outdoor scenes for the Netflix's Stranger Things were filmed in the park in late 2015 and early 2016.
Aviation incidents
According to George Weiblen's annotated calendar for Monday, May 7, 1928: "Mail plane crashed on mountain at 8:00 P.M." The pilot, Johnny S. Kytle (1905 - 1931), not only survived the crash, but managed to grab the mail and walk down the mountain.
Around dusk on September 16, 2003, in clear weather, a small airplane circled the mountain five times, then crashed headlong into the south side, burst into flames and killed the pilot. A witness testifying at the NTSB investigation stated that the pilot, a 69-year-old accountant, had threatened on multiple occasions to commit suicide by flying into the mountain. The official NTSB accident report lists the probable cause as "The pilot's intentional flight into the ground for the purpose of suicide while impaired by alcohol."
Governance
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.
Places of interest
Confederate Hall, operated directly by the Stone Mountain Memorial Association or SMMA, is a museum that educates students and park guests on the geology and ecology of Stone Mountain as well as historical aspects of the area.

Broadcast tower
The short broadcast tower on the top of the mountain transmits two non-commercial stations: television station WGTV TV 8, and weather radio station KEC80 on 162.55 MHz. FM radio station WABE FM 90.1 was located on this tower from 1984 until 2005, when it was required to relocate to accommodate WGTV's digital conversion. W266BW FM 101.1 now has a permit as well. Atop the tower also sits the W4BOC Amateur Radio repeater which operates on a frequency on 146.760.
The tower is also used for the park's Project 25 two-way radio systems.
Scenic Railroad
Stone Mountain trails
Walk Up Trail: A 1.3-mile (2.1 km) trail to the top of Stone Mountain ascending 786 ft (240 m) in elevation to a height of 1,686 ft (514 m). The trail is steep, but spectacular panoramic views and cool winds await hikers at the top.
Cherokee Trail: A 5-mile (8 km) National Recreation Trail, the Cherokee Trail loops around the mountain base, with a mile section going up and over the west side of the mountain (crosses Walk Up Trail). Primarily passes through an oak-hickory forest, but views of the lakes, streams, and mountain are common.
Nature Garden Trail: A scenic 3/4 mile (1.2 km) loop trail through a mature oak-hickory forest community. Excellent for viewing shade-loving native plants. A small garden with interpretive native plant signs is at the entrance to the trail.
