Mountain and park in Georgia, United States
the mountain in the U. S. state of Georgia

Stone Mountain is a quartz monzonite dome monadnock and the site of Stone Mountain Park, east of Atlanta, Georgia. Outside the park is the small city of Stone Mountain, Georgia. The park is the most visited tourist site in the state of Georgia. The park is owned by the state of Georgia. At its summit, the elevation is 1,686 feet (514 m) above sea level and 825 feet (251 m) above the surrounding area. Stone Mountain is well known for not only its geology, but also the enormous rock relief on its north face, the largest bas relief artwork in the world. The carving, completed in 1972, depicts three Confederate leaders, Jefferson Davis, Robert E. Lee, and Stonewall Jackson. Stone Mountain, once owned by the Venable Brothers, was seen from the outset "as a memorial to the Confederacy." Stone Mountain Park officially opened on April 14, 1965 – 100 years to the day after Lincoln's assassination, although the park had already been in use for a few years. The mountain, which ranges in composition from quartz monzonite to granite and granodiorite, is more than 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.

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 below the surface. The Stone Mountain pluton continues underground 9 mile (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 farther south of Stone Mountain.

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 on 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. These vernal pools are also home to several federally listed rare and endangered plant species, such as black spored quillwort (Isoetes melanospora) and pool sprite (also called snorkelwort, Gratiola amphiantha). 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 Confederate yellow daisy (Helianthus porteri) flowers appear on the mountain, growing in rock crevices and in the large wooded areas. More than 120 wildflowers, most of them native to the Southern Appalachians and including several rare or federally protected species, have been identified on the mountain.

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 (on their favorite horses, Blackjack, Traveller, and Little Sorrel, respectively). The sculpture was cut 42 feet (13 m) deep into the mountain, measures 90 feet (27 m) in height and 190 feet (58 m) in width, and lies 400 feet (122 m) above the ground. David Freeman, writing on the origins of the memorial, states: "Who first conceived of a Confederate memorial on the side of Stone Mountain has long been a matter of debate The written evidence points to Francis Ticknor, a nineteenth century physician and poet from Jones County, Georgia in an 1869 poem William H. Terrell, an Atlanta attorney and son of a Confederate veteran, suggested it publicly on May 26, 1914 in an editorial for the Atlanta Constitution." a charter member of the United Daughters of the Confederacy (UDC) and first president and Honorary Life President of the Georgia State Division. Borglum's original plan was having five groups of figures, sixty five mounted officers representing the states (to be chosen by the states), General Nathan Bedford Forrest and his cavalry—some 700 to 1,000 figures, each from 35 feet (11 m) to 50 feet (15 m) high. In addition, Borglum planned a room cut 60 feet (18 m) into the mountain, 320 feet (98 m) wide, and 40 feet (12 m) high, faced by 13 columns. This issue, which required the approval of both the 1926 Congress and President Calvin Coolidge, was the largest issue of commemorative coins by the U. S. government up to that time. Financial conflicts between Borglum and the Association led to his firing in 1925. The carving was completed by Roy Faulkner on March 3, 1972. Faulkner in 1985 opened the Stone Mountain Carving Museum (now closed) on nearby Memorial Drive commemorating the carving's history. An extensive archival collection related to the project is now at Emory University, with the bulk of the materials dating from 1915 to 1930; the finding aid provides a history of the project, and an index of the papers contained in the collection. The Stone Mountain Memorial Lawn "contains thirteen terraces—one for each Confederate state Each terrace flies the flag that the state flew as member of the Confederacy."

In 1963, there opened beneath the sculpture a replica plantation, where slave quarters were described as "neat" and "well furnished" in promotional materials. The slaves were called "hands" or "workers," and black actress Butterfly McQueen (from Gone with the Wind) was hired to guide and inform visitors. The park states that the plantation was inspired by Gone with the Wind. The plantation has been renamed Historic Square.

According to sociologist James W. Loewen, Stone Mountain was "the sacred site to members of the second and third national klans." Loewen alleges that the rebirth of the Ku Klux Klan—the second Klan—was inspired by D. W. Griffith's 1915 Klan glorifying film, The Birth of a Nation. It was followed in August by the highly publicized lynching of Leo Frank, who had been convicted of murder, in nearby Marietta, Georgia. Loewen further alleges that on November 25 of the same year, Thanksgiving Day, a small group, including fifteen robed and hooded "charter members" of the new organization, met at the summit of Stone Mountain to create a new iteration of the Klan. Led by William J. Simmons, it included two elderly members of the original Klan. As part of their ceremony, they set up on the summit an altar covered with a flag, opened a Bible, and burned a 4.88 m cross. James R. Venable attended the 1915 revival of the KKK on top of Stone Mountain and later became an Imperial Wizard of the National Knights of the Ku Klux Klan, which was one of the later KKK factions. He owned land at the base of the mountain that he had inherited from his ancestors, and in October 1923 he granted the Klan an easement with perpetual right to hold celebrations as they desired. However, the property was condemned in 1960 at the behest of the Stone Mountain Memorial Association. The Klan also held cross burnings at the summit of the mountain on different occasions from 1915 onward. This practice came to an end in 1962, when the Klan attempted to hold a mountaintop cross burning in response to the NAACP holding its national convention in Atlanta. The UDC established the Stone Mountain Confederate Memorial Association (SMCMA) for fundraising and on site supervision of the project. Venable and Borglum, 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 $250,000 (~$ in ) raised, part came from the federal government, which in 1925 issued commemorative fifty cent coins with the soldiers Robert E. Lee and Stonewall Jackson on them. The image on the verso of the coin was based on The Last Meeting of Lee and Jackson, executed in 1869 by Everett B. D. Fabrino Julio, itself an icon of Lost Cause mythology; it is now in the American Civil War Museum (until 2012 the Museum of the Confederacy). When the state completed the purchase in 1960, it condemned the property to void Venable's agreement to allow the Klan perpetual right to hold meetings on the premises. This controversy was stimulated by a movement in other states to remove the Confederate battle flag and statues of Confederate leaders from public areas. quotation|[The Confederate sculpture at Stone Mountain is] the largest shrine to white supremacy in the history of the world I don't think people understand the objective and the intent. They don't understand that it's based on white supremacy because the [American Civil War] was based on white supremacy, and the 'heroes' are based on white supremacy. After the killings at Emanuel Church in Charleston, it finally crystallized for me that these monuments encourage violence and validate oppression.|source=President of the NAACP Richard Rose However, this would require the approval of the Georgia Legislature, as would any change to a "military monument" in the state. On October 11, 2015, The Atlanta Journal Constitution reported the park was considering a proposal of a permanent "Freedom Bell" honoring Martin Luther King Jr. and the line "Let freedom ring from Stone Mountain of Georgia", from King's 1963 "I Have a Dream" speech. The proposed monument is inspired by a bell ringing ceremony held in 2013 honoring the 50th anniversary of King's speech. It is not supported by the NAACP or King founded Southern Christian Leadership Conference (SCLC), who want the Confederate symbols removed rather than a King symbol added. Advance Local reported in 2015 that both the DeKalb County branch of the NAACP and the Sons of Confederate Veterans were opposed to the bell because it would have been put next to a Confederate monument. Representatives of the NAACP were quoted in the article saying "It's an attempt to gain support from blacks to keep these racist and demeaning symbols." In August 2017, after the Unite the Right rally in Charlottesville, Virginia—a white nationalist protest against the removal of the Robert E. Lee monument and Stonewall Jackson sculpture—turned violent, many people across the country again demanded the removal of Confederate monuments and memorials as part of a national political debate. Georgia State Representative and Democratic gubernatorial candidate Stacey Abrams called for the removal, by sandblasting, of Stone Mountain's carving. She called it "a blight upon our state". On July 5, 2020, 100 to 200 armed protesters came to Stone Mountain to call for the carving's removal. Known as the Not Fucking Around Coalition (NFAC), it was a protest against both overt and systemic racism, calling out white supremacists, with the location being chosen in part due to its history as the place where the Ku Klux Klan was re formed. On August 15, 2020, the park administration temporarily closed its gates in reaction to a gathering of white nationalists planned there, and the city's public buses were suspended for the day. Nevertheless, a fight broke out downtown between groups of white supremacists, Black Lives Matter counter protestors, and people who wish to keep Confederate monuments in place, though no injuries were reported.

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 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 1567, when Spanish explorers were told of a mountain farther 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 couples on dates to ride to the mountain on horseback. The mountain is easy to climb and there has been a path since the nineteenth century. Entrepreneur Aaron Cloud built a 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 (2 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 group responsible for planning the Martin Luther King Jr. Memorial in Washington, D. C.; the foundation later chose to use granite imported from China. 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 descendants of the Venable family would retain ownership of the mountain until it was purchased by the State of Georgia in 1958. Martin Luther King Jr. mentioned the monument in his "I Have a Dream" speech at the August 1963 March on Washington for Jobs and Freedom, 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 series Stranger Things were filmed in the park.

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, crashed headlong into the south side, and burst into flames. The pilot was killed. 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."

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. As of August, 2022, the board entered a 10 year contract (with the option to renew for up to 30 years) with Thrive Attractions Management Group, LLC, to operate park attractions. The Stone Mountain Memorial Association retains ownership, while Thrive keeps 2% of the annual gross revenues from the park's hotels and 3% of gross revenues from other areas. From 1999 to 2022, park attractions were managed by Herschend Family Entertainment Corporation, which had a 30 year contract to operate attractions. Under terms of a 1999 agreement, Herschend paid the state of Georgia $11 million (~$ in ) annually, while the Stone Mountain Memorial Association had the right to reject any project deemed unfit. In 2018, Herschend Family Entertainment Corporation decided to end their contract early after only 20 years due to record losses in 2017 and 2018, citing decreased revenues and “protests and division” fueled by the park’s ubiquitous Confederate imagery as factors. Bids for a new management company for Stone Mountain Park were submitted in October 2021. Thrive Attractions Management Group, LLC, started by the previous Vice President of Herschend Family Entertainment Corporation and general manager of Stone Mountain Park for 10 years, Michael Dombrowski, submitted the only bid to the Mountain Memorial Association, which was approved on May 23, 2022. A small theater shows a historical documentary about the Civil War in Georgia called The Battle for Georgia. The education department is host to thousands of students each school year, teaching the subjects of geology, ecology, and history. Classes are designed to meet the Georgia Performance Standards and the North American Association for Environmental Education guidelines. Historic Square (formerly The Antebellum Plantation and Farmyard) is an open air museum composed of 19 historic buildings, built between 1790 and 1875, that have been re erected on the site to represent a pre Civil War Georgia plantation. The historic houses have been furnished with an extensive collection of period furniture and decorations. The farm features a petting zoo. A grist mill dates from 1869 and was moved to the park in 1965. A covered bridge dates from 1892 and originally spanned the Oconee River in Athens, Georgia. The park provides daily concerts on a large carillon that originated at the 1964 New York World's Fair. The instrument consists of 732 bell tone rods, electronically amplified through 60 speakers in a decorative 13 story structure.

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 of 146.760 MHz. The tower is also used for the park's Project 25 two way radio systems.

Walk Up Trail is a 1.3 mile (2 km) trail to the top of Stone Mountain ascending 786 feet (240 m) in elevation to a height of 1686 feet (514 m). The trail is steep, but spectacular panoramic views and cool winds await hikers at the top. Cherokee Trail is an 8 mile (13 km) National Recreation Trail. It loops around the mountain base, with a mile section going up and over the west side of the mountain (crosses Walk Up Trail). It passes primarily through an oak hickory forest, but views of the lakes, streams, and mountain are common. Nature Garden Trail is a scenic loop trail through a mature oak hickory forest community, it is excellent for viewing shade loving native plants. A small garden with interpretive native plant signs is at the entrance to the trail. Songbird Habitat Trails comprise two loop trails each running 1 mile (2 km). The field trail is a birding spot and the woodland trail provides shade and numerous native plants. Dogs are not allowed.

The park features several attractions that are operated by Herschend Family Entertainment Corporation. The Skyride, a Swiss built cable car to the summit of the mountain, passes by the carving on the way up. Historic Square is a collection of historic buildings relocated from around the state of Georgia, including three plantation houses dating from 1794, 1850 and 1845; two slave cabins; a barn; and other outbuildings. The Historic Square Farmyard features historic breeds of sheep, goats and pigs. Atlanta architect James Means, investor Christie Bell Kennedy, and antiques dealer Kenneth Garcia chose, moved, arranged, altered, and decorated the buildings between 1960 and 1963. Modeled after Colonial Williamsburg, the commercial concession originally opened as the "Antebellum Plantation." Crossroads is a recreation of an 1872 Southern town with several attractions that include a modern 4 D movie theater, an adventure mini golf course and a duck tour ride. The duck boats have been replaced by the Rockin’ Land and Lake Tour in 2019 due to several deaths in other locations caused by duck boat accidents. The tour includes a ride on a double decker open top bus and a pontoon boat ride at the marina. There are stores and restaurants. Craft demonstrators include glass blowing and candy making. The Dinotorium is a children's activity area that features 65 interactive games, climbing structures, trampoline floors and slides. Sky Hike is a family ropes adventure course; Geyser Towers is a playground featuring a large fountain at the entrance. On summer evenings, the mountain hosts the Stone Mountain Laser Show Spectacular, a fireworks and laser lighting display. The laser light show projects images of the Deep South as well as Georgia history onto the Confederate Memorial carving. During Memorial Day Weekend of 2011, Stone Mountain unveiled its overhaul of the laser show, dubbed Mountainvision, which incorporates digital projections, lasers, special effects, and pyrotechnics.

Monument: The Untold Story of Stone Mountain is a 2022 documentary made by the Atlanta History Center.
