Stone Mountain is a quartz monzonite dome monadnock and the site of Stone Mountain Park, near the city of Stone Mountain, Georgia. The park is owned by the state of Georgia and managed by Norcross-based Herschend Family Entertainment. 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 depicts three Confederate leaders, Jefferson Davis, Robert E. Lee, and Stonewall Jackson.

Stone Mountain was once owned by the Venable Brothers, "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. By 2015, it was the most visited destination in the state of Georgia.

Skyrides on Stone Mountain

The mountain, which ranges in composition from quartz monzonite to granite and granodiorite, 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.

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.

The 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 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.

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 (on 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 is 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) into the mountain's surface.

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, 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." Three weeks later, Georgian John Temple Graves, editor of the New York American, suggested it should have a 70-foot (21 m) statue of Robert E. Lee.

The project was greatly advanced by Mrs. C. Helen Plane, a charter member of the United Daughters of the Confederacy (UDC) and first president and Honorary Life President of the Georgia State Division. After obtaining the approval of the Georgia UDC, she set up the UDC Stone Mountain Memorial Association. She chose the sculptor Gutzon Borglum for the project and invited him to visit the mountain (although, despite his Ku Klux Klan involvement, she "would not shake his hand—he was, after all, a Yankee"). She met him at the Atlanta train station, took him to her family's summer home, Mont Rest, at the foot of the mountain, and introduced him to Sam Venable, another active Klan member and owner of the mountain. Borglum also enlisted Luigi Del Bianco, whom he would also involve in Mount Rushmore.

Borglum's original plan was: 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.

Venable deeded the north face of the mountain to the UDC in 1916, on condition that it complete a sizable Civil War monument in 12 years. Finances as well as technical problems slowed progress. The US Mint issued a 1925 Commemorative silver US half dollar, bearing the words "Stone Mountain", as a fundraiser for the monument. 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. He destroyed his models, claiming that they were his property, but the Association disagreed and had a warrant issued for his arrest. He was warned of the arrest and narrowly escaped to North Carolina, whose governor, Angus McLean, refused to extradite him, though he could not return to Georgia. The affair was highly publicized and there was much discussion and discord, including discord between Sam Venable, the Association, and its president Hollins Randolph. The face of Lee that Borglum had partially completed was blasted off the mountain in 1928.

Borglum's next major project was Mount Rushmore.

After a number of sculptors turned them down, Augustus Lukeman took up the work in 1925, with a different, smaller design. Fundraising was even more difficult after the public debate and name-calling, and work stopped in 1928. In 1941 segregationist Governor Eugene Talmadge formed the Stone Mountain Memorial Association (SMMA) to continue work on the memorial, but the project was delayed once again by the U.S. entry into World War II (1941–45).

In response to Brown v. Board of Education of 1954 and the birth of the Civil Rights Movement, in 1958, at the urging of segregationist Governor Marvin Griffin, the Georgia legislature approved a measure to purchase Stone Mountain at a price of $1.125 million. In 1963 Walker Hancock was selected to complete the carving, and work began in 1964. The carving was dedicated in a ceremony on May 9, 1970. 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.

Stone Mountain Park officially opened on April 14, 1965 – 100 years to the day after Lincoln's assassination. Four flags of the Confederacy are flown at the site. 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."

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 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 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.


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 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. Under terms of a 1999 agreement, Norcross, Georgia-based Herschend pays the state of Georgia $11 million annually. The park is the largest attraction operated by privately-held Herschend, which also manages several dozen other attractions including Dollywood in Pigeon Forge, Tennessee, and Silver Dollar City in Branson, Missouri. The company's CEO said in a 2012 news interview that the contract to operate Stone Mountain extended another 35 years.

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 (2.1 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 is a 5-mile (8 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 34 mile (1.2 km) 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 (1.6 km). The field trail is a birding spot and the woodland trail provides shade and numerous native plants. Dogs are not allowed.

Park attractions

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 manor-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.

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, 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.) 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.

The since-retired Riverboat offered a scenic cruise aboard a reproduction of a Mississippi riverboat on 363-acre (147 ha) Stone Mountain Lake.

On summer evenings the mountain hosts the Stone Mountain Laser Show Spectacular, a fireworks and laser light 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.
