A year later, the area around the milepost had developed into a settlement, first known as Terminus , and later Thrasherville , after a local merchant who built homes and a general store in the area. By 1842, the town had six buildings and 30 residents and was renamed Marthasville to honor Governor Wilson Lumpkin's daughter Martha. Later, John Edgar Thomson , Chief Engineer of
628-588: A city of the " New South " that would be based upon a modern economy and less reliant on agriculture. By 1885, the founding of the Georgia School of Technology (now the Georgia Institute of Technology ) and the Atlanta University Center , a consortium of historically Black colleges made up of units for men and women, had established Atlanta as a center for higher education. In 1895, Atlanta hosted
785-492: A decreasing portion of the population, from a high of 67% in 1990 to 54% in 2010. From 2000 to 2010, Atlanta gained 22,763 white residents, 5,142 Asian residents, and 3,095 Hispanic residents, while the city's Black population decreased by 31,678. Much of the city's demographic change during the decade was driven by young, college-educated professionals: from 2000 to 2009, the three-mile radius surrounding Downtown Atlanta gained 9,722 residents aged 25 to 34 and holding at least
942-571: A four-year degree, an increase of 61%. This was similar to the tendency in other cities for young, college educated, single or married couples to live in downtown areas. Between the mid-1990s and 2010, stimulated by funding from the HOPE VI program and under leadership of CEO Renee Lewis Glover (1994–2013), the Atlanta Housing Authority demolished nearly all of its public housing, a total of 17,000 units and about 10% of all housing units in
1099-463: A fragile ecosystem known as the Southern Appalachian spruce–fir forest . Fraser fir rarely occurs below 5,500 ft (1,700 m), and becomes the dominant tree type at 6,200 ft (1,900 m). By contrast, balsam fir is found from near sea level to the tree line in the northern Appalachians, but ranges only as far south as Virginia and West Virginia in the central Appalachians, where it
1256-713: A great thickness of sediment accumulated. Eventually, the tectonic forces pulling the two continents apart became so strong that an ocean formed off the eastern coast of the Laurentian margin. This was called the Iapetus Ocean and was the precursor of the modern Atlantic Ocean. The rocks of the Valley and Ridge province formed over millions of years, in the Iapetus. Shells and other hard parts of ancient marine plants and animals accumulated to form limey deposits that later became limestone. This

During the 1950s and 1960s, it became a major organizing center of the American civil rights movement , with Martin Luther King Jr. , Ralph Abernathy , and many other locals becoming prominent figures in the movement's leadership. In the modern era, Atlanta has remained a major center of transportation, with Hartsfield-Jackson International Airport becoming
1727-656: A new ocean opened up, the Rheic Ocean , during the Middle to Late Devonian, and subsequently its closure would result in the formation of the Alleghanian orogeny . As the continental plates moved closer together, fragments of oceanic crust, islands, and other continental masses collided with the eastern margin of ancestral North America. By this time, plants had appeared on land, followed by scorpions, insects, and amphibians. The ocean continued to shrink until, about 270 million years ago,

The evergreen great rhododendron ( Rhododendron maximum ) is characteristic of moist stream valleys. These occurrences are in line with the prevailing acidic character of most oak forest soils. In contrast, the much rarer chinquapin oak ( Quercus muehlenbergii ) demands alkaline soils and generally grows where limestone rock
2041-444: A number of serious insect and disease outbreaks. Among the most conspicuous is that of the introduced spongy moth ( Lymantria dispar ), which infests primarily oaks, causing severe defoliation and tree mortality. But it also has the benefit of eliminating weak individuals, and thus improving the genetic stock, as well as creating rich habitat of a type through accumulation of dead wood. Because hardwoods sprout so readily, this moth

Atlanta developed on a ridge south of the Chattahoochee River , which is part of the ACF River Basin . The river borders the far northwestern edge of the city, and much of its natural habitat has been preserved, in part by the Chattahoochee River National Recreation Area . Atlanta
11304-663: The Beltline has stimulated new and related development along its path. Under the Köppen classification , Atlanta has a humid subtropical climate ( Cfa ) with generous precipitation year-round, typical for the Upland South ; the city is situated in USDA Plant Hardiness Zone 8a, with the northern and western suburbs, as well as part of Midtown transitioning to 7b. Summers are hot and humid, with temperatures somewhat moderated by
11461-536: The Blue Ridge again reaches 2,000 ft (600 m) and higher. In the Virginia Blue Ridge, the following are some of the highest peaks north of the Roanoke River : Stony Man 4,031 ft (1,229 m), Hawksbill Mountain 4,066 ft (1,239 m), Apple Orchard Mountain 4,225 ft (1,288 m) and Peaks of Otter 4,001 and 3,875 ft (1,220 and 1,181 m). South of the Roanoke River, along
11618-658: The Blue Ridge, are Virginia's highest peaks including Whitetop Mountain 5,520 ft (1,680 m) and Mount Rogers 5,729 ft (1,746 m), the highest point in the Commonwealth. Chief summits in the southern section of the Blue Ridge are located along two main crests, the Western or Unaka Front along the Tennessee - North Carolina border and the Eastern Front in North Carolina, or one of several "cross ridges" between
11775-649: The Civil War ended in 1865, Atlanta was gradually rebuilt during the Reconstruction era . The work attracted many new residents. Due to the city's superior rail transportation network, the state capital was moved from Milledgeville to Atlanta in 1868. In the 1880 Census, Atlanta had surpassed Savannah as Georgia's largest city. Beginning in the 1880s, Henry W. Grady , the editor of the Atlanta Constitution newspaper, promoted Atlanta to potential investors as
11932-883: The Great Balsams. The Western Blue Ridge Front is subdivided into the Unaka Range , the Bald Mountains , the Great Smoky Mountains , and the Unicoi Mountains , and its major peaks include Roan Mountain 6,285 ft (1,916 m) in the Unakas, Big Bald 5,516 ft (1,681 m) and Max Patch 4,616 ft (1,407 m) in the Bald Mountains, Kuwohi 6,643 ft (2,025 m), Mount Le Conte 6,593 feet (2,010 m), and Mount Guyot 6,621 ft (2,018 m) in
12089-727: The Great Smokies, and Big Frog Mountain 4,224 ft (1,287 m) near the Tennessee- Georgia -North Carolina border. Prominent summits in the cross ridges include Waterrock Knob (6,292 ft (1,918 m)) in the Plott Balsams . Across northern Georgia, numerous peaks exceed 4,000 ft (1,200 m), including Brasstown Bald , the state's highest, at 4,784-and-4,696 ft (1,458-and-1,431 m) Rabun Bald . In north-central Alabama , Mount Cheaha rises prominently to 1,445 feet (440 m) over its surroundings, as part of
12246-595: The Pinnacle 3,007 feet (917 m) and Pidgeon Roost 3,400 ft (1,000 m). In West Virginia, more than 150 peaks rise above 4,000 ft (1,200 m), including Spruce Knob 4,863 ft (1,482 m), the highest point in the Allegheny Mountains . A number of other points in the state rise above 4,800 ft (1,500 m). Cheat Mountain ( Snowshoe Mountain ) at Thorny Flat 4,848 ft (1,478 m) and Bald Knob 4,842 ft (1,476 m) are among
12403-550: The US). Atlanta's dialect has traditionally been a variation of Southern American English . The Chattahoochee River long formed a border between the Coastal Southern and Southern Appalachian dialects. Because of the development of corporate headquarters in the region, attracting migrants from other areas of the country, by 2003, Atlanta magazine concluded that Atlanta had become significantly "de-Southernized". A Southern accent
12560-528: The USGS is "province", the same word as Canada uses to divide its political subdivisions, meaning that the terminology used by the two countries do not match below the region level. The lowest level of classification is "section". The Appalachian Uplands are one of the seven physiographic divisions in Canada . Canada's GSC does not use the same classification system as the USGS below the division level. The agency does break
12717-474: The United Kingdom and Germany. Bosnian refugees settled in Atlanta. Vietnamese people, Cambodians, Ethiopians and Eritreans were the earliest refugees formally brought to the city. Of the total population five years and older, 83.3% spoke only English at home, while 8.8% spoke Spanish, 3.9% another Indo-European language, and 2.8% an Asian language. Among them, 7.3% of Atlantans were born abroad ( 86th in
12874-433: The United States and Canada, and partly because the range was formed over numerous geologic time periods, one of which is sometimes termed the Appalachian orogeny , writing communities struggle to agree on an encyclopedic definition of the mountain range. However, each of the governments has an agency that informs the public about the major landforms that make up the countries, the United States Geological Survey (USGS) and
13031-538: The United States and is often called "City of Trees" or "The City in a Forest". Most of Atlanta was burned in the final months of the American Civil War, depleting the city of a large stock of its historic architecture. Yet architecturally, the city had never been traditionally "southern": Atlanta originated as a railroad town rather than a southern seaport dominated by the planter class, such as Savannah or Charleston . Because of its later development, many of
13188-570: The Wilbur and Hilda Glenn Family Foundation and Southern Company, Winship Cancer Institute launched the Winship Center for Cancer Health Equity Research in 2023 to focus research efforts on eliminating cancer disparities in Georgia and nationwide. Emory University Hospital is ranked one of "America’s Best Hospitals" for cancer by U.S. News & World Report . Atlanta Atlanta ( / æ t ˈ l æ n t ə / at- LAN -tə )
13345-488: The ability to relocate to the suburbs. As a result, the city began to make up an ever-smaller proportion of the metropolitan area's population. African-American veterans returned from World War II seeking full rights in their country and began heightened activism. In exchange for support by that portion of the Black community that could vote, in 1948 the mayor ordered the hiring of the first eight African-American police officers in
13502-485: The area from 1802 to 1825. The Creek were forced to leave the area in 1821, under Indian Removal by the federal government, and European American settlers arrived the following year. In 1836, the Georgia General Assembly voted to build the Western and Atlantic Railroad in order to provide a link between the port of Savannah and the Midwest . The initial route was to run southward from Chattanooga to
13659-525: The arrival of European settlers in North Georgia , the indigenous Creek people and their ancestors inhabited the area. Standing Peachtree , a Creek village where Peachtree Creek flows into the Chattahoochee River , was the closest Native American settlement to what is now Atlanta. Through the early 19th century, European Americans systematically encroached on the Creek of northern Georgia, forcing them out of
13816-586: The border of the coastal plain through the central and southern Atlantic states; and on the northwest, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains. A remarkable feature of the belt is the longitudinal chain of broad valleys, including the Great Appalachian Valley , which in the southerly sections divides the mountain system into two unequal portions, but in
13973-433: The city approved the $ 2.8 billion BeltLine project. It was intended to convert a disused 22-mile freight railroad loop that surrounds the central city into an art-filled multi-use trail and light rail transit line, which would increase the city's park space by 40%. The project stimulated retail and residential development along the loop, but has been criticized for its adverse effects on some Black communities. In 2013,
14130-460: The city in the following decade. During the 2000s, the city of Atlanta underwent a profound physical, cultural , and demographic change. As some of the African-American middle and upper classes also began to move to the suburbs, a booming economy drew numerous new migrants from other cities in the United States, who contributed to changes in the city's demographics. African Americans made up
14287-402: The city's economy to this day. In 2021, major freight railroad Norfolk Southern moved their headquarters to Atlanta, and the city hosts major classification yards for Norfolk Southern and CSX . Hartsfield–Jackson Atlanta International Airport is the world's busiest airport , and the headquarters of Delta Air Lines . Delta operates the world's largest airline hub at Hartsfield-Jackson and
14444-629: The city's elevation. Winters are overall mild but variable, occasionally susceptible to snowstorms even if in small quantities on several occasions, unlike the central and southern portions of the state. Warm air from the Gulf of Mexico can bring spring-like highs while strong Arctic air masses can push lows into the teens °F (−7 to −12 °C). July averages 80.9 °F (27.2 °C), with high temperatures reaching 90 °F (32 °C) on an average of 47 days per year, though 100 °F (38 °C) readings are not seen most years. January averages 44.8 °F (7.1 °C), with temperatures in
14601-597: The city's landmarks share architectural characteristics with buildings in the Northeast or Midwest, as they were designed at a time of shared national architectural styles. During the late 20th century, Atlanta embraced the global trend of modern architecture , especially for commercial and institutional structures. Examples include the State of Georgia Building built in 1966, and the Georgia-Pacific Tower in 1982. Many of
14758-409: The city's metro area, and the region hosts offices of over 1,250 multinational corporations. Many corporations are drawn to the city by its educated workforce; as of 2014 , 45% of adults aged 25 or older residing in the city have at least four-year college degrees, compared to the national average of 28%. Atlanta was born as a railroad town, and logistics continue to represent an important part of
14915-605: The city's role as a transportation center. The opening of the Georgia World Congress Center in 1976 further confirmed Atlanta's rise as a convention city. Construction of the city's subway system began in 1975, with rail service commencing in 1979. Despite these improvements, Atlanta lost more than 100,000 residents between 1970 and 1990, over 20% of its population. At the same time, it developed new office space after attracting numerous corporations, with an increasing portion of workers from northern areas. Atlanta
15072-443: The city's uptown district, is eight miles (13 km) north of Downtown and the city's third-largest business district. The district is marked by an urbanized core along Peachtree Road , surrounded by suburban single-family neighborhoods situated among woods and rolling hills. Surrounding Atlanta's three high-rise districts are the city's low- and medium-density neighborhoods , where the craftsman bungalow single-family home
15229-495: The city, stimulated by infrastructure improvements undertaken in preparation for the games. New development post-2000 has been aided by the Atlanta Housing Authority 's eradication of the city's public housing. As noted above, it allowed development of these sites for mixed-income housing, requiring developers to reserve a considerable portion for affordable housing units. It has also provided for other former residents to be given vouchers to gain housing in other areas. Construction of
15386-477: The city. After reserving 2,000 units mostly for elderly, the AHA allowed redevelopment of the sites for mixed-use and mixed-income, higher density developments, with 40% of the units to be reserved for affordable housing. Two-fifths of previous public housing residents attained new housing in such units; the remainder received vouchers to be used at other units, including in suburbs. At the same time, in an effort to change
15543-611: The city. Much controversy preceded the 1956 Sugar Bowl , when the Pitt Panthers , with African-American fullback Bobby Grier on the roster, met the Georgia Tech Yellow Jackets . There had been controversy over whether Grier should be allowed to play due to his race, and whether Georgia Tech should even play at all due to Georgia's Governor Marvin Griffin 's opposition to racial integration. After Griffin publicly sent
15700-513: The construction of the Equitable , Flatiron , Empire , and Candler buildings. Sweet Auburn emerged as a center of Black commerce. The period was also marked by strife and tragedy. Increased racial tensions led to the Atlanta Race Riot of 1906, when Whites attacked Blacks, leaving at least 27 people dead and over 70 injured, with extensive damage in Black neighborhoods. In 1913, Leo Frank ,
15857-457: The continent that are now exposed. The first mountain-building tectonic plate collision that initiated the construction of what are today the Appalachians occurred at least a billion years ago when the pre-North American craton called Laurentia collided with at least one other craton - Amazonia . All the other cratons of the earth also collided at about this time to form the supercontinent Rodinia and were surrounded by one single ocean. (It
16014-641: The continents that were ancestral to North America and Africa collided during the formation of the supercontinent Pangea . Because North America and Africa were once geographically connected, the Appalachians formed part of the same mountain chain as the Little Atlas in Morocco . This mountain range, known as the Central Pangean Mountains , extended into Scotland , before the Mesozoic Era opening of
16171-453: The culture of those receiving subsidized housing, the AHA imposed a requirement for such residents to work (or be enrolled in a genuine, limited-time training program). It is virtually the only housing authority to have created this requirement. To prevent problems, the AHA also gave authority to management of the mixed-income or voucher units to evict tenants who did not comply with the work requirement or who caused behavior problems. In 2005,
16328-412: The deciduous needle-leaf conifer, the tamarack , or eastern larch ( Larix laricina ). The dominant northern and high elevation conifer is the red spruce ( Picea rubens ), which grows from near sea level to above 4,000 ft (1,200 m) above sea level (asl) in northern New England and southeastern Canada. It also grows southward along the Appalachian crest to the highest elevations of
16485-413: The destruction of all public buildings and possible assets that could be of use to the Union Army. On the next day, Mayor James Calhoun surrendered Atlanta to the Union Army, and on September 7, Sherman ordered the city's civilian population to evacuate. On November 11, 1864, Sherman prepared for the Union Army's March to the Sea by ordering the destruction of Atlanta's remaining military assets. After
16642-506: The divisions of the Appalachian Uplands into 13 subsections that are in four different political provinces of Canada. While the Appalachian Highlands and Appalachian Uplands are generally continuous across the U.S./Canadian border, the St. Lawrence Valley area is handled differently in the physiographic classification schemas. The part of the St. Lawrence Valley in the United States is one of
16799-529: The driest sites are dominated by chestnut oak, or sometimes by scarlet or northern red oaks. In the northern Appalachians the oaks, except for white and northern red, drop out, while the latter extends farthest north. The oak forests generally lack the diverse small tree, shrub and herb layers of mesic forests. Shrubs are generally ericaceous , and include the evergreen mountain laurel ( Kalmia latifolia ), various species of blueberries ( Vaccinium spp.), black huckleberry ( Gaylussacia baccata ),
16956-440: The early 19th century, Washington Irving proposed renaming the United States either Appalachia or Alleghania. In U.S. dialects in the southern regions of the Appalachians, the word is pronounced / ˌ æ p ə ˈ l æ tʃ ɪ n z / , with the third syllable sounding like "latch". In northern parts of the mountain range, it is pronounced / ˌ æ p ə ˈ l eɪ tʃ ɪ n z / or / ˌ æ p ə ˈ l eɪ ʃ ɪ n z / ;
17113-425: The folds and faults created many millions of years earlier. Other streams downcut so rapidly that they cut right across the resistant folded rocks of the mountain core, carving canyons across rock layers and geologic structures. The Appalachian Mountains contain major deposits of anthracite coal as well as bituminous coal . In the folded mountains the coal is in metamorphosed form as anthracite , represented by
17270-480: The land mass that is now New England and southwestward to Pennsylvania. The Taconic Orogeny was the second of four mountain building plate collisions that contributed to the formation of the Appalachians, culminating in the collision of North America and Africa (see Alleghanian orogeny ). The third mountain-building event was the Acadian orogeny which occurred between 375 and 359 million years ago. The Acadian orogeny
17427-430: The last building designed by noted architect Marcel Breuer . Atlanta is divided into 242 officially defined neighborhoods . The city contains three major high-rise districts, which form a north–south axis along Peachtree : Downtown , Midtown , and Buckhead . Surrounding these high-density districts are leafy, low-density neighborhoods, most of which are dominated by single-family homes. Downtown Atlanta contains
17584-469: The latter. However, balsam fir also does well in soils with a pH as high as 6. Eastern or Canada hemlock ( Tsuga canadensis ) is another important evergreen needle-leaf conifer that grows along the Appalachian chain from north to south but is confined to lower elevations than red spruce and the firs. It generally occupies richer and less acidic soils than the spruce and firs and is characteristic of deep, shaded and moist mountain valleys and coves . It
17741-583: The longest paved trail surface in the U.S. totaling about 300 miles (480 km). Atlanta's cultural offerings expanded during the 2000s: the High Museum of Art doubled in size; the Alliance Theatre won a Tony Award ; and art galleries were established on the once-industrial Westside . The College Football Hall of Fame relocated to Atlanta and the National Center for Civil and Human Rights museum
17898-486: The majority of Atlanta's foreign-born population. The city's Italians included immigrants from northern Italy, many of whom had been in Atlanta since the 1890s; more recent arrivals from southern Italy; and Sephardic Jews from the Isle of Rhodes, which Italy had seized from Turkey in 1912. Europeans from Great Britain , Ireland and Germany settled in the city as early as the 1840s. Most of Atlanta's European population are from
18055-528: The microclimates that best suited them. The flora of the Appalachians are diverse and vary primarily in response to geology, latitude, elevation and moisture availability. Geobotanically, they constitute a floristic province of the North American Atlantic Region . The Appalachians consist primarily of deciduous broad-leaf trees and evergreen needle-leaf conifers, but also contain the evergreen broad-leaf American holly ( Ilex opaca ), and
18212-752: The more notable peaks in West Virginia. The Blue Ridge Mountains , rising in southern Pennsylvania and there known as South Mountain , attain elevations of about 2,000 ft (600 m) in Pennsylvania. South Mountain achieves its highest point just below the Mason-Dixon line in Maryland at Quirauk Mountain 2,145 ft (654 m) and then diminishes in height southward to the Potomac River . Once in Virginia ,
18369-769: The most notable examples from this period were designed by world renowned Atlanta architect John Portman . Most of the buildings that define the downtown skyline were designed by Portman during this period, including the Westin Peachtree Plaza and the Atlanta Marriott Marquis . In the latter half of the 1980s, Atlanta became one of the early homes of postmodern buildings that reintroduced classical elements to their designs. Many of Atlanta's tallest skyscrapers were built in this period and style, displaying tapering spires or otherwise ornamented crowns, such as One Atlantic Center (1987), 191 Peachtree Tower (1991), and
18526-425: The most office space in the metro area, much of it occupied by government entities. Downtown is home to the city's sporting venues and many of its tourist attractions. Midtown Atlanta is the city's second-largest business district, containing the offices of many of the region's law firms. Midtown is known for its art institutions, cultural attractions, institutions of higher education, and dense form. Buckhead ,
18683-450: The most severe occurring on January 7, 1973. Tornadoes are rare in the city itself, but the March 14, 2008, EF2 tornado damaged prominent structures in downtown Atlanta. The 2020 United States census reported that Atlanta had a population of 498,715. The population density was 3,685.45 persons per square mile (1,422.95/ km ). The racial and ethnic makeup of Atlanta (including Hispanics)
18840-745: The mountainous belt just north of the New River in Virginia. South of the New River, rivers head into the Blue Ridge, cross the higher Unakas, receive important tributaries from the Great Valley, and traversing the Cumberland Plateau in spreading gorges ( water gaps ), escape by way of the Cumberland River and the Tennessee River rivers to the Ohio River and the Mississippi River, and thence to
18997-538: The mountainous belt, and thus the main lines of drainage run from north to south, exemplified by the Hudson River . However, the valley through which the Hudson River flows was cut by the gigantic glaciers of the ice ages —the same glaciers that deposited their terminal moraines in southern New York and formed the east–west Long Island . The Appalachian region is generally considered the geographical divide between
19154-472: The movement's leadership. While Atlanta in the postwar years had relatively minimal racial strife compared to other cities, Blacks were limited by discrimination, segregation, and continued disenfranchisement of most voters. In 1961, the city attempted to thwart blockbusting by realtors by erecting road barriers in Cascade Heights , countering the efforts of civic and business leaders to foster Atlanta as
19311-488: The much larger Atlanta metropolitan area , the core of which includes Cobb , Clayton and Gwinnett counties, in addition to Fulton and DeKalb. Metro Atlanta is home to more than 6.3 million people (2023 estimate), making it the sixth-largest U.S. metropolitan area . Situated among the foothills of the Appalachian Mountains at an elevation of just over 1,000 feet (300 m) above sea level, Atlanta features unique topography that includes rolling hills, lush greenery, and
19468-432: The name of the tribe to the mountains themselves. The first cartographic appearance of Apalchen is on Diego Gutiérrez 's map of 1562; the first use for the mountain range is the map of Jacques le Moyne de Morgues in 1565. The name was not commonly used for the whole mountain range until the late 19th century. A competing and often more popular name was the "Allegheny Mountains", "Alleghenies", and even "Alleghania". In
19625-461: The northernmost lies west of all the ranges possessing typical Appalachian features, and separates them from the Adirondack group. The mountain system has no axis of dominating altitudes, but in every portion, the summits rise to rather uniform heights, and, especially in the central section, the various ridges and intermontane valleys have the same trend as the system itself. None of the summits reaches
19782-424: The oceans, but there were no plants or animals on land. Then, during the middle Ordovician Period about 500 to 470 million years ago, the motion of the crustal plates changed, and the continents began to move back toward each other. The once-quiet Appalachian passive margin changed to a very active plate boundary when a neighboring Iapetus oceanic plate containing a volcanic arc collided with and began sinking beneath
19939-574: The population was living below the poverty line in 2022. Circa 2024, of the Atlanta residents, 391,711 of them lived in Fulton County and 28,292 of them lived in DeKalb County. In the 1920s, the Black population began to grow in Southern metropolitan cities like Atlanta, Birmingham , Houston , and Memphis . The New Great Migration brought an insurgence of African Americans from California and
20096-585: The project received a federal grant of $ 18 million to develop the southwest corridor. In September 2019 the James M. Cox Foundation gave $ 6 Million to the PATH Foundation which will connect the Silver Comet Trail to The Atlanta BeltLine which is expected to be completed by 2022. Upon completion, the total combined interconnected trail distance around Atlanta for The Atlanta BeltLine and Silver Comet Trail will be
20253-414: The proportion of whites in the city had strong growth. In two decades, Atlanta's White population grew from 33% to 39% of the city's population. Whites made up the majority of new Atlanta residents between 2010 and 2020. The Hispanic and Latino populations of metro Atlanta have grown significantly in recent years. The largest Hispanic ancestries in Atlanta are Mexican , Puerto Rican and Cuban . There
20410-455: The region of perpetual snow. In Pennsylvania , there are over sixty summits that rise over 2,500 ft (800 m); the summits of Mount Davis and Blue Knob rise over 3,000 ft (900 m). In Maryland, Eagle Rock and Dans Mountain are conspicuous points reaching 3,162 and 2,882 ft (964 and 878 m) respectively. On the same side of the Great Valley, south of the Potomac, are
20567-506: The region was created when the continents of Laurentia and Amazonia collided, creating a supercontinent called Rodinia . The collision of these continents caused the rocks to be folded and faulted, creating the first mountains in the region. Many of the rocks and minerals that were formed during that event can currently be seen at the surface of the present Appalachian range. Around 480 million years ago, geologic processes began that led to three distinct orogenic eras that created much of
20724-482: The result of volcanic activity that occurred around this time. Evidence of subsurface activity, dikes and sills intruding into the overlying rock, is present in the Blue Ridge as well. For instance, mafic rocks have been found along the Fries Fault in the central Blue Ridge area of Montgomery County, VA. The Iapetus continued to expand and during that time bacteria, algae, and many species of invertebrates flourished in
20881-519: The ridges are not high, the terrain is extremely rugged. In Ohio and New York, some of the plateau has been glaciated , which has rounded off the sharp ridges and filled the valleys to some extent. The glaciated regions are usually referred to as hill country rather than mountains. The Appalachian belt includes the plateaus sloping southward to the Atlantic Ocean in New England , and southeastward to
21038-401: The same time, Atlanta is home to a sizable foreign-born Black population, notably from Eritrea , Ethiopia , Ghana , Somalia , Liberia , and Nigeria . With many notable investments occurring in Atlanta initiated by the 1996 Summer Olympics , the non-Hispanic white population of Atlanta began to rebound after several decades of white flight to Atlanta's suburbs. Between 2000 and 2020,
21195-495: The second-level classifications, part of the Appalachian Highlands. In Canada, the area is part of the first-level classification, the St. Lawrence Lowlands . This includes the area around the city of Montreal, Anticosti Island , and the northwest coastline of Newfoundland. The dissected plateau area, while not actually made up of geological mountains, is popularly called "mountains", especially in eastern Kentucky and West Virginia, and while
21352-416: The southern Appalachians, as in North Carolina and Tennessee . In the central Appalachians it is usually confined above 3,000 ft (900 m) asl, except for a few cold valleys in which it reaches lower elevations. In the southern Appalachians, it is restricted to higher elevations. Another species is the black spruce ( Picea mariana ), which extends farthest north of any conifer in North America,
21509-413: The southern and central Appalachians consist largely of black , northern red , white , chestnut and scarlet oaks ( Quercus velutina, Q. rubra, Q. alba, Q. prinus and Q. coccinea ) and hickories, such as the pignut ( Carya glabra ) in particular. The richest forests, which grade into mesic types, usually in coves and on gentle slopes, have predominantly white and northern red oaks, while
21666-511: The southern and central Appalachians at low and intermediate elevations. In the northern Appalachians and at higher elevations of the central and southern Appalachians these diverse mesic forests give way to less diverse northern hardwood forests with canopies dominated only by American beech, sugar maple, American basswood ( Tilia americana ) and yellow birch and with far fewer species of shrubs and herbs. Drier and rockier uplands and ridges are occupied by oak–chestnut forests dominated by
21823-535: The southernmost spur of the Blue Ridge Mountains. Sources written prior to the recognition of the concept of physiographic regions divided the Appalachian Mountains into three major sections: Plate tectonics over the period dating back at least 1 billion years led to geological creation of the land that is now the Appalachian Mountain range. The continental movement led to collisions that built mountains and they later pulled apart creating oceans over parts of
21980-413: The suburbs slightly cooler due largely to the urban heat island effect. Lows at or below freezing can be expected 36 nights annually, but the last occurrences of temperatures below 10 °F (−12 °C) were December 24, 2022 , and January 2014 , eight years apart. Extremes range from −9 °F (−23 °C) on February 13, 1899 to 106 °F (41 °C) on June 30, 2012 . Average dewpoints in
22137-704: The summer range from 63.7 °F (17.6 °C) in June to 67.8 °F (19.9 °C) in July. Typical of the southeastern U.S., Atlanta receives abundant rainfall that is evenly distributed throughout the year, though late spring and early fall are somewhat drier. The average annual precipitation is 50.43 in (1,281 mm), while snowfall is typically light and rare with a normal of 2.2 inches (5.6 cm) per winter. The heaviest single snowfall occurred on January 23, 1940, with around 10 inches (25 cm) of snow. However, ice storms usually cause more problems than snowfall does,
22294-564: The surface structure seen in today's Appalachians. During this period, mountains once reached elevations similar to those of the Alps and the Rockies before natural erosion occurred over the last 240 million years leading to what is present today.
