An estimated 1,073 miles (1,727 km) of streams in the park support fish. The brook trout is

6789-428: The park service has sponsored a program that pays individuals to hunt and kill boars and leave their bodies in locations frequented by bears. The Smokies are home to a diverse bird population due to the presence of multiple forest types. Nearly 120 bird species are known to use the park as a breeding ground, including 52 from the neotropics and additional ones from northern climatic regions. Other migratory species use

6882-418: The park. Plants and animals common in the country's Northeast have found suitable ecological niches in the park's higher elevations, while southern species find homes in the balmier lower reaches. The forests of the Smokies are typically divided into three zones—The cove hardwood forests in the stream valleys, coves, and lower mountain slopes; the northern hardwood forests on the higher mountain slopes; and

6975-415: The rainy and temperate climate. No other location of similar size within a temperate climate is known to match the park's biodiversity. Forests cover approximately 95 percent of the Great Smoky Mountains National Park. The lower region forests are dominated by deciduous leafy trees. At higher altitudes, deciduous forests give way to coniferous trees like Fraser fir . An estimated 20 to 25 percent of

7068-456: The range lacks the tree line found at lower elevations in the northern half of the Appalachian range. Statistical modelling predicts that the alpine tree line would exist at above 7,985 feet (2434 m) in the climate zone and latitude of the southern Appalachians. The highest parts of the Blue Ridge are generally vegetated in dense Southern Appalachian spruce-fir forests . The area is host to many animals, including: The largest city located in

7161-624: The range. Trees were unable to survive at the higher elevations and were replaced by tundra vegetation. Spruce-fir forests occupied the valleys and slopes below approximately 4,950 feet (1,510 m). The persistent freezing and thawing during this period created the large blockfields that are often found at the base of large mountain slopes. According to the Köppen climate classification system, Great Smoky Mountains National Park has two climate types: humid subtropical (Cfa), and temperate oceanic (Cfb). The plant hardiness zone at Kuwohi Visitor Center

7254-424: The red spruce fail to encroach into the beech gaps is unknown. The Southern Appalachian spruce–fir forest —also called the "boreal" or "Canadian" forest—is a relict of the ice ages , when mean annual temperatures in the Smokies were too cold to support a hardwood forest. While the rise in temperatures between 12,500 and 6,000 years ago allowed the hardwoods to return, the spruce-fir forest has managed to survive on

7347-877: The red spruces are believed to be 300 years old, and the tallest rise to over 100 feet (30 m). The main difference between the Southern Appalachian spruce–fir forest and the spruce-fir forests in northern latitudes is the dense broad-leaved understory of the former, which are home to catawba rhododendron , mountain ash , pin cherry , thornless blackberry, and hobblebush . The herbaceous and litter layers are poorly lit year-round and are thus dominated by shade-tolerant plants such as ferns, namely mountain wood fern and northern lady fern , and over 280 species of mosses. The Great Smoky Mountains National Park has over 1,400 flowering plant species . Many wildflowers grow in mountains and valleys, including bee balm , Solomon's seal , Dutchman's breeches , various trilliums ,

7440-453: The south-facing North Carolina side of the range. Cove hardwood forests, which are native to southern Appalachia, are among the most diverse forest types in North America. The cove hardwood forests of the Smokies are mostly second-growth, although some 72,000 acres (290 km ) are still old-growth. They are found in the valleys between mountain ridges at elevations below 4,500 feet (1,400 m) in deep moist soil. The Albright Grove along

7533-490: The southern Appalachians and links two national parks: Shenandoah and Great Smoky Mountains . In many places along the parkway, there are metamorphic rocks ( gneiss ) with folded bands of light-and dark-colored minerals, which sometimes look like the folds and swirls in a marble cake. Most of the rocks that form the Blue Ridge Mountains are ancient granitic charnockites , metamorphosed volcanic formations, and sedimentary limestone. Recent studies completed by Richard Tollo,

7626-708: The southwest, Raven Fork near Oconaluftee, Cosby Creek near Cosby , and Roaring Fork near Gatlinburg . More than 100 prominent waterfalls are located within the park. The tallest is Ramsey Cascades, located at the base of Mt. Guyot. This waterfall drops 100 feet (30 m) over rock outcroppings into a small pool below. Rainbow Falls is the tallest single-drop waterfall, plunging 80 feet (24 m) along LeConte Creek. Other popular waterfalls include Grotto Falls, Laurel Falls, Abrams Falls, Mingo Falls, Mouse Creek Falls, and Hen Wallow Falls. The park service maintains four historic districts and one archaeological district within park boundaries, as well as nine individual listings on

7719-408: The spruce-fir and northern hardwood zones. Ovenbirds , whip-poor-wills , and downy woodpeckers live in the drier pine-oak forests and heath balds. Bald eagles and golden eagles have been spotted at all elevations in the park. Peregrine falcon sightings are also not uncommon, and a peregrine falcon eyrie is known to have existed near Alum Cave Bluffs throughout the 1930s. Red-tailed hawks ,

7812-407: The spruce-fir or boreal forest at the very highest elevations. Appalachian balds —patches of land where trees are unexpectedly absent or sparse—are interspersed through the mid-to-upper elevations in the range. Balds include grassy balds and heath balds. Heath balds are covered mostly in shrubbery that is part of the heath family such as rhododendron and mountain laurel. They are primarily found in

7905-508: The tallest mountain in the United States east of the Rocky Mountains . Nestled between the mountains are a number of deep valleys, some of which are known as coves . The largest and most prominent is Cades Cove , a broad, flat plain situated between the main range and some of the foothills. Other major valleys include The Sugarlands , Greenbrier , Ocanaluftee , Cataloochee , Elkmont , Tremont , and Deep Creek. These valleys are among

7998-677: The term "Blue Ridge" is sometimes applied exclusively to the eastern edge or front range of the Appalachian Mountains, the geological definition of the Blue Ridge province extends westward to the Ridge and Valley area, encompassing the Great Smoky Mountains , the Great Balsams , the Roans , the Blacks , and other mountain ranges. In North Carolina, two lower elevation ranges to the east, referred to as foothills , are also often included as "spurs" of

8091-518: The trails with the largest net elevation gain east of the Mississippi River. Hikers may spend a night at the LeConte Lodge, located near the summit, which provides cabins and rooms for rent except during the winter season. Accessible solely by trail, it is the only private lodging available inside the park, and the highest inn in the eastern United States. The Mt. LeConte Shelter is located atop

8184-426: The two states runs northeast to southwest through the center of the park. The Appalachian Trail passes through the center of the park on its route from Georgia to Maine . With 13 million visitors in 2023, the Great Smoky Mountains National Park is the most visited national park in the United States. The park encompasses 522,419 acres (816.28 sq mi; 211,415.47 ha; 2,114.15 km ), making it one of

8277-421: The two, and all of the blooms progress from lower to higher elevations. The reverse is true in autumn, when nearly bare mountaintops covered in rime ice (frozen fog) can be separated from green valleys by very bright and varied leaf colors. The rhododendrons are broadleafs , whose leaves droop in order to shed wet and heavy snows that come through the region during winter. The Great Smoky Mountains National Park

8370-455: The valley, on the west side of the Blue Ridge, at the Treaty of Lancaster in 1744. The Blue Ridge Mountains have stunted oak and oak-hickory forest habitats , which comprise most of the Appalachian slope forests. Flora also includes grass, shrubs, hemlock and mixed-oak pine forests. While the Blue Ridge range includes the highest summits in the eastern United States, the climate is nevertheless too warm to support an alpine zone , and thus

8463-603: Was arguably the most beloved tree of the range's pre-park inhabitants, was killed off by the introduced Chestnut blight in the early-to-mid 20th century. The understories of the cove hardwood forest contain dozens of species of shrubs and vines. Dominant species in the Smokies include the Eastern redbud ( Cercis canadensis ), flowering dogwood ( Cornus florida ), Catawba rhododendron ( Rhododendron catawbiense ), mountain laurel ( Kalmia latifolia ), and smooth hydrangea ( Hydrangea arborescens ). The mean annual temperatures in

8556-540: Was considered the most polluted national park. From 1999 to 2003, the park recorded approximately 150 unhealthy air days, the equivalent of about one month of unhealthy air days per year. In 2013, Colorado State University reported that, with the passing of the United States Clean Air Act in 1970 and the subsequent implementation of the Acid Rain Program , there had been a "significant improvement" to

8649-561: Was the flashpoint for the 2016 Great Smoky Mountains wildfires , and therefore sustained extensive damage, evident still today in clearly visible burn scars. The extreme heat of the fires resulted in accelerated weathering and potential mass wasting of the exposed rock, and therefore access to the summit is no longer permitted for safety reasons. Both the Laurel Falls and Kuwohi trails offer relatively easy, short, paved paths to their respective destinations. The Laurel Falls Trail leads to
