The boars are seen as taking food resources away from bears as well, and

6860-419: The park include the American toad and the American bullfrog , wood frog , upland chorus frog , northern green frog , and spring peeper . Reptiles found within the park include eight species of turtles , nine species of lizards , and 23 species of snakes . 21 of these snake species are from the family Colubridae , and include multiple kingsnakes , the black rat snake , the northern water snake , and

6958-400: The park include the eastern fence lizard , green anole , and multiple species of skinks . The rarest lizard in the park is the eastern slender glass lizard , a legless lizard often mistaken for a snake. Fish include trout , lamprey , darter , shiner , bass , minnows , and sucker . An estimated 1,073 miles (1,727 km) of streams in the park support fish. The brook trout is

7056-428: 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

7154-418: 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

7252-571: The planning of a six-gate expansion to the terminal, with a target completion date of 2028, to meet the growing needs of the region. In January 2024, airport officials announced they would be closing part of the airport's long-term parking lot to begin a project that would expand the current garage to six stories and add 3,500 parking spots.

7350-632: The proximity of dams along the Little Tennessee River which were a hydroelectric energy source for the production of aluminum. In 1951, the United States Air Force built several facilities on the field and 7,500-foot (2,300 m) runway 5L. The Federal Aviation Administration (FAA) added an Instrument landing system to runways 5L and 23R in 1959. In 1961, with financing by the Tennessee Air National Guard, runway 5L

7448-415: 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

7546-624: 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

7644-439: The rebuilt 10,000-foot runway 5L/23R reopened. McGhee Tyson Airport covers 2,250 acres (9.1 km) at an elevation of 986 feet (301 m). It has two parallel runways: 5L/23R is 10,000 by 150 feet (3,048 x 46 m) concrete and 5R/23L is 9,000 by 150 feet (2,743 x 46 m) asphalt. The fixed-base operator (FBO) at TYS is Signature Aviation , the parent company of Signature Flight Support. In July 2022 Signature Aviation announced

7742-424: 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

7840-877: 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 ,

7938-433: The sole supplier of aviation fuel for commercial, corporate and general aviation aircraft as well as leased hangar space at the airport. In 2023, the airport had 104,459 aircraft operations, averaging 286 per day: 46,858 general aviation , 18,433 air taxi , 9,952 military, and 29,216 air carrier. In 2023, 186 aircraft were based at the airport: 84 single-engine, 26 multi-engine, 50 jet, 22 military, and 4 helicopter . TYS

8036-453: 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

8134-708: 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

8232-408: 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 ,

8330-407: 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

8428-508: The surrounding city area. Larger and better equipped FBOs may additionally offer food vending and restaurant facilities, ground transportation arrangements by taxi/limousine, shuttle van, flight planning and weather information areas (computer- or telephone-based), rest lounges and showers, aviation supplies shop (selling navigation charts , manuals, or in-flight comfort items), access to in-flight catering, and accommodations reservations or concierge services for both crew and passengers through

8526-508: 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

8624-586: The term fixed-base operator originated in the United States, the term has become more common in the international aviation industry as business and corporate aviation has grown. The term has not been officially defined as an international standard, but there have been recent uses of the term in International Civil Aviation Organization (ICAO) publications such as Implementing the Global Aviation Safety Roadmap . After

8722-490: The townsfolk and charging whatever the local economic conditions would allow. As a result, mechanics and early flight instructors moved around with the aircraft and had no established business in any location. With passage of the Air Commerce Act of 1926 and its resulting requirements for the licensing of pilots, aircraft maintenance requirements, and regulations in training standards, the transient nature of civil aviation

8820-458: 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

8918-426: 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

9016-421: 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

9114-603: 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

9212-539: Was built on 60 acres (24 ha) in West Knoxville where West High School is now located. In 1935, the city purchased 351 acres (142 ha) in Blount County for the current airport. On July 29, 1937, an American Airlines Stinson Trimotor (about 10 seats) touched down, the first airline flight; before that, American's Stinsons landed at Island Airport on Dickinson Island east of town. The 1938 directory shows

9310-540: 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

9408-418: Was curtailed. The pilots and mechanics who made their living on the road began establishing permanent businesses at the growing number of airports appearing throughout the United States. These were termed fixed-base operations to distinguish them from the transient businesses that had been common prior to 1926. Fixed-base operators support a wide range of aeronautical activities which may include one or more of

9506-458: Was extended to 9,000 feet (2,700 m). The first scheduled airline jets were Delta DC-9s in December 1965. In 1968, McGhee Tyson built a new air cargo facility; a new passenger terminal opened in 1974, a few years after runway 18/36 closed. Four years later, the Metropolitan Knoxville Airport Authority (MKAA) was established. In 1990, runway 5R/23L was rebuilt to 9,000 feet (2,700 m). In 1992,

9604-561: 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
