Prehistory
Native Americans have likely been hunting in the Great Smoky Mountains for 14,000 years. Numerous Archaic period (c. 8000–1000 B.C.) artifacts have been found within the national park’s boundaries, including projectile points uncovered along likely animal migration paths. Woodland period (c. 1000 B.C. – 1000 A.D.) sites found within the park contained 2000+-year- old ceramics and evidence of primitive agriculture.
The increasing reliance upon agriculture during the Missossippian period (c. 900–1600 A.D.) lured Native Americans away from the game-rich forests of the Smokies and into the fertile river valleys on the outer fringe of the range. Substantial Mississippian-period villages were uncovered at Citico, Toqua, named after the Cherokee villages that later thrived at these sites along the Little Tennessee River in the 1960s. Fortified Mississippian-period villages have been excavated at the McMahan Indian Mounds in Sevierville and more recently in Townsend.
Most of these villages were part of a minor chiefdom centered on a large village known as Chiaha, which was located on an island now submerged by Douglas Lake. The 1540 expedition of Hernando de Soto and the 1567 expedition of Juan Pardo passed through the French Broad River valley north of the Smokies, both spending a considerable amount of time at Chiaha. The Pardo expedition followed a trail across the flanks of Chilhowee Mountain to the Mississippian-period villages at Chilhowee and Citico, Pardo’s notary called them by their Muskogean names, “Chalahume” and “Satapo”).
History
Geology
Most of the rocks in the Great Smoky Mountains consist of late Precambrain rocks that are part of a formation known as the Ocoee Supergroup. The Ocoee Supergroup consists primarily of slightly metamorphosed sandstone, phyllites, schists and slate. Early Precambrian rocks, which include the oldest rocks in the Smokies, comprise the dominant rock type in the Raven Fork Valley in the Oconaluftee valley, and lower Tuckasegee River between Cherokee and Bryson City. They consist primarily of metamorphic gneiss, granite, and schist. Cambrian sedimentary rocks are found among the outer reaches of the Foothills to the northwest and limestone coves such as Cades Cove.
The Precambrian gneiss and schists, the oldest rocks in the Smokies— formed over a billion years ago from the accumulation of marine sediments and igneous rock in a primordial ocean. In the Late Precambrian period, this ocean expanded, and the more recent Ocoee Supergroup rocks formed from accumulations of the eroding land mass onto the ocean’s continental shelf.
By the end of the Paleozoic era, the ancient ocean had deposited a thick layer of marine sediments which left behind sedimentary rocks such as limestone. During the Ordovician period, the North American and African plates collided, destroying the ancient ocean and initiating the Alleghenian orogeny —the mountain-building epoch that created the Appalachian range. The Mesozoic era saw the rapid erosion of the softer sedimentary rocks from the new mountains, re-exposing the older Ocoee Supergroup formations.
Around 20,000 years ago, subarctic glaciers advanced southward across North America, and although they never reached the Smokies, the advancing glaciers led to
colder annual temperatures and an increase in precipitation throughout 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. The persistent freezing and thawing during this period created the large blockfields that are often found at the base of large mountain slopes.
Between 16,500 and 12,500 years ago, the glaciers to the north retreated and annual temperatures rose. The tundra vegetation disappeared, and the spruce-fir forests retreated to the highest elevations. Hardwood trees moved into the region from the coastal plains, replacing the spruce-fir forests in the lower elevations. The temperatures continued warming until around 6,000 years ago, when they began to gradually grow cooler.

Threatened Ecosystem
Air pollution is contributing to increased Red Spruce tree mortality at higher elevations and oak decline at lower elevations, while invasive hemlock wooly adelgids attack Hemlocks and balsam woolly adelgids attack Fraser firs. Pseudoscymnus tsugae, a type of beetle in the ladybug family, Coccinellidae, has been introduced in an attempt to control the pests.
Visibility now is dramatically reduced by smog from both the Southeastern United States and the Midwest, and smog forecasts are prepared daily by the Environmental Protection Agency for both nearby Knoxville TN, and Asheville, North Carolina.
Environmental threats are the concern of many non-profit environmental stewardship groups, especially The Friends of the Smokies. Formed in 1993, the friends group assists the National Park Service in its mission to preserve and protect the Great Smoky Mountains National Park by raising funds and public awareness, and providing volunteers for needed projects.
The park was chartered by the United States Congress in 1934, and officially dedicated by President Franklin D. Roosevelt in 1940. The Great Smoky Mountains was the first national park having land and other costs paid in part with federal funds; previous parks were funded wholly with state money or private funds. The park was designated as a UNESCO World Heritage Site in 1983, and an International Biosphere Reserve in 1988.
Wilson B. Townsend, the head of Little River Lumber, began advertising Elkmont as a tourist destination in 1909. Within a few years, the Woodland Hotel and the Appalachian Club had been established to cater to elite Knoxvillians seeking summer mountain getaways. In the early 1920s, several Appalachian Club members, among them Knoxville businessman Colonel David Chapman, began seriously considering a movement to establish a national park in the Great Smokies. As head of the Great Smoky Mountains Park Commission, Chapman was largely responsible for raising funds for land purchases and coordinating park efforts between local, state, and federal entities.
For thousands of years, this region was occupied by successive cultures of indigenous peoples. The historical Cherokee had their homeland here, and occupied numerous towns in the river valleys on both sides of the Appalachian Mountains. Their first encounters with Europeans were as traders, mostly coming from the colonial Carolinas and Virginia. European Americans did not begin to settle here until the late 18th and early 19th centuries. Particularly because of their pressure to acquire land in the Deep South, in 1830 President Andrew Jackson signed the Indain Removal Act, beginning the process that eventually resulted in the forced removal of all Indian tribes east of the Mississippi River to Indian Territory, now Oklahoma.


The Great Smoky Mountains are home to 66 species of mammals, over 240 species of birds, 43 species of amphibians, 60 species of fish, and 40 species of reptiles. The range has the densest black bear population east of the Mississippi River. The black bear has come to symbolize wildlife in the Smokies, and the animal frequently appears on the covers of the Great Smoky Mountains National Park’s literature. Most of the range’s adult eastern black bears weigh between 100 pounds to 300 pounds, although some grow to more than 500 pounds.
The elk are part of a herd which was transplanted to Cataloochee in 2001, in an attempt to reintroduce the species to the Appalachians in North Carolina, other mammals in the Great Smokies include the white tailed deer, the population of which drastically expanded with the creation of the national park. The bobcat is the range’s only remaining wild cat species, although sightings of cougars, which once thrived in the area, are still reported. The coyote is not believed to be native to the range, but has moved into the area in recent years and is treated as a native species. Wolf packs do not roam this region due to extirpation. They modernly reside in Alaska, portions of the Great Lakes region, all northwestern American states and Canada. Two species of fox, red fox and the gray fox are found within the Smokies, with red foxes being
European boar, introduced as game animals in the early 20th century, thrive in Southern Appalachia but are considered a nuisance due to their tendency to root up and destroy plants. The boars are seen as taking food resources away from bears as well, and 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 over two dozen species of rodents, including the endangered northern flying squirrel, and 10 species of bats, including the endangered Indiana bat. The National Park Service has successfully reintroduced river otters and elk into the Great Smoky Mountains National Park. An attempt to reintroduce the red wolf in the early 1990s ultimately failed. These wolves were removed from the park and relocated to the Alligator River National Wildlife Refuge in North Carolina.
Brook trout are native to the Great Smoky Mountains, the Smokies are home to a diverse bird population due to the presence of multiple forest types. Species that thrive in southern hardwood forests, such as the redeyed vireo, wood thrush, wild turkey, northern parula, ruby throated hummingbird, tufted titmouse, are found throughout the range’s lower elevations and cove hardwood forests. Species more typical of cooler climates, such as the raven, winter wren, black capped chickadee, yellow bellied sapsucker, darkeyed junco, Blackburnian, chestnut sided, and Canada Wablers, are found in the range’s spruce-fir and northern hardwood zones.
Ovenbirds, whip-poor-wills, downy woodpeckers live in the drier pine-oak forests and heath balds. Bald eagles, 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, the most common hawk species, have been sighted at all elevations in the range. Owl species residing in the Smokies include the barred owl, eastern screech owl, and northern saw whet owl.
The Great Smokies are home to one of the world’s most diverse salamander populations. Five of the world’s nine families of salamanders are found in the range, consisting of up to thirty-one species. A type of Jordan?s salamander known as the redcheeked salamander is found only in the Smokies. The imitator salamander is found only in the Smokies and the nearby Plott Balsams and Great Balsam Mountains.
Fish inhabiting the streams of the Smokies include trout, lamprey, darter, shier, bass, and sucker. The brook trout is the only trout species native to the range, although northwestern rainbow trout and European brown trout were introduced in the first half of the 20th century. The larger rainbow and brown trout outcompete the native brook trout for food and habitat at lower elevations. As such, most of the brook trout found in the park today are in streams above 3,000 feet in elevation. Trout in the Smokies are generally smaller than other members of their species in different locales. Protected fish species in the range include the smoky and yellowfin madtom, the spotfin chub, and the duskytail darter.
The lightning bug firefly Photinus carolinus, whose synchronized flashing light displays occur in mid-June, is native to the Smoky Mountains with a population epicenter near Elkmont, Tennessee.
