90-547: Cataloochee is the name of several places associated with the Great Smoky Mountains of Western North Carolina . Great Smoky Mountains The Smokies are part of an International Biosphere Reserve . The range is home to an estimated 187,000 acres (76,000 ha) of old-growth forest , constituting the largest such stand east of the Mississippi River . The coves hardwood forests in

180-472: A UNESCO World Heritage Site . The U.S. National Park Service preserves and maintains 78 structures within the national park that were once part of the numerous small Appalachian communities scattered throughout the range's river valleys and coves. The park contains five historic districts and nine individual listings on the National Register of Historic Places . The name "Smoky" comes from

270-452: A topographic map . However, when the key col is far away, or when one wants to calculate the prominence of many peaks at once, software can apply surface network modeling to a digital elevation model to find exact or approximate key cols. Since topographic maps typically show elevation using contour lines , the exact elevation is typically bounded by an upper and lower contour, and not specified exactly. Prominence calculations may use

360-420: A "closer" peak than the encirclement parent (if there is one), which is still "better" than the peak in question. The differences lie in what criteria are used to define "closer" and "better." The (prominence) parent peak of peak A can be found by dividing the island or region in question into territories, by tracing the two hydrographic runoffs, one in each direction, downwards from the key col of every peak that

450-494: A "hierarchy" of peaks going back to the highest point on the island. One such chain in Britain would read: Billinge Hill → Winter Hill → Hail Storm Hill → Boulsworth Hill → Kinder Scout → Cross Fell → Helvellyn → Scafell Pike → Snowdon → Ben Nevis . At each stage in the chain, both height and prominence increase. Line parentage, also called height parentage, is similar to prominence parentage, but it requires

540-424: A cutoff to form a list of peaks ranked by elevation is standard and is the most common use of the concept, it is also possible to use prominence as a mountain measure in itself. This generates lists of peaks ranked by prominence , which are qualitatively different from lists ranked by elevation. Such lists tend to emphasize isolated high peaks, such as range or island high points and stratovolcanoes . One advantage of

630-589: A distance of 17,755 km (11,032 miles), as well as the parent of the South Summit of Mount Everest at a distance of 360 m (1200 feet). The key col may also be close to the subject peak or far from it. The key col for Aconcagua, if sea level is disregarded, is the Bering Strait at a distance of 13,655 km (8,485 miles). The key col for the South Summit of Mount Everest

720-545: A diverse bird population due to the presence of multiple forest types. Species that thrive in southern hardwood forests, such as the red-eyed vireo , wood thrush , wild turkey , northern parula , ruby-throated hummingbird , and tufted titmouse , are found throughout the lower elevations and cove hardwood forests. Species more typical of cooler climates, such as the raven , winter wren , black-capped chickadee , yellow-bellied sapsucker , dark-eyed junco , and Blackburnian , chestnut-sided , and Canada warblers , are found in

810-753: A formation known as the Ocoee Supergroup . The Ocoee Supergroup consists primarily of slightly metamorphosed sandstones , 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

900-494: A given landmass, the highest peak's prominence will be identical to its elevation. An alternative equivalent definition is that the prominence is the height of the peak's summit above the lowest contour line encircling it, but containing no higher summit within it; see Figure 1. The parent peak may be either close or far from the subject peak. The summit of Mount Everest is the parent peak of Aconcagua in Argentina at

990-408: A great deal of information about the peak's position. In general, the analysis of parents and lineages is intimately linked to studying the topology of watersheds . Alteration of the landscape by humans and presence of water features can give rise to issues in the choice of location and height of a summit or col. In Britain, extensive discussion has resulted in a protocol that has been adopted by

SECTION 10

1080-485: A hierarchy which defines some peaks as subpeaks of others. For example, in Figure ;1, the middle peak is a subpeak of the right peak, which is a subpeak of the left peak, which is the highest point on its landmass. In that example, there is no controversy about the hierarchy; in practice, there are different definitions of parent. These different definitions follow. Also known as prominence island parentage , this

1170-418: A highest submerged col of about 40 m, or only 8888 m below the peak of Everest. As a result, Mauna Kea's prominence might be subjectively more impressive than Everest's, and some authorities have called it the tallest mountain from peak to underwater base. Dry prominence is also useful for measuring submerged seamounts . Seamounts have a dry topographic prominence, a topographic isolation , and

1260-460: A mile (1.6 km) above its base. Because of their prominence, the Smokies receive a heavy annual amount of precipitation. Annual precipitation amounts range from 50 to 80 in (1,300 to 2,000 mm), and snowfall in the winter can be heavy, especially on the higher slopes. For comparison, the surrounding terrain has annual precipitation of around 40 to 50 in (1,000 to 1,300 mm). Flash flooding often occurs after heavy rain. In 2004,

1350-484: 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

1440-708: A narrow area along the foothills and can create extensive areas of fallen trees and roof damage, especially around Cades Cove in the Great Smoky Mountains National Park and the Camp Creek community. Strong winds created by mountain waves were a contributing factor with the devastating Gatlinburg fire on November 28, 2016 during the 2016 Great Smoky Mountains wildfires . Damaging winds can also be generated by strong thunderstorms, with tornadoes and strong thunderstorm complexes (also known as mesoscale convective systems ) occasionally affecting

1530-409: A prominence cutoff criterion. The height parent is the closest peak to peak A (along all ridges connected to A) that has a greater height than A, and satisfies some prominence criteria. The disadvantage of this concept is that it goes against the intuition that a parent peak should always be more significant than its child. However it can be used to build an entire lineage for a peak which contains

1620-437: A prominence-ranked list is that it needs no cutoff since a peak with high prominence is automatically an independent peak. It is common to define a peak's parent as a particular peak in the higher terrain connected to the peak by the key col. If there are many higher peaks there are various ways of defining which one is the parent, not necessarily based on geological or geomorphological factors. The "parent" relationship defines

1710-623: A type of beetle in the ladybug family, Coccinellidae , has been introduced in an attempt to control the pests. Visibility 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, Tennessee and Asheville, North Carolina . Environmental threats are

1800-484: Is Aconcagua (6,960 m), in Argentina , and its prominence is 6,138 m. (To further illustrate the rising-sea model of prominence, if sea level rose 56 m, North and South America would be separate continents and Denali would be 6138 m, its current prominence, above sea level. At a slightly lower level, the continents would still be connected and the high point of the combined landmass would be Aconcagua,

1890-417: Is about 100 m (330 feet) distant. A way to visualize prominence is to imagine raising sea level so the parent peak and subject peak are two separate islands. Then lower it until a tiny land bridge forms between the two islands. This land bridge is the key col of the subject peak, and the peak's prominence is its elevation from that key col. Prominence is interesting to many mountaineers because it

1980-439: Is an objective measurement that is strongly correlated with the subjective significance of a summit. Peaks with low prominence are either subsidiary tops of some higher summit or relatively insignificant independent summits. Peaks with high prominence tend to be the highest points around and are likely to have extraordinary views. Only summits with a sufficient degree of prominence are regarded as independent mountains. For example,

2070-443: Is becoming preferred. There are two varieties of topographic prominence: wet prominence and dry prominence. Wet prominence is the standard topographic prominence discussed in this article. Wet prominence assumes that the surface of the earth includes all permanent water, snow, and ice features. Thus, the wet prominence of the highest summit of an ocean island or landmass is always equal to the summit's elevation. Dry prominence, on

2160-406: Is defined as follows. In Figure 2 the key col of peak A is at the meeting place of two closed contours, one encircling A (and no higher peaks) and the other containing at least one higher peak. The encirclement parent of A is the highest peak that is inside this other contour. In terms of the falling-sea model, the two contours together bound an "island", with two pieces connected by an isthmus at

2250-404: Is equal to its wet prominence (4205 m) plus the depth of its highest submerged col (about 5125 m). Totaling 9330 m, this is greater than any mountain apart from Everest. The dry prominence of Aconcagua is equal to its wet prominence (6960 m) plus the depth of the highest submerged col of the Bering Strait (about 40 m), or about 7000 m. It is worth noting Mauna Kea

2340-560: Is equal to its wet prominence plus the depth of its highest submerged col. Because Earth has no higher summit than Mount Everest , Everest's prominence is either undefined or its height from the lowest contour line. In a dry Earth, the lowest contour line would be the deepest hydrologic feature, the Challenger Deep , at 10,924 m depth. Everest's dry prominence would be this depth plus Everest's wet prominence of 8848 m, totaling 19,772 m. The dry prominence of Mauna Kea

2430-410: Is home to diverse species such as coneflower, skunk goldenrod, Rugels ragwort , bloodroot , hydrangea, and several species of grasses and ferns. A unique community is the beech gap, or beech orchard. Beech gaps consist of high mountain gaps that have been monopolized by beech trees. The beech trees are often twisted and contorted by the high winds that occur in these gaps. Why other tree types such as

2520-406: Is more prominent than peak A. The parent is the peak whose territory peak A is in. For hills with low prominence in Britain, a definition of "parent Marilyn " is sometimes used to classify low hills ("Marilyn" being a British term for a hill with a prominence of at least 150 m). This is found by dividing the region of Britain in question into territories, one for each Marilyn . The parent Marilyn

2610-457: Is not used because there is no obvious choice of cutoff. This choice of method might at first seem arbitrary, but it provides every hill with a clear and unambiguous parent peak that is taller and more prominent than the hill itself, while also being connected to it (via ridge lines). The parent of a low hill will also usually be nearby; this becomes less likely as the hill's height and prominence increase. Using prominence parentage, one may produce

2700-590: Is relatively close to its submerged key col in the Pacific Ocean, and the corresponding contour line that surrounds Mauna Kea is a relatively compact area of the ocean floor. Whereas a contour line around Everest that is lower than 9330m from Everest's peak would surround most of the major continents of the Earth. Even just surrounding Afro-Eurasia would run a contour line through the Bering Straight, with

2790-694: Is the Marilyn whose territory the hill's summit is in. If the hill is on an island (in Britain) whose highest point is less than 150 m, it has no parent Marilyn. Prominence parentage is the only definition used in the British Isles because encirclement parentage breaks down when the key col approaches sea level. Using the encirclement definition, the parent of almost any small hill in a low-lying coastal area would be Ben Nevis , an unhelpful and confusing outcome. Meanwhile, "height" parentage (see below)

2880-462: 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 generally smaller than in different locales. Protected fish species include

2970-468: Is the result of frequent temperature inversions developing in the morning, especially during autumn. Strong damaging winds (80 to 100 mph (130 to 160 km/h), or sometimes greater) are observed a few times each year around the Smoky Mountains during the cool season (October through April), as a result of a phenomenon known as mountain waves . These mountain wave winds are strongest in

3060-826: The Maddron Bald Trail (between Gatlinburg and Cosby) is an accessible old-growth forest with some of the oldest and tallest trees in the entire range. Over 130 species of trees are found among the canopies of the cove hardwood forests in the Smokies. The dominant species include yellow birch ( Betula alleghaniensis ), basswood ( Tilia americana ), yellow buckeye ( Aesculus flava ), tulip tree ( Liriodendron tulipifera ; commonly called "tulip poplar"), silverbells ( Halesia carolina ), sugar maple ( Acer saccharum ), cucumber magnolia ( Magnolia acuminata ), shagbark hickory ( Carya ovata ), Carolina hemlock ( Tsuga caroliniana ) and eastern hemlock ( Tsuga canadensis ). The American chestnut ( Castanea dentata ), which

3150-401: The balsam wooly adelgid , which arrived in the Smokies in the early 1960s. Thus, red spruce is now the dominant species in the range's spruce-fir forest. Large stands of dead Fraser firs remain atop Kuwohi and on the northwestern slopes of Old Black. While much of the red spruce stands were logged in the 1910s, the tree is still common throughout the range above 5,500 feet (1,700 m). Some of

3240-483: The black rat snake , and the northern water snake . The 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 31 species. The red-cheeked 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 . Two other species—the southern gray-cheeked salamander and

3330-576: The gray fox ) are found within the Smokies, with red foxes being documented at all elevations. European boar , introduced as game animals in the early 20th century, thrive in southern Appalachia but are considered a nuisance because of 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

3420-546: The smoky madtom and yellowfin madtom , the spotfin chub , and the duskytail darter . The 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 . Air pollution is contributing to increased red spruce tree mortality at higher elevations and oak decline at lower elevations, while invasive hemlock woolly adelgids attack hemlocks, and balsam woolly adelgids attack Fraser firs . Pseudoscymnus tsugae ,

3510-554: The southern Appalachian salamander —occur only in the general region. Other species include the shovelnose salamander , blackbelly salamander , eastern red-spotted newt , and spotted dusky salamander . The hellbender inhabits swift streams. Other amphibians include the American toad and the American bullfrog , wood frog , upland chorus frog , northern green frog , and spring peeper . Fish include trout , lamprey , darter , shiner , bass , and sucker . The brook trout

3600-430: The white-tailed deer , the population of which drastically expanded with the creation of the national park. The bobcat is the only remaining wild cat species, although sightings of cougars , which once thrived in the area, are still occasionally 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. Two species of fox ( red fox and

3690-469: 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 mean annual temperatures and an increase in precipitation throughout

3780-685: The Chimney Tops, and kuwahi ᎫᏩᎯ, or "mulberry place". Most Cherokee settlements were located in the river valleys on the outer fringe of the Smokies, which along with the Unicoi Mountains provided the main bulwark dividing the Overhill Cherokee villages in modern Tennessee from the Cherokee Middle towns in modern North Carolina. The Overhill town of Chilhowee was situated at the confluence of Abrams Creek and

3870-587: The Dragon's Advocate and even hardy orchids . There are two native species of rhododendron in the area. The catawba rhododendron has purple flowers in May and June, while the rosebay rhododendron has longer leaves and white or light pink blooms in June and July. The orange- to sometimes red-flowered and deciduous flame azalea closely follows along with the catawbas. The closely related mountain laurel blooms in between

3960-740: The Little Tennessee, and the Overhill town of Tallassee was located just a few miles upstream near modern Calderwood (both village sites are now under Chilhowee Lake). A string of Overhill villages, including Chota and Tanasi , dotted the Little Tennessee valley north of Chilhowee. Topographic prominence In topography , prominence or relative height (also referred to as autonomous height , and shoulder drop in US English, and drop in British English) measures

4050-617: The Mississippian-period villages at Chilhowee and Citico (Pardo's notary called them by their Muskogean names, "Chalahume" and "Satapo"). By the time the first English explorers arrived in southern Appalachia in the late 17th century, the Cherokee controlled much of the region, and the Great Smoky Mountains lay at the center of their territory. One Cherokee legend tells of a magical lake hidden deep within

4140-471: The Smokies are typically divided into three zones: 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, which are highland meadows covered primarily by thick grasses, and heath balds, which are dense thickets of rhododendron and mountain laurel typically occurring on narrow ridges. Mixed oak-pine forests are found on dry ridges, especially on

4230-954: The Smokies, including the Little Pigeon River , the Oconaluftee River , and Little River . Streams in the Smokies are part of the Tennessee River watershed and are thus entirely west of the Eastern Continental Divide . The largest stream entirely within the park is Abrams Creek , which rises in Cades Cove and empties into the Chilhowee Lake impoundment of the Little Tennessee River near Chilhowee Dam . Other major streams include Hazel Creek and Eagle Creek in

4320-526: The Smoky Mountains. The climate of Kuwohi is hemiboreal ( Köppen Dfb , Trewartha Dcb ). As with much of the southern Blue Ridge , the area qualifies as part of the Appalachian Rainforest . On the other hand, Gatlinburg's climate is four-season subtropical ( Cfa ) under Köppen (oceanic Do under Trewartha ), typical of Tennessee. Most of the rocks in the Great Smoky Mountains consist of Late Precambrian rocks that are part of

4410-466: The U.S., 2000 ft (610 m) of prominence has become an informal threshold that signifies that a peak has major stature. Lists with a high topographic prominence cutoff tend to favor isolated peaks or those that are the highest point of their massif ; a low value, such as the Nuttalls', results in a list with many summits that may be viewed by some as insignificant. While the use of prominence as

4500-408: The child peak. For example, one common use of the concept of parent is to make clear the location of a peak. If we say that Peak A has Mont Blanc for a parent, we would expect to find Peak A somewhere close to Mont Blanc. This is not always the case for the various concepts of parent, and is least likely to be the case for encirclement parentage. Figure 3 shows a schematic range of peaks with

4590-410: The color underlying the minor peaks indicating the encirclement parent. In this case the encirclement parent of M is H whereas an intuitive view might be that L was the parent. Indeed, if col "k" were slightly lower, L would be the true encirclement parent. The encirclement parent is the highest possible parent for a peak; all other definitions indicate a (possibly different) peak on the combined island,

4680-585: The concern of many non-profit environmental stewardship groups, especially The Friends of the Smokies. Formed in 1993, the 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. 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

4770-498: 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 (45 kg) and 300 pounds (140 kg), although some grow to more than 500 pounds (230 kg). Other mammals include

4860-488: The disadvantage in using the encirclement parent. A hill in a low-lying area like the Netherlands will often be a direct child of Mount Everest , with its prominence about the same as its height and its key col placed at or near the foot of the hill, well below, for instance, the 113-meter-high key col of Mont Blanc . When the key col for a peak is close to the peak itself, prominence is easily computed by hand using

4950-475: The encirclement parent.) While it is natural for Aconcagua to be the parent of Denali, since Denali is a major peak, consider the following situation: Peak A is a small hill on the coast of Alaska, with elevation 100 m and key col 50 m. Then the encirclement parent of Peak A is also Aconcagua, even though there will be many peaks closer to Peak A which are much higher and more prominent than Peak A (for example, Denali). This illustrates

5040-579: 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 . 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. The Smokies are home to

5130-648: 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

5220-730: 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 and 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 as well as mounds in Townsend . Most of these villages were part of

5310-471: The harsh mountain tops, typically above 5,500 feet (1,700 m). About 10,600 acres (43 km ) of the spruce-fir forest are old-growth. The spruce-fir forest consists primarily of two conifer species— red spruce ( Picea rubens ) and Fraser fir ( Abies fraseri ). The Fraser firs, which are native to southern Appalachia, once dominated elevations above 6,200 feet (1,900 m) in the Smokies. Most of these firs were killed, however, by an infestation of

5400-440: The height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit . The key col ("saddle") around the peak is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria. The prominence of a peak is the least drop in height necessary in order to get from

5490-492: The high contour (giving in a pessimistic estimate ), the low contour (giving an optimistic estimate), their mean (giving a "midrange" or "rise" prominence ) or an interpolated value (customary in Britain). The choice of method depends largely on the preference of the author and historical precedent. Pessimistic prominence, (and sometimes optimistic prominence) were for many years used in USA and international lists, but mean prominence

5580-629: The higher elevations in the Smokies are cool enough to support forest types more commonly found in the northern United States. The northern hardwood forests constitute the highest broad-leaved forest in the eastern United States. About 28,600 acres (116 km ) are old-growth. In the Smokies, the northern hardwood canopies are dominated by yellow birch ( Betula alleghaniensis ) and American beech ( Fagus grandifolia ). White basswood ( Tilia heterophylla ), mountain maple ( Acer spicatum ) and striped maple ( Acer pensylvanicum ), and yellow buckeye ( Aesculus flava ) are also present. The understory

5670-503: The key col. The encirclement parent is the highest point on this entire island. For example, the encirclement parent of Mont Blanc , the highest peak in the Alps , is Mount Everest . Mont Blanc's key col is a piece of low ground near Lake Onega in northwestern Russia (at 113 m (371 ft) elevation), on the divide between lands draining into the Baltic and Caspian Seas . This is

5760-637: The late 19th century and early 20th century devastated much of the forests of the Smokies, but the National Park Service estimates 187,000 acres (760 km ) of old-growth forest remains, comprising the largest old-growth stand in the Eastern United States. Most of the forest is a mature second-growth hardwood forest. The range's 1,600 species of flowering plants include over 100 species of native trees and 100 species of native shrubs. The Smokies are also home to over 450 species of non-vascular plants and 2,000 species of fungi. The forests of

5850-459: The list, or cutoff . John and Anne Nuttall's The Mountains of England and Wales uses a cutoff of 15 m (about 50 ft), and Alan Dawson's list of Marilyns uses 150 m (about 500 ft). (Dawson's list and the term "Marilyn" are limited to Britain and Ireland). In the contiguous United States, the famous list of " fourteeners " (14,000 foot / 4268 m peaks) uses a cutoff of 300 ft / 91 m (with some exceptions). Also in

5940-435: The main sources of prominence data in Britain and Ireland. Other sources of data commonly ignore human-made alterations, but this convention is not universally agreed upon; for example, some authors discount modern structures but allow ancient ones. Another disagreement concerns mountaintop removal , though for high-prominence peaks (and for low-prominence subpeaks with intact summits), the difference in prominence values for

6030-420: The meeting place of two 113 m (371 ft) contours, one of them encircling Mont Blanc; the other contour encircles Mount Everest. This example demonstrates that the encirclement parent can be very far away from the peak in question when the key col is low. This means that, while simple to define, the encirclement parent often does not satisfy the intuitive requirement that the parent peak should be close to

6120-474: The most common hawk species, have been sighted at all elevations. Owl species include the barred owl , eastern screech owl , and northern saw-whet owl . Timber rattlesnakes —one of two venomous snake species in the Smokies—are found at all elevations. The other venomous snake, the copperhead , is typically found at lower elevations. Other reptiles include the eastern box turtle , the eastern fence lizard ,

6210-469: 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 2,000-year-old ceramics and evidence of primitive agriculture. The increasing reliance upon agriculture during the Mississippian period ( c.  900 –1600 A.D.) lured Native Americans away from

6300-563: The natural fog that often hangs over the range and presents as large smoke plumes from a distance. This fog is caused by the vegetation emitting volatile organic compounds , chemicals that have a high vapor pressure and easily form vapors at normal temperature and pressure. The Great Smoky Mountains stretch from the Pigeon River in the northeast to the Little Tennessee River in the southeast. The northwestern half of

6390-400: The north retreated and mean 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. Heavy logging in

6480-402: The other hand, ignores water, snow, and ice features and assumes that the surface of the earth is defined by the solid bottom of those features. The dry prominence of a summit is equal to its wet prominence unless the summit is the highest point of a landmass or island, or its key col is covered by snow or ice. If its highest surface col is on water, snow, or ice, the dry prominence of that summit

6570-590: The outer reaches of the Foothills to the northwest and in 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

6660-571: The range but inaccessible to humans. Another tells of a captured Shawnee medicine man named Aganunitsi who, in exchange for his freedom, travels to the remote sections of the range in search of the Uktena . The Cherokee called Gregory Bald Tsitsuyi ᏥᏧᏱ, or "rabbit place," and believed the mountain to be the domain of the Great Rabbit. Other Cherokee place names in the Smokies included Duniskwalgunyi ᏚᏂᏍᏆᎫᏂ, or "forked antlers", which refers to

6750-653: The range gives way to a series of elongate ridges known as the "Foothills," the outermost of which include Chilhowee Mountain and English Mountain . The range is roughly bounded on the south by the Tuckasegee River and to the southeast by Soco Creek and Jonathan Creek. The Smokies comprise parts of Blount County , Sevier County , and Cocke County in Tennessee and Swain County and Haywood County in North Carolina. The sources of several rivers are located in

6840-474: The range's highest topographic prominence at 4,503 feet (1,373 m). Mount Le Conte is the tallest (i.e., from immediate base to summit) mountain in the range, rising 5,301 feet (1,616 m) from its base in Gatlinburg to its 6,593-foot (2,010 m) summit. The Smokies rise prominently above the surrounding low terrain. For example, Mount Le Conte (6,593 feet [2,010 m]) rises more than

6930-571: The range's lower elevations are among the most diverse ecosystems in North America, and the Southern Appalachian spruce–fir forest that covers the upper elevations is the largest of its kind. The Smokies are home to the densest black bear population in the Eastern United States and the most diverse salamander population outside of the tropics. Along with the biosphere reserve, the Great Smoky Mountains have been designated

7020-406: 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. Between 16,500 and 12,500 years ago, the glaciers to

7110-424: 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

7200-804: 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. Many wildflowers grow in mountains and valleys, including bee balm , Solomon's seal , Dutchman's breeches , various trilliums ,

7290-404: The remnants of Hurricane Frances caused major flooding, landslides , and high winds, which were soon followed by Hurricane Ivan , making the situation worse. Other post-hurricanes, including Hurricane Hugo in 1989, have caused similar damage in the Smokies. As for temperatures, the average temperature difference between the mountains ( Newfound Gap around 5,000 feet (1,500 m) MSL and

7380-537: The south-facing North Carolina side of the range. Stands dominated by the Eastern hemlock ( Tsuga canadensis ) are occasionally found along streams and broad slopes above 3,500 feet (1,100 m). 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. The Albright Grove along

7470-451: The southwest, Raven Fork near Oconaluftee, Cosby Creek near Cosby , and Roaring Fork near Gatlinburg . The Little Tennessee River passes through five impediments along the range's southwestern boundary, namely Tellico Lake , Chilhowee Lake , Calderwood Lake , Cheoah Lake , and Fontana Lake . The highest point in the Smokies is Kuwohi , the tallest mountain in Tennessee, which rises to an elevation of 6,643 feet (2,025 m). It has

7560-409: The sruce-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 ,

7650-431: The summit to any higher terrain. This can be calculated for a given peak in the following manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the key col (or highest saddle , or linking col , or link ) is defined as the highest of these points, along all connecting paths; the prominence is the difference between the elevation of the peak and the elevation of its key col. On

7740-501: The two conventions is typically relatively small. The key col and parent peak are often close to the sub-peak but this is not always the case, especially when the key col is relatively low. It is only with the advent of computer programs and geographical databases that thorough analysis has become possible . For example, the key col of Denali in Alaska (6,194 m) is a 56 m col near Lake Nicaragua . Denali's encirclement parent

7830-557: 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 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

7920-411: The valleys (Park Headquarters around 1,600 feet (490 m) MSL in the Great Smoky Mountains National Park is between 10 and 13 °F (6 and 7 °C) with highs and between 3 and 6 °F (2 and 3 °C) with lows. The difference between high temperatures is similar to the moist adiabatic lapse rate (3.3 degrees Fahrenheit per 1,000 ft), while the smaller difference between low temperatures

8010-418: The world's second-highest mountain is K2 (height 8,611 m, prominence 4,017 m). While Mount Everest 's South Summit (height 8,749 m, prominence 11 m ) is taller than K2, it is not considered an independent mountain because it is a sub-summit of the main summit (which has a height and prominence of 8,848 m). Many lists of mountains use topographic prominence as a criterion for inclusion in

8100-532: Was arguably the most beloved tree of the range's pre-park inhabitants, was killed off by the introduced Chestnut blight in the 1920s. 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
