''' ]] The Great Smoky Mountains are a major Mountain Range in the southern part of the Appalachian Mountains , the second ridge line forming a north-south running Mountain Chain from the Eastern United States and bordering the western side of the Blue Ridge Mountains . Also called the '''Smoky Mountains''' or the '''Smokies''', they straddle the border between Tennessee and North Carolina , and are entirely west of the Eastern Continental Divide . The , Pisgah National Forest , and Cherokee National Forest outside of the park. The name of the area comes from the natural Haze that often hangs over it. As in the neighboring Blue Ridge Mountains to the east, Hydrocarbon s produced by Tree s and other local Vegetation —as well as higher Humidity —produce a bluish cast to the Sky , even over short distances. Visibility now is dramatically reduced by Smog from both the Southeastern United States and the Midwest , and smog Forecast s are prepared daily by the Environmental Protection Agency for both nearby Knoxville, Tennessee , and Asheville, North Carolina . PEAKS The highest point in the Smokies is Clingmans Dome (6,643 feet or 2,025 m), which is located within the national park. A paved road leads to within 300 vertical feet (90 m) of the summit, and from there visitors can walk a paved trail to the top. A handicap-accessible tower is located at the summit, and on clear days visitors can see five states (Tennessee, North Carolina, South Carolina , Georgia , and Kentucky ). Clingmans Dome is also the highest point in Tennessee. The Smokies rise prominently above the surrounding low terrain. For example, Mount LeConte (6,593 feet or 2,010 m) rises more than a mile (1.6 km) above its base. Because of their prominence, the Smokies receive heavy annual amounts of precipitation. Annual precipitation amounts range from 50 to 80 inches (130-200 cm) {Link without Title} , 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 inches (100-130 cm). Other prominent peaks include: ]]
FLORA AND FAUNA Biological diversity is the hallmark of Great Smoky Mountains. Over 10,000 species have been documented; scientists believe an additional 90,000 species may be present {Link without Title} . Many Wildflower s grow in the mountains and valleys, including Bee Balm , Solomon's Seal , Dutchman's Breeches , various Trillium s, the Dragon's Advocate and even hardy Orchid s. The ecosystem is not as healthy as it could be. Atmospheric pollution may be contributing to increased Red Spruce tree mortality at higher elevations and oak decline at lower elevations, while the Invasive Hemlock Woolly Adelgid attacks the Hemlock s, and the Balsam Woolly Adelgid attacks the Fir s. Pseudoscymnus Tsugae has been introduced in an attempt to control the pests {Link without Title} . Other subalpine species more typical of Maine and Canada are found at the highest elevations, above about 5,000 feet (1,500 m) AMSL . Some Bird Migration actually takes place vertically, with the "local" birds going up and down the mountains rather than north and south. 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 blooms white or a light pink 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 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 Valley s by very bright and varied leaf colors. The rhododendrons are Broadleaf s, whose leaves droop in order to shed wet and heavy Snow s that come through the region in winter. WATER Several rivers rise from streams in the Smokies, including the Pigeon River , Little Pigeon River , Oconaluftee River , Nantahala River . The French Broad River originates in the Blue Ridge Mountains and flows through Asheville, North Carolina , and across the northeastern end of the Smokies. A Norfolk Southern railway line runs along the river as well. Flooding can and does occur after heavy Rain s. In 2004, the remnants of Hurricane Frances caused major flooding, Landslide s, and high Wind s, which was soon followed by Hurricane Ivan , making the situation worse. Other post- Hurricane s, including Hurricane Hugo in 1989, have caused similar damage in the Smokies. CULTURE AND TOURISM The Culture of the area is that of Southern Appalachia , and previously the Cherokee people. Tourism is a huge draw to the area, particularly to Pigeon Forge and Gatlinburg in Tennessee, Cherokee, North Carolina . Rafting , either leisurely River Tubing or in full Whitewater , is common all Summer . Downhill Skiing is also done in Winter , though for a short season, at places like Cataloochee and Ober Gatlinburg . Country Music legend Dolly Parton is from the Smokies, born and raised in Sevierville . She is associated with the Dollywood Amusement Park . SEE ALSO
