The
Great Smoky Mountains are a
mountain range rising along the
Tennessee–
North Carolina border in the southeastern United States. They are a subrange of the
Appalachian Mountains, and form part of the
Blue Ridge Physiographic Province. The range is sometimes called the
Smoky or
Smokey Mountains, and the name is commonly shortened to the
Smokies. The Great Smokies are best known as the home of the
Great Smoky Mountains National Park, which protects most of the range. The park was established in 1934, and, with over 9 million visits per year, it is the most-visited national park in the United States. Along with the Biosphere reserve, the Great Smokies have been designated 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 the natural fog that often hangs over the range and presents as large smoke plumes from a distance. This fog, which is most common in the morning and after rainfall, is the result of warm humid air from the
Gulf of Mexico cooling rapidly in the higher elevations of Southern Appalachia.
