As part of the Appalachian mountains, the Great Smoky Mountains, or the Smokies, are one of America’s oldest mountain ranges forming approximately 200-300 million years ago. The Smokies run along the border of Tennesee and North Carolina in the Southeastern United States.

The 522,427 acres of Great Smoky Mountain National Park is relatively untouched and gives an idea of temperate flora before the influence of humans.

Great Smoky Mountains National Park is the most visited of the 59 national parks in the United States. In 2016 the park had 11.6 million recreational visitors while the second most visited, Grand Canyon, had 4.6 million visitors. The park is one of the world’s few International Biosphere Reserves and an UNESCO World Heritage Site.

The name “Smoky” comes from the fog that forms over the mountain range. The fog is caused by the mountain vegetation as the plants emit volatile organic compounds into the atmosphere. A fog begins to form due to the high volume of flora and fauna releasing a high concentration of these compounds. Unlike oxygen, these compounds have a high vapor pressure and easily form vapors at normal temperature and pressure which is why we can see it.

Animals of the Great Smoky Mountains

Black bears

Black bears are typically black in color but may also be brown or cinnamon. Male black bears weigh around 250 pounds while adult females are smaller weighing over 100 pounds. Bears may also double their weight by the fall. Bears over 600 pounds have been documented in Great Smoky Mountains National Park.

Black bears live at all elevations of Great Smoky Mountains National Park. There are an estimated 2,000 black bears at Great Smoky National Park—about two bears per square mile.

Black bears are able to climb trees, swim, and can run 30 mph/ 48 kph. Be sure to practice bear safety while adventuring outdoors.

Salamanders 

The Great Smoky Mountains are known as the “Salamander Capital of the World.” The majority of vertebrate (backboned) animals, including humans, in the park on any given day are salamanders. Be on the look out for salamanders such as the marbled or spotted salamander. Hellbenders are the largest salamander species you’ll encounter in the Smokies.

There is also a species of salamander with red cheeks called the red-cheeked salamander whose entire population is mostly found primarily within Great Smoky Mountain National Park.

  • Black-chinned red salamander is orange, brownish-orange, or bright red with random black spots.
  • Red-cheeked salamander, also a Jordan’s salamander, is a solid gray color with red, orange, or yellow patches on the side of the head.
  • Blackbelly salamander is a dark brown or black with two rows of small pale spots along each side of the back. The belly is usually black but may have pale flecks in young individuals.
  • Jordan’s salamander is a gray color with red, orange, or yellow patches on the side of the head.
  • Blue Ridge two-lined salamander is bright yellow, yellow-orange, or orange. There are two black lines along the back with dots or blotches.
  • Imitator salamander is dark brown or blackish, sometimes with a pale intermittent stripe down its back and a pale line joining eye to jaw. It often has red or orange cheek patches mimicking the red-cheeked salamander.
  • Blue Ridge two-lined salamander is bright yellow, yellow-orange, or orange. There are two black lines along the back with dots or blotches.
  • Slimy salamander is a blackish-blue color with scattered silvery-white or gold spots all over their body.

Lightning Bugs

The Smokies are home to a species of lightning bug, or firefly, called the photinus carolinus. During mating season, this species of firefly will flash a special lightning sequence to attract mates. The flashes will eventually sync up to have a synchronously flashing forest. Each year, Great Smoky Mountain National Park holds a lottery for entry into the park for a chance to see the synchronous lightning bugs. The synchronous lightning typically occurs in June. Learn more about the annual firefly viewing at the Great Smoky Mountains.

Natural Features of the Great Smoky Mountains

Elevations in Great Smoky Mountain National Park range from approximately 875 feet at the mouth of Abrams Creek to 6,643 feet at Clingmans Dome. Sixteen mountains peaks exceed 6,000 feet in elevation.

Clingmans Dome, Mount Guyot, and Mount Le Conte are the thre highest peaks.

Most of the rocks in Great Smoky Mountains National Park are sedimentary and were formed by accumulations of clay, silt, sand, gravel, and minor amounts of calcium carbonate in flat-lying layers.

In the Smokies high country, over 85″ of rain falls on average each year. During wet years, peaks like Mt. Le Conte and Clingmans Dome receive over eight feet of rain. There are 730 miles of fish-bearing streams and another 1,300 miles of tributaries.
