History of Clingmans Dome
The Clingmans Dome area is steeped in rich history. Clingmans Dome was an important place for the Cherokee people who inhabited the mountains. The Cherokee people have called the Smokies home for hundreds of years, dating back to before the arrival of Christopher Columbus. They believed the highest point in the mountains was home to the “White Bear,” or the chief of all bears. Clingmans Dome was given to the federal government by North Caroline in 1789. Clingmans Dome became part of Tennessee when it became a state in 1796.

History Behind the Name
Clingmans Dome has had many names. The Cherokee people who originally inhabited the Great Smoky Mountains called this high point Kuwa'hi, which means “mulberry place.” As time progressed and settlers started moving to the Great Smoky Mountains, the area became known as “Smoky Dome.” The name of the peak was changed to Clingmans Dome in 1859 after Civil War Confederate general Thomas Lanier Clingman.

Observation Tower History
Modern history of the dome is just as interesting. The observation tower that provides breathtaking views today was part of the National Parks Service’s Mission 66 program, which modernized the parks to meet visitor demand. The tower has local roots. It was designed by architect Hubery Benn of Gatlinburg and built by W.C. Norris of Waynesville, NC. Ground was broken in 1958, but there were several construction delays as Clingmans Dome weather can be quite volatile.

Clingmans Dome Geology
Observation tower and Clingmans Dome parking lot opened to the public on Oct. 23, 1959. The tower cost a mere $57,000 to construct, which is about $510,000 in today’s money. Clingmans Dome is part of the Copperhill Formation, part of the Ocoee Supergroup. The mountains are made of metasedimentary rocks and were formed 560 million years ago. Today, geologists estimate that the Great Smoky Mountains erode and shrink about 2 inches every thousand years.
