A bluish haze that looks like smoke often covers the Great Smoky Mountains, also called the Smokies or Great Smokies.
These mountains are part of the Appalachian Mountains and lie between Knoxville, Tennessee, and Asheville, North Carolina.
The Appalachian Trail and the Blue Ridge Parkway both wind through these mountains.
Some of the peaks reach 6,000 feet (1,823 m) and higher.
The Great Smokies are best known as the home of the Great Smoky Mountains National Park.
