Charlies Bunion
Charlies Bunion is a mountain in the Great Smoky Mountains of the Southeastern United States, characterized by a large boulder-like protrusion just below the summit on its otherwise-sheer northern face. The mountain is a rare instance of a bare-rock summit in the Smokies.
Charlies Bunion rises to an elevation of 5,565 feet (1,696 m) above sea level, and is situated along the state line between Sevier County, Tennessee and Swain County, North Carolina. The Appalachian Trail crosses the mountain's northern slope some four miles (6 km) east of Newfound Gap, allowing easy access to dayhikers and rock climbers.
==Geology==
Charlies Bunion comprises the western wing of The Sawteeth, a series of narrow, jagged cliffs connecting the high peaks of the Central Smokies with the high peaks of the Eastern Smokies. These cliffs are underlain by a Precambrian metamorphic rock of the Ocoee Supergroup known as "Anakeesta Formation," which consists mainly of slate.〔Harry Moore, ''A Roadside Guide to the Geology of the Great Smoky Mountains National Park'' (Knoxville: University of Tennessee Press, 1988), 11.〕 The Anakeesta Formation, which comprises much of the crest of the Central Smokies, was created nearly a billion years ago from ancient ocean sediments. The rock was thrust upward during the Appalachian orogeny, when the North American and African plates collided around 400 million years ago.〔''Ibid''., 23-27.〕
The steep northern face of Charlies Bunion is drained by the headwaters of the Middle Fork of the Little Pigeon River, and loses 2,000 feet (609 m) in elevation in just over a mile. The southern face, which is more gradual, is drained by the headwaters of the Oconaluftee River, specifically Kephart Prong and Bradley Fork.
