Thunderhead Mountain is a mountain in the west-central part of the Great Smoky Mountains, located in the Southeastern United States. Rising along the border between Tennessee and North Carolina, the mountain dominates the Western Smokies. The Appalachian Trail crosses its summit, making it a popular hiking destination. Rocky Top, a knob on the western part of the mountain's summit ridge, shares its name with a popular Tennessee state song. Thunderhead rises approximately above its northern base at Little River and approximately above its southern base at Bone Valley. The mountain consists of three peaks, the lowest being Rocky Top at above sea level and the easternmost being the highest at above sea level. Thunderhead is the highest point in Blount County, Tennessee and the highest point on the Appalachian Trail coming from the south until the trail ascends Silers Bald some to the east. The mountain's name originated in the 19th century. It probably referred to the unpredictable weather that often strikes the higher elevations in the Smokies. According to Laura Thornborough, a writer who hiked to the summit of Thunderhead along with local guide Sam Cook in the 1930s:
Geology
Thunderhead consists of precambrian sandstone. Thunderhead sandstone is part of the Ocoee Supergroup, which was formed from ancient ocean sediments between 500 million and one billion years ago. The mountain itself was formed appx. 200 million years ago during the Appalachian orogeny, when the collision of the North American and African plates thrust the rock upward.
History
James Spence, who cleared the ridge to the west, was the first known permanent settler in the vicinity. While the extent of Spence's farm is unknown, cattle-grazing had rendered Thunderhead a grassy bald by the late-19th century. Thunderhead is one of the few mountains listed under its current name in Arnold Guyot's 1859 survey of the crest of the Smokies. Guyot measured Thunderhead's elevation at above sea level, missing the modern measurement by just seven feet. During the Civil War, a group of East Tennesseans attempted to form a wilderness settlement on the mountain's north slope known as "New World," although the settlement didn't last. The settlement was located along Thunderhead Prong, near Chimney Rocks. As preservationist groups began buying land in the Smokies in the early 1900s, Thunderhead became a favorite hiking destination for park visitors. John W. Oliver, the great-grandson of the first European settlers in Cades Cove, started offering guided hikes to the mountain in 1924. The trail he used largely followed the Bote Mountain Trail-Appalachian Trail route still in use today. In the years after the Great Smoky Mountains National Park was formed, wooded plants started to reclaim much of the Smokies crest west of Clingmans Dome. Park strategy at present is to allow Thunderhead to return to its natural state. A narrow path is maintained across the top of the mountain for Appalachian Trail thru-hikers.
Access
The Bote Mountain Trail, with its trailhead on Little River Road, ascends to the crest of the Smokies and intersects the Appalachian Trail at Spence Field. From Spence Field, it is approximately to the summit of Thunderhead. The Lead Cove Trail, also beginning on Little River Road, offers the shortest access to the summit by bypassing the first of the Bote Mountain Trail. From the Lead Cove trailhead, it is approximately to the summit of Thunderhead. The Anthony Creek Trail, rising out of the Cades Cove campground, also bypasses the first of the Bote Mountain Trail. From the Anthony Creek trailhead, it is approximately to the summit of Thunderhead. While the main summit of Thunderhead is covered in foliage, Rocky Top offers a 360-degree view of the western Smokies.
