Mount Guyot (Great Smoky Mountains)

Mount Guyot is composed of Precambrian rocks of the Ocoee Supergroup, formed from ocean sediments approximately one billion years ago. The mountain is underlain by Thunderhead sandstone, which is common throughout the Smokies. The Thunderhead sandstone was thrust over Roaring Fork sandstone several hundred million years ago. Mt. Guyot itself was formed during the Appalachian orogeny over 200 million years ago, when the North American and African plates collided, thrusting the rock upward. == Climate ==

Mount Guyot was named in honor of Swiss geographer Arnold Guyot by Guyot's friend, Samuel Buckley. Buckley was a naturalist who accompanied Thomas Lanier Clingman on a survey expedition to the crest of the Smokies in 1858. While Buckley's measurements were often wildly inaccurate, Guyot conducted an expedition the following year, recording more accurate elevations and giving preliminary names to various peaks along the crest. Guyot measured the elevation of Mt. Guyot at , missing the modern measurement by just . Regarding the Eastern Smokies, surveyors and authors alike agreed on one thing: the region was very remote and isolated. Guyot said of the area, "neither the white man or the Indian hunter venture in this wilderness." For Horace Kephart, who wrote extensively on the Smoky Mountains in the early 1900s, Mt. Guyot was the climax of a dense, virtually-insurmountable wilderness: {{blockquote Kephart goes on to relate the account of James Ferris and his wife, two naturalists who bushwhacked their way across the crest of the Smokies to Mt. Guyot in 1900. According to Mrs. Ferris: {{blockquote Mt. Guyot remained isolated until the Civilian Conservation Corps constructed a segment of the Appalachian Trail across the mountain's western slope in 1935. Although the trail opened up the heart of the Eastern Smokies to backpackers, access remained relatively difficult. According to author Laura Thornborough, who climbed Guyot in the late 1930s: {{blockquote Thornborough followed the route out of Greenbrier that ascends Guyot's western slope. She recalls that "there was no trail to Guyot, not even a dim one, but our guides knew the way." The party followed Ramsay Prong until it became "a mere trickle of water," and emerged near modern-day Guyot Spring. From the state line, they found a "dim trail" leading to the summit. Thornborough concludes her report by saying, "if it is wilderness you want, then go to Guyot." == Access ==

The Appalachian Trail and the Balsam Mountain Trail intersect just south of Guyot at Tricorner Knob. They are the only maintained trails to traverse the mountain. From the Cosby Campground (specifically behind Campsite B51), the Snake Den Ridge Trail winds to its intersection with the Appalachian Trail at Inadu Knob. From this intersection, it is approximately to Guyot Spring, on Mt. Guyot's west slope. A section of the Appalachian Trail stretches from Newfound Gap to Tricorner Knob, near Guyot's south slope. The Appalachian-Balsam Trail intersection is approximately from Balsam Mountain Road, a gravel road that begins near Cherokee, North Carolina. While Guyot's eastern slope is very steep, its western slope, known as Guyot Spur, descends gradually for nearly five miles to the Little Pigeon River. A well-known bushwhack follows the creek on the north side of Guyot Spur, starting at Ramsay Cascades and emerging on the Appalachian Trail near Guyot Spring (probably the same path Thornborough's guides followed in the 1930s). This route is approximately eight miles from the Ramsay Cascades Trail parking area, four miles (6 km) of which are maintained trail. While the summit is less than a half-mile from the Appalachian Trail, the thick forest makes any bushwhack a challenge. A faint manway rises from Guyot Spring to the northern summit, although the manway is heavily overgrown. Dead Fraser fir blowdowns and low visibility complicate navigation from any direction. The Appalachian Trail also passes by another Mount Guyot in New Hampshire approximately 1600 miles to the north. ==References==
