Clingman's Dome Observation Tower, Tennessee

At 6,643 feet above sea level, the summit of Clingman’s Dome is the highest peak in the Smoky Mountains, and the highest point of land in Tennessee. The large curving ramp takes visitors another 54 feet higher, and, it seems, a foot or so higher than the viewing platform on top of Mount Mitchell, in North Carolina, which is otherwise considered the tallest mountain east of the Mississippi (6,684 feet, plus a 11 foot or so high platform, versus Clingman’s Dome’s 6,643 feet, plus a 54 foot tower).
