Mountain
Heights of mountains are typically measured above sea level. Using this metric, Mount Everest is the highest mountain on Earth, at . There are at least 100 mountains with heights of over above sea level, all of which are located in central and southern Asia. The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Denali, Mount Kilimanjaro and Nanga Parbat are possible candidates for the tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea ( above sea level) is the world's tallest mountain and volcano, rising about from the Pacific Ocean floor.
Mount Harvard
In 1962, three Harvard men attempted to erect a fourteen-foot metal pole on the top of Harvard, with a sign that read "Mt. Harvard, 14,434. This sign erected at an altitude of 14,434 making it the second highest point in the contiguous United States." Before they could reach the top of the mountain darkness set in, and the group was forced to abandon the pole a few hundred yards short of the summit. The next year, two Harvard men (Tim Wirth, who later represented Colorado's Second Congressional District and then served a term in the U.S. Senate, and his brother John), along with a Cornell graduate carried the pole the extra distance, and completed the task. The pole sat on the mountain for roughly twenty years, until it disappeared at some time in the 1980s, most likely as part of an effort to clean up Colorado's fourteeners.
