The World’s Tallest Mountain from Base to Peak
October 02, 2012
No, it’s not the Mount Everest, but the Mount McKinley (or Denali) in Alaska !
McKinley has a summit elevation of 20,320 feet (6,194 m) above sea level, making it the highest peak in North America. Measured from base to peak, it is the world’s tallest mountain ON LAND. McKinley sits atop a plain with elevations from 300 metres (1,000 ft) to 900 metres (3,000 ft), for a base-to-peak height of 5,300 to 5,900 metres (17,000 to 19,000 ft).
Mount Everest, on the other hand, sits atop the Tibetan Plateau at a much higher base elevation. Base elevations for Everest range from 4,200 m (13,800 ft) on the south side to 5,200 m (17,100 ft) on the Tibetan Plateau, for a base-to-peak height in the range of 3,650 to 4,650 metres (12,000 to 15,300 ft).
But the world’s tallest mountain ON EARTH (Land and Ocean) is the volcano Mauna Kea. Standing 4,205 m (13,796 ft) above sea level, its peak is the highest point in the U.S. state of Hawaii. However, much of the mountain is below sea level; when measured from its oceanic base, the total height difference is 10,200 m (33,500 ft). McKinley’s base-to-peak height is only little more than half that of the 10,200 metres (33,500 ft).
