Mount Everest Is Not The Highest ?

Mauna Kea is a dormant volcano in the Hawaiian Islands, one of five volcanoes which together form the island of Hawaii. Puu Wekiu, one of numerous cinder cones on the summit plateau, is the highest point in the state of Hawaii at 13,796 ft (4,205 m). Mauna Kea is the tallest mountain in the world when measured from base to summit, since its base is located on the seafloor some 20,000 ft (6,000 m) beneath the surface of the Pacific Ocean, bringing its total height to well over 33,000 ft (10,000 m). In the Hawaiian language, mauna kea means "white mountain", a reference to its summit being regularly snow-capped during the Northern Hemisphere winter.
