Mauna Kea
Earth's tallest mountain measured from base to peak/Mountains
Mauna Kea on Hawaii's Big Island rises just 4,207 meters above sea level, but measured from its base on the ocean floor, it towers over 10,000 meters -- making it taller than Everest by that metric. Its summit is one of the best astronomical observation sites on Earth, hosting some of the world's most powerful telescopes.
