20 Underwater Wonders of the World:Mauna Kea. Hawaii

Although Mount Everest may be the highest mountain on land, it pales in comparison to Mauna Kea in Hawaii. The peak of Mauna Kea is the highest point above land in Hawaii but much of the dormant volcano actually sits below sea level. Measured from its oceanic base, the tip of Mauna Kea would actually measure 10,100m, much more than the height of Mount Everest and officially the highest mountain in the world! The volcano is estimated to be around one million years old and is without doubt one of the underwater (and overwater) wonders of the world.
