Mauna Kea

The tallest mountain in the world is actually located in the United States. It is actually taller than Mount Everest (more than twice Mt. Everest’s base-to-peak height) when measured from the seafloor. It’s called Mauna Kea and it’s located in Hawaii. While it is only 13,796 feet in altitude above sea level, when measured from the seafloor it is over 32,000 feet high, while Mount Everest is 29,028 feet high.
