Mauna Kea

Mauna Kea is a dormant volcano on the island of Hawaiʻi. It is the highest peak in the state of Hawaiʻi, rising to 13,803 feet (4,207 meters) above sea level. However, a significant portion of the mountain lies submerged beneath the Pacific Ocean. Measured from its base on the ocean floor, Mauna Kea is actually taller than Mount Everest, making it the tallest mountain in the world from base to summit.

The summit of Mauna Kea is one of the best locations in the world for astronomical observation due to its high altitude, dry atmosphere, and minimal light pollution. Consequently, it is home to the Mauna Kea Observatories, a collection of thirteen telescopes operated by astronomers from several countries.

The name "Mauna Kea" means "white mountain" in the Hawaiian language, referring to the snow that often covers its summit during winter. The mountain holds significant cultural and religious importance to Native Hawaiians, who consider it to be sacred. Access to the summit for activities beyond astronomy is a topic of ongoing debate and concern.
