Mauna Kea is a dormant volcano on Hawaiʻi Island, standing as the state's highest point at 13,803 feet (4,207 m) above sea level, or over 33,500 feet (10,211 m) from its deep-ocean base, making it the world's tallest mountain. It is a critical, sacred site for Native Hawaiian culture, housing 13 top-tier international astronomical observatories due to its exceptional viewing conditions.
