Question: what is the highest mountain peak in hawaii

title: Mauna Kea
text: Mauna Kea ( / ˌmɔːnə ˈkeɪ. ə / or / ˌmaʊnə ˈkeɪ. ə / , Hawaiian : ( ˈmɐwnə ˈkɛjə ) ) , is a dormant volcano on the island of Hawaii . Standing 4,207 m ( 13,802 ft ) above sea level , its peak is the highest point in the state of Hawaii . Much of the mountain is under water ; when measured from its oceanic base , Mauna Kea is over 10,000 m ( 33,000 ft ) tall and is the tallest mountain on Earth . Mauna Kea is about a million years old , and has thus passed the most active shield stage of life hundreds of thousands of years ago . In its current post-shield state , its lava is more viscous , resulting in a steeper profile . Late volcanism has also given it a much rougher appearance than its neighboring volcanoes ; contributing factors include the construction of cinder cones , the decentralization of its rift zones , the glaciation on its peak , and the weathering effects of the prevailing trade winds . Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant . 

Answer: answer: Mauna Kea is the highest mountain peak in the state of Hawaii .
