Koko Crater, Volcanic tuff cone in Hawaii Kai, United States
The 1,208-foot volcanic crater forms part of the Honolulu Volcanics series on the island of Oahu, featuring steep walls of consolidated ash.
The United States military constructed bunkers and a railroad track to the summit during World War II, which remained until 1966.
The Hawaiian name Kohelepelepe connects to mythology about Pele, the volcano goddess, and her encounter with Kamapuaa, resulting in the crater formation.
The Koko Crater Trail extends 0.42 miles upward using former railroad tracks, requiring physical preparation for the steep 1,048-step climb.
Radiocarbon dating indicates this tuff cone belongs to the most recent volcanic activity on Oahu, approximately 7,000 years ago.
