Geology

Koko Crater is a part of the Honolulu Volcanics, which were craters that formed as vents of the Koʻolau Volcano during its rejuvenation stage.[1] Other notable landmarks within the Honolulu Volcanics include nearby Hanauma Bay and the well known Diamond Head crater.[1]

Koko Crater, Hanauma Bay and other nearby tuff cones form the Koko Rift Zone, which marks the latest episode of volcanic activity on the island of Oahu.[1] Radiocarbon dating suggests that the latest eruption within the Koko Rift Zone occurred 7,000 years ago,[1] although the validity of these results are disputed.[2] Its elevation is 1,208 ft (368 m), making it the tallest and most preserved tuff cone in the area.[1]

Trail

During World War II, the US military built bunkers on top of Koko Crater with a railroad leading to its summit.[3] In 1966, the air force ceded administration of Koko Crater over to the City of Honolulu. It was then renamed to the Koko Head Regional Park.[3] Within this park is the Koko Crater Trail, which is a 1.8 mile long trail that uses the now-abandoned railroad as its pathway.[4][5]

In February 2009, a man stabbed 2 other people on the Koko Crater Trail.[6][7] He was later acquitted of all charges by reason of insanity and was given permission to attend college, although his lack of punishment has been criticized by Nicholas Iwamoto, who was one of the victims of the incident.[8][9]
