It is the location of the National Memorial Cemetery of the Pacific. The crater was formed some 75,000 to 100,000 years ago during the secondary activity of the Honolulu Volcanic Series. A crater resulted from the ejection of hot lava through cracks in the old coral reefs which, at the time, extended to the foot of the Koʻolau Mountain Range. The volcano is most likely a monogenetic volcano, meaning that it only erupted once.
