Punchbowl Crater

Punchbowl Crater is an extinct volcanic tuff cone located in Honolulu, Hawaii. 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 Koolau Mountain Range. The volcano is most likely a monogenetic volcano, meaning that it only erupted once.

Although there are various translations of the Punchbowl's Hawaiian name, "Puowaina," the most common is "Hill of Sacrifice." This translation closely relates to the history of the crater. The first known use was as an altar where Hawaiians offered human sacrifices to their gods and killed violators of the many taboos.
