Question: Punchbowl Crater is an extinct volcanic tuff cone and the location of a memorial to honor men and women who served in wthat?
Context: Maungataketake (also Ellett's Mount) is one of the volcanoes in the Auckland volcanic field in New Zealand.  It had a 76 m high scoria cone, beside a 100 m wide crater, before they were quarried away.  It was the site of a pā.  Layers of volcanic tuff and ash from Maungataketake overlay the fallen trunks of the nearby Ihumatao fossil forest. Punchbowl Crater (546 ft) is an extinct volcanic tuff cone located in Honolulu, Hawaii.  It is the location of the National Memorial Cemetery of the Pacific. The National Memorial Cemetery of the Pacific (informally known as Punchbowl Cemetery) is a national cemetery located at Punchbowl Crater in Honolulu, Hawaii.  It serves as a memorial to honor those men and women who served in the United States Armed Forces, and those who have given their lives in doing so.  It is administered by the National Cemetery Administration of the United States Department of Veterans Affairs and is listed on the National Register of Historic Places.  Millions of visitors visit the cemetery each year, and it is one of the most popular tourist attractions in Hawaii. Mount Zaō (蔵王山 , Zaō-zan ) is a complex volcano on the border between Yamagata Prefecture and Miyagi Prefecture in Japan.  It consists of a cluster of stratovolcanoes and is the most active volcano in northern Honshu.  The central volcano of the group includes several lava domes and a tuff cone, Goshiki-dake, which contains a crater lake named "Okama" (御釜).  Also known as the "Five Color Pond" (五色沼, "goshiki numa") because it changes color depending on the weather, it lies in a crater formed by a volcanic eruption in the 1720s.  The lake is 360 m in diameter and 60 m deep, and is one of the main tourist attractions in the area. The Honolulu volcanic series is a set of monogenetic volcanic events on the Hawaiian island of Oahu.  The events, which have been dated to between 800,000 and 30,000 years before the present, created several notable island features, including Diamond Head, the Punchbowl Crater, Hanauma Bay, Mānana Island and the youngest, Koko Crater.  Most people don't consider those craters as volcanoes.  They are thought to be extinct vents of the Ko'olau Range. Makiki is an area of Honolulu, Hawaiʻ i located northeast of downtown Honolulu generally stretching east to west from Punahou Street to Pensacola Street and north to south from Round Top Drive/Makiki Heights Drive to Lunalilo Freeway.  Punchbowl, an extinct tuff cone, and Tantalus, tower over the Makiki neighborhood.  The geographic layout of this area is primarily older houses, smaller apartment buildings, and side streets.  Major roadways include Punahou Street, Pensacola Street, Piʻ ikoi Street, Nehoa Street, and Wilder Avenue.  The area also includes a fire station, hospital, public school system, private schools including Punahou School, several churches of various denominations, a library, a community center, market place, and parks.  The valley heights have hiking trails owned by the state for public use.  The valley heights are mostly underdeveloped leaving room for a non-profit conservation organization named Hawaii Nature Center, to hold a small property providing conservation education and work opportunity to local schools students. Mount Tantalus (Puu-ohia), is an extinct cinder cone in the southern Koʻ olau Range on the Hawaiian Island of Oʻ ahu.  It also has a summit crater, Tantalus Crater.  The cinder cone formed after the demise of Koʻ olau Volcano, during a time of rejuvenated stage volcanism in southeastern Oʻ ahu that also formed Punchbowl Crater, Diamond Head and Koko Head.  Tantalus overlooks the modern city of Honolulu, which is built on top of Tantalus cinders. Koko Head is the headland that defines the eastern side of Maunalua Bay along the southeastern side of the Island of Oʻ ahu in Hawaiʻ i.  On its western slope is the community of Portlock, a part of Hawaiʻ i Kai.  Koko Head (at 642 ft or 196 m) is an ancient tuff cone that is somewhat dwarfed by its neighboring tuff cone, Koko Crater, with its peak, "Kohelepelepe" (or "Puʻ u Mai"), rising to 1208 ft or 368 m. Koko Head itself has three significant depressions or old vents, the largest of which forms the well-known Hanauma Bay.  Koko Head's last eruption was 30,000–35,000 years ago. Diamond Head is a volcanic tuff cone on the Hawaiian island of Oʻ ahu and known to Hawaiians as Lēʻ ahi, most likely from lae 'browridge, promontory' plus ʻ ahi 'tuna' because the shape of the ridgeline resembles the shape of a tuna's dorsal fin.  Its English name was given by British sailors in the 19th century, who mistook calcite crystals on the adjacent beach for diamonds. Seongsan Ilchulbong, also called ‘Sunrise Peak’, is an archetypal tuff cone formed by hydrovolcanic eruptions upon a shallow seabed about 5 thousand years ago.  Situated on the eastern seaboard of Jeju Island and said to resemble a gigantic ancient castle, this tuff cone is 182 meters high, has a preserved bowl-like crater and also displays diverse inner structures resulting from the sea cliff.  These features are considered to be of geologic worth, providing information on eruptive and depositional processes of hydromagmatic volcanoes worldwide as well as past volcanic activity of Seongsan Ilchulbong itself.
