context_page_description: The Auckland Domain is a large park in Auckland, New Zealand. It is the oldest park in the city, and at 75 hectares is one of the largest. Located in the central suburb of Grafton, the park contains all of the explosion crater and most of the surrounding tuff ring of the Pukekawa volcano.
  The park is home to one of Auckland's main tourist attractions, the Auckland War Memorial Museum, which sits prominently on the crater rim. Several sports fields occupy the floor of the crater, circling to the south of the cone, while the rim opposite the Museum hosts the cricket pavilion and Auckland City Hospital. The Domain Wintergardens, with two beautiful glass houses, lie on the north side of the central scoria cone. The fernery has been constructed in an old quarry in part of the cone. The duck ponds lie in the northern sector of the explosion crater, which is breached to the north with a small overflow stream.
context_section_description: The Auckland Domain volcano, Pukekawa, is one of the oldest in the Auckland volcanic field, and consists of a large explosion crater surrounded by a tuff ring with a small scoria cone (Pukekaroro) in the centre of the crater.  Its tuff ring, created by many explosive eruptions, is made of a mixture of volcanic ash, lapilli and fragmented sandstone country rock. Its eruption followed soon (in geological terms) after the neighbouring Grafton Volcano was created, destroying that volcano's eastern parts and burying the rest.
  Originally, the crater floor was filled with a lava lake, the western half collapsed slightly and became a freshwater lake which later turned into a swamp and slowly filled up with alluvium and sediment, before being drained by Europeans for use as playing fields and parkland.  These origins are still somewhat visible in that the Duck Ponds are freshwater-fed from the drainage of the crater.
