Boggust Park Crater

Boggust Park Crater is a volcano in the Auckland volcanic field, New Zealand. Located in the Favona area of the Māngere suburb, it is one of Auckland city's older volcanoes. It was first recognised as a volcano in 2011. The park in which it is located is named after Ralph Boggust, former superintendent of Manukau Parks Dept.

The volcano has a 300–400 m diameter crater surrounded on three sides by a 6–8 m high semi-circular tuff ring with steep inner slopes and gentler outer slopes. In places the crest of the tuff ring has been flattened off by bulldozing during subdivision in the 1990s. The tuff ring is breached to the north-east, presumably by the sea during the Last Interglacial warm period, about 130,000 years ago, when the sea level was 5–6 m above the present.
