Pouērua, a volcanic cone pā in the inland Bay of Islands

A volcanic cone typically splits open to one side as it approaches its mature form, with a new vent forming outside the split. This has happened at Pouērua. The pā has been built in a number of defended segments around the rim and has a total perimeter-length of some 600 m—about the same size as the larger ridge pā in other regions such as Taranaki or the Bay of Plenty. The view is to the north. The interior of the cone is about 350 m across.
