| has gloss | eng: Browns Island or Motukorea is a small New Zealand island, in the Hauraki Gulf north of Musick Point, one of the best preserved volcanoes in the Auckland Volcanic Field. It erupted 8,000 to 12,000 years ago, exhibiting a range of activity including ash, lava and scoria eruptions. Due to centuries of cultivation, little native bush remains except on the north-eastern cliffs, leaving the volcanic landforms easily visible. The island consists of several scoria cones, a small remnant of a tuff crater, and the higher portions of the lava flows. The area was dry land when the eruptions occurred, but much of the lava is now submerged at high tide. |
