Brown's Island (also known as Motukorea) in Waitemata Harbour, New Zealand, is composed of the remnant of a tuff ring (right side), scoria cones (center), and lava flows that form the flat peninsula in the foreground. It is one of 50 Pleistocene-to-Holocene centers in the Auckland Volcanic Field. The low-angle slopes of lava flows from Rangitoto, the only Holocene center, are visible to the north in the background. Photo by B. Thompson (published in Green and Short, 1971).
