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