Lava tube. View up through an extinct lava tube. Lava tubes form when the surface of a lava flow cools and solidifies,while the interior remains molten. The molten lava then flows through a hollow passage of cooled rock. When the lava stops flowing the empty tube is left. Photographed on Rangitoto Island,a volcanic island in the Hauraki Gulf near Auckland,New Zealand | |
