This creek flows through the bedrock of an ancient lava flow. It
was deposited by an extinct volcano located in the Bay of
Islands in New Zealand. Basalt lava usually flows in calm and
fluid streams. Once such lava streams came to rest, the internal
cooling of the lava can take a long time, allowing hexagonal
columns to develop, that contour the internal cracks of the
cooling process. Today this creek flows on top of these basalt
columns. The brinks of this ancient lava flow are deeply hidden
under the compact subtropical vegetation. Pentax K2, Pentax
