The Geocache of the Week takes us to a striking location. The New Zealand beach looks like a scene from a science fiction movie.
Local Maori legend has it that the boulders are the remains of eel baskets, kumara (sweet potato), and calabashes (a long, squash-like melon grown on a vine) that washed ashore from the wreck of a large sailing canoe hundreds of years ago.
Scientists explain that the boulders were formed over the course of millions of years by a layering process similar to the formation of oyster pearls. The seabed was lifted to form coastal cliffs that have eroded over time causing the boulders to tumble onto the beach.
One geocacher logging a visit writes, “What a great location to come to and explore! Really enjoyed the walk on the beach. It is quite amazing how spherical the concretions are. Thanks for an added reason to stop on my drive south!”
