The Moeraki Boulders in New Zealand are a group of large dome-shaped “stones on Koekohe Beach on Otago Coast. These boulders are not actually stones, but the concretions of calcium carbonate. Local legend says that these stones are made of the remains of eel baskets, calabashes, and kumara washed ashore from the after the legendary canoe, the Araiteuru was wrecked at nearby Shag Point. They can weigh up to several tons and were originally formed in ancient sea floor sediments almost 60 million years ago. How cool are these.
