Maori legend has it that the Moeraki Boulders scattered along Koekohe Beach are the remains of eel baskets, gourds, and sweet potatoes from a large canoe wreck. Scientifically, the spherical rocks are the result of a natural process known as concretion, where grains of sand and stone combine to form these masses. Reaching a diameter of up to six feet, these boulders dot the eroded Otago coastline along the South Island of New Zealand.
