There is a bit of a mystery to the Pancake Rocks on the South Island of New Zealand. Nobody really knows why they look the way they do. Punakaiki is the gateway to the dramatic limestone country of the Paparoa National Park. It lies halfway between Greymouth and Westport on one of the most spectacular coastal highways in New Zealand and it is famous for the Pancake Rocks.Nature began this work of art about 30 million years ago. Over thousands of years, alternating layers of small marine creatures and sand became buried and compressed on the ocean floor. This created areas with multiple layers of hard limestone and softer sandstone. Earthquake activity then lifted the ocean floor high and dry, and those slow motion artists – the rain and the wind – began to erode the softer sandstone. The outcome is cliffs and ravines with hundreds of horizontal slices along their vertical faces, like huge stacks of pancakes.
