Pancake Rocks and Blowholes: Introduction

Countless marine creatures lived and died above a slowly rising seafloor, and their shells drifted downward like snow, settling into layers of almost pure calcium carbonate. The result of that quiet accumulation now stands at Dolomite Point on New Zealand's West Coast: pale limestone cliffs carved into formations so precisely layered they look like stacks of giant pancakes, each slab separated by thin dark seams of softer stone. When the Tasman Sea surges through the caverns below at high tide, it erupts through vertical blowholes in roaring columns of salt spray, a reminder that the same ocean that built these rocks is still reworking them.

Pancake Rocks and Blowholes: Shells All the Way Down

The Pancake Rocks began forming during the Oligocene period, between 22 and 30 million years ago, when a cluster of low-lying islands sat in warm coastal waters off what is now the West Coast. Marine organisms thrived in extraordinary diversity, and as they died their shells accu...

Pancake Rocks and Blowholes: When the Sea Exhales

During incoming swells, particularly at high tide, the Tasman Sea forces itself into a network of caverns and surge channels carved beneath the headland. Compressed by narrowing passageways, the water finds vertical shafts and explodes upwa...

Pancake Rocks and Blowholes: A Continent Mostly Drowned

During the Oligocene, Zealandia reached its maximum submergence. Only a scattering of islands broke the surface, and the shallow seas teemed with life. It was this ...

The Pancake Rocks sit within Paparoa National Park, immediately adjacent to the village of Punakaiki, and a network of walkways threads through and around the formations. Parts of the path are wheelchair-accessible; other sections descend carved stairways into the rock faces, bri...
