Pancake rocks

Went for a drive to Punakiki on the West Coast of New Zealand today, We are standing about 150 feet above sea level (at a guess) and as the waves surge in the blow holes put on an amazing display. I have pasted the bit from the Dept of Conservation website below.

The Pancake Rocks are most spectacular in the Putai area. They were formed 30 million years ago from minute fragments of dead marine creatures and plants landed on the seabed about 2 km below the surface. Immense water pressure caused the fragments to solidify in hard and soft layers. Gradually seismic action lifted the limestone above the seabed. Mildly acidic rain, wind and seawater sculpted the bizarre shapes.
