Nature, it is said, abhors straight lines almost as much as vacuums, but off the point at the south end of Kaiti Beach these peculiar rock ribs, revealed by the sea at low tide, look as if they were laid out to survey pegs and put down in concrete.
They jut out from the papa shelf which is a characteristic of beaches in the area. Picture at left shows butt end of layer formation at the point. Below, the ribs extending out to sea for a considerable distance, maintaining remarkable parallelism and uniform level for more than a hundred yards.
