These photographs are all scans of 35mm negatives, taken at Hallett Cove Conservation Park, in 2000.

The darker, chocolate-coloured rocks that were lying in the full sun were quite hot to touch. These rocks were once part of the layered cliffs, that have been dated by geologists to have formed about 600 million years ago.

The rocks here look as though they have cracked into sections and had more liquid rock seep into the cracks from below, before setting hard.

Fascinating patterns from the constant erosion of structured rock, from the tides and the sea waves.
