The Black Cliff
And some geology students.
The fascinating geological history of Hallett Cove is traced in its dark Pre-Cambrian rocks which were once under a sea that covered a vast area of South Australia 600 million years ago.
About 500 million years ago the region was squeezed by massive earth movements which folded rocks and formed them into mountain ranges. Such folds are clearly seen at the southern foot of Black Cliff and along the wave cut platform to the north.
