Head of Bight, South Australia

The head of the Great Australian Bight is most well known as a popular vantage point for whale watching, however even sans whales the indigenous run Head of Bight facility is one to put on the list. Walking out of the visitor centre in the direction of the ocean my mouth literally dropped as the expanse of turquoise blue penetrated my eyes. The view is in a word STUNNING and the beauty difficult to capture in photographs. The Bunda Cliffs that begin at the Head of Bight and extend the length of the Nullarbor Plain are made up of three distinct types of limestone. The first layer at the base is called Wilson Bluff Limestone, formed by the skeletons of decomposed marine organisms when the oceans were much higher than they are today. The second layer in the middle is called Nullarbor Limestone and began forming from sedimentation about 25 million years ago. The third and final layer on the top is called Bridgewater Formation and is windblown calcareous sand formed between 1.6 million years and 100,000 years ago. Nature is amazing and incredibly awe inspiring.
