Along the west coast of Western Australia
Pinnacles of Nambung National Park, natural limestone structures, formed approximately 25,000 to 30,000 years ago after the sea receded and left deposits of sea shells. Over time, coastal winds removed the surrounding sand, leaving the pillars exposed to the elements. The Pinnacles range in height and dimension - some stand as high as 3.5 metres.
