The Oldest Limestone Spiers
The limestone spiers that make up the Pinnacles have formed over millions of years ago. The Nambung National Park, that's 250 kilometres north of Perth and covers an area of 17,487 hectares is home to the Pinnacles. The statuesque limestone pillars are up to three metres high, rising out of the sand like ancient ruins.
These most unusual wind-carved edifices were formed in the sand 25,000 to 30,000 years ago after the sea receded and deposits of sea shells remained behind. Over time the elements removed the surrounding sand, leaving the pillars isolated and open to wind degradation.
