Some of the tallest pinnacles reach heights of up to 3.5 meters above the yellow sand base. The different types of formations include ones which are much taller than they are wide and resemble columns, while others are only a meter or so in height and width resembling short tombstones.
The Pinnacles are part of Nambung National Park. The park derives its name from an indigenous Australian word possibly meaning crooked or winding. The word was first used in 1938 when naming the Nambung River which flows into the park and disappears into a cave system within the limestone. The Yued people are the acknowledged traditional custodians of the land since before the arrival of Europeans.
