The Pinnacles

The Pinnacles are limestone formations in Nambung National Park near Cervantes in Western Australia. They form one of Australia's most unique natural landscapes. There are thousands of pinnacles in the area, the tallest of which reaches a height of 3.5 m. Three theories exist as to how the pinnacles were created. The first suggests they formed as a result of extensive weathering of limestone deposits. The second states that plants played a major role in their formation. The third theory presented by guides on site is that the region used to be a forest, and the pinnacles were formed through the preservation of tree casts and later wind erosion. The Pinnacles are visited each year by approximately 250,000 tourists.
