Spectacular limestone formations largely remained unknown until 1967, when a reserve was formed to protect the prominent pillars. Rising dramatically out of the desert floor, The Pinnacles resemble weathered tombstones and number in the thousands. Together, they make for an incredible sight as sand from the coastal dunes constantly blows through the otherworldly looking landscape. While debates are ongoing as to how their distinctive shapes formed, it is generally agreed that they are made out of the limestone from seashells as the region used to be submerged millennia ago. Now, The Pinnacles make for a popular tourist attraction. Western grey kangaroos can often be spotted between them, as well as the occasional emu, dingo, and honey possum. Located at Nambung National Park.
