Limestone Spires Rising From Yellow Sand

The Pinnacles Desert lies in Nambung National Park, about two hours' drive north of Perth in Western Australia. Thousands of limestone pillars rise from yellow sand, some about 3.5 meters tall, creating an eerie landscape that changes color through the day.

The limestone came from ancient seashells that were broken down into sand and built into dunes. Rain dissolved and cemented the lime, and wind later blew away the loose sand, exposing the hardened pillars. A popular story says early Dutch sailors thought they had seen a ruined city.

Visitors reach the area along the Indian Ocean Drive and the nearby town of Cervantes. A discovery centre explains the geology, while emus and western grey kangaroos wander among the spires at dawn and dusk. Wildflowers bloom in spring, and Lake Thetis nearby has living stromatolites built by microbes.
