The Pinnacles Desert, Nambung National Park, Western Australia ~ These limestone formations were formed from seashells in an earlier epoch. At the end of the Pleistocene glaciation the climate in Western Australia dried out & warmed up, & the vegetation died off. Fine sediment was gradually removed by wind in the area now known as the Pinnacles Desert. Where the tree roots & cracks breached the caliche capping, the wind was able to blow away the loose sand. The caliche-capped ‘pinnacles’ survive.
