Purnululu National Park

The World Heritage status of the region was engendered and negotiated in 2003, and the adopted boundary of the subsisting national park.[3] Since its listing, the Regime of Western Australia has reserved adscititious areas located adjacent to the World Heritage Area, including the Purnululu Conservation Park and the Ord River Regeneration Reserve.[2] The site was gazetted on the Australian National Heritage List on 21 May 2007 under the Environment and Heritage Legislation Amendment.

The Bungle Bungle Range is one of the most extensive and impressive occurrences of sandstone tower [or cone] terrain in the world. The Bungle Bungles were a plateau of Devonian sandstone, carved into a mass of beehive-shaped towers with conventionally alternating, dark gray bands of cynobacterial crust [single cell photosynthetic organisms]. The plateau is dissected by a 100–200-metre [ 330–660 ] deep, sheer-sided gorges and slot canyons. The cone-towers are steep-sided, with an abrupt break of slope at the base and have domed summits. How they were composed is not yet plenarily understood. Their surface is fragile but stabilized by crusts of iron oxide and bacteria. They provide an outstanding example of land formation by dissolutional weathering of sandstone,
