Photographer's Note

Purnululu National Park. "The Bungle Bungle landscape comprises a mass of beehive-shaped towers with regularly alternating, dark gray bands of cynobacterial crust (single cell photosynthetic organisms). The plateau is dissected by 100-200 m deep, sheer-sided gorges. The cone-towers are steep-sided, with an abrupt break of slope at the base and have domed summits. 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, with removal of sand grains by wind, rain and sheet wash on slopes." ( The Encyclopedia of Earth)
