| ||In the heart of Bungle Bungle National Park (called Purnululu by the aborigines), in western Australia, stands a series of sandy columns and domes approximately 330 feet (100 m) high. This labyrinth of gorges covers 310 square miles (770 km2). The rocks are made up of solidiﬁed sediment from the erosion of former mountains, ﬁssured and raised from the force of motion of the Earth’s crust. Their tigerlike orange-and-black appearance is the result of alternating layers of silica and lichen. Known for centuries by the aborigines, this site was revealed to the public only in 1982 and was declared a national park in 1987.
