Australia - The Outback
The Outback
Although unrelated to geological forces, the world's largest coral formation, the Great Barrier Reef stretches for 1,245 mi (2,003 km) along Australia's northeast coast. Most of Australia is referred to as outback—monotonous desert and semi-desert flatness, broken only by scrub, salt lakes which are actually dry lakebeds most of the year, and a few spectacular sandstone proturburances like Ayers Rock (known by Australian aborigines as Uluru) and the Olgas (Kata Tjuta).
