New 7 Natural Wonders of the World

New Seven Wonders of Nature-One of 28 nominees. Winners will be announced in 2011.

 

Uluru-(Ayers Rock)
Ayers Rock
Australia
New Seven Wonders of Nature
Earth's Natural Wonders in Australia & Oceania
The Rock is arkose, a course-grained sandstone rich in feldspar at least 2.5 km thick. Uplifting and folding between 400-300 mya turned the sedimentary layers nearly 90 degrees to their present position. The surface has then been eroded.

Uluru is one of Australia's most recognisable natural icons. The world-renowned sandstone formation stands 348 m (1,142 ft) high (863 m/2,831 ft above sea level) with most of its bulk below the ground, and measures 9.4 km (5.8 mi) in circumference. Both Uluru and Kata Tjuta have great cultural significance for the Anangu Traditional landowners, who led walking tours to inform visitors about the local flora and fauna, bush foods and the Aboriginal dreamtime stories of the area.

Uluru is notable for appearing to change colour as the different light strikes it at different times of the day and year, with sunset a particularly remarkable sight when it briefly glows red. Although rainfall is uncommon in this semiarid area, during wet periods the rock acquires a silvery-grey colour, with streaks of black algae forming on the areas that serve as channels for water flow.

Kata Tjuta, also called Mount Olga or The Olgas, is another rock formation about 25 km (16 mi) west of Uluru. Special viewing areas with road access and parking have been constructed to give tourists the best views of both sites at dawn and dusk.

Uluru is an inselberg, literally "island mountain", an isolated remnant left after the slow erosion of an original mountain range. Uluru is also often referred to as a monolith, although this is a somewhat ambiguous term because of its multiple meanings, and thus a word generally avoided by geologists. The remarkable feature of Uluru is its homogeneity and lack of jointing and parting at bedding surfaces, leading to the lack of development of scree slopes and soil. These characteristics led to its survival, while the surrounding rocks were eroded. For the purpose of mapping and describing the geological history of the area, geologists refer to the rock strata making up Uluru as the Mutitjulu Arkose, and it is one of many sedimentary formations filling the Amadeus Basin.[2]

 

Sighted in 1872 by Ernest Giles, the rock was named for former South Australian premier Sir Henry Ayers. In 1985 official ownership of Ayers Rock was given to the Aboriginals, who thereupon leased the rock and the national park to the government for 99 years. Visitors arrive at the rock via Alice Springs, 280 miles (450 km) northeast by road. The buildings of the tourist resort near Ayers Rock are coloured to blend in with the surrounding desert. The rock and the surrounding park were designated a World Heritage site in 1987.[3]
