The Olgas or Kata Tjuta in the Red Centre of Australia...hard one eh?
Kata Tjuta, also known as Mount Olga or colloquially as The Olgas, are a group of large domed rock formations located about 365 km (227 mi) southwest of Alice Springs, in the southern part of the Northern Territory, central Australia. Uluru/ Ayers Rock 25 km (16 mi) to the east, and Kata Tjuta / Mount Olga form the two major landmarks within the Uluru-Kata Tjuta National Park.
The 36 domes that make up Kata Tjuta are composed of conglomerate, a sedimentary rock consisting of cobbles and boulders of varying rock types including granite and basalt, cemented by a matrix of sandstone.
The highest point, Mount Olga, is approximately 546 m (1,791 ft) above the surrounding plain.
