Kata Tjuta, also known as Mount Olga (or colloquially as The Olgas), are a group of large domed rock formations located about 365 km southwest of Alice Springs, in the southern part of the Northern Territory, central Australia. Uluru, 25 km to the east and Kata Tjuta form the two major landmarks within the Uluru-Kata Tjuta National Park. The 36 domes, covering an area of 21.68 kmē, 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.
