Kata Tjuta (Olgas), Northern Territory, Australia. Kata Tjuta (sometimes spelled Kata Joota; Pitjantjatjara: Kata Tjuṯa), also known as the Olgas, is a group of large, domed rock formations or bornhardts located about 365 km (227 mi) southwest of Alice Springs, in the southern part of the Northern Territory, central Australia. Kata Tjuta and Uluru, 25 km (16 mi) to the east, and Kata Tjuta / Mount Olga form the two major landmarks within the Uluru-Kata Tjuta National Park. This park is considered sacred to the Aboriginal people of Australia. The 36 domes that make up Kata Tjuta / Mount Olga cover an area of 21.68 km2 (8.37 sq mi), 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.
