Kata Tjuta, sometimes written Tjuṯa (Kata Joota), and also known as Mount Olga (or colloquially as The Olgas), are 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. 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.
