Kata Tjuṯa, also known as The Olgas, is a group of domed rock formations in central Australia. It holds cultural significance for the Anangu people, who associate it with ancient Dreamtime stories. The formation consists of conglomerate rock, shaped over millions of years through geological processes. The tallest peak, Mount Olga, was named in honour of Queen Olga of Württemberg. The site is part of the Uluṟu-Kata Tjuṯa National Park and used for cultural ceremonies.
