The Olgas also called Kata Tjuta is within Uluṟu-Kata Tjuṯa National Park and is what geologists refer to as a monadnock – a large isolated rock remnant that sits on an eroded plain. The monadnock stands abruptly on the plains because it is more resistant to erosion than the surrounding rocks in the countryside.

There are 36 dome structures that make up the Olgas which cover 8.37 square miles (21.7 sq km). The Olgas are higher than Ayers Rock and extend 1,791 ft (546 m) above the surrounding plain. The rock is similar to Ayers Rock – primarily reddish sandstone with intermixed conglomerate. Humans have lived in the region for at least 10,000 years. Explorers Ernest Giles and William Gosse were the first Europeans to see The Olgas in 1872.

Kata Tjuta

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 form the two major landmarks within the Uluru-Kata Tjuta National Park.
