Aggregate Rock, Olga's , Northern Territory, Australia

Kata Tjuta, also known as Mount Olga(or Olga's) are a group of large domed rock formations located about 25 KM to the west of Uluru and 365 Km southwest of Alice Springs.

Consisting of 36 domes covering an area of 21.68 Km, they are composed of conglomerate, a sedimentary rock consisting of cobbles and boulders of varying rock types.

The two most common are granite and basalt, cemented by a mixture of sandstone.

 Mount Olga , the highest summit is 1066 m above sea level  and approximately 546 m above the surrounding plain. It is thus about 203 m higher than Uluru. The Docker River road terminates at Kata Tjuta.

To the Pitjantjajara, the local aborigines, the name Kata Tjuta means "many heads", the site is as sacred to the indigenous people as Uluru.

The alternate name, The Olga's, comes from the tallest peak Mt. Olga, which was named in 1872, by Ernest Giles in honor of Queen Olga of Wurttemberg.

On 15 December 1993, a dual naming policy was adopted that allowed official names consisting of both the traditional Aboriginal name and the English name. As a result, Mount Olga was renamed Mount Olga / Kata Tjuta.

On 6 November 2002, following a request from the regional Tourism Association, the order of the dual names were officially reversed to Kata Tjuta / Mount Olga.

There are many dreamtime legends associated with this place and indeed everything in the vicinity including, of course, Uluru. A number of legends surround the great snake Wanambi who is said to live on the summit of Mount Olga and only comes down during the dry season.

Many ceremonies were, and are still carried out here, particularly at night. One of these former ceremonies included a type of public punishment that in extreme cases included death
