Kata Tjuta had a similar formation process as Uluru 16 miles away, and is equally impressing.

Kata Tjuta, meaning "many heads" in the Anangu language, is one of the large rock formations in the Uluru / Kata Tjuta National Park.
550 million years ago, creeks from the nearby mountains brought water-smoothed rock to the surrounding plains and deposited them there in fan-like shapes in kilometer-thick layers. About 50 million years later, the plains had become the bottom of a sea. The deposited rocks were compressed by the increasing weight of sediments from the sea to become a layer of conglomerate rock. The rock layer was later slightly tilted by geological forces and its upper tip exposed by weathering of the surrounding softer rock. Cracks and joints in the rock layer were especially subject to erosion. Thus, the distintive dome structure was formed. In summary, Kata Tjuta is the uppermost part of a huge rock layer that probably continues below the ground for up to 5 to 6 kilometres.
