Uluru - Massive sandstone

Uluru, or Ayers Rock, is a massive sandstone monolith in the heart of the Northern Territory’s arid "Red Centre". The nearest large town is Alice Springs, 450km away. Uluru is sacred to indigenous Australians and is thought to have started forming around 550 million years ago.

  

It’s within Uluru-Kata Tjuta National Park, which also includes the 36 red-rock domes of the Kata Tjuta (colloquially “The Olgas”) formation.Uluru is sacred to the Pitjantjatjara Anangu, the Aboriginal people of the area. The area around the formation is home to an abundance of springs, waterholes, rock caves and ancient paintings. 

Uluru is listed as a UNESCO World Heritage Site. Uluru and Kata Tjuta, also known as the Olgas, are the two major features of the Uluṟu-Kata Tjuṯa National Park. Uluru is one of Australia's most recognisable natural landmarks. Both Uluru and the nearby Kata Tjuta formation have great cultural significance for the Aṉangu people, the traditional inhabitants of the area, who lead walking tours to inform visitors about the local flora and fauna, bush food and the Aboriginal dreamtime stories of the area.
