Ayers Rock, also known as Uluru, is a large sandstone monolith in the Uluru-Kata Tjuta National Park in the Northern Territory, Australia. It is one of the country's most recognisable natural landmarks and has been a popular tourist destination since the late 1930s. Uluru is sacred to the Aboriginal people of the area, known as the Aṉangu or Pitjantjatjara. The rock was first sighted by Europeans in 1872 and named by surveyor William Gosse in 1873 after Sir Henry Ayers, the then Chief Secretary of South Australia.

What You'll Learn
Ayers Rock is a type of arkose sandstone
Ayers Rock, also known as Uluru, is a type of arkose sandstone. It is a large sandstone monolith that rises abruptly from the flat plains of spinifex grass in the Northern Territory of central Australia. The formation of this arkose sandstone began about 500 million years ago when sandy sediments eroded from high mountains composed largely of granite.
The average composition of Ayers Rock is approximately 50% feldspar, 25-35% quartz, and up to 25% of other rock fragments. This high proportion of feldspar, along with the presence of other minerals, gives the sandstone its distinctive orange-brown colour. The surface oxidation of its iron content also contributes to its unique hue, which ranges from orange to red.
Ayers Rock is a sacred site for the local Pitjantjatjara Aboriginal tribe, who have owned and administered the land on which the rock stands since it was returned to them by the Australian government in 1985. The Aborigines attach spiritual significance to the site and request that visitors do not climb it.
The rock formation is a popular tourist destination, attracting visitors with its impressive size and the changing colours it displays at sunrise and sunset. It is one of Australia's most recognisable natural landmarks and has been designated a UNESCO World Heritage Site.

It is sacred to the Aboriginal Pitjantjatjara people
Uluru, also known as Ayers Rock, is a large sandstone monolith in the Uluru-Kata Tjuta National Park in the southern part of the Northern Territory, Australia. It is sacred to the Aboriginal Pitjantjatjara people, who have long revered this site and refer to it as "Uluru". The name "Uluru" was officially adopted in 1993 as part of a dual-naming policy that recognises both the traditional Aboriginal name and its English name.
The Aboriginal Pitjantjatjara people are the traditional owners of the land on which Uluru stands. They have a deep spiritual connection to this place and consider it a sacred site. The area surrounding Uluru is rich in natural features, including springs, waterholes, rock caves, and ancient paintings, making it one of the most important indigenous sites in Australia.
In recognition of the cultural and historical significance of Uluru to the Aboriginal Pitjantjatjara people, the Australian government returned ownership of the land to them in 1985. This handover was made with the condition that the land would be leased back to the National Parks and Wildlife agency for 99 years for joint management.
The Pitjantjatjara people attach great spiritual significance to Uluru and have requested that visitors refrain from climbing it. They believe that the site is hollow beneath the ground and houses an energy source known as "Tjukurpa" or "dream time". This term also refers to the record of the activities and journeys of ancestral beings.
Uluru is a significant landmark, not just for its natural beauty but also for its cultural and spiritual importance to the Aboriginal Pitjantjatjara people. Its recognition as a UNESCO World Heritage Site further underscores its value, making it one of Australia's most famous and recognisable natural icons.

The rock formation is around 500 million years old
The rock formation of Uluru, also known as Ayers Rock, is around 500 million years old. It is a large sandstone monolith that rises abruptly from the flat plains of spinifex grass in the Northern Territory of central Australia. Uluru is sacred to the local Pitjantjatjara Aboriginal tribe, who have long administered the land on which the rock stands. The formation is approximately 3.6 kilometres long, 1.9 kilometres wide, and almost 10 kilometres in circumference, with most of its bulk lying underground.
Uluru is one of Australia's most recognisable natural landmarks and has been a popular destination for tourists since the late 1930s. It is a World Heritage Site and offers a variety of adventures and experiences for visitors, including hiking around the base of the rock and exploring the surrounding outback destinations. The rock is known for its striking orange-red hue, which is due to the surface oxidation of its iron content.
The name "Ayers Rock" was given to the formation by surveyor William Gosse in 1873, in honour of Sir Henry Ayers, who was the Chief Secretary of South Australia at the time. In 1993, a dual naming policy was adopted, and the official name became "Ayers Rock/Uluru". The order of the names was reversed in 2002 at the request of the Regional Tourism Association in Alice Springs, and it is now officially known as "Uluru/Ayers Rock".
Uluru has a rich Aboriginal history and is considered a sacred site by the local Pitjantjatjara people. The Aborigines attach spiritual significance to the rock and believe that it is hollow below ground, with an energy source they call "Tjukurpa" or "dream time". The land surrounding Uluru is home to an abundance of springs, waterholes, rock caves, and ancient paintings, further adding to its cultural and historical value.
The formation of Uluru began around 500 million years ago when it was part of the ocean floor at the centre of Australia. The sandy sediment that hardened to form the rock was eroded from high mountains composed largely of granite. Over time, this sediment built up and was compressed, forming the sandstone monolith that we see today.

It is 348 metres high and 9.4km in circumference
Ayers Rock, also known as Uluru, is a large sandstone monolith that rises 348 metres (1,142 feet) above the surrounding plain. It is an impressive and distinctive landmark, rising abruptly from the flat plains of spinifex grass. The rock is sacred to the local Pitjantjatjara Aboriginal tribe, who own and administer the land on which it stands. They attach spiritual significance to the site and request that visitors do not climb it.
Uluru is located in the Uluru-Kata Tjuta National Park in the Northern Territory, in central Australia. The National Park was founded in 1950 as the 'Ayers Rock-Mount Olga National Park' and changed to its current title in 1995. The area surrounding the rock features an abundance of springs, waterholes, rock caves, and ancient paintings.
Uluru is oval in shape, measuring 3.6 km (2.2 miles) long and 1.9 km 1.5 miles wide, with a circumference of 9.4 km (5.8 miles). It is composed of arkosic sandstone, which contains a high proportion of feldspar. The sandy sediment that formed this arkose was eroded from high mountains composed largely of granite. The average composition of the rock is approximately 50% feldspar, 25-35% quartz, and up to 25% of other rock fragments.
The rock's height of 348 metres, combined with its oval shape and large circumference, makes it a significant and imposing presence on the landscape. Its size and distinctive shape have contributed to its status as one of Australia's most recognisable natural landmarks and a popular tourist destination.
Uluru is best known for its striking colour, which changes depending on the position of the sun. The surface oxidation of its iron content gives the rock a unique orange-red hue, which is particularly spectacular at dawn and sunset when the rock changes hue.

The rock changes colour at sunrise and sunset
Uluru, also known as Ayers Rock, is a large sandstone monolith that rises abruptly from the flat plains of spinifex grass in the Northern Territory of central Australia. It is sacred to the local Pitjantjatjara Aboriginal tribe, who own and administer the land on which the rock stands. The Aborigines attach spiritual significance to the site and request that visitors do not climb it.
The rock is composed of arkose, a coarse-grained sandstone rich in the mineral feldspar. The sandy sediment that formed the arkose was eroded from high mountains composed largely of granite. The average composition of the arkose is approximately 50% feldspar, 25-35% quartz, and up to 25% of other rock fragments.
The rock's surface is made up of valleys, ridges, and caves, which were created through erosion over millions of years. The surface oxidation of its iron content gives the rock a striking orange-red hue. This oxidation turns what would otherwise be grey rock to a reddish colour. As a result of this reddish hue, Uluru is particularly impressive at sunrise and sunset when the rock changes colour spectacularly. The contrast of colours in the sky and on the rock itself creates a beautiful sight.
