Lake Dey Dey is one of many ephemeral salt lakes located in the eastern end of the Great Victoria Desert, in the Far North region of South Australia.
It is normally dry, except during and after periods of heavy rainfall. It is part of the geological basin known as the Officer Basin. The larger Carle Thulka is to the south. Since 1985, Lake Dey Dey is part of the lands belonging to the Maralinga Tjarutja, a southern branch of the Pitjantjatjara. [1] [2] The community of Oak Valley is located nearby to the southwest. [1]
The surface of the lake normally consists of dry clay, silt or sand, covered with a salty crust. [3] The area around Lake Dey Dey is extremely arid, and groundwater contains high levels of salinity. [4] The elevation of the surface above mean sea level is 208 m (682 ft). [5]
The lake is culturally important to the Maralinga Tjarutja people. [6] Both Dey Dey and Lake Maurice have Tjukurpa (Dreaming stories) associated with them, and access to some parts of Dey Dey is restricted to initiated individuals. [7] The major Tjukurpa associated with Lake Dey Dey relates to Wati Kulpirr, an ancestral spirit represented by the eastern grey kangaroo. [2]
An endorheic basin is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins or internal drainage systems or basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water.
The Amargosa River is an intermittent waterway, 185 miles (298 km) long, in southern Nevada and eastern California in the United States. It drains a high desert region, the Amargosa Valley in the Amargosa Desert northwest of Las Vegas, into the Mojave Desert, and finally into Death Valley where it disappears into the ground aquifer. Except for a small portion of its route in the Amargosa Canyon in California and a small portion at Beatty, Nevada, the river flows above ground only after a rare rainstorm washes the region. A 26-mile (42 km) stretch of the river between Shoshone and Dumont Dunes is protected as a National Wild and Scenic River. At the south end of Tecopa Valley the Amargosa River Natural Area protects the habitat.
Maralinga, in the remote western areas of South Australia, was the site, measuring about 3,300 square kilometres (1,300 sq mi) in area, of British nuclear tests in the mid-1950s.
The Gibson Desert is a large desert in Western Australia. and is still largely in an almost "pristine" state. It is about 155,000 square kilometres (60,000 sq mi) in size, making it the fifth largest desert in Australia, after the Great Victoria, Great Sandy, Tanami and Simpson deserts. The Gibson Desert is both an interim Australian bioregion and desert ecoregion.
The Pitjantjatjara are an Aboriginal people of the Central Australian desert near Uluru. They are closely related to the Yankunytjatjara and Ngaanyatjarra and their languages are, to a large extent, mutually intelligible.
The Pila Nguru, often referred to in English as the Spinifex people, are an Aboriginal Australian people of Western Australia, whose lands extend to the border with South Australia and to the north of the Nullarbor Plain. The centre of their homeland is in the Great Victoria Desert, at Tjuntjunjarra, some 700 kilometres (430 mi) east of Kalgoorlie, perhaps the remotest community in Australia. The Pila Nguru were the last Australian people to have dropped the complete trappings of their traditional lifestyle.
Aṉangu is the name used by members of several Aboriginal Australian groups, roughly approximate to the Western Desert cultural bloc, to describe themselves. The term, which embraces several distinct "tribes" or peoples, in particular the Ngaanyatjarra, Pitjantjatjara and Yankunytjatjara groups, is pronounced with the stress on the first syllable: [ˈaɳaŋʊ].
Mamungari Conservation Park is a protected area located in South Australia within the southern Great Victoria Desert and northern Nullarbor Plain about 200 kilometres west of Maralinga and 450 kilometres northwest of Ceduna. It is about 1,000 kilometres (620 mi) north-west of Adelaide and abuts the Western Australia border
The Maralinga Tjarutja, or Maralinga Tjarutja Council, is the corporation representing the traditional Anangu owners of the remote western areas of South Australia known as the Maralinga Tjarutja lands.

Acid sulfate soils are naturally occurring soils, sediments or organic substrates that are formed under waterlogged conditions. These soils contain iron sulfide minerals or their oxidation products. In an undisturbed state below the water table, acid sulfate soils are benign. However, if the soils are drained, excavated or exposed to air by a lowering of the water table, the sulfides react with oxygen to form sulfuric acid.
Allocasuarina decaisneana or desert oak is a medium-sized, slow-growing tree found in the dry desert regions of the Northern Territory, South Australia and Western Australia. The Anangu peoples know the tree as kurkara.
Indigenous land rights in Australia, also known as Aboriginal land rights in Australia, relate to the rights and interests in land of Aboriginal and Torres Strait Islander people in Australia, and the term may also include the struggle for those rights. Connection to the land and waters is vital in Australian Aboriginal culture and to that of Torres Strait Islander people, and there has been a long battle to gain legal and moral recognition of ownership of the lands and waters occupied by the many peoples prior to colonisation of Australia starting in 1788, and the annexation of the Torres Strait Islands by the colony of Queensland in the 1870s.
Tuyajto Lake is a salt lake located in the Antofagasta Region, northern Chile. Located at an elevation of about 4,010 metres (13,160 ft), its surface area presently fluctuates between 1.7–2.7 square kilometres (0.66–1.04 sq mi) but in the past it was considerably larger; this led to humans going to the lake and creating archeological sites there. Presently, the lake is groundwater-fed and has no surface outlet but water might seep out underground. It is part of the Los Flamencos Natural Reserve.
Archie Barton was an Aboriginal Australian political activist and land-rights campaigner. He played a key role in the 20-year campaign in the Maralinga Tjarutja people regaining ownership of their land, following the British nuclear tests at Maralinga, South Australia, and having the test sites cleaned up, and establishing Oak Valley with funds provided as compensation for the dispossession of the Maralinga people from their lands
The Serpentine Lakes is a chain of salt lakes in the Great Victoria Desert of Australia. It runs for almost 100 km (62 mi) along the border between South Australia and Western Australia. When full, the lakes cover an area of 9,700 hectares (97 km2). Most of it is located in the Mamungari Conservation Park. The Anne Beadell Highway crosses the northernmost arm of the lake.
