Far North (South Australia)
The Far North is a large region of South Australia close to the Northern Territory border. Colloquial usage of the term in South Australia refers to that part of South Australia north of a line roughly from Ceduna through Port Augusta to Broken Hill. The South Australian Government defines the Far North region similarly with the exception of the Maralinga Tjarutja Lands, the Yalata Aboriginal community and other unincorporated crown lands in the state's far west, which are officially considered part of the Eyre and Western region. The region is both the largest and also the least populated of the state. The Far North is also known as the ''Arid Lands'' of South Australia as much of the region is desert. Deserts The deserts in the north east are the Simpson Desert, Tirari Desert, Painted Desert and the Pedirka Desert. To the north and north west the Great Victoria Desert predominates the landscape. Governance The Far North includes the following local government areas: An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitjantjatjara People
The Pitjantjatjara (; or ) 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 (all are varieties of the Western Desert language). They refer to themselves as aṉangu (people). The Pitjantjatjara live mostly in the northwest of South Australia, extending across the border into the Northern Territory to just south of Lake Amadeus, and west a short distance into Western Australia. The land is an inseparable and important part of their identity, and every part of it is rich with stories and meaning to aṉangu. They have, for the most part, given up their nomadic hunting and gathering lifestyle but have retained their language and much of their culture in synergy with increasing influences from the broader Australian community. Today there are still about 4,000 aṉangu living scattered in small communities and outstations acros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fremantle, Western Australia
Fremantle () () is a port city in Western Australia, located at the mouth of the Swan River in the metropolitan area of Perth, the state capital. Fremantle Harbour serves as the port of Perth. The Western Australian vernacular diminutive for Fremantle is Freo. Prior to British settlement, the indigenous Noongar people inhabited the area for millennia, and knew it by the name of Walyalup ("place of the woylie")."(26/3/2018) Inaugural Woylie Festival starts tomorrow" fremantle.gov.au.

Tjukurpa
The Dreaming, also referred to as Dreamtime, is a term devised by early anthropologists to refer to a religio-cultural worldview attributed to Australian Aboriginal beliefs. It was originally used by Francis Gillen, quickly adopted by his colleague Baldwin Spencer and thereafter popularised by A. P. Elkin, who, however, later revised his views. The Dreaming is used to represent Aboriginal concepts of ''Everywhen'', during which the land was inhabited by ancestral figures, often of heroic proportions or with supernatural abilities. These figures were often distinct from gods, as they did not control the material world and were not worshipped but only revered. The concept of the Dreamtime has subsequently become widely adopted beyond its original Australian context and is now part of global popular culture. The term is based on a rendition of the Arandic word ''alcheringa'', used by the Aranda (Arunta, Arrernte) people of Central Australia, although it has been argued tha ...

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Salt Pan (geology)
Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals, usually shining white under the sun. They are found in deserts and are natural formations (unlike salt evaporation ponds, which are artificial). A salt pan forms by evaporation of a water pool, such as a lake or pond. This happens in climates where the rate of water evaporation exceeds the rate of that is, in a desert. If the water cannot drain into the ground, it remains on the surface until it evaporates, leaving behind minerals precipitated from the salt ions dissolved in the water. Over thousands of years, the minerals (usually salts) accumulate on the surface. These minerals reflect the sun's rays (through radiation) and often appear as white areas. Salt pans can be dangerous. The crust of salt can conceal a quagmire of mud that can engulf a truck. The Qattara Depression in the eastern Sahara Desert contains many such traps which served as strategic barriers during World ...

Oak Valley, South Australia
Oak Valley is the only community of Maralinga Tjarutja Aboriginal Council (AC) Local Government Area (LGA), South Australia. The population fluctuates, but a 2016 survey reported around 128 people, mostly Aboriginal. It is approximately NNW of the original Maralinga township, and lies at the southern edge of the Great Victoria Desert. It is named for the desert oaks that populate the vicinity of the community. It was established in 1984 with funds provided as compensation for the dispossession of the Maralinga people from their lands following the British nuclear tests which took place between 1956 and 1963. The risks associated with living in an area contaminated by plutonium, even after the cleanup have been a significant concern. In 2003 South Australian Premier Mike Rann and Education Minister Trish White opened a new school at Oak Valley, replacing what had been described as the "worst school in Australia". In May 2004, following the passage of special legislation, Prem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maralinga Tjarutja
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. The council was established by the ''Maralinga Tjarutja Land Rights Act 1984''. The area is one of the four regions of South Australia classified as an Aboriginal Council (AC) and not incorporated within a local government area. The Aboriginal Australian people whose historic rights over the area have been officially recognised belong to the southern branch of the Pitjantjatjara people. The land includes a large area of land contaminated by British nuclear testing in the 1950s, for which the inhabitants were eventually compensated in 1991. There is a community centre at Oak Valley, NW of Ceduna, and close historical and kinship links with the Yalata south, and the Pila Nguru centre of Tjuntjuntjara to their west.

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Carle Thulka
Carle Thulka, officially Carle Thulka / Lake Maurice is a salt lake in South Australia. It is the largest of many salt lakes in the eastern end of the Great Victoria Desert. It is normally dry, except during and after periods of heavy rainfall. When it is full, the lake covers an area of around . It is part of the geological basin known as the Officer Basin. The smaller Lake Dey Dey is to the north. Since 1985, Carle Thulka is part of the lands belonging to the Maralinga Tjarutja, a southern branch of the Pitjantjatjara. The community of Oak Valley is near the western shore of the lake. The exposed surface of the lake normally consists of dry clay, silt or sand, covered with a salty crust. The area around Carle Thulka is very dry. Two wells have been drilled to the southeast and northwest of Carle Thulka, to search for uranium and other minerals. Both wells yield very low levels of groundwater. The water contains high levels of salt. It has also been found to cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basin (geology)
In geology, a depression is a landform sunken or depressed below the surrounding area. Depressions form by various mechanisms. Types Erosion-related: * Blowout: a depression created by wind erosion typically in either a partially vegetated sand dune ecosystem or dry soils (such as a post-glacial loess environment). * Glacial valley: a depression carved by erosion by a glacier. * River valley: a depression carved by fluvial erosion by a river. * Area of subsidence caused by the collapse of an underlying structure, such as sinkholes in karst terrain. * Sink: an endorheic depression generally containing a persistent or intermittent (seasonal) lake, a salt flat (playa) or dry lake, or an ephemeral lake. * Panhole: a shallow depression or basin eroded into flat or gently sloping, cohesive rock.Twidale, C.R., and Bourne, J.A., 2018Rock basins (gnammas) revisited.''Géomorphologie: Relief, Processus, Environnement,'' Vol. 24, No. 2.
