The Finke River, or Larapinta in the Indigenous Arrernte language, is a river in central Australia, whose bed courses through the Northern Territory and the state of South Australia. It is one of the four main rivers of Lake Eyre Basin and is thought to be the oldest riverbed in the world. It flows for only a few days a year. When this happens, its water usually disappears into the sands of the Simpson Desert, rarely if ever reaching Lake Eyre.
Geography
The source of the Finke River is in the Northern Territory's MacDonnell Ranges, which flows through central Australia. The name is first applied at the confluence of the Davenport and Ormiston Creeks, just north of Mount Zeil.[2] From here, the river meanders for about 600 km (370 mi) to the western edge of the Simpson Desert in northern South Australia.[3] It flows through the West MacDonnell and Finke Gorge National Parks.[citation needed]
Usually the river is a string of waterholes, but it can become a raging torrent during rare flood events, fed by tropical rains upstream. In extreme instances, water from the Finke River flows into the Macumba River, which empties into Lake Eyre – a total distance from headwater streams of about 750 km (470 mi). Major tributaries include Ellery Creek, and the Palmer and Hugh Rivers.[citation needed]
After several bridges on the now-closed Central Australia Railway were washed away by floods, rails were laid permanently on the bed of the river. In February 1953, after two days waiting at Finke township nearby, the river level was low enough for a steam-hauled train – The Ghan – to proceed slowly across.[citation needed]
The Aboriginal name for the river in parts of the Northern Territory, usually taken as Larapinta, may have been incorrectly translated by its first transcriber, the explorer Ernest Giles. In August 1872, while camped at Charlotte Waters Telegraph Station, Giles was the first "outsider" to record the Arrernte name for the Finke River. He incorrectly deduced from his conversations with Southern Arrernte that the name was derived from the gigantic mythological snake (known as the Rainbow Serpent) which was believed to have created the river, and thought that larapinta meant snake in the local language. However in July 1876, Rev. Georg A. Heidenreich, the Superintendent of the Finke River Mission Station (Hermannsburg),[6][7] appears to have been the first to have confirmed the Western Arrernte name of the river, which was actually "Lara Beinta", which means "Salt River". This translation is now widely accepted because the Finke contains certain waterholes that are constantly salty (one of which is named "Salt Hole" in English). The legend of its derivation from the serpent is nonetheless held by the local people.[8]
It is not possible to say with absolute confidence that it is the very oldest river, but it is certainly one of the oldest rivers in the world.[16] However, southern parts of its course must be much younger, because the areas where the Finke now flows near the southern edge of the Northern Territory, and further south, were under the sea during the Mesozoic Era,[14] part of the Great Artesian Basin.
The antiquity of the Finke River is not unique, but applies equally to other large mountain-sourced river systems in central Australia, such as the Todd and Hale Rivers and many others, because most of the central Australian mountain belts formed at around the same time.[17] There are other eroded mountain ranges of equal or greater age to the MacDonnell Ranges, both in Australia and on other continents, so present rivers in those areas may have evolved from ancestral streams of equal or greater antiquity than the Finke.[citation needed]
TV series
The 2023 six-part documentary series Larapinta looks at the people, stories, and science of the Finke River. Created by Arrernte and Luritja woman Talia Liddle, the series features historians, scientists, and traditional owners, who share their stories and knowledge. Songlines and stories from The Dreaming add to academic data about the river and surrounds. Cinematography is by Torstein Dyrting. The series aired on NITV from 19 August 2023, as well as being available on SBS On Demand.[18][19]
