Australia - March 5th, 2010

The brown Flinders Ranges lie between the greyish white Lake Torrens (left) and Lake Frome (right). They comprise the largest mountain range in South Australia, which starts approximately 200 km north west of Adelaide.

Lake Torrens is a 5,700 square kilometre endorheic saline rift lake in South Australia. It forms part of the same rift valley that includes Spencer Gulf to the south and is approximately 240 km long. Lake Torrens is usually a dry salt flat. It has only been filled with water once in the past 150 years.

Lake Frome is a large endorheic lake in South Australia, east of the Northern Flinders Ranges. It is a large, shallow, unvegetated playa or saltpan, 100 km long and 40km wide, lying mostly below sea level and having a total surface area of 259,615 hectares. It only rarely fills with brackish water flowing down usually dry creeks in the Northern Flinders Ranges from the west, or exceptional flows down the Strzelecki Creek from the north.

Flinders Ranges: South Australia’s Largest Mountains

This swirled, almost paisley, brown design over Australia’s red terrain is actually a series of mountains known as the Flinders Ranges.

They are South Australia’s largest mountain range, situated approximately 400 km north of Adelaide. The discontinuous ranges stretch for over 430 km from Port Pirie to Lake Callabonna.

The interesting pattern visible from space was caused by sediments deposited in a large basin that the folded and faulted over time, creating the ranges. Today, these ranges are relatively low, due to erosion.

Two salt lakes, which are usually dry salt pans, are also visible near the ranges: Lake Torrens, to the west, and Lake Frome, to the east.

The interesting pattern of swirling brown lines between two white salt flats is actually a mountain range: the Flinders Ranges, the largest mountain range in South Australia.

The Flinders Ranges start approximately 200 km north west of Adelaide. They are discontinuous, and stretch for over 430 km from Port Pirie to Lake Callabonna.

The Flinders Ranges are largely composed of folded and faulted sediments of the Adelaide Geosyncline. This very thick sequence of sediments were deposited in a large basin during the Neoproterozoic on the passive margin of the ancient continent of Rodinia.

During the Cambrian, approximately 540 million years ago, the area underwent the Delamerian orogeny where the geosynclinal sequence was folded and faulted into a large mountain range. Since this time the area has undergone erosion resulting in the relatively low ranges today.

The lake to the west of the ranges is Lake Torrens, a 5,700 square kilometre endorheic saline rift lake. Lake Torrens is usually a dry salt flat. It has only been filled with water once in the past 150 years.

Lake Frome, also a large endorheic lake,to the east of the ranges, has similar characteristics. It is a shallow, unvegetated playa or saltpan, 100 km long and 40km wide, lying mostly below sea level and having a total surface area of 259,615 hectares. It only rarely fills with brackish water flowing down usually dry creeks in the Northern Flinders Ranges from the west, or exceptional flows down the Strzelecki Creek from the north.

Arid Landscape of South Australia

Australia - March 13th, 2009

South Australia is a state of Australia in the southern central part of the country, covering some of the most arid parts of the continent. With a total land area of 983,482 square kilometres (379,725 sq mi), it is the fourth largest of Australia’s six states and two territories.

It is bordered to the west by Western Australia, to the north by the Northern Territory and Queensland, to the east by Queensland, New South Wales and Victoria, and along the south by the Great Australian Bight and the Southern Ocean.

With nearly 1.6 million people, the state comprises less than 10% of the Australian population and ranks fifth in population among the states and territories.

The majority of its people reside in the state capital, Adelaide, visible here northwest of the green lake by the coast. Most of the remainder are settled in fertile areas along the south-eastern coast and River Murray.

The terrain consists largely of arid and semi-arid rangelands, evident from the red and orange tones of he landscape.

There are also several low mountain ranges in which the most important mountains are the Mt Lofty-Flinders Ranges system which extends north about 800 kilometres (497 mi) from Cape Jervis to the northern end of Lake Torrens and salt lakes, several of which can be seen in the upper half of the image.

The highest point in the state is not in those ranges, but Mount Woodroffe at 1,435 metres (4,708 ft) in the Musgrave Ranges in the extreme northwest of the state. The western portion of the state consists of the sparsely-inhabited Nullarbor Plain fronting the cliffs of the Great Australian Bight.

Southern Territory, Australia - January 14th, 2009

Most of the state of South Australia, in the southern central part of Australia, can be seen here.

The terrain consists largely of arid and semi-arid rangelands. There are also several low mountain ranges, of which the most important is the Mt Lofty-Flinders Ranges system  extending north about 800 kilometres (497 mi) from Cape Jervis to the northern end of Lake Torrens and the salt lakes.

The salt lakes are visible on the right, north of Spencer Gulf. The three most prominent ones are Lake Eyre (farthest north), Lake Torrens (just north of the gulf) and Lake Gairdner (farthest west).

The western portion of the state consists of the sparsely-inhabited Nullarbor Plain fronting the cliffs of the Great Australian Bight.
