Salt Flats, Mountain Ranges and Gulfs in South Australia – April 18th, 2011

Australia - March 31st, 2011

Several salt lakes appear as white salt flats in this image of South Australia, the largest of which are Lake Gardner (left) and Lake Torrens (right). Also visible in the full image is Lake Frome, further east.

Running between Lakes Torrens and Frome are the Flinders Ranges, the largest mountain range in South Australia. The ranges appear here as a dark brown area.

South of the ranges and Lake Torrens is the Spencer Gulf, appearing green from sediments and algal growth. To the southeast of Spencer Gulf, in the full image, is Gulf St. Vincent.

Australia - June 1st, 2010

This image shows part of South Australia, near Adelaide. By the coast, the Yorke Peninsula separates two gulfs: Spencer Gulf on the west and Gulf St. Vincent on the east. The former is greenish in color from an outflow of sediments; fewer are present in the latter.

Inland, the terrain is greener and more fertile to the southeast, and more arid towards the north. The dark brown areas in the lower right quadrant are national parks and forest conversation areas. In the upper left quadrant, the lower reaches of the Flinders Ranges appear dark brown.

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.
