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.

Dry Lakebed of Lake Barlee, Australia

The large, M-shaped greyish white area in the upper lefthand quadrant is Lake Barlee, an intermittent salt lake in Western Australia. The lake has a width of over 100 km from west to east, and a length of about 80 km from north to south.

Lake Barlee is usually dry, hence its grey and white tones tones in this image, created by salt in the lakebed. It fills about once every ten years, although these wet periods generally last less than a year.

Colors of Lake Mackay, Western Australia

Lake Mackay is one of hundreds of dry lakebeds scattered throughout Western Australia and the Northern Territory. In addition to the lake, the image also shows the dry appearance of Western Australia’s Great Sandy Desert, Gibson Desert, and Tanami Desert.

Lake Mackay measures approximately 60 miles (100 kilometers) east-west and north-south. The lake is the largest in Western Australia and has a surface area of 3,494 square kilometres (1,349 sq mi).

In this arid environment, salts and other minerals are carried to the surface through capillary action caused by evaporation, thereby producing the white reflective surface.

The darker, greyish areas of the lakebed are indicative of some form of desert vegetation or algae, some moisture within the soils of the dry lake, and the lowest elevations where pooling of water occurs.

The orange dots, on the other hand, are hills scattered across the eastern half of the lake and east-west-oriented sand ridges south of the lake.

North of the Himalayas, the lakes of Tibet’s fittingly named “Lakes Region” appear in various shapes and sizes. The two largest lakes visible here on the Tibetan Plateau are Siling Co (left) and Namtso (center).

Lake Namtso or Lake Nam, meaning heavenly lake, is a mountain lake just north of the Nyenchen Tanglha, or Nyainqêntanglha, a mountain range which lies approximately 300 kilometers northwest of Lhasa in central Tibet. The mountain range has more than thirty peaks over 6,000 metres high, and four are more than 7,000 metres high.

A peculiarity of Lake Namtso is that it is the highest salt lake in the world, lying at an elevation of 4,718 m. It is also the largest salt lake in the Tibet Autonomous Region of China, although it is not the largest salt lake on the Qinghai-Tibetan Plateau.

Sediments Along Northern Coastline of Western Australia

Rivers along the northern coastline of Western Australia release sediments into the Indian Ocean. The sediments appear most concentrated in King Sound, east of the Dampier Peninsula near the center of the image. The sediments are released into the sound by the Fitzroy River.

West of the peninsula, moving southwest down the coast, one comes across a long stretch of white sand beaches, the most popular of which is known as Eighty Mile Beach due to its length of 80 miles (130km).

Towards the bottom of the image another white line can be seen; this is the Rudall River, which connects to the seasonal salty Lake Dora. Another lake is visible near the right edge of the image, in the upper right corner: Lake Argyle, which is the second largest artificial lake in Australia by volume.
