Australia - December 30th, 2011

The large, orange-red expanse in the upper left quadrant of this image is the Simpson Desert, a large area of dry, red sandy plain and dunes in Northern Territory, South Australia and Queensland in central Australia. It is the fourth largest Australian desert, with an area of 176,500 km² (68,100 sq mi).

Visible east of the desert is Australia’s Channel Country, a region of outback Australia located mostly in the state of Queensland but also in portions of South Australia, Northern Territory and New South Wales. The Channel Country features an arid landscape with a series of ancient flood plains from rivers which only flow intermittently. The numerous intertwined rivulets that cross the region cover 150,000 km². The principal rivers are Georgina River, Cooper Creek and the Diamantina River.

When there is sufficient rainfall in their catchment area these rivers flow into Lake Eyre, South Australia. Here, the land around the rivulets appears brown, indicating little water flowing through them and causing green vegetation to flourish, and Lake Eyre is mostly white, indicating that water has dried up and left salt flats exposed.

The paths of rivers in Australia’s Channel Country stand out as green and light tan lines against the surrounding rusty red landscape.

Channel Country is a region of outback Australia whose name comes from the numerous intertwined rivulets that cross the region, which cover 150,000 km².

It features an arid landscape with a series of ancient flood plains from rivers which only flow intermittently. The principal rivers are Georgina River, Cooper Creek and the Diamantina River.

Australia - September 20th, 2010

The green areas visible across the arid, reddish expansive of Australian terrain are the rivers and surrounding floodplains of  the nation’s Channel Country. When there is much precipitation, the often dry riverbeds swell with water. Here, the Georgina and Diamantina Rivers and Cooper Creek (left to right) can be observed.

Other interesting features include numerous salt flats, visible as white or cream-colored areas near the rivers. The red, sandy area along the left edge is the Simpson Desert, and in the bottom left corner is the ephemeral Lake Eyre, which changes in color from tan to green as one looks southward.

The rusty red sands of the Simpson Desert occupy a large expansive on the left side of this image of central Australia. As one moves southward, the sands gradually turn lighter in color, until they are almost white.

To the east of the desert lies Australia’s Channel Country, a series of ancient flood plains in a now arid area. In times of high precipitation, intermittent rivers such as the Georgina and Diamantina Rivers and Cooper Creek (left to right) fill with water. Here, the floodplains around these rivers appear green, particularly the one surrounding Cooper Creek.

The Simpson Desert appears rusty red to the north and more tan to the south in this image of parts of central Australia. With a surface area of around 176 500 square kilometers, it spreads across the states of the Northern Territory, South Australia and Queensland.

It is bounded to east by the Georgina and Diamantina Rivers. Here, these rivers and others in Australia’s Channel Country, an arid area marked by a series of ancient flood plains from rivers which only flow intermittently (right side of image).

When very heavy rainfall occurs over time, these rivers flow into  Lake Eyre, a great salt lake that generally remains dry. Here, the lake is greenish in color to the south and more tan to the north.
