Dry Lake Moore and Salt Flats, Australia29.7S 117.5E
The bed of Lake Moore (greyish in color, in the right half of the image) covers a great expanse of the Australian Outback, its dryness spreading over 140 km of the country. A series of white salt flats is visible east of the lake.
In an earlier geological period Lake Moore was full with water. Some speculate that global warming caused it to dry up, although the exact cause of the shift to its current arid state are unknown.
