Two ephemeral lakes are visible in this image of arid Western Australia. The larger of the two, Lake Disappointment, appears as a white salt flat near the center. The other, smaller body of water, Lake Dora is located to the North, occasionally fed by the Rudall River.

The surrounding desert terrain is part of the Great Sandy and Gibson Deserts. The Great Sandy Desert is a 360,000 km2 (140,000 sq mi) expanse in northwestern Australia. It is a flat area between the rocky ranges of the Pilbara and the Kimberley.

To the southeast is the Gibson Desert, which is about 155,000 square kilometres (60,000 square miles) in size. It lies between Lake Disappointment and Lake Macdonald along the Tropic of Capricorn. The Gibson bioregion includes extensive areas of undulating sand plains and dunefields, low rocky/gravelly ridges and substantial upland portions with a high degree of laterite formation.
