Lake Eyre

Do you see a scary face looking back at you? The hollow-appearing eyes, narrow nose, and slash of a mouth are inundated patches of shallow Lake Eyre (pronounced "air"). Deep in the desert country of northern South Australia, Lake Eyre is an ephemeral feature of this flat, parched landscape. When seasonal rains are abundant, water fills the lakebed to some degree. During the last 150 years, Lake Eyre has filled completely only three times. When brimming, it is Australia's largest lake.

Part of the US Geological Survey's "Earth as Art 3" collection of images taken by the Landsat 5 and Landsat 7 satellites.

Since 1972, Landsat satellites have collected from space information about Earth’s continents and coastal areas, enabling scientists to study many aspects of the planet and to evaluate changes caused by both natural processes and human practices. This image was created by visualizing both visible-light and infrared data in colors visible to the human eye; band combinations and colors were chosen to optimize their dramatic appearance.
