Great Sandy Scars

In a small corner of the vast Great Sandy Desert in Western Australia, large sand dunes—the only sand in this desert of scrub and rock—appear as lines stretching from left to right. The light-colored fan shapes are scars from wildfires.

Part of the US Geological Survey's "Earth as Art" collection of images taken by the Landsat 7 satellite.

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.
