A grayscale image from the Mars Global Surveyor shows a three-kilometer region in Schiaparelli Crater on Mars. The image depicts layered hills and wind-blown sand, creating formations that strikingly resemble a terrestrial coastline. Dark sand appears as “water” in the lower portion of the image. The layered sediments are believed to have formed through ancient deposits, potentially from water or wind, and have since been smoothed and eroded by wind and sandstorms.
