Mawrth Vallis (3-D)

Mawrth Vallis is one of the oldest valleys on Mars, formed in and subsequently covered by layered rocks, which are now exposed due to erosion. Mars orbiters have observed clay minerals that form in water in and surrounding this valley, which made Mawrth Vallis one of the locations considered as a landing site for the Curiosity rover. Multiple impact craters within this image have been partially filled in by wind-blown sand.
