Under the Sand (Original NASA/MGS/MSSS b/w Frame)

Caption NASA originale:"This MGS-MOC image shows a partially-buried crater in the North Polar Region of Mars.
The circular feature is surrounded and partly overlain by some of the many, many sand dunes in the area. The steepest slopes on each dune — their "slip faces" — face toward the SouthEast, indicating that the dominant winds responsible for sand transport in this Region come from the NorthWest".
