Martian Duneforms

There are many portions of surface near the Mars Pathfinder landing site covered by sand dunes, as shown in this picture. These dunes are created by saltation.

During the Rover's exploration of the Martian surface, it rolled over what scientists now call the "Mermaid Dune".

Analysis of the soils at Mermaid Dune, as well as study of other wind drifts seen near the landing site contributed to the overall understanding of the erosion of the surface of Mars.
