Mars -- Geomorphic Features
Valles Marineris (the Grand Canal)
Details of the Valles Marineris. We see erosional escarpments, things that look like giant landslides, and indications of erosion by flowing water.
This animation of a flight through the Valles Marineris was produced from digital terrain models (based on photos).
Some areas have been found where large sand dune fields are migrating across the surface.
