The collapse valleys in this portion of the floor of Bernard Crater were likely caused by the formation of Memnonia Fossae, a system of tectonic graben, that passes through the region. This image was captured by NASA's Mars Odyssey.

This observation from NASA's Mars Reconnaissance Orbiter covers a portion of the Martian equatorial plains called Elysium Planitia. In this location, lava that was once flowing across the surface interacted with multiple obstructions.

Dunes of sand-sized materials have been trapped on the floors of many Martian craters, as seen in this view captured by NASA's Mars Reconnaissance Orbiter. This is one example, from a crater in Noachis Terra, west of the giant Hellas impact basin.

This image from NASA's Mars Reconnaissance Orbiter shows the southern latitude Hale Crater, a rather large, pristine elliptical crater possessing sharp features, impact melt bodies ponded throughout the structure and few overprinting impact craters.
