Gullies in a Crater in Noachis Terra
The gullies shown in this image are similar to terrestrial gullies produced by flowing water. The current Martian climate would not allow for liquid water to be stable at the surface for extended periods of time, though. These gullies could have formed under a different climate, or perhaps they were carved by short-lived streams; they could also have been produced by dry landslides.
Image cutout is less than 5 km (3 mi) across and the spacecraft altitude was 251 km (156 mi). For full observation details including images with scale bars, visit the source link.
