There are some interesting erosional signs in this observation, which will make for a good comparison with other intracrater fans and fluvial sedimentary landforms. We can also see an inverted channel ...

Long, amazing, Aeolis Serpens “fluvial ridge” intersects a crater rim in this observation. Was the crater buried and a stream flowed over it without any interaction (because it was buried), or does ...

A moderately eroded fluvial sinuous ridge (FSR), with lots of small craters in it, that stands out clearly above the surrounding material. To the north east it emerges from a small valley and becomes ...
