This image shows a southern mid-latitude crater: it has bright landslides on its southeast and west walls, some of which have noticeable boulder tracks where boulders rolled down the slopes.
The most noticeable features of this crater are the gullies on the north wall. A couple of small gullies appear to emanate from an overhang. The others originate at or near layers up-slope. The layers are sturdy and resistant from erosion: the layers that appear to be decaying into resolvable boulders, instead of particles easily moved by the wind, are evidence of this.
The enhanced color portion of this observation is spectacular. Note the distinct, blue layers lining the south rim of the crater and the white-blue rocks poking through. Wind erosion will likely expose them as time continues.
