Comment: All flow features prefer the same general direction. It could be related to the unknown local topography. But the wide angle of direction, up to 180°  and upslope a crater rim, points to wind as the main modulator. The classical interpretation is that 'muddy' craters are an impact phenomenon. But this gets challanged by the large amount of material involved in the presence of evaporites at craters elsewhere.

Comment: Ouside ridges cross craters and generate large evaporites inside. More in left then in right part of crater. Indication of source flow deep below what created ridge?

Comment: Evaporite ridges L1-3 grown from the rim of a depression. The depression is probably not the remains of an impact crater row  but  of vulcanic related origine.

Comment: Like the above structure but less eroded. To the left two domes, probably hollow and three collapsed domes to the right. These domes were created by an upward movement of steam or water supported by subsurface volcanism, a process similar to but less violent than the creation of pseudocraters. In the craters or inside the domes could be an entrance to the subsurface world of Mars.

Comment: Two parts of evaporite covered rim are the only remains of a crater. Recent evaporite smooth, most area rough. No wind features. Perhaps area quite old and main errosion of evaporites by ice cracks during night cooling down to dust size.
