HiPOD 13 Jan 2022: A Knobby Unit in a Degraded Crater
This observation targets light-toned knobby units located within a heavily degraded crater. This unit is superficially similar to others located within a paleolake basin in the Eridania region, which appear to be altered ashfall deposits that washed into the lake or hydrothermally altered basin floor deposits. The units here may be the result of a similar process.

I wonder if prevailing winds, over millennia, deliver the same effects on river-like features as does water. The deep red color could be a settling of a different size particle that happens to be more red than the average particles in the area.
