Comment: The dark area from the center to 10 o'clock position is either the shadow of an unusual peak hill or a black streak. If it is the latter, the crossing of surface obstacles would indicate airborne transport. (200% magnification)

Class: u

Comment: A crater atop an irregular dome with a dark outflow streak to the right. The streak crosses a depression, indicating airborne transport. The end of the streak down the cliff seems to be a very small ridge. Probably created by evaporite like the whole structure.

Class: s X

Comment: Black streak from source S atop a cliff down along distinct local topography, therefore flow with low momentum. Note end of dark flow E1 similar like small ridge E2 below. Perhaps E2 is evaporite and created by outflow like E1.

Comment: From same image like above. At S1 and S2 the end of black streaks probably originating from atop the bright cliff. At S3 a streak ends originating from S. S itself looks like an evaporite pyramid. A larger evaporite (or mud/debris?) area ends at A but originates from S too. Perhaps created by flow like S-S3.

Class: s
Source: SP123303
Comment: Black streaks S1 and S2 exhibit contractions in flow path, path probably carved out from flow. The feature is in contradiction to the dust avalanche theory, where carving is much less likely or even impossible.

Class: s
Source: SP124205
Comment: Contraction of black streak by local topography supports liquid flow theory. In this situation, a dust avalance would be expected to be less sharp and shorter.

Comment: Mid-part of streak is darker than the rest. Photometric effect of topography less likely regarding flow/topography relation. Perhaps here the cause of the black color (water) stayed longer and kept the color longer than eleswhere in the streak.

Comment: Black streak from narrow ridge ends before entering area of same dark color. It is unclear whether the dark area below is just the shadow of another ridge or chemically related to the streak. There is a similar problem in sp253704 below. If there is no shadow near the surface, water or remain of temporary lake seems possible.
