These features could also be mud flows, muddy terrains slowly creeping like glaciers. Do not forget that, if liquids cannot exist on the surface, they can exist underground, forming watertables and muddy layers. Only some metres of terrain are enough to provide the pressure necessary to maintain liquid water, and some metres more to maintain liquid carbon dioxid.

Also, as several already noted, the wandering of martian rotation axis may play an important role in Mars geology and climatology. Given the intensity of eolian erosion on Mars (able to invert features like large craters, implying an ablation of hundred of metres) we may wonder where all this dust goes. Logical reply: the dust is mixed with frozen ice in the polar cap. And when the rotation axis moves, it left glaciers, layered deposits, and the traces lake what is in discution in this thread. Very likely these linear deposits (together with the layered deposits) are made of loess, finely grained rock dust, which does not turn to earth like on Earth.
