The flows seem to be partially filled-in, and there looks to be flow deposits at the base of the hill. Possible dunes adjacent?

I am curious about the dunes (?) in the featured image. Why that particular pattern? I am thinking that the surface of Mars is more ‘plastic’ than we have experience with.

Look at the previous streak tracks on either side of the long active streak – note how they swerve in response to hills in the pathway. So there’s clearly a deposit there, even if a thin one. And, near the center, notice the streak tracks in the same area as elongate ‘S’-shaped dunes (I think they’re dunes). Would be interesting to work out relative ages of streaks and dunes using classic geological principles. A lot going on in this image!
