Slope streaks in my opinion:
they are believed to be formed, basically, by small scale dry avalanches, but i've read also about other hypotheses, like geochemical weathering.
Another image that comes in mind is this one:
this is believed to be the possible result of the transit of a dust devil, because of the absence of any all around hill and because the dust devil
track (visible in the MOC image
does intersect with the apex of the streak.
But in my opinion, there's not an unique explanation for all these shadow-looking strikes.
And i guess that also NASA scientists have'n found everything about them.
Hope this helps mate.
