This looks like a shadow in the image but there are physical features in the picture itself. So what's causing the shadow? You can find the image in the middle of the image near the right centre of it.

Hi, Shino

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.

It's the shadow of the cliff face itself. The sun is at 37ยบ degrees above the horizon at the left of the frame. Look at the top of the image, you can see where the shadow begins.
