Another dose of Martian awesome

Looks like Growth, maybe algae or small plants?

Here is the explanation.
It’s Mars, a dune field in the far north; at latitude 83.5° to be precise, less than 400 km (240 miles) from the north pole. The eternal Martian wind blows the heavy sand into dunes, and you can see the hummocks and ripples from this across the image. The sand on Mars is from basalt, which is a darkish gray color. The red comes from much smaller dust particles which settle everywhere.

But what are those weird tendril thingies?

In the Martian winter, carbon dioxide freezes out of the air (and you thought it was cold where you are). In the summer, that CO2 sublimates; that is, turns directly from a solid to a gas. When that happens the sand gets disturbed, and falls down the slopes in little channels, which spreads out when it hits the bottom. But this disturbs the red dust, too, which flows with the sand. When it’s all done, you get those feathery tendrils. Note that at the tendril tips, you see blotches of red;( that’s probably from the lighter dust billowing a bit before settling down.)
LOL PROBABLY ..
How do we (NASA? article doesn't say w/o digging deeper IDK) know this stuff is flowing downhill like that? Ah, because in this picture we’ve caught it in the act! In this image, a closeup of a region just to the left of center of the big image, you can actually see the cloud of dust from an avalanche as it occurs.

Good explanation ..or just another a cover up? lol

that is obvious vegetation, looks alot like dying or decaying trees on earth.

some of them it looks like if you zoom up on them it looks like arizona state tried to blend them in, but most of them are obvious sticking up vegetation.

excellent, thanks bro

How would they account for the "trees" that are leaning over. Some of them are curved and leaning.
Also, it looks like the color was added afterward . There is just too much blotching in both the red and the blue.
Those are trees...........
Awesome picture!
