Originally posted by ArMaPI don't think so either, but the fact that they are near small jets made me think they are also CO2 releases but not as a jet, maybe because they are near the surface the CO2 is just released on that area.

* speaking of “salty“ - here are some very, very salty “blueberries“:

Ummm where did you get that the blueberries are very very salty?

The hematite in the Martian blueberries is solid evidence that they are, in fact, concretions. This alone would make a strong case for water, but then comes the clincher, the long-awaited spectrometer data from the RAT hole on El Capitan. The instruments say that the rock is as much as 40 percent sulfate salts

If you tasted this thing, you'd taste the salt. It's a very, very salt-rich rock. It looks like what geologists call an evaporite deposit. Evaporites form when you have liquid water, with lots of stuff dissolved in it, and the water evaporates away and it leaves stuff behind, so...salt flats. Go to the Great Salt Lake, go to any place where you've evaporated away seawater, and you will find these salt beds.

There's an awful lot of sulfate salt in this rock, and that's very, very hard to explain away other than water having been massively involved in creating this stuff.

One last piece of evidence would be familiar to anyone who's ever walked on the beach at low tide: ripples created by the flow of water over loose sand. Over long periods of time, rippled sediments can build up and harden into stone. The water is gone, but the ripples are still there in the layered rock at Meridiani.

Where the water came from is still unknown, but one possibility is that it came from below as groundwater, laced with sulfuric acid, percolating up through the volcanic bedrock, leaching out elements like iron, creating a broth of dissolved salts.

At times the water would flood the surface, forming shallow lakes or seas that would last for a while and then evaporate, leaving a crust of the dissolved sulfate salts behind. This may have happened repeatedly, building up a thick deposit of salty rocks over time.

The hematite blueberries would have grown within these rocks while they were saturated with water. Now the water is gone and the rock is eroding away, leaving the harder berries behind.

Wind is not the only force,

I see dust devils like these all the time here in West Texas, but they don't scorch the soil.

Maybe you have better? I would really like to see them if you do.

Where did you get that? What made those tracks? Notice how uneven they are? Less like a rolling wheel, more like a walking automaton or robot.
