Thank you, and I took the time to speed read a part of that text you linked.

But you are absolutely right, I wrote about liquid CO2 in the first paragraph since that was what tuvas asked about.

But the following sentence lacks the word 'frozen' and should have read.
"I personally think frozen CO2 are a more likely explanation .......... at -78 °C."

(And for once I dont edit, since I got back to the subject so fast)

Finally I take the opportunity to link a text where the author points out that the gullies seems to appear on the slopes facing away from the sun. Something that again are one sign that we might not be seeing the activity of water here.

And then again another link to one text that also discuss the CO2 as one alternative explanation for the gullies. Liquid CO2, Not Water, Likely Created Martian Gullies
