I agree that something gassy could very well be an artifact in the mars photo's.
The Bonneville crator images I studied when they first were released.
Buried somewhere here in the ATS copyrighted topics is a thread that I started with images indicating what I still believe to be gas plumes venting
out of the crator.
I think it is becoming more apparent that there may be a frozen sub layer beneath the surface of mars. As indicated, the atmosphere being soo low,
along with the radiant heating of the daylight, it could be possible that the warming of the soil by the suns energy could be taking ice immediately
to a gas state, and then it would dissipate into the atmosphere after working its way out of the soil.
I wonder if the crators created by impact could actually have brought the ice closer to the surface, thereby allowing a more rapid and pressurized
vaporization of the ice by the sun, producing a vent.
(I will have to search again for the link, but it is in this catagory somewhere, back several months)
