My speculation is that water must have etched out the gullies eons ago. Since they are too wide deep and extensive for it to have been anything other than water?Correct me if I'm wrong but I believe you are saying the CO2 answer is less plausible because the size of the gullies would require more continuous scouring than CO2 could provide. You are thinking that water could carry material farther. If so, how do you reconcile the fact that water can not exist on the surface because the pressure and temperature are both too low? I would grant small amounts of water could move small amounts of material before freezing or evaporating but this is the same theory that allows liquid CO2 to do the same thing.
