Astronomy Fun Fact:

Phobos, one of the moons of Mars, is so close to its parent planet that it could not be seen by an observer standing at either of Mars' poles. Phobos makes three complete orbits around Mars every day.

An excellent image of evidence of wind and water erosion on Mars. Thanks!

Would not a "slurry of CO2" ablate very rapidly from solid to gas in the thin Martian atmosphere? If so, there would be only a slight chance for channelized erosion of the soil and rock fragments on the surface of Mars, and thus reduce the probability that these channels were formed by CO2 flow.
