Gullies Quotes
To see new gullies and other changes in Mars surface features on a time span of a few years presents us with a more active, dynamic planet than many suspected before Mars Global Surveyor got there.

If liquid water pops out onto Mars' surface, it can create short gullies about 550-yards (500-meters) long. We find that the short length of the gully features implies they did form under conditions similar to those on present-day Mars, with simultaneous freezing and rapid evaporation of nearly pure liquid water.
