--- This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows polygonally patterned ground on the floor of a trough in the southern hemisphere of Mars. The polygons could be an indicator that ground ice is or was present at this location. The dark streaks were formed by passing dust devils. ---

The gullies might be the product of the acumulation of humidity on sands caused by the transit evaporation of water from poles. Then, when the weigth of sand (gravity force) becomes greater than the friction and slope force, then the sand start to slid on some surface that has no humidity (the line between humidity and dry sand) and the other possiblity, as Richard, as said is about the layers of sedimentary of land. The harder ones is the last surface to be slide.
