Looks Like The Driest Place On Mars Options

--- 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. ---

I am intrigued by the previous days image:

If you look closely on the left side there's a layer of what appear to be boulders partway down the slope. Is this common on Mars ?
My ancient fragmented memories of terrestrial geology associate this with glaciation. Am I way off base ?

If you speak of the boulders visible half-way of the gullies, I think that simply the gullies (and all the slope) were cut through several layers, one of these would give boulders and the others not. This, I think, has nothing to do with glaciations. (but the presence of gullies could).
