South Presso-Polar Pit Gullies (EDM - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

What is particularly interesting about these Gullies is that some might be forming (see this EDM, approx. 800 meters across, of the South-facing Gullies in the bottom Pit). The Gullies on this Wall have incised Alcoves, but only a few have well-developed Channels.

This could be a Region of current Gully formation. Aiding this hypothesis is the fact that there are a couple of depressions between the visible Gullies, suggestive of a developing Gully where water and/or material removed from under the Surface caused the overlying ground to collapse. It is also possible that water originating on the Surface is carving out these depressions, although it is difficult to melt water ice at the temperatures found in this particular location.
