ESP_015900_1465_RED_abrowse-00-PCF-LXTT.jpgUnnamed Southern Crater with Gullies, Rolling Boulders and Dunes (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)317 visiteCaption NASA:"Although this image was primarily taken to study the Gullies in the Inner Walls of the Crater, it also reveals a few other interesting things.
Near the Gullies in the Northern Wall of the Crater, for instance, some Boulders have bounced down the Slope, leaving trails of Hollows along their paths (see EDM n. 1).MareKromiumMar 03, 2011

Fienga - Lunexit Team)367 visiteCaption NASA:"This image shows a nice example of different types of Dunes in close proximity to each other: North is at roughly 03:00 in this EDM.
On either side of the Mound - which is located on the Southern End of the Crater Floor - there are different types of Dunes. On the Southern side of the mound (left side of the EDM), there are "Star Dunes" (named for the Star-like Intersections of their Crests). These types of Dunes are usually formed when the wind blows in multiple directions.
On the Northern side of the Mound (the right when looking at the EDM), there are simpler Dune shapes, forming roughly straight, parallel lines. Notice that the same side of each Dune is steeper. These are called Linear Dunes, and are formed by wind blowing mainly parallel to the direction of their Crests, probably with some variation to one side or the other that causes the asymmetrical Slopes. The Linear Dunes transition to the Star Dunes near the Mound.
Since the main factor controlling which type of Dunes are formed is the (Dominant) Winds' Direction, there must have been different Wind Directions in this area (for instance, it is very likely that significant whirlpools were caused by the wind blowing around the Mound or also when they interacted with the nearby Crater Wall).MareKromiumMar 03, 2011
