In this VIS image, taken by the NASA - Mars Odyssey Orbiter on January, 12th, 2015, and during its 58.026th orbit around the Red Planet, we can see a conspicuous number of (apparently) VERY fresh Gullies dissecting the Southern Portion of the Inner Rim of this Unnamed Impact Crater located in the Martian Region known as Terra Cimmeria. The Dark Dunefield which is well visible on the Northern Portion of the Crater might (in our opinion, as IPF) be Migrating outside the Crater's Floor (see the shape and direction of the Dunes to better understand this, however, simply pure speculation).

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19208) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
