In this very nice VIS image, taken by the NASA - Mars Odyssey Orbiter on January, 25th, 2016, and during its 62.620th orbit around the Red Planet, we can a few Dark Dunes (as a matter of fact, a tiny "Dunefield") located on the Floor, toward the South/West of the Complex Central Peak of this Unnamed Impact Crater found in the Martian Region known as Isidis Planitia.
Please notice that the tiny Dunefield clearly appears to be surrounded by a large area of Dark Dust-like Material, whose origin and nature are still unknown.

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 20450) has been additionally processed, magnified to aid the visibility of the details, extra-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.
