In this VIS image, taken by the NASA - Mars Odyssey Orbiter on July 8th, 2013, and during its 51.304th orbit around the Red Planet, we can see a portion of a huge and old Complex Impact Crater (on the Northern side of the frame), with a very small Dunefield near its Eastern Rim - at about 3 o'clock of the Floor - and other (at least) three more recent, small-sized Impact Craters, with one of them (the Southernmost) showing a large Dunefield (possibly, a Migrating one) on its Inner Northern Slopes, and several (again, most likely, Migrating) Dunes all around its circumference, with an higher concentration of them to its Eastern and Western sides.

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17424) has been additionally processed, magnified, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a 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.
