In this VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 21st, 2014, and during its 55.154th orbit around the Red Planet, we can see a a large Dunefield (surrounded by Icy Plains and small Vertical Reliefs) that is located near the huge North Polar Dunefield - that we have seen in many other occasions on the APOD's pages - known as Olympia Undae.

This image (which is a crop taken from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18557) 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 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.
