In this really suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 2nd, 2016, and during its 63.061st orbit around the Red Planet, we can see a small portion of a large - and still partially covered by Frost and Water Ice - Dunefield that is found near the North Polar Cap of Mars. This area is part of the Martian Sub-Region known as Hyperboreae Undae which, as you know, is located between Escorial Crater and the Margin of Chasma Boreale.

This image (which is a crop obtained from an Original Mars Odyssey Orbiter b/w and Map Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20611) 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.
