In this VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 11th, 2014, and during its 54.300th orbit around the Red Planet, we can see some of the gigantic Dunefield that is located near and all around the North Polar Cap of Mars. This specific portion of the aforementioned huge Dunfield is part of the North Polar Region known as Siton Undae.

This image (which is an Original Mars Odyssey Orbiter b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18260) 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.
