In this VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 26th, 2014, and during its 55.224th orbit around the Red Planet, we can see another relatively large portion of the Layering (---> North Polar Layered Deposits - or "NPLD", for short) located near (and all around) the North Polar Cap.

The lack of Impact Craters, which, as you know, is a characteristic of these Polar Regions (as well as it is a reliable evidence of the - relative - age of a Region), proves, once again, that these Areas are, from a Geological point of view, quite "young" and therefore subject to (several) on-going Geophysical Processes (and, of course, Weather-related Processes) that make them change their visual appearance almost continuosly

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 18677) 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.
