In this beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 3rd, 2016, and during its 63.071st orbit around the Red Planet, we can see an Unnamed (and probably Outflow) Channel that is located on the Northern Margin of the very old and dusty Martian Region known as Arabia Terra. As a matter of fact, numerous Channels can be found in this Region, all draining from the higher elevations of Arabia Terra, to the lower elevations of Acidalia Planitia.

This image (which is an Original Mars Odyssey Orbiter b/w and Map Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20614) 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.
