In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 21st, 2015, and during its 61.084th orbit around the Red Planet, we can see a (really small) portion of Granicus Valles.

This extremely complicated Channels' System - approx. 750 Km (such as about 465,75 miles) long - is located to the West of the huge Martian Volcano known as Elysium Mons and, most likely, it was created by both Lava and Water (Out) Flows that were related to the (likely truly powerful) activity of the Elysium Mons Volcanic Complex itself.

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 20098) 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.
