In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 18th, 2014, and during its 54.037th orbit around the Red Planet, we can part of an ancient (but VERY well preserved) sinuous Channel known as Buvinda Vallis (so named after a "classical river" found in Hibernia - the Latin name for Ireland -, and the present Boyne River). Buvinda Vallis (which is approx. 120 Km - such as about 74,52 miles - long) is located just outside the North/Eastern Flank of the Martian Volcano named Hecates Tholus.

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 18199) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced, 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.
