In this both suggestive and interesting VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 2nd, 2004, and during its 10.201st orbit around the Red Planet, we can see a small portion of the Martian Region known as Coprates Chasma (---> the "Coprates' Abyss"): a huge and (relatively) flat-floored Canyon, located in in the Coprates Quadrangle of Mars, and centered at 13,4° South Latitude and 61,4° West Longitude.

Coprates Chasma is part, as you should already know, of the Great Valles Marineris Canyon System; it is approx. 966 Km (such as about 599,886 miles) long and it was so named after a so-called "Classical Albedo Feature".

This image (which is an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19755) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then re-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.
