In this very suggestive VIS image, obtained by the NASA - Mars Odyssey Orbiter on January, 3rd, 2010, during its 35.733rd orbit around the Red Planet, we can see a small portion of Ophir Chasma (which is nothing else but a deep Canyon located in the Coprates Quadrangle of Mars, and centered at about South Latitude and 72,5° West Longitude). Ophir Chasma is approx. 317 Km (such as about 196,857 miles) long and it was so named after a so-called "Classical Albedo Feature".

Latitude (centered at approx.): 3,49485° South
Longitude (centered): 287,29100° East
Instrument: VIS

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 20592) 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.
