In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 22nd, 2014, and during its 54.084th orbit around the Red Planet, we can see a very small section of the Volcanic Fissure (or Trough) known as Cyane Fossae. This Feature which, as you can see, is fuily surrounded by Lava Flows (all belonging to the very extensive Tharsis' Lava Flows System) is located in the Diacria Quadrangle of Mars, and it is centered at approx. 32,57° North Latitude and 120,17° West Longitude.
Cyane Fossae is approx. 940 Km (such as about 583,74 miles) long, and its physical characteristics show that it is a basically Linear Fissure (with some Fractures, here and there along its path), with sharp Edges and very steep (---> almost vertical) Walls; just out of curiosity, Cyane Fossae was so named (just like many other Martian Locations) after a so-called "Classical Albedo Feature".
Latitude (centered): 25,2367° North
Longitude (centered): 307,4200° East
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 18218) 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.
