In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 21st, 2014, and during its 54.071st orbit around the Red Planet, we can see a small portion of a complexly Faulted Region which is part of the Ceraunius Fossae, an area located to the South of the large Volcano knoen as Alba Mons. One relatively large Impact Crater (see the lower left - Sx - side of the frame), as well as a long and impressive Collapse Pit Chain (center and upper right - Dx - of the picture), jointly with several deep and wavy Faults (lower right - Dx - side and upper right side of the picture) that cut the larger - and lower - Collapse Pit Chain and which already project long and dark shadows, are also very well visible here. The Sun, already low on the Local Horizon, illuminates the scene from the West.

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 18203) 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.
