In this VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 28, 2013 and during its 50.448th orbit around the Red Planet, we can see a few so-called "Linear Ridges" which are located near the South Polar Ice Cap. It may be interesting to notice and remind you that these kind of Linear Surface Features, in general (and the ones located near the South Pole of Mars, in particular), have been, for many years, mistakenly interpreted as "Clear Signs of Civilazations" (---> the "Walls" of an ancient "Inca-like City", to be more specific). As a matter of fact, this theory belongs to a number of "Legends" about the ancient past of Red Planet that we, as IPF, do not - honestly - believe that need or deserve any further investigation.

This frame (which is a crop obtained from an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17326) has been additionally processed, magnified, contrast enhanced 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.
