In this interesting and suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on October, 9th, 2002, and during its 3.635th orbit around the Red Planet, we can see a very small section (rich of an incredible variety of Surface Features) of the interior of Ganges Chasma (a very deep Canyon located at the Eastern End of the Great Valles Marineris Canyon System.
Ganges Chasma has been so named (quite obviously) after the River Ganges and it is thought, by several Planetary Scientists, to have formed through (---> because of) a series of Catastrophic Discharges of both Water and CO2 which were coming (---> actually, which were released, for still unknown reasons) from Lakes or Channels located inside/near Chaotic Terrains (such as the ones preserved in Ganges Chaos - Southern Margin of Ganges Chasma).
Can you identify at least three different (and yet vey common) Martian Surface Features that lay inside the Abyss (---> Chasma) of Ganges? Enjoy the research and Good Luck!...

This image (which is an Original Mars Odyssey Orbiter false colors and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19028) 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.
