In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 15th, 2005, and during its 15.156th orbit around the Red Planet, we can see, once again, a small portion of the Martian Canyon - belonging to the Great Valles Marineris Canyon System - known as Candor Chasma (---> ChasmaAbyss).

The bright tones (---> colors) in this image (upper side of the frame) are the Canyon Northern (South-facing) Walls, while the dark gray and, somewhere, light gray and orangish Material (visible on the lower side of the frame), is just (Volcanic?) Sand and other Debris (mostly Rocks and semi-buried, or even partially unearthed Boulders) located on the Canyon's Floor.

A relatively small and old Impact Crater can be seen on the upper side of the Northern Wall of the Canyon. Just out of curiosity, the true nature of the "peak-like" and bright Features located at the base of the aforementioned Northern Wall of Candor Chasma is still a mistery.

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 20103) 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.
