In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 9th, 2014, and during its 56.124th orbit around the Red Planet, we can see, on the very  top portion of the frame, many (relatively small and highly irregular in shape) Hills and Ridges that belong to a (somehow Chaotic and extremely Dusty) Region known as Nilus Mensae, which is part - on its side - of the Complex Kasei Valles Channels' System.

Deep signs of (probably) Tectonic Activity which caused Fractures of the Terrain, as well as clear evidence of a powerful Wind Action that, in eons, eroded most of the Surface, are visible all over the Southern portion of imaged landscape and, just out of curiosity, even this area of Mars, as you can see, shows a very poor amount of, basically, small and medium-sized Impact Craters.

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 18700) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, 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.
