In this suggestive and truly clear VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 5h, 2010, and during its 37.215th orbit around the Red Planet, we can see a small portion of the Floor of the extremely famous (for several reasons) Martian Impact Crater known as Schiaparelli Crater.
Generally speaking, smooth and rolling Terrain covers most of this portion of Schiaparelli Crater's Floor. However, since the Impact that created Schiaparelli Crater occurred billions of years ago, the Nature has had ample (---> a lot of) time to leave Lava and Sediments inside the Crater itself and then to slowly erode them.
The Ridge that is visible in the image's Southern End is part of an highly eroded Unnamed Impact Crater's Rim; just one of the many smaller Impact Craters that have been created (---> formed) on Schiaparelli Crater's Floor since it formed.

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 19800) 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 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.
