In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on October, 14th, 2003, and during its 8.121st orbit around the Red Planet, we can see a few major (---> bigger) Unnamed Primary Impact Craters and a lot of small ones, which are all located in the Martian Southern Hemisphere's Region known as Terra Cimmeria.

Note: the bigger Unnamed Impact Crater visible here, in the lower portion of the frame, to the left - Sx - (once you consider and evaluate its truly unusually-looking - let's say, kind of "squared" - shape), might also (and well) be a Secondary Impact Crater.

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 19725) 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.
