In this truly interesting VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 24th, 2015, and during its 58.886th orbit around the Red Planet, you can see quite a lot of Dust Devil Tracks (one of the most common Aeolian Surface Features found on Mars) which are all located on the Surface of the Martian Region known as Sisyphi Planum.

Please, also notice the extremely - and, so far, unexplainable - high Albedo (---> Reflectivity) of the East-facing Inner Wall and Slope of the Unnamed impact Crater visible at the bottom left (Sx) of the frame, as well as the Unusually-looking Surface Features - which are also very well defined - that are located on its Southern Inner Rim, in between 6 and 7 o'clock.

This image (which is a crop taken out from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19453) 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.
