In this nice and interesting new VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 26th, 2015, and during its 58.911th orbit around the Red Planet, we can see countless Dust Devil Tracks (or "DDTs", for short) marking a "bumpy" portion of the Southern Martian Region known as in Noachis Terra. The Dark Tracks, if you pay attention to the details of the frame, clearly show where the Whirlwinds were in direct contact with the Surface and removed quite a lot of orange-colored Dust, thuso exposing the darker Rocky Surface of Mars.


Furthermore, on the very top part of of the picture (such as towards the North), you can also see a portion of the Southern Inner Rim of an Unnamed Impact Crater which is characterized by the presence of fresh, well defined and extremely deep Gullies.

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 19464) 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.
