In this really, both clear and interesting, VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 18th, 2015, and during its 61.049th orbit around the Red Planet, we can see a number of Unnamed (inverted?) Channels (as well as some truly small Buttes and Impact Craters) located on the North/Eastern Margin (---> Edge) of the Martian Region known as Terra Sabaea.
Latitude (centered): 33,5036° North

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 20097) has been additionally processed, magnified to aid the visibility of the details, extra-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.
