In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 14, 2012, during its 47.318th orbit around the Red Planet, we can see an extremely complicated network of "arcuate" Fractures and Channels covering an area located on the South/Eastern Margin of the Martian Region known as Elysium Planitia. Notice, on the upper left corner of the frame, a Surface Relief that appears to be a so-called "Butte" (such as an isolated Hill with very steep sides and a Flat Top; in fact, it is a Surface Feature quite similar to - but narrower than - a so-called "Mesa"). Furthermore, in the upper left quadrant of the frame, at about 10 'o clock, the most attentive Readers should be able to spot a bizarre-looking Surface Feature which could either be representative of a couple of elogated Collapse Pits or, maybe, a Double Impact Crater.

This frame (which is a crop from an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 16329) has been additionally processed, magnified, contrast enhanced and then colorized in Absolute Natural Colors (such as the colors that a 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.
