In this VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 3rd, 2014, and during its 54.574th orbit around the Red Planet, we can see a small portion of the Northern Flank of the Martian Volcano known as Hecates Tholus, which is located in the Northern part of the Elysium Volcanic Complex.

Several (and very narrow) Volcanic Channels are visible toward the South of the frame, jointly with a numebr of tiny Impact Craters that cover almost the whole scene; furthermore, an unusually-looking (very round and, most likely, relatively recent) Impact Crater, with a Volcanic Feature (a small Caldera maybe?) associated to it (at about 7 o'clock) is clearly visible in the upper portion of the image, on the right side - Dx/East.

This image (which is a crop taken from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18483) 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 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.
