In this great VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 23rd, 2006, and during its 19.321st orbit around the Red Planet, we can see a medium-sized Unnamed - partially Terraced and with a relatively large and uneven in shape, Pedestal - Impact Crater that is located in the Martian Region known as Acidalia Planitia. The "dark gray" Material visible in the centre of the Crater is, most likely, Basaltic Sand.

This image (which is an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20231) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced an sharpened, Gamma corrected and then re-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.
