In this extremely clear and suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on November, 17th, 2009, and during its 35.166th orbit around the Red Planet, we can see part of an ancient and highly degraded Hill which is surrounded (and, partly, covered) by many Unnamed Impact Craters - and one, visible in the lower portion of the frame, that is truly unusually-shaped. All these interesting Surface Reliefs are located in the Martian Region known as Tyrrhena Terra.

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 20428) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and 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.
