HiRISE: Youthful crater in Cydonia Colles region

ESP_027417_2200The central portion of this image is dominated by a sharp-rimmed crater that is roughly 5 kilometers in diameter. On its slopes, gullies show young (i.e., geologically recent) headward erosion, which is the lengthening of the gully in the upslope direction.

This crater is also remarkable for another reason. This image is part of a stereo pair, and the anaglyph of these images shows that the bottom of the crater contains a small mound. This mound hints at a possible complex crater, with the mound being a central uplift. [More at link]
