HiRISE: Cross-section of a complex crater
This image shows a cross-section of a complex crater in Terra Cimmeria. Starting in the center, we see a series of peaks with exposed bedrock. These peaks formed during the impact event when material that was originally several kilometers below … Continue reading

HiRISE: Tell-tale bedrock in Tyrrhena Terra
Large craters, like this 50-kilometer diameter one, can uplift material from below and form a mountain-like central peak. Craters of this size on Mars become unstable as they form and collapse due to gravity. Craters with central peaks and terraced … Continue reading

HiRISE: Youthful crater in Cydonia Colles region
The 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 … Continue reading
