HiRISE: Exposing the rock in impact craters
In this complex crater (about 44-kilometers in diameter), we see bedrock in several locations from different depths in the crust. The central uplift exposes large fragments of green-toned bedrock that possibly originated from several kilometers beneath the surface. To the … Continue reading

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
