Large impacts produce uplifted central structures, either peaks, or pits, or an uplifted peak with a central pit. This crater south of Aurorae Chaos has a central pit exposing bedrock units with diverse colors, indicating diverse rock compositions.

This crater includes clay-rich minerals identified by the CRISM instrument on MRO. See this enhanced-color cutout over the eastern half of the central pit.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 53.4 centimeters [21.0 inches] per pixel [with 2 x 2 binning]; objects on the order of 160 centimeters [63.0 inches] across are resolved.) North is up.
