The sedimentary history of Mars is important to understanding climate change and the evolution of Mars.

Sedimentary rocks consist of fine particles carried by the atmosphere and/or water and deposited in generally flat-lying layers, which become indurated (turn into rock) over time.

This image covers some steep slopes with good exposures of the bedrock layers, revealing diverse color and textures. A detailed study of many such exposures along with compositional data can be used to reconstruct the sequence of events and interpret the geologic history.

Sunken and Pitted Ejecta

The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area (north is up, west is to the left).

Secondary Craters

This image of a southern mid-latitude crater was intended to investigate the lineated material on the crater floor. At the higher resolution of HiRISE, the image reveals a landscape peppered by small impact craters.
