This image covers strata with interesting geometry exposed in a small crater in the large crater west of the proposed Mars Science Laboratory (MSL) ellipse.

Observations like this one are needed to determine regional stratigraphy. At high resolution, we are able to see thin beds and contacts. Additionally, obtaining another image to create a stereo pair is needed to make a digital terrain model, that will help get bed dip angles.

This caption is based on the original science rationale.
