The objective of this observation is to examine a light-toned deposit in a region of what is called “chaotic terrain.”

There are indications of layers in the image. Some shapes suggest erosion by a fluid moving north and south. The top of the light-toned deposit appears rough, in contrast to the smoothness of its surroundings.

This area is also in a Context Camera image (P04_002536_1757).

This caption is based on the original science rationale.
