The focus of this image is on the western end of a fan-shaped landform, located at the end point of a sinuous valley.
Our observation covers crater-retaining mesas which overlie light-toned materials, both potentially related to the formation of the fan. There are also craters younger than the fan which impacted into these materials.
This caption is based on the original science rationale.
