This image footprint is part of the massive ejecta blanket of Arandas Crater. The inner ejecta layer runs up against the rim of a pre-existing crater, and has produced several compressional ridges on the blanket. In addition, there are radial grooves that are typical of the inner layer of a double layer ejecta crater. This image will help resolve the timing of groove formation relative to the interaction of the ejecta layer and any obstacles.
