The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area. The ejecta visible in this image seems to be lower than the surrounding surface.

This is unusual because impact ejecta is laid down on top of existing ground. The ejecta also seems to have pits. Perhaps the hot ejecta fell on frozen ground and melted the underlying ice?
