Possible Shoreline in Southern Isidis Planitia

This area--known as the Deuteronilus contact of the Isidis Basin--has been interpreted as a possible ancient shoreline. There are also suggestions that this contact is of volcanic origin.

One direct benefit of a high resolution image is the ability to monitor the detailed morphology of the contact to help to determine whether this formation is the result of an ocean or of a volcanic filling of the Isidis Basin.
