This observation overlaps with another image we acquired in 2009. In Mars Year 30 (approximately February 2010 to January 2012) six images were taken here to monitor gully formation. We want to learn how the ripples have moved since then. Have they erased the newly-formed gullies? Are we seeing a competition between wind, ice, and water here?
