	Monitoring Sand Sheets and Dunes This kind of environment has been monitored by HiRISE since 2007 to look for movement in the ripples covering the dunes and sheets.

	The White Cliffs of “Rover” This image reminds us of the rugged and open terrain of a stark shore-line, perhaps of an island nation.
