Elongated Dunes
These lovely linear dunes at Meroe Patera identified in Context Camera images that have developed in a sand starved region of the dune field, elongating from behind a cliff.
Wind Carved Rock
The distinctively fluted surface and elongated hills in this image in Medusae Fossae are caused by wind erosion of a soft fine-grained rock.
Ancient Rivers
Billions of years ago, a river flowed across this scene in Mawrth Vallis. Like on Earth, these river beds can get filled up with rocks that are cemented together.
Active High-Latitude Dune-Gullies
Gully and defrosting activity have been visible here along the edge of a dune field, along with blocks of frost.
