WATER POURED OUT of the mouth of Uzboi Vallis (center) into Holden Crater through its southern rim. The water laid down layers of sediments inside Holden. One possible landing site for the Mars Science Laboratory rover is the flat, smooth area at right center, close to where the channel cuts through the rim. This view looks toward the southwest.
