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, just beyond where the channel cuts through the rim. This rendering (vertical exaggeration about 2x) looks toward the southwest. It was created using data from various spacecraft. Credit: NASA/JPL/Arizona State University, R. Luk
