This three-dimensional, cylindrical-perspective projection was assembled from images taken by the navigation camera on the Mars Exploration Rover Spirit on sol 110 (April 24, 2004) at a region dubbed "site 35." Spirit is sitting approximately 33 meters (100 feet) away from the northeast rim of "Missoula" crater.
