Couch Rock - Sol 3

Original caption:"This new view of the rock dubbed "Couch" was taken by the deployed Imager for Mars Pathfinder (IMP) on Sol 3.
Earlier images, taken by the undeployed IMP, hinted that Couch was balanced upon the rectangular rock approximately three-quarters of the way up from the bottom of the image. The deployed IMP, standing 1,8 meters above the Martian surface, has now revealed Couch to be a free-standing object positioned at the Martian horizon".
