This view taken by the Imager for Mars Pathfinder (IMP) was taken on Sol 3. "Barnacle Bill," the small rock at left, and "Yogi," the large rock at upper right, have been examined by Sojourner's Alpha Proton X-Ray Spectrometer (APXS) instrument and the rover's cameras. Barnacle Bill has the chemical composition of an andesitic volcanic rock, but may have been produced by sedimentation processes or meteorite impact. The lander's rear ramp which Sojourner used to descend to the Martian surface is at lower left, and a portion of deflated airbag is at lower right.

Mars Pathfinder was developed and managed by the Jet Propulsion Laboratory (JPL) for the National Aeronautics and Space Administration. JPL is an operating division of the California Institute of Technology (Caltech). The IMP was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator.
