This portion of the "monster panorama" shows some of the unofficial names that have been applied to rocks at the Pathfinder landing site. Barnacle Bill, Yogi, Scooby Doo, and Lamb have been investigated by the Sojourner rover and its Alpha Proton X-Ray Spectrometer. Couch is a large rock on the horizon. The names are used by the Pathfinder team to help identify and keep track of the many rocks at the landing site.
