Yogi Rock

This portrait of Yogi Rock, a now famous boulder on Mars , was recorded on Sol 3 by the Imager for Mars Pathfinder ( IMP ). Big and friendly looking like its Earth cartoon namesake Yogi Bear, Yogi Rock is a prominent visible feature at the Pathfinder landing site . Yogi and surrounding soil are being examined close up by the Sojourner robot rover. Initial attempts to approach the rock and to place Sojourner's Alpha Proton X-ray Spectrometer against it have met with some minor, but not unusual, difficulties . It is speculated that the light colored “moat-like” terrain around Yogi is the result of the evaporation of surface water deposited by ancient floods.
