This is a false color image of Sojourner rover next to the rock, Yogi. The red arrow indicates rounded rocks likely shaped by water. Barnacle Bill and Cradle (blue arrows) represent unweathered rocks. These rocks have sharp edges and points and may have been created through volcanic activity or as the result of an impact. The inset shows the rock Ginger where blue indicates unweathered rock. The origin of the rock is uncertain and Ginger was a target of future studies. Soils, which are heavily weathered, appear green and in flesh tones.
