This image was taken when the rover, Sojourner, was next to Poohbear (rock at left). The foreground soil contains a sorted mix of small rocks and clods. The area ahead of the rover is covered with a bright drift material. Soil experiments where the rover wheels dug in the soil revealed that the cloudy material exists underneath.
