The rock shown here was named Scooby Doo. It was a pink rock, which means it is probably coated with a crusty substance which contains a lot of rust. Its composition was very similar to the martian soils found at the site. This rock is similar to what was found at the Viking 2 landing site.
The action of the Rover's rear wheels was used to expose soil. Near Scooby Doo, the Rover could not dislodge any soil. Thus scientists labeled the soils near Scooby Doo as cemented soil.
