Barnacle Bill

Barnacle Bill was the first rock to be explored by the Rover. It was found north by northwest of the Mars Pathfinder lander.

Barnacle Bill was a dark rock. It had many small holes over its surface (vesicles) but otherwise did not appear to be as eroded as other rocks at the site such as the Souffle rock. These features help scientists figure out where Barnacle Bill came from.
