Figure 3- Tracks left behind by Opportunity rover

Fig. 3. Tracks left behind by the Opportunity rover trace the traverse made up and along the western rim of Endeavour crater late in the mission. The degraded Endeavour is older and pokes up through the surrounding plains and records a history of degradation early in the planet’s history that included erosion by running water.
