Topographic map of Spirit's location at Troy This topographic map of Spirit's location at Troy represents low elevations in black, purple, and blue and high elevations in red. It was developed based upon Spirit's camera images of the location, taken before it got mired at Troy. The topographic model has had a regional slope removed, which reveals that Spirit's left wheels are sitting inside a subtle depression that the team has named Scamander crater. The right-side wheels are outside the depression. NASA / JPL-Caltech / Ohio State University
