A Navcam image from Sol 4006 shows the surroundings where the Pancam pair straddle the crater’s edge. The linear feature (arrow) is visible in the right-hand half of the image above, next to the rover wheel track.
At right is another false-color image showing one of the rocks from the Lindbergh mound. This rock, which appears to show wind-erosion effects, is different from the Roosevelt Field block noted in an earlier post.
Opportunity raw images, its latest mission status, a location map. and atmospheric opacity, known as tau.
