Opportunity View of 'Lyell' Layer (False Color; credits: NASA/JPL-Caltech/Cornell University)

Caption NASA:"This view from NASA's Mars Exploration Rover Opportunity shows bedrock within a stratigraphic layer informally named "Lyell", which is the lowermost of three layers the Rover has examined at a bright band around the inside of Victoria Crater.

Opportunity used its Panoramic Camera (PanCam) to capture this image with low-Sun angle at a Mars Local Solar Time of 15:21, during the Rover's 1433rd Martian day, of Sol (Feb. 4, 2008).

This view combines separate images taken through the Pancam filters centered on wavelengths of 753, 535 and 432 nanometers.
It is presented in a false-color stretch to bring out subtle color differences in the scene".
