The Opportunity rover took this mosaic at the edge of Endurance Crater on sol 101 (May 6, 2004). The greenish and blueish banding along the top of the left side of this mosaic is caused by the bright Martian sky saturating the green and blue filter images, and the saturated sky brightness "bleeding" down into the rest of the scene.
Two versions are available in full resolution: an approximate true color image made from Pancam's 432-nm, 535-nm and 753-nm filters, and a false color version which has been stretched to bring out the subtle color differences in the scene.
