As part of its investigation of "Victoria Crater," NASA's Mars Exploration Rover Opportunity examined a section of the scalloped rim called "Bottomless Bay" (or "Bahia sin Fondo"). This view shows the northeastern side of Bottomless Bay as seen from the southwest. The exposures combined into this mosaic were taken by the rover's panoramic camera through a 750-nanometer filter during the 1,019th Martian day, or sol, of Opportunity's Mars-surface mission (Dec. 5, 2006). Contrast has been altered to improve the visibility of details in shadowed areas.
