Cover image expansion

COVER Part of the exposed western scarp at Erebus crater, within Meridiani Planum, Mars, showing tilted, stratified bedrock 1 to 2 m thick. These rocks contain textures indicative of sedimentary processes, as described on page 1403. The image was acquired by the Pancam instrument onboard the Mars Exploration Rover Opportunity on 2 March 2006; this false-color composite was generated from Pancam's 750-, 530-, and 430-nm filters.
