This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 2007 (September 15, 2009). This drive back toward the meteorite Block Island took Opportunity near some of her old tracks, which are in this image. Old tracks are good for observing changes due to wind.
Pancam's 753nm, 535nm, and 432nm filters were used in making this mosaic. Two versions are provided at full resolution: an approximate true color rendering, and a false color rendering which enhances the subtle color differences in the scene.
