Marathon Valley N Wall 4pos

        This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 4087 (July 24, 2015). The field of view is approximately 30 degrees featuring part of a crater wall located to the northwest of the rover. Pancam's 753nm, 535nm, and 432nm filters were used in this mosaic.  Three versions are provided at full resolution: an approximate true color rendering, a false color rendering which enhances the subtle color differences in the scene, and a stereo anaglyph for 3D viewing through red-blue glasses.
