This black and white image of Mermaid Dune was extracted from the green color plane of Sojourner's rear color camera. The rover right rear wheel is seen at bottom left and the shadow of the Alpha Proton X-ray Spectrometer (APXS) is at bottom center. The dune surface occupies the upper right half of the image. The contact between Mermaid and the underlying ground surface extends from the upper left to the APXS shadow. The surface of the dune exhibits a granular texture. The image resolution is about 1 mm/pixel, so the granularity may represent sand particles or cohesive clods of dust.
