    Periodic Layering in Martian Sedimentary Rocks, Oblique View

    This oblique view of periodic layering in Martian sedimentary layers was derived from three-dimensional modeling based on a stereo pair of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
