Layered Sediments in the Medusae Fossae Formation

These very regular (stair-step) layers may reflect periodic climate change on Mars. We acquire stereo images and produce digital terrain models to better interpret the geologic processes that formed the layers. For example, if formed in lakes the layers should be nearly horizontal, but if the materials rained down from volcanic eruptions then the layers would mantle pre-existing topography.
