Zephyria Planum

Today's VIS image shows part of Zephyria Planum. Zephyria Planum is located south of Elysium Planitia. Long term winds have eroded the surface of Zephyria Planum (bottom half of image). Elysium Planitia covers the top half of the image. The surface contains what looks like plates of material separated by lighter toned regions. This morphology is common in southern Elysium Planitia and it has been suggested that the 'plates' were cooled lava carried along the top of a still molten volcanic flow.
