The Meridiani Face on MarsAuthor(s): Greg Orme
The Meridian Face has some similar features to the Cydonia and Crowned Faces such as having a crown. It is similar to the Nefertiti formation in that it seems to be made of dark soil, dunes in this case. Some dark dune fields can migrate large distances in Meridiani Planum, others remain confined in larger craters perhaps by shielding them from the wind. This can allow for the formation to be very old and remain intact. The similarity between the Crowned Face in the King’s Valley Libya Montes and the Meridiani Face was originally shown with an overall. The implicit hypothesis was that a new overlay would match the two faces even more closely, this has been borne out with the Crowned Face HiRise image and the Meridiani Face CTX image.
