THE "STITCHES" AND THE "BONE"
Under the other mountain or "island" (it is very possible that the region around the "Face" used to be a sea or a lake) there is a strange formation that I will call "the bone" and below that a row of parallel lines, which I will call "the stitches". These stitches also appear at the base of the island.
Here is a close-up of this part. You can very clearly see there is a straight line composed of short black (originally white) stripes. There are about 20 of these stripes visible here. The fact that these stand out from the surrounding so clearly, even knowing that the light comes from a relatively high angle, means that either the depth of these things is rather markable (making strong shadows) or they actually ARE WHITE.
