text: Similar to the "Face", places on Earth are nature-made. Even though sand dunes on beaches are kept by humans, they were first nature-made. Sand storms on Earth create higher dunes in deserts because the starting dune blocks the sand from getting across it. This may be what caused the "Face" to be created. There may have been an oval shaped dune at that spot, and, then, a "storm" passed by. The beginning dune blocked the Mars sand from exceeding that barrier, and the "Face" we see now was created. The shadows forming the eyes, nose and mouth were created on accident.
