I was looking over some NASA photos controlled by University of Arizona when I discovered this face. The face itself looks to be a male with a tall long hat. This hat is the same style as the hat that Queen Nefertiti of Egypt has on her sculptured bust. So the hat must be a symbol of their powerful and respected position and the face was made in the hills because they wanted to commemorate a great leader, just as humans carved Mount Rushmore with the images of four faces of great US presidents.
