There is an anomaly on the Giza Plateau, in a symmetrical position to the Sphinx, that is the exact size of the Sphinx. It could be a "buried" second Sphinx. Besides the "hill" pictured in this satellite image, radar from GPMP confirms the same thing. Staring at the excavation reports of the Western Cemetary, it looks like they skipped this section. Looking at photographs of the area, I see nothing, even though you can see something on the satellite image. Any thoughts?
