Famous pyramids in Sudan.  I forget the name of the pyramids or how old they are or where they're located.  I'm pretty sure that they're pyramids, though.  They certainly look like pyramids. 

You get a sense of how big those pyramids are by our lunch truck, parked off to the right, and the two lone figures walking in the desert.  (Cue "All Along the Watchtower.")  Interestingly enough, the view the other direction was of a lush and green river valley.  Seriously. 

I got so much sand in my shoes on the way down from this vista point that for a brief period I was actually classified as part of the Nubian Desert.
