Here’s a photo of the so-called “Bent” pyramid of Dahshur. The theory behind the bend is they started on too steep a slope to finish the pyramid and corrected themselves half way up. And the steep walls are also the reason the limestone is still on the outside and hasn’t been pilfered over the years for other buildings (like the original limestone exteriors of the pyramids of Giza).
I’ll post more photos of this and the red pyramid (and tell you why my legs and butt are sore today — and that I’m not alone). In the meantime, check out Marie‘s note about what we discovered deep inside the tomb chambers of the red pyramid and why our muscles are so sore today.
