I actually didn't read the text on that prior to posting. Saw the image of the supposed "interior ramp" with the article and assumed the text would cover that. I had several years ago watched a documentary regarding some guy's theory on an interior ramp. I think the doc may have been NOVA, so it apparently wasn't some totally off-the-wall nonsense. I believe they may have actually found portions of what may be an interior ramp.
I first read the interior ramp theory back in the 1970s. That one has been floating around for a while along with the exterior ramp that wound around the pyramid.
There are issues with both including how they raised and mounted 70+ ton granite slabs over the King’s Chamber in the Great Pyramid and in the case of the Khafre pyramid how they raised the pyramidion.
