JB: It's not my impression these days that the "single, long ramp" is universally championed by that many published authors.
Who do you mean by "Orthodoxy"?
SC: By 'orthodoxy' I mean those writers who have propagated this idea in the past. Surely a simple examination of the terrain would have told such people that a long, straight-on ramp was not feasible. And I refer also to those remaining authors who continue to even present it a possibility. This type of ramp is simply NOT possible for the construction of G1 as a cursory glance of the terrain would tell anyone. Even Hawass once upon a time promoted the idea of a long, straight-on ramp when he - of all people - should have known better. I am not saying Hawass is all-knowing but he most assuredly knows the terrain around Giza better than most.
If Egyptologists are to hold onto the ramp theory for G1 then they must start considering more seriously OTHER types of ramp e.g. the internal ramp hypothesised by Houdin. The straight-on ramp idea is dead and buried.
