[Seeking the truth]

I remember reading years ago re: Egyptian pyramids, the blocks may have been poured in place rather like modern concrete.

My memory says that the Nile sediments can be used for this and that this process was "proven" in local testing.

I can not recall the source National Geographic? Smithsonian?

Have you ever heard of this explanation?

Ed Leedskalnin said he knew how the pyramids were constructed. His Coral Castle in South Florida has engineers just as baffled.

Yes. A Geologist wrote a very good book (now out of print) called "The Prymids". I can't remember the ISBN number but it concerns the use of a certain kind of sand located locally and an "atomic level" binding process. The process was chemical in nature and exothermic. He was able to replicate the creation of the kind of stone used using this process. Overall - pretty neat.

You have an excellent memory - that book was by a fellow named Davidovits, and I lent my copy to a friend (and lost it, naturally) - but I did finally track it down - it's The Pyramids, An Enigma Solved.

Well, you can't fault the fellow for self-confidence in the title! I would think, with my limited knowledge of materials technology, that it would be easy to tell if the blocks were cast in place or quarried from elsewhere, but I had a geologist friend cast some doubt on just how easy that would be or if that test had ever been made. I offer it without comment except that the world can be a very strange place...

There was an article last year about French scientists who made the "poured" block arguement too. I'll have to look around to see if I saved that one.
