It’s not a conspiracy theory , 0’Kelly’s comment “ we found that quartz was thickest and most extensive In the area outside the tomb entrance and at each side of it . “ was not echoed in the reconstruction ,quite the opposite ,they avoided using any quartz at all . The same applies to what was appended to that comment, “and at each side of it that it decreased gradually in amount and extent until it virtually disappeared atK21 in the west and K 81 in the east “ That is not what we see in the reconstruction either.
The politics of the decision making might never be known , but there might be minutes from meetings yet to come to light from the archive .

Whatever was used as a revetment, if it was a revetment , obviously didn’t work, and what we see today is not representative as it excludes the " good quantity “ that “ was shattered and could not be used " That’s just O’Kelly’s comments not being followed through in the reconstruction .

There is still the major problem concerning the fact that the present wall is almost vertical and 3m high , I’d like to see that repeated experimentally with quartz blocks ,including the same type of quartz described by O’ Kelly that was dumped , without them being mortared to a concrete wall .

It’s nearly a decade since Gabriel Cooney’s “View from the platform “ ,hopefully there will be some new stuff . And there is also the Ann Lynch talk too

K81 is opposite GC -8, the same point at which the current Quartz wall fades out to nothing? Clearly seen here: http://www.newgrange.com/newgrange/newgrange_aerial.jpg

The other side was not excavated as far around so that is understandable.

On the smashed Quartz, O'Kelly only really refers to it relating to the 2m or so area that they cut into to carry out the experiment of tumbling a rebuilt wall, I don't think he says the smashed Quartz was typical of the entire spread.

I agree about the entrance, it's a shame they used limestone on either side but it was a case of damned if you do, damned if you don't. They needed to scoop out the area to install stairs and if he had faced this area with Quartz it would be an undeniable piece of fabricated reconstruction that critics would use as the stick to beat him with. He chose to be upfront and direct about it instead, using an alien stone source. I don't think he had much choice on whether stairs would be installed or not, that was one of the main aims before he even got the job.

I missed Ann Lynch's talk but I believe it was based on the Newgrange excavation report that is either just published or is imminent. Have you seen it? Very interesting and thorough.
