Larry Pahl, Director of the American Institute for Pyramid Research, presented a session on "Markings on the East Side Bedrock of the Great Pyramid" at The American Research Center in Egypt (ARCE) (www.arce.org) 2020 Annual Meeting. Many of the finds presented were first time discoveries.
Pahl demonstrates that a series of 5 pavement markers point directly to significant parts of the Great Pyramid, and seem to be coding other information. AIP is working at deciphering this code.
Pahl also identifies a template in the Great Pyramid at the level of the notch on the Northeast edge, that is of similar base size to the pyramid of Menkaure. It also bears a decided relationship to the tomb of the architect of the Great Pyramid, Hemiunu, which is in the west field of Khufu tombs.
