We launched a new initiative, directed by Mohsen Kamel and Ali Witsell, to explore the older layers of the Heit el-Ghurab (“Wall of theCrow,” HeG) site. In some areas we have seen an older, different layout below what we have so far mapped, which dates to Khafre and Menkaure. We believe that the older phase settlement and infrastructure, which was razed and rebuilt, served Khufu's building of the Great Pyramid (94 [PDF 1]).
