The Chevron located on the north face of Khufu’s Pyramid: (a) Photo and (b) sketch of elevation view with location of IF profiles (orange lines) discussed in this article. The red and green dashed lines in (b) show the estimated cross-sections of the SP-NFC as they are reported in Procureur, Morishima et al.15 and Elkarmoty, Rupfle et al.14, respectively. The blue reflector shown in (b) represents the backwall of the Chevron blocks and is from a reconstructed depth slice image from GPR measurements (200 MHz antenna) reported in Elkarmoty, Rupfle et al.14.
