"A discovery made in 2013 is therefore extraordinary. In a cave, 410 miles away from Giza, on a 4,600-year-old papyrus scroll, archaeologists found a written letter or report, referring to a shipload of rocks probably used for Khufu's pyramid. The papyrus, addressed to Ankh-haf, Khufu’s half-brother, describes the expedition of a 200-man crew to the limestone quarries near Tura, on the eastern shore of the Nile. After loading the blocks onto their ship, the expedition followed for ten miles the river Nile. Also, the Aswan granite and other rocks used for construction were always quarried near the Nile or near larger bodies of water, like lakes or the Red Sea. Unloaded in the harbor associated with the construction site, the blocks were pulled on ramps and sledges onto the Giza plateau. The papyrus not only confirms the geological research done, tracking the rock types used in the construction of the great pyramid to certain quarries, but also explains how ancient Egyptians managed to transport the blocks, even without the help of aliens."
