CAIRO, EGYPT—Live Science reports that experts are calling for more radar data and information on how it was collected to be released from the recent investigation of the area around Tutankhamun’s tomb. Earlier this month, Japanese radar technologist Hirokatsu Watanabe suggested that there could be two cavities beyond the walls of Tutankhamun’s burial chamber, and that those cavities could hold metallic and organic substances. Commenters have also noted that the geology of the Valley of the Kings contains many natural voids. “It does not appear that these GPR [ground-penetrating radar] data have been processed, or that any of the so-called anomalies are visible in the raw data that are provided,” said Lawrence Conyers of the University of Denver. Egypt’s Ministry of Antiquities has announced that additional radar surveys will be conducted over the next few days. To read more about Tutankhamun, go to "Warrior Tut."
