The wadis which lie to the west of the main Theban mountain were last officially explored by Howard Carter in 1916 and 1917. He suggested in a subsequent article that these wadis might contain the burial ground of the XVIIIth dynasty royal family members whose burials were then missing. The granting of the concession to excavate the Valley of the Kings to the Earl of Carnarvon, and the subsequent discovery of the tomb of Tutankhamun, meant that Carter never returned to the Western Wadis to test his theory. The burials of many members of the XVIIIth dynasty royal family remain missing to this day. Since Carter’s exploration of this area the evidence in these wadis has been examined by many people, both officially and unofficially, but this report represents the results of the first Ministry of Antiquities-approved attempt to re-address Howard Carter’s hypothesis.
