Valley of the Kings the actual tomb of Tutankhamun (KV62) in November 1922. Various expeditions have continued to explore the valley, adding greatly to the knowledge of the area. In 2001 the Theban Mapping Project designed new signs for the tombs, providing information and plans of the open tombs. The earliest tombs were located in cliffs at the top of scree slopes, under storm-fed waterfalls (KV34 and KV43). As these locations were filled, burials descended to the valley floor, gradually moving back up the slopes as the valley bottom filled with debris. This explains the location of the tombs KV62 and KV63 buried in
Minor tombs in the Valley of the Kings had been intended to contain a human burial or not: KV50 contained fragmentary remains of a wooden coffin and KV52 an empty canopic chest. KV51 contained material which was dated to the Eighteenth dynasty, a dating which is ascribed to all three of these closely related tombs. It has also been suggested (although there is no real evidence to support this theory) that the animals interred here were a king's pets and that, given the proximity of his tomb (KV35), this king might have been Amenhotep II. KV53 is located north of KV29. It was discovered by Ayrton in 1905
