Rick Menges has drawn my attention to the Ahram Weekly version of the end of term report form Hawass on the digs in the Valley of the Kings.
In the western valley, known as the Wadi Al-Quroud, or "valley of the monkeys", where the tombs of Amenhotep III and Ay are both located, the mission has carried out excavation work in an attempt to find Queen Tiye's tomb.
Hawass said that Queen Tiye, the mother of Akhenaten, was the wife of Amenhotep III and possibly the sister of Ay. If she was buried in the Valley of the Kings, her tomb might have been carved out near that of her husband, and if Ay was in fact her brother it would be all the more appropriate for her tomb to be near his as well. "It will be interesting to see what excavations in this area will reveal," Hawass says.
