I just had to take this photo of our glaciologist leaving Flats in Luxor about to go shopping. Yes I know he looks as thought he is about to attempt the Eiger. He said he didn't need his ice axe but had a snow shovel in his pack. We are not quite sure whether to believe him or not.
He is on a dig using the equipment they would normally use to investigate glaciers to investigate tombs, Fascinating stuff. So he can look down obviously but only a certain depth but also whilst in a burial chamber can look across to see if there is anything at the same level. I have no idea what Flinders Petrie or Howard Carter would make of the advances in Egyptology.
