“Sometimes, in archaeology, they discover something they can’t protect. They mark the site and rebury it in the earth, to wait for a day when they will have the proper funding, equipment, and techniques to excavate and protect the site properly. It’s called backfilling. Of course, they usually have to fight to do it. The local authorities want the site for tourism, other universities and archaeologists want it for study. Everybody wants to move too soon. And everybody overestimates their abilities to protect the site, to respect the science.”
