Archaeology? Anuvver Name for Treasure Hunting, innit?

Picturing, of course, human remains, the Times' Arts Column journalist Richard Morrison (Jan 17th 2020) writes: ' The upheaval of HS2 is manna for treasure-hungry archaeologists'.

And how did archaeology come to be equated with Treasure Hunting? Answers on a postcard please. The UK should just get the metal detectorists to give the HS2 route a going over with their machines and, just like 'Brexit', the Treasures Mitigation will get done in no time. Shame about the skellies.
