By "the location and surroundings" I don't just mean the farmstead or whatever. I mean things like the cubic centimeters of dirt immediately around, above and just below the object, recorded in meticulous detail. You know, all the stuff you've just dug through to get to it. People elsewhere are complaining about how long digs take, but have you ever seen an archaeologist's toolset? They "dig" sometimes with a sharp flat trowel but mostly with a tiny little paintbrush. The "dig carefully" of a hobbyist spending a fun couple of hours on a Sunday with their metal detector and shovel is not the "dig carefully" of an archaeologist with their six-month grant, tiny trowel, ruler, calipers, camera and 1/4" sieve for the dirt.
