The excavation of Grid 16 is well under way. They have architecture -- a remnant of a possible floor and a line of stones which might just be another drain -- and big holes, as you can see below.
Emily is standing on top of some geotech. All the dirt on top of it? Backfill covering last year's excavation. It's a benchmark as they work to expose a mudbrick wall (possibly a fragment of a rampart) first uncovered last year. And how do they plan to move all that dirt?
By hand, of course. With Josh to haul the dirt for the grid, nothing else is needed.
