AM We took down locus 1 in AC4, which is full of dark topsoil and hand-sized rocks, few materials. Finished this locus (with picks and shovels) by 1 pm. Drew the architecture in AC1, including half of the paved floor. Cleaned the AC1 baulks. Troweled back half of the section of locus 12 in AC2, exposing some burnt lenses, one of which I sampled for bot.
