ET 01: Finishing up locus 3 today, as we do so revealing a wall in the north section, particularly the northeast.
Finished locus 3 and begun locus 4, which seems to sit on top of bedrock, although we have only cleared about 1 square meter.
Actually locus 4 sits both on top of floor and on top of bedrock. Having established this, we cleared the whole trench to within a few centemeters of the floor, and tomorrow will see if we can clear the floor.
