Spent most of the day dealing with locus 5 in WSL. At this point we're just troweling. The clay and plaster surface is not level and it seems to drop off towards the NE. Clay can still be seen in this direction but not the plaster. Also, to the NE the clay is less thick and not as packed as it is to the SW. Instead, here there is more of a brown silt. Material quantities quite high here. We uncovered stones to the NE, but I don't think it's a stone floor. The rocks are not flat enough and there is too much space between them. But it's some sort of feature. Not fully uncovered yet. This could be a prep surface for the floor above but I don't think so. By the end of day we had two levels in the trench. To the SW, the white plaster and clay floor with its own irregularities (including a few depressions.) Then lower down to the NE is the thick brown silt interspersed with clay and semi-flat stones. In WSK we took locus 4 down to bedrock along the NW wall. Not necessary to take the clay down across the entire trench. We also extended this trench to the NW to try and expose the external course of the wall. This is locus 6. I think this is a double faced wall, but not rubble core. At this stage there's only one rock in the middle. Need to trowel in here some more.
