We started the day by keeping excavating locus 4 in front of W1 in order to clarify the situation with W1. The latter seem to have at least three courses of regular sub-rectangular stone blocks, but we haven't reached the foundation of the wall yet and no floor associated with this feature has been detected so far. Since the area of T46 is quite limited, we decided to expand the operation by another 1m along the E side of the operation and half way through the N and S sides of the trench (see notebook for a sketch of the new expansion).
