Spent much of the day troweling in locus 07 of T05b. Finally came on bedrock, but not before first excavating a burnt beam, which is the second C14 sample from this locus. The beam continues under a part of the pile of rocks in the western side of the trench, but perhaps not very much of it remains to be recovered. The trench would need to be expanded significantly, which is not a goal for this year. In operation 06, we unexpectedly came upon bedrock at the bottom of locus 06. Very odd. Clearly the wall is only a terrace wall, but not associated with any upslope, internal space/architecture. Tomorrow will open a new trench, or perhaps two.
