We're at the point in WSN now where all the work to be done inside the room must be done by trowel. In the course of troweling locus 38 to clean rocks we uncovered a relatively unlevel flagstone floor whose full extent is not yet clear (it seems to slope downwards towards the northwest). This work also gave rise to several questions pertaining to the line of stones that defines the southwestern limit of locus 41. Namely, this alignment of stones does not rest directly atop the flagstone floor. There is a fill of about 6 cm that separates the stones of this alignment from the floor. Moreover, several of the stones were not well fixed in place, raising some doubts as to whether this is indeed a feature. Given the distance from the floor, might we regard this as a secondary construction phase? Troweling work in this area of locus 38 also brought us upon a largely intact burnt wood beam that was extremely fragile and could not be removed in one piece. Perhaps there is still some hope for dendro analysis (will show to Sturt). I regard this sample as resting on the actual floor surface (i.e. in the matrix that sits immediately adjacent to the flagstone floor where slabs do not exist). It will be assigned to the floor locus once I finish troweling locus 38 (i.e. exposing the full extent of the flagstone floor in the north). While troweling in this north corner, we encountered an unusual, packed clay feature that has yet to be further explored on Monday. Meanwhile, we continued work in the small area of locus 31 in the east corner that remained to be excavated and we fully cleaned locus 42. A new locus created for the small sliver between locus 41 and 42 (43), which had very few materials. Other new loci today included 44 (for the top of the northeast wall) and 45 (for the small square area just to the northwest of locus 41. We are now at the level of the tarp from last year and, once completing locus 38, will expose the entire extent of the floor. We are nearing the end of this trench and have yet to make sense of the abundance of interior stone features, unprecedented compared to other rooms of Precinct A.
