Split workers for the first two hours in the morning a) excavating Locus 20 near the SW wall and the rock jumble and b) cleaning the top of the SW wall (Locus 15). While they were doing this I drew the paved floor, feature 21 in the eastern corner, and designated Locus 22 as the visible clay floor between the linear stone feature and the paving stones. This locus therefore constitutes the bottoms of Loci 14, 18 and 19. The paved floor (16) now stretches down the SE baulk from WSAC2 and about 3 m to the west, where there is potentially a door in the NW wall, under the wheelbarrow ramp and the huge jumble of stones in the southern corner. In the morning I had the guys clean and sweep the surface and the stones and took photographs of 16, 21 and 22.
I had three guys start troweling the surface of Locus 22 before lunch, and the matrix consists of a mixture of grayish and orangish clays, really hardpacked with flecks of white and charcoal, with looser areas of organic-rich material and more charcoal. There are also areas of a gritty, almost sandy orange type of soil which I have not seen before in the clay floors in WSAC and WSAC2. I'm not sure if this means in the area near the potential 'pathway' to the door and the linear stone feature (10) that there is some sort of pit or hearth feature/firing area, or if the floor here is just not preserved. Got some good charcoal samples from this locus as well as a large piece near one of the outer stones of Feature 21. We did this for most of the afternoon, and I had Arturik start troweling between the stones of the paved floor (16) to clean this up. At the very end of the day Lori came by and we discussed again the plans for the next three days. She suggested blitzing the rock jumble in the southern corner with her and Jake's workers, since WSAC2 and 3 are the priority for Lilit to draw. This would clear up more of the paved floor and also the question of the clay floor along the SW wall in WSAC2. She also suggested taking off some of the obviously out-of-original-context stones on Feature 21, amounting to about 5, which we did and cleared up the large flat trapezoidal stone underneath.
I didn't really have a chance to look at the results of excavating Locus 20 near the SW wall but Lori thinks they might have reached a sterile clay.
