Adam spent the day at Tsagh today. We continued in both trenches, WSC and WSJ. In WSJ, Adam suggested that the orange clay found in locus 3 and locus 4 may be melted mudbrick. I merged loci 3 and 4 because they are clearly one context. We worked in locus 4 for a while but have not yet reached the bottom of the orange clay and decomosed granite. It looks like the large stones on the south side of the trench are fall. Too large to remove. We'll probably have to break it eventually. In order to find the south wall, we decided to extend the trench 2 meters southward. The topsoil is locus 5. We stopped in the middle of the wash level, which is locus 6. In WSC we continued to clean and remove the fallen rocks in the north side of locus 2. Started a locus 3 across the whole trench, marked by a slightly lighter colored soil.
