In WSN, we continued to work in loci 64 and 65. In 64, I dug the interior of the hearth-like feature down to a sterile clay deposit. In locus 65, we excavated the clay deposit whose limits we labored to define a few days ago. For it became clear that this clay did not constitute the edges of a pit or any other definable feature, but was instead perhaps a kind of deposit placed within this larger feature. Was this a place of pottery production or some other place in which to store or dispose of excess clay? This would explain why its limits do not conform to any recognizable feature. The stratigraphic situation of the deposit was as follows: a thick deposit of loose (or rather not packed) yellow/tan clay of about 27cm thickness; above this, a thinner deposit of organic or burnt/black clay/silt; above this, the packed tannish clay of the floor. I photographed the section and dismantled the deposit. The clay was sterile. In WSM3 today we created a new locus for the poorly constructed wall that blocked the entrance to the passageway seemingly leading into room O. This so-called wall was in fact floating above the level of locus 3 in WSM3, so absolutely above the level of the floor in room M. It is almost certainly some sort of later build, and a quite flimsy one at that. After photographic, we dismantled the wall and exposed the well-built passageway into O (also removing the 5 rocks that were floating in WSN locus 100/101. I also kept busy today reading pottery from WSAC2. Today was a happy day for our workers--pay day!
