Started the day off finding a large C14 sample in the center of L105, which was the remains of burnt wood and possibly a beam. This is a large and good quality sample, and should help to date the EB surface which this sits on, and can also provide a terminus post quem for the constructions which are built above this layer. It was from an elevation of 2295.357 m, 1.36 m from the N baulk, 0.65 m from the western edge of the locus, and it is sample Ar/Ge.T22.105.C14.06. We began screening all remaining soil from L105, since this beam suggest that we are on, or just above an EB surface. This surface may be the natural/bedrock, which has begun to appear the in the NW corner of the locus. We will continue to bring the locus down tomorrow, hopefully reaching bedrock by the end of the day. Along the eastern edge of L105, and in L103, a second large stone has appeared in the south-eastern corner. It lines up with another large stone to its north, and may line up with walls visible in T20, further to the south. The stones are approximately 80 cm x 80 cm. Just to the east of the southern-most of these stones, Arthur found a small (c. 15 cm in diameter) hole beneath a rock-pile we removed. This is a strange feature, since it is not filled with anything (not even soil). It may be lined with small pebbles, and is about 25-30 cm deep. Not sure what this is. After lunch we photographed the top course of the wall between 2008’s T22 and 2010’s T22, and then removed the upper course of stones in order to better understand the wall and its dating. In some ways, this wall seems to have had a few use-lives, though at this point, without seeing the different faces, and dismantling it, it is difficult to say for sure. I opened L106 as the cleaning layer which exists beneath this top course, and also will include the soil between the second (from the top) course of stones. More on that tomorrow. Two charcoal sample (Ar/Ge.T22.106.C14.01 and Ar/Ge.T22.106.C14.02) were taken from this layer.
