Across WSN, we seem to be fast approaching the floor. In the east corner, I closed locus 33 and opened a new locus (42) to capture the matrix within the area defined by the lines of stones that run perpendicular to the northeast and southeast walls in this area. The locus ended in bedrock and an extremely packed orange clay matrix. We continued to work in locus 41, the sliver that runs parallel to locus 31, and here, too, bottomed out on stones across much of the area. While working in locus 38, we continued to evaluate which stones to remove (there are many) and which may belong to yet more internal stone features. We are no level with the tarp laid down at the end of 2010. Tomorrow I plan to trowel the entire floor and take soil samples. An exciting development in SLT-land today: Ian identified the location of the complete phiale found a few days ago as a burial. This is SLT15. It is a cist burial with at least two rows of small stones lining two sides, a flat stone on one end that appears to serve as a niche or shelf (on which the bowl was resting), and what appears to be an outer ring of larger faced stones surrounding the cist. Only a scattering of human bones found.
