Today we started taking down the area west of Locus 31, to see if the floor extends west. This is Locus 43. The matrix in Locus 43 is a medium brown sandy clay loam. There is a circular black stain just west of a semicircular arrangement of stones, which appear to be sunk into the floor, just about where the floor surface ends. North of there, at the end of the rocks/wall, there is a lens of orange clay (with no inclusions). West of where the floor ends, the matrix has a much higher level of gravel inclusions and is very hard packed in the upper portion of the locus. Just west of the rocks/wall, in the center of the locus, there is a lens of orange matrix with a high level of gravel inclusions. Directly north of this is a lens of orange clay, which also has a large amount of gravel inclusions.
In the SE corner of Locus 43, we found a portion of a groundstone (Ar/Ge.T31.43.L.01) at 2283.98 masl. We found another piece of groundstone (Ar/Ge.T31.43.L.02) south of the wall/rocks area, at 2283.98 masl. These were found above the level of the floor. On the western edge of the locus, in the center, we found a ceramic disk (Ar/Ge.T31.43.CO.01) at 2283.78 masl. The pit in the NW corner of Locus 31 is Locus 42. I took a C14 sample from Locus 41 (Ar/Ge.T31.41.C14.01), which will help us date the well-preserved level of the floor in Locus 31. We removed some of the small rocks at the south end of the wall/rocks area in the middle of the trench, in order to get a better idea of how many walls are in that area. The material cleared from between the rocks is Locus 44.
