Today we started by finishing Locus 47. We then started a new locus (Locus 48), which is again the area west of the LBA floor. The matrix in Locus 48 is a medium brown sandy clay loam with moderate gravel inclusions. Along the eastern edge of the locus, there was again the light brown matrix. It became apparent as we continued down in the locus that the light brown matrix is under the medium brown matrix, but at a steeper angle than I previously realized. Thus Locus 47 and Locus 48 are the same matrix.
There is a small, irregular pit in the NE corner of the locus, the top of which is at 2283.68 masl and the bottom of which is at 2283.58 masl. The pit measures 30 cm x 20 cm. Given the irregular shape of the pit, its small size, and the high level of gravel inclusions (and their large size), it seems likely that this was actually the remnant of a completely eroded rock. We found a very large groundstone (Ar/Ge.T31.48.L.01) in the southern end of the locus at 2283.64 masl. Underneath this groundstone, we found a large number of sherds. We found another groundstone (Ar/Ge.T31.48.L.02) near the center of the locus, at 2283.66 masl. In the SW corner of the locus, we found a piece of groundstone (Ar/Ge.T31.48.L.03) at 2283.58 masl.
I started a 1m x 1m probe in the SE corner of the LB floor (Locus 49). Underneath the clay of the floor, there appears to be bedrock, at depth varying from 5-12 cm. The clay itself is very mottled in color (light tan, orange, medium brown, black) and there is the occasional bone, sherd, or piece of charcoal. I took one of the larger pieces of charcoal for a C14 sample (Ar/Ge.T31.49.C14.01). This piece was ~2 cm above the bedrock.
