We started this morning by opening a new locus (Locus 54) west of Locus 53, in order to see if the situation in Locus 53 continues to the west. The matrix in Locus 54 is a medium brown sandy clay loam with low to moderate gravel inclusions. We found a portion of a polishing stone (Ar/Ge.T31.54.L.01) at the southern end of the locus at 2282.23 masl.
I started to excavate the pit (Locus 42) in the LB floor. The pit is somewhat irregular in shape (a triangle with rounded edges). The pit is lined with rocks on the eastern side and is cut into the bedrock. The pit fill is a tan sandy silty loam, with chunks of clay in it, which are perhaps remains of a floor laid over the pit. I took a portion of the fill in the upper half of the pit as a macrobotanical sample (Ar/Ge.T31.42.MB.01). Halfway down, the fill changed to a medium brown sandy silty loam with low gravel inclusions. I took another macrobotanical sample (Ar/Ge.T31.42.MB.02).
