We started the morning by clearing around the eastern wall, where the charcoal was found. We took a strip along the western edge of the locus down by 5 cm. As the soil along the western edge was still a medium brown and the soil along the eastern wall remains mottled black and medium brown, I decided to take the locus down 5 cm, using shovels. A C14 sample (Ar/Ge.T31.3.C14.01) was taken from a large beam found in the NW corner of the locus, at a depth of 2284.79 masl. A dendro sample was taken from the rest of the beam (Ar/Ge.T31.5). The beam section was about 45 cm long (including the staining of the soil, not just the actual charcoal). Another part of a beam was found along the eastern wall of the trench, in the SE corner of the locus. In the NE corner of the locus, we found a cubical (6-sided) polishing stone (Ar/Ge.T31.3.L.01) with rounded edges at a depth of 2285.00 m. Thus far, material densities remain low and the soil remains mottled. I decided to take the level down another 5 cm. In the process of doing this, shovels turned up a worked flake of obsidian (Ar/Ge.T31.3.L.02).
