This locus captures the NW 3 m of WSDB\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s extension to 7.5 m. It includes the wash layer around the two rocks that leaned SE over the burial in Locus 18 (human remains = Locus 20). Its soil is rich, dark, loamy, with not a lot of material. The locus was extended to cover the entire third extension of the trench after the N corner was dug down to the point where the soil matrix was the same as further to the west. Two human teeth were found in this locus, at 2137.475 m.ASL, and 60 cm from the NW baulk (at the 3rd extension, to 7.5 m) and 60 cm from the NE baulk. The closing elevs: N: 2137.505; W: 2137.405; S: 2137.435; E: 2137.555; center: 2137.405. The closing dimensions were 1.8 x 1.5 m, from the line of the \\\\\\\\\\\\\\\"burial chamber\\\\\\\\\\\\\\\" to the NE baulk. While it is a wash layer, it was in the room, and because of the human teeth, we should reconsider its stratum. The uncertainty of the stratum means its material was saved.
