Today we had Adam at the site mapping the remaining portions of Aragatsiberd (west and east slopes) while we removed sod from AB4 and continued lower in the AB3 locus 9 quadrant.Adam and I mapped the western and eastern slopes of Arabatsiberd today from benchmarks ABM6 and 5 respectively. We also shot in the corners of operation AB4 and the trench's two datums. It took approximately 700 points to finish the mapping. Now that the topography is recorded I will shoot the surface achitecture over the next two weeks and add it to the map (along with the operation bondaries).in AB4 we continued to remove the topsoil sods, working in the western portion of the trench. The easternmost and westernmost portions of the trench seem to be the most rocky, with much more maerial culture coming from the eastern half of the trench, accumulated uphill from the rocks. The southern portion of the trench also seems rather rocky.In AB3 we continued to descend in locus 9, above the ostensible northern edge of the LB floor, abutting the locus 4 wall. We ran into additional wall stones all afternoon and this considerably slowed our downward progress. We uncovered what appears to be two courses of wall stones which are either a lower (and more southerly) extension of the locus 4 wall or a new lower wall running east-west into the eastern baulk. Two stone tools were recovered from the space between the eastern half of the locus 4 wall and this new architecture (now locus 10). The locus appears to be close to the same depth as the locus 6 floor in trench south.At the southern margin of locus 9 a black, burned lens is visible in section, sloping westward from the eastern baulk wall fall and under the basin, towards the locus 6 floor. This lens may suggest an LB destruction level, but more work is needed to confirm and explore.
