Continuation of darker soil in WSAC3, confined by the center of the operation, along the NW wall and the SW wall in the western and southern corners and along the wheelbarrow ramp. Underneath Locus 3. Matrix is slightly looser than Locus 5 to the NW. Opened 28/7/11 and came down on a linear feature about 1.5 m SE from the NW wall of the room, parallel to the wall, with a right angle running N-E. Soil to the S of these linear features is black. See notebook for sketch and elevations (sketch from 27/7/11); given is NW of center. Included some of the shortening of the wheelbarrow ramp in this locus 29/7/11.
