Jumble of large and medium sized rocks in the southern corner of operation WSAC3, against the SW wall and the SE edge. (Some smaller rocks were noticed on the other side of the baulk in WSAC2.) Its possible that these are wall fall, or just the natural sliding of the rocks over time and collecting against the wall. Some of the rocks toward the NW are sitting on soil which is on top of stones of the paved floor; when the jumble was taken out 6/8/11, more paved stones appeared which continue from WSAC2 but leaving a gap between this floor and the SW wall. Three large boulders which appear to be in some sort of alignment were not taken out, all of the rest were removed after drawing and photographs. The soil between and under the stones was screened as this locus. See notebook for sketch and elevations; given is the top of the central stone.
Three large boulders were broken and removed 9/8/11.
