Paved floor in WSAC2, extending just before Feature 15 to the NW baulk, the NE baulk, and stopping before the doorway in the SW wall. Large, well positioned limestone and basalt stones that are also well-preserved. Exposed 16/7/11. Roughly 7 meters in length, running from NE baulk to right before the SW wall, and 2.8 meters at its widest. Most of the stones were exposed by 18/7/11 except those beneath Locus 26, which are at a lower elevation, and seem to indicate an intentional stepped feature of the floor, leading to Feature 15 against the wall. Elevation given is a stone about 2.5 m from the NE baulk. Photographed 19/7/11.
