Layer 4003 presumably a colluvial deposition after construction of wall 4004 on S side of layer. Entire layer is most likely a continuation of layer 4000 with inclusions and soil composition being fairl consistent in both layers. Drainage trench (4002) truncates 4003 on N side, separating 4000 and 4003. 4003 seems to cover wall 4004. Inclusions include bits of rubs, pottery and some bone isible in surface layer not excavated, but has been photographed, mapped and documented.
