Deposit over the whole trench below the topsoil B-001 and above the level at which structure B-003 was identified. Moderately compacted silty clay. There is little indication that this deposit has been ploughed in the recent past. Fairly rich in Iron Age pottery, little or no non-Iron Age pottery, relatively little non-ceramic material culture. Trace amounts of slag, bitumen fragments and animal bone. 100% sieved
