Dense concentration of small-med tile and stone continuing under bulk to E and N- will wait to remove until we join areas 15000 and 16000. Poorly preserved collapse under plough soil and covering wall 16004. Waited to excavate in hope of following SU to NE into 15000. Decided to remove to expose top of 16004 wall. Does not appear to belong to same collapse event as 16016 and 16017.
SU 16007: view toward the north
