A block of unknown purpose. Possibly merely related to post-abandonment accumulation or the intentional depositions or dumping activity in this area. Alternatively, it may be connected with the second phase of occupation in this area, and linked to the features immediately to the east and south (wall 5744 and hearth 5577/5745).
