A single linear cut that, at the time of the event, was carved into three circular cuts; these were stepped; the topmost was the southern cut, the next the middle, and the lowest the northernmost. This northernmost limit was truncated by the construction of T.52. This feature may have been a foundation trench for a wall (made of perishable materials) or a trench for postholes. May be in alingment with a N/S feature that runs along the western portion of the area in a N-S direction.
