This is a fill of cut SU621. After study, this cut (SU 621) is interpreted as relating to the construction of a hut. It is part of a set of features interpreted as the foundation trench and settings for upright posts that would form a hut or another small structure. The fill itself provides little chronological evidence. The interpretation and chronology has then been mostly inferred from spatial data and stratigraphic sequencing.

Probably natural accumulation within the cut of a posthole.
