Excavators cancelled this SU after they realized that there was no convincing cut. While the cut will remain cancelled, I have re-opened it, however, since there is material associated with it. Based on the lack of materials other than a couple of metal nails, I am equalizing this with 10121 above it, part of the collapse of the structure.
Excavators initially thought this might be a fill for a cut into the surface/occupation level, but it is now thought instead to be the first pocket of occupation uncovered, that was simply less solidly covered by the wall collapse.
