Small cobble wall emerging from north baulk, as a continuation of SLT9:loc 9 wall. This wall seems to abut large loc 13 wall dividing locus 9 and 14 floors. East of this little wall, the bedrock slopes down, so it does seem to function as a spatial division of some kind. Not clear yet how or why yet. C14 dates of the floors it is on will help determine Stratum assignment.
