Cluster of stones south of SU 7131 deposited around "pipe" 7138 at northern end of slab 7137. Seems to be an intentional deposition, possibly related to a kind of crude structure to protect the ceramic pipe (cf. SU 7138). Below this cluster of stones was found a cut into slab 7137, filled with loose silt around the pipe.
