This wall collapse is roughly lunate/convex in shape with the farthest western stones at the northern and southern extents of the collapse SU. The eastern extent is the wall SU 16003 and much of the western facade of the wall. There is a significant amount of mortar along the outside of stones still in situ in the wall (fill of the wall) where the facade stones are imprinted. This mortar was removed by Dora to help find the limits of the wall SU 16003. (ELM)
