The eastern limits of the floor (SU 2202, SU 2253) are truncated, but a specific cut has not been identified or assigned. SU 2305 appears to be a natural, post abandonment accumulation layer. Yellow soil patches and vertically deposited rocks are visible on the western edge of the layer. These appear to continue below the floor (SU 2202, SU 2253) and may be archaic. For this reason, SU 2305 ends at the depth of these patches.
