The SU is a single vessel which was intentionally deposited. It is perhaps associated with the foundation deposit. The vessel continued for a short distance into the next deposit, a deposit that remained unexcavated in the 2015 season. When the excavation is reopened, this next layer should be given as the actual covering SU. During post-excavation study, this feature was reinterpreted as an intentionally deposited SU which might belong to the transition phase between Phases 1A and 1B.
