This SU appears to be a deposit of soil. We did not fully excavate the soil in this SU this 2017 season because underneath this SU, there are three other visible patches of layers. The next SU appears to be collapse. Underneath the collapse is what appears to be an extensive mosaic. At this time, only the black border was visible. In areas where the mosaic tesserae have been removed, a smooth prep floor layer is visible. Patches of all three layers were visible in various places underneath this SU. In order to protect the mosaic, which cannot be excavated this season due to time constraints and conservation concerns, the soil from this SU was not fully excavated and will need to be removed next season.
