SU 10066 represents a reddish surface extending from the cut 10054 to the basalt boulder 10060. 10066 was not particularly deep, extending only approximately 20 cm, before we encountered layer 10069 underlying 10066. 10066 remained relatively loose, and had only moderate amounts of cultural material in the soil matrix. Because of the small area within which we were able to excavate, it was difficult to discern what the purpose of 10066 would have been, although it does seem to be associated with the insertion of the cut sandstone blocks 10058.
