We continued to excavate the wash level of C8. Changed to locus 3 when we encountered a tan clay surface. We concentrated on the se side of the trench. Here we uncovered a series of aligned rocks, although it is not clear what sort of structure this is. We also encountered a darker, more organic soil. In some cases it is embedded within the clay layer, in other cases it might be above the clay. This darker soil is evident in the profile in the west quad of the trench. We will start a new locus here tomorrow. Had one spindle whorl and a fragment of a mortar. Also, one sample of burnt bone. Vartan came late today, and was not permitted to work.
