With a shortened day today due to the visit of the American ambassador and our inter-village football game, our work was reduced to about 3 productive morning hours. We spent a large portion our first hour cleaning the trench and removing garbage from the trenches and hillside. Work proceeded until lunch in the locus E664 sandy silt fill with incredibly low material densities. I'm considering halting our screening of this matrix. In locus E658 we continued to descend among the silty brown matrix with moderate material densities, but certainly unimpressive amounts of material for the size of the locus.
