8.11.06 I closed Locus 4, inside the room in WSC3, and have split it into Loci 5 and 6. Locus 5 is along the SE and NE walls, where we are beginning to find some sort of clay surface. Locus 6 is still the wash level above this clay surface. Locus five has a mottled surface with pockets of white clay, a clayey orangeish soil, and some darker mottling. Fairly productive day, but more work needs to be done in both Locus 5 and Locus 6 tomorrow.
