Created several new loci today. Started in locus 3, in the s side of the trench, where we excavated through much of the tan clay until we encountered several rocks. Some seem to be aligned with the wall in C7 and C3. Others might constitute a stone floor. Some flat stones were uncovered at a slightly lower elevation than the rest. Not yet clear what these structures are. We then created locus 4 on the n side of the trench, which is demarcated by a dark, organic soil. It was a shallow locus. We changed to locus 6 as soon as we encountered the tan clay in much, but not all of the n side of the trench. Finally we created locus 5 in the south quad of the trench - the area marked off by a series of stones. Small finds today included a mortar, pestle, bone artifact.
