Spent the day working in operations 10 and 14. In 10, created loci for the two walls. Hard to say whether the two large boulders of locus 07 belong to the wall. Masonry is considerably different from the smaller, flatter stones below. In operation 14, worked in locus 08 and created new loci for built features, 09 for the long, W-E wall and 10 for the short, N-S wall. Locus 11 was the sliver to the south of the long wall of locus 9 and east of the wall of 10. Today an interesting cluster of artifacts emerged from the northwestern corner, an area of about .15 by .15 cm. Some bone. Large obsidian. A shell. Will investigate further tomorrow.
