Today unfortunately was another short day, as we were rained out after lunch and had to pack up. The day was spent taking down Locus 2 in WSAD, and also continuing to take down Locus 11 in WSAC, with 6 workers. After a deep pass in WSAC a layer with more pieces of charcoal started appearing, but still in the same clay/organic matrix. I took one larger sample that stayed intact, Ar/Ts.WSAC.11.C14.03. The partition wall between WSAC and WSAD is starting to appear nicely but the area of rock fall in the southern corner of WSAC may in fact be blockage for a door, which Lori measured as similar to the doors in Precinct A, 1.4 m across. I declared the top of the wall Locus 3 and 4, with 3 being the area of the potential floor in the western corner and 4 being the northern part, although we didn't get to start cleaning it today (see notebook for sketch and elevations).
