Today it finally seemed like we were reaching a new level in the soil matrix, and we should reach cultural levels soon. A redder, clayish soil has clearly emerged on the SW wall, and there are traces of it along the NE edge of the trench as well. There is still a lot of rock fall to deal with, however. Locus 9 was closed today, but locus 8 was resized to incorporate everything between the NW edge of the trench and locus 9. There may also be signs of a doorway on the SW wall, though it is too early to tell for sure at this point.
