Today we worked in WSI2 and took down the southeastern (upslope) half of the trench. In the east corner, we are seeing the lighter sort of "corner matrix" common to Tsaghkahovit, where the soil is more clayey, more yellow, and has some extremely tiny flecks of charcoal. This is locus 3, according to my system, and it's currently expanding underneath locus 4, which was the darky, loamy wash layer directly beneath the topsoil. Locus 4 is slowly receding toward the northwest, though it is deeper in the northwest than it was to the southeast, so I'm not sure if we will capture its extent tomorrow when we take down the northwest side of the trench. But we've exposed over 2 courses of the southeast wall, and about two of the northeast wall, though again, more in the east corner than at the extent of both walls. The northeast wall is locus 5, and the southeast wall is locus 6.
