I changed the dimensions of operation WSM3 today, extending it to the northwest, to align with the northwestern limit of WSN. I then created a new locus for the removal of the sod and dark silt overburden in the area of the "extension" that falls within the space of the proposed passageway into WSO, designating this as WSM3.04. For now, we will not remove the sod in the remainder of the operation (i.e., the remainder of the extension). Locus 4 proved rocky, though most of it clearly fall except for the area adjacent to the presumed closure along the northwest wall of what was previously WSM3. Tomorrow I will likely photograph and remove this closure so as to expose the passageway. In WSN today, I resumed work in the area of locus 65. This entailed, in the first instance, creating a new locus, 70, for the small space between locus 64 and the previously excavated limit of locus 65, that is the space that Adam regarded as possibly containing some slag associated with metalworking. The locus was a mix of orange clay and medium brown earth and chunks of what appear to me to be decomposing rock (though will sample to pursue the slag possibility). After bringing locus 70 down to the existing elevation of locus 65, we further expanded locus 65 to the southeast in the hopes of gaining some clarity on the feature (is it a pit? Is it a fill level of some sort with a lower floor beneath?). The situation is still uncertain. But it was complicated by the fact that today we found a complete vessel, a small jar, seemingly floating in this mixed matrix of sterile yellow/tan clay and tannish/brown silty clay. The form of the vessel is not particularly diagnostic to my eye, but will see what others say. I doesn't appear to be LB. Contents not yet removed. Will continue to work here tomorrow. Also today, I started reading the pottery from WSAC2 in the field.
